Coal, as known as the food of industry, has an indispensable role in the development of the national economy. Affected by the development of new energy technology and economic development and policy, in recent years, the growth of consumption of coal as an energy source has slowed down, but production and consumption are still at a historical high, and production and sales are still very huge. Coal carbon whether in the production or use process, will produce a mixture of water and fine coal dust, such as coal industry coal washing wastewater, coal preparation plant slurry water, coal-fired power plant flushing wastewater, etc., and these coal washing wastewater mixtures are mainly characterized by the following: 1. high turbidity, fine particle size of solids, solid particles more negatively charged on the surface, due to the repulsive force of the same sex charge asked as well as by gravity and Brownian motion, so that these particles in the water to maintain the state of dispersion;. 2. Due to the interaction between the interface of solid particles in the coal slurry water (such as adsorption, dissolution, synthesis, etc.), so that the nature of the coal washing wastewater is quite complex, not only with the nature of the suspension, but also with the nature of the colloid. 3. The sludge resistance is large, the filtration water is poor, and the pressure filtration dewatering is difficult. Therefore, the coal wastewater is particularly stable, standing for several months will not naturally settle, it is difficult to naturally clarify, after precipitation supernatant still with a large number of coal slurry and other suspended black liquid, and contains a variety of additives in the production and processing and heavy metals and other hazardous substances, so it is very difficult to deal with. If these wastewater is discharged according to the standard, it will cause water pollution, siltation and loss of coal sludge, which not only cause environmental damage and waste of resources, but also cause huge economic losses. The good or bad of wastewater treatment seriously affects the development of the coal industry. Therefore, in the face of coal washing wastewater, the development of new products and new technologies is of great significance. Aiming at these characteristics of coal washing wastewater, we summarize the following coal washing wastewater treatment methods through a large number of experiments: Firstly, add lime or calcium carbide slag into the wastewater (the composition is calcium oxide), neutralize the negative charge in the wastewater, destroy the stability of the water body, and achieve the purpose of mud-water separation. Secondly, add flocculant (polyacrylamide), after adding calcium oxide treatment of wastewater suspended matter settling speed is very slow, complete precipitation is difficult to realize, it takes a long time, because the polyacrylamide has a very long molecular chain, the molecular chain with different groups, the long molecular chain can absorb suspended particles collide with each other to form larger flocs adsorption settling, so add the polyacrylamide can increase the settling speed, so that the mud and water to achieve complete and rapid separation. Therefore, the addition of polyacrylamide can increase the settling speed, so that the mud and water can be separated completely and quickly. According to years of experience, coal washing wastewater treatment generally use anionic polyacrylamide or nonionic polyacrylamide, there are very few use of cationic polyacrylamide. It is recommended that when you use flocculants, you must first do the selection of flocculants to avoid unnecessary waste. Polyacrylamide flocculation product features 1.Can quickly form large flocs, sludge volume is small and fast flocculation and settlement; dissolve quickly and thoroughly, no insoluble matter (fish-eye); powder state products dissolve in 60 minutes or so; economical and practical, small dosage, good effect, high rate of dewatering 2.Low operating costs, low dosage can produce effective effect well and high performance of dehydration, very economical; excellent filtration and dewatering to improve the dewatering effect of sludge, can be automatically fed, easy to deal with. Product selection can be used exclusively for high viscosity of the water bath liquid state, is very good fluidity viscosity of the gel reduction system. Need to pay special attention to: Polyacrylamide aqueous solution additive amount is the key link in the coal slurry wastewater water treatment, take the right way to add, add the right amount, will help to improve the flocculation effect. Usually according to the selected coal sludge water treatment process and the nature of the coal sludge water through the test to determine. If the dosage of polyacrylamide is too small, it will lead to slow sedimentation of coal slurry, and the concentration overflow will exceed the standard very easily, which can't guarantee the required index of circulating water, and thus make it difficult to control the index of coal washing products stably. If the polyacrylamide dosage is too much, although it accelerates the precipitation speed of coal slurry, but it is easy to cause the concentration of concentrated underflow is too high, and the content of polyacrylamide in the underflow increases, resulting in difficulties in the transportation of the underflow and filtration, and it is not easy to dislodge the coal cake when unloading the coal cake in the filtration, which increases the operator's labor intensity, reduces the work efficiency, and results in the waste of pharmaceuticals, and makes the production cost increase. Therefore, the test to determine the appropriate amount of polyacrylamide, not only can improve the flocculation effect, effective treatment of coal slurry wastewater, but also has an important role in coal quality and production efficiency and reduce production costs.

When it comes to natural gas, you must not be unfamiliar with it, and nowadays no household can cook without it.The main component of natural gas is Methane, which is one of the simplest Hydrocarbon Compounds. Accelerating the development and utilization of methane is the key to realize the green and sustainable development of energy and chemical industry. In addition to its direct use as a fuel, methane can also be used as a C1 resource, that is, a molecule that contains a carbon atom and can continue to be converted to prepare high-value-added chemicals, such as methanol, formic acid and so on. Methane can be burned in oxygen to form water and carbon dioxide. Without combustion, is it possible to activate and convert the hydrocarbon bonds of methane molecules under mild conditions? The answer is yes! This is the "Holy Grail" reaction in the field of catalysis. Reactions associated with the "Holy Grail" are often extremely challenging, as they may need to be carried out under very harsh conditions, or they may need to overcome the inherent difficulties of a chemical reaction, such as the activation of highly stable compounds, low yields, and low selectivity. These challenges make it difficult to realize these reactions, but if they can be successfully achieved, they will lead to significant breakthroughs in scientific research and industrial applications. 1.Challenges in the conversion of methane at low temperatures It is very difficult to convert methane directly to other useful chemicals with inexpensive oxygen at low temperatures or even room temperature, why is that? Let's look at the nature of methane and oxygen. The chemical structure of methane contains four identical carbon-hydrogen bonds (C-H) that form a highly symmetrical orthotetrahedral configuration, and each CH3-H bond of methane has a bond energy of up to 435 kJ/mol. We can think of the C-H bond of methane as a particularly strong spring. This spring is very taut and requires a lot of force to stretch. In chemistry, this "force" is the energy required to break the C-H bond. This high bonding energy makes methane's C-H bonds thermodynamically stable and very difficult to break down or react with under normal conditions. On the other hand, in chemical reactions, reactive groups are usually generated under polar interaction (polar interaction is the phenomenon that a molecule has one end positively charged and the other negatively charged), whereas the symmetric structure and nonpolar nature of the methane molecule prevents it from generating such polarity (according to the molecular configuration, a molecule with a symmetry plane has no polarity) and cannot provide reactive groups. Therefore, the activation and conversion of methane is very challenging and usually requires harsh conditions such as high temperatures (600-1100°C) or some "extremophiles" such as super-strong acids and free radicals to assist in the activation of methane. Therefore, the main difficulty in realizing the low-temperature activation of methane and oxygen lies in how to activate the C-H bond of methane, i.e., how to stretch the "spring" in the C-H bond. 2.The miracle of catalyst Scientists came up with a good solution to this problem, and chose to use a catalyst to help activate methane at low temperatures (a catalyst is a chemical that does not change before or after a reaction, but speeds up the reaction by altering the minimum amount of energy that needs to be injected for the reaction to take place). In 2023, the journal Nature Catalysis reported on the process of achieving the direct conversion of methane with oxygen to C1 oxides (methanol (CH3OH), formic acid (HCOOH), and methylene glycol (HOCH2OH)) using a specific molybdenum disulfide (MoS2) catalyst at 25°C. A methane conversion of 4.2% and almost 100% C1 oxygenates were achieved by turning methane and oxygen into valuable C1 oxygenates under ambient conditions. This MoS2 is the only catalyst reported so far that can realize the room temperature conversion of methane and oxygen. This is all due to the unique geometry and electronic structure of the Mo site on the edge of the MoS2. This Mo site has a high activation activity towards oxygen in an aqueous environment, forming the magical O=Mo=O* species. This species makes the carbon-hydrogen bond easier to break and reduces the activation energy of the C-H bond of methane, thus greatly increasing the reactivity of methane, and thus realizing the low-temperature activation of methane and oxygen. This discovery will bring more possibilities for future energy utilization and environmental protection, as well as giving us a deeper understanding of the amazing role of Catalysts And Auxiliaries. 3.Significant strategic significance of low-temperature activation of methane Realizing the direct catalytic conversion of methane and oxygen at room temperature, and converting methane in natural gas into other useful chemicals, can greatly improve the utilization rate of natural gas, reduce the waste, and better protect the environment and realize the sustainable development of energy. Secondly, as a greenhouse gas, methane is second only to carbon dioxide in its contribution to global warming. If methane can be converted into other substances, it can help us to reduce the emission of air pollutants (e.g. carbon oxides, nitrogen oxides, sulfur oxides, hydrocarbons, and Ether Compounds) and ease the pressure of global warming.

The compatibility of the Hydrotreated Petroleum Resin and elastomer is an important factor affecting the adhesive strength of hot melt amines. Compatible tackifier resin and elastomer can reduce the amount of colloid energy storage film, and under a certain stress, the colloid is fully bonded with the adherend; if they are incompatible, the amount of colloid energy storage film will increase, which will reduce the adhesion between the colloid and the adherend. The compatibility of a tackifying resin with a polymer matrix is a physical quantity related to its polarity and the relative molecular mass of the resin. If the polarity is the same and the relative molecular weights are similar, compatibility is good. For example, aromatic plasma styrene (P3) is incompatible with natural sassafras rubber, but compatible with aromatic butyl rubber gum; polyvinylcyclohexane (PVCH) with an average molecular weight of 650 is compatible with natural rubber, but PVCH with a relative molecular weight of 1,800 is not compatible with natural rubber. Hydrogenated petroleum resin is a low molecular weight functional resin, its molecular weight is generally less than 2000. Its molecular weight is generally less than 2000. it is thermoplastic, soluble in organic solvents, especially petroleum solvents, and has good compatibility with other synthetic resins. It has excellent water resistance and weather resistance. Its main performance indexes include softening point, color, unsaturation, acid value, saponification value and density. Softening point is an important property of hydrogenated petroleum resin, which reflects the hardness, brittleness and stiffness of the petroleum resin. The softening point of hydrogenated petroleum resins for the rubber industry is generally 70°C~100°C, and that of hydrogenated petroleum resins for the paint industry is 100°C~120°C. Color is another important characteristic index of hydrogenated petroleum resins. Light colors are used in the paint and coating industry, intermediate colors are used in the printing industry, and dark colors are used as rubber additives.

Aluminium Sulfate is a common inorganic compound with a wide range of applications and multiple effects. It is a salt compound composed of aluminum ions and sulfate ions, with the chemical formula Al2(SO4)3. several major effects of aluminum sulfate will be introduced below. First of all, Aluminum Sulfate plays an important role in Water Treatment. Due to its good flocculation properties, it can rapidly precipitate suspended and turbid substances in water, thus making the water clear and transparent. Therefore, aluminum sulfate is often used as a Flocculant for water purification, sewage treatment and industrial wastewater treatment and other fields, effectively removing impurities and pollutants in the water. Secondly, Therefore, Aluminium Sulfate also has a certain antibacterial effect. It can destroy the cell wall structure of bacteria, inhibit the growth and reproduction of bacteria, thus playing the effect of sterilization. Therefore, Aluminum Sulfate is often used in the field of medicine as a common antimicrobial agent for the treatment of skin infections, burn wounds and other diseases. In addition, Aluminum Sulfate has an astringent effect. It shrinks the skin tissue and reduces the dilation of pores, resulting in firmer and smoother skin. Therefore, aluminum sulfate is often used in cosmetics as a common astringent for conditioning the skin and improving skin texture. In addition, Aluminum Sulfate can be used to prepare other compounds. For example, it can react with alkali metal salts to produce the corresponding sulfates. Aluminum sulfate can also react with other metal ions to form precipitates or complexes. These reactions are often used in chemistry laboratories to analyze and synthesize other compounds. However, it is important to note that there are some potential risks associated with the use of Aluminum Sulfate. First, Aluminum Sulfate is corrosive and contact with skin and eyes may cause irritation and burns. Therefore, when using aluminum sulfate, care should be taken to wear protective gloves and goggles to avoid direct contact. Secondly, the amount and concentration of aluminum sulfate should be controlled according to the specific situation to avoid overuse or high concentration, so as not to cause adverse effects on the environment and human health. In summary, Aluminum Sulfate is a compound with a variety of effects. It has a wide range of applications in water treatment, antibacterial, astringent and chemical laboratories. However, when using aluminum sulfate, we should also pay attention to the safe use to avoid adverse effects on the environment and human health.

Coal mining industry will discharge a lot of coal mine water during the production process, without the solution of immediate discharge, not only lead to environmental pollution of the environment around the mine, but also consume a lot of precious water. The use of coal mine water source is to deal with the coal carbon plantation area is relatively serious less water and coal mine water pollution, the two confusing coal enterprise development trend of the difficulty of the basic clearly put forward. The process of coal mine water treatment depends on the way it is used, and the main solution for coal mine water is to remove suspended solids, various positive ions and other residues in the water. The basic process is to remove suspended solids, positive ions, and other residues from the water, so that it can be used for domestic or industrial purposes, and the basic process is concrete, sedimentation, filtration, and sterilization. Among them, the concrete (inclined plate sedimentation tank) solution is one of the key processing techniques in all the steps of coal mine wastewater treatment, and the selection of coagulant and the concrete experiment are the key criteria to ensure the actual effect of coal mine wastewater treatment. Different coagulant concentration value of coal mine water concrete actual effect of harm, in a certain concentration value category along with the concentration value of the elevation of the sludge load of coal mine water turbidity, different coagulant mud amount of coal mine water turbidity sludge load of harm, coal mine water quality sampling turbidity sludge load along with the elevation of the amount of coagulant mud to expand, when done to the highest value and then there is a reduction of the whole process. It is because of the coagulant mud amount is not enough, coagulant can not be sufficient with the suspended solids in the water to touch the reflection, water quality sampling in the suspended solids are still part of the suspended solids, and when too much coagulant application of colloidal solution particles to carry a positive charge, so that the colloidal solution particles in the middle of the electrostatic induction repulsion to enhance the suspended solids are once again in the smooth situation. And then cause the turbidity of the supernatant left increased. Sludge load is reduced; in addition, too much coagulant also "encapsulate" the particle surface layer, this kind of "encapsulation" effect weakens the cohesion between the particles work ability. When the concentration of suspended solids in the coal mine water is very low, the colloidal solution needs less positive charge, and the amount of coagulant can complete the colloidal solution electro-neutralization and destabilization when the amount of coagulant mud is relatively small, along with the expansion of the value of the concentration of suspended solids in the coal mine water, the total number of positive charge needed for the colloidal solution is expanded, and in order for the colloidal solution to achieve the effectiveness of the electro-neutralization destabilization of the suction, the amount of coagulant will be raised in relative terms. Harmfulness of pH value to turbidity sludge loading The sludge load of turbidity in the water quality sampling of coal mine water expands and then decreases with the expansion of pH value because pH value harms the zeta potential difference of the colloidal solution or the surface layer of the particles in the water, the hydrolysis reaction of the coagulant aid, and the shape of hydrolysis reaction substances, which immediately jeopardizes the actual effect of the coagulation and precipitation. The harm of coagulants and coagulants to the sludge load of coal mine water turbidity, within a certain amount of mud, the sludge load of coal mine water turbidity expands with the increase of the concentration value of Polymeric Aluminium Chloride and Polyacrylamide. The mutual application of Polymeric Aluminium Chloride and flocculant has a significantly better effect on the removal of turbidity than when they are applied independently, and the dosage is also significantly reduced. It is because Polymeric Aluminium Chloride is a kind of inorganic polymer material electrolyte solution, in the whole process of slant plate sedimentation tank, the key effect is to reduce the floating particles of the surface potential difference, and then weaken the particles asked the anisotropic phase attraction, promote the particles in the whole process of impact agglomeration. Although polymerized aluminum chloride presents high value convergent positive ions immediately after the hydrolysis reaction, the cohesive force and the effect of bridging chain are still relatively weak. Flocculant is a kind of Organic Polymer Coagulant, this kind of linear polymer material coagulant has the effect of bridge chain, which can turn the particle cohesion group into the slant plate sedimentation tank body with enough foundation to settle.

Background and Overview In recent years, with the continuous development of China's petrochemical industry, the production capacity of ethylene grows year by year, which brings a broad space for the development of China's C5 Petroleum Resin.C5 petroleum resin is made by polymerizing the C5 fraction, which is a by-product of ethylene plant, as the main raw material in the presence of catalyst. The resin is inexpensive and has excellent properties such as acid resistance, alkali resistance, anti-aging, weather resistance, etc. It is widely used in coatings, inks, seals, adhesives and so on. Structure of C5 Petroleum Resin The main chemical structure of C5 petroleum resin is shown in the figure: C5 petroleum resin is a kind of low relative molecular mass thermoplastic resin, generally the average relative molecular mass is between 1000~3000, the resin is yellow to light brown, it has good performance of lowering coagulation and increasing viscosity and improving viscosity coefficient, it is soluble in solvents such as benzene, toluene, xylene and so on, and it can be mixed and dissolved with EVA (Ethylene-Vinyl Acetate Copolymer), polyethylene and so on. As C5 petroleum resin belongs to non-crystalline substances, there is no certain material and petroleum resin research. Melting point, usually using the globe method to determine its softening point. Softening point is the most important property of C5 petroleum resin, which marks the hardness, brittleness and viscosity of petroleum resin. At present, the C5 petroleum resin produced in China can be divided into two series of 80~110℃ and 110~160℃ according to the softening point. Application of C5 petroleum resin 1. Tackifier C5 petroleum resins are used in adhesives for structural and decorative purposes in the construction industry, automobile assembly, tires, wood processing, commodity packaging, bookbinding, sanitary products, footwear industry, etc. C5 petroleum resins are the tackifying component of many adhesives, e.g., hot-melt adhesives, pressure-sensitive adhesives. 2. Additives As an Additive of paint, petroleum resin can speed up the drying speed of paint film, improve water resistance, acid and alkali resistance, surface hardness and gloss, road marking paint containing 10%~30% hydrogenated petroleum resin has enough durability, good thermal stability and weather resistance. Add C5 petroleum resin in rubber (dosage of about 15%) can play a softening, viscosity and so on, can improve the processing performance of rubber, foreign countries have been in styrene-butadiene rubber, butadiene rubber, halobutyl rubber and other synthetic rubbers in the use of C5 petroleum resin. Petroleum resins can be used as the main additives of asphalt materials for housing construction, sealing, coating and flood control construction, especially suitable for laying colored pavement. In order to solve the separate use of polypropylene or polybutylene as medical containers and packaging materials (such as blood bags, liquid drug bags, infusion tubes, etc.) when the existence of poor heat resistance, poor transparency and softness and other issues, can be hydrogenated petroleum resin as an additive. 3. Petroleum Resin for paper making Petroleum resins formulated into emulsions can be used as sizing agents in the paper industry, thus expanding the application areas of finished resins. As the petroleum resin is a non-polar substance, can not be boiled directly into sizing emulsion, must be petroleum resin with active groups of maleic anhydride, rosin and other mixed use. China's development and application of petroleum resin for papermaking started late. Shanxi Institute of Applied Chemistry synthesized several varieties of petroleum resins for papermaking by hot polymerization method, and carried out a lot of experimental work on its sizing performance.

Rubber accelerator is a commonly used additive in the rubber industry, which can significantly increase the strength and abrasion resistance of rubber products, improve the processing performance and weather resistance of rubber. The correct use of rubber accelerators can give rubber products better performance, extend service life, reduce costs and increase productivity. First of all, the right formulation is the key to using rubber accelerator to improve the strength of rubber products. Adding appropriate amount of rubber accelerator into the formula of rubber products and making good cooperation with other additives such as vulcanizing agent, chain extender, etc. can get better results. Usually we can determine the amount of rubber accelerator according to the type of rubber, use and performance requirements and other factors. Secondly, the correct control of mixing conditions during the rubber mixing process is also an important step to improve the strength of rubber products. Rubber accelerator is usually added together with the rubber in the mixing process, so it is necessary to ensure that the mixing temperature, time, shear force and other parameters of the control, in order to give full play to the role of rubber accelerator. At the same time, attention should also be paid to phenomena such as rubber breakage and carbon burning during the mixing process to avoid affecting the quality of Rubber Products. Then, the correct choice of suitable vulcanization process is also the key to improve the strength of rubber products. Rubber in the vulcanization process, rubber accelerator through the reaction with the vulcanizing agent, the formation of crosslinked structure, thereby improving the strength of rubber products. Therefore, in the vulcanization process, attention should be paid to the vulcanization temperature, vulcanization time, vulcanizing agent type and content and other parameters of the choice, in order to ensure that the rubber accelerator M can give full play to its role in improving the strength of rubber products. In general, the correct use of Rubber Auxiliaries to improve the strength of rubber products need to take into account the formulation design, mixing conditions and vulcanization process and other factors, and should be adjusted and optimized according to specific circumstances. Only by trying and summarizing experience in practice, can we better play the role of rubber accelerator and improve the performance and quality of rubber products.

Rubber is an elastic material made of natural or synthetic polymer materials.

About the selection of inorganic Flocculants, most of them should be selected according to the water quality of the symptoms, in fact, it is very simple, as long as we remember a few points can be. 1. Industrial sewage, wastewater, municipal wastewater are generally selected industrial grade Polymeric Aluminium Chloride, the content is divided into 26-28%, usually wastewater treatment are used 26% content, municipal wastewater is recommended to use 28% content, the amount of sludge produced will be relatively small. 2. Choose 28%-30% Polymeric Aluminium Chloride for water reuse. 3. Drinking water, tap water, industrial water, raw water of power plant, industrial circulating water, etc. are chosen to use 30% content, 30% content of Polymeric Aluminium Chloride is the implementation of the national drinking water level standard. The reason why it is used in industrial water, raw water of power plant and industrial circulating water is that it produces less sludge and has higher processing efficiency. 4. For domestic sewage or sewage with high phosphorus content but good biochemical properties, choose aluminum sulfate, the advantage of Aluminium Sulfate is that the cost is lower compared with other flocculant products, and the phosphorus removal rate is higher. Disadvantage The disadvantage is that the flocculation and precipitation effect is almost the same as the effect of polymerized aluminum gasification, so the premise of choosing aluminum sulfate is that the requirement of biochemistry is high, otherwise the flocs will be very difficult to settle. 5. Machining or cutting fluid wastewater in some cases will contain a small amount of oil floating on the surface of the waste oil, diesel oil, etc., this wastewater selection of aluminum sulfate, Aluminium Sulfate can remove the water surface oil and grease, to play the role of emulsion breaking. to emulsion breaking effect. Aluminum sulfate can also be used as ink wastewater flocculation oil decolorization. (Note: only as the removal of surface floating oil and grease, suspended in the water or mixed with the water or emulsion of oil and grease with aluminum sulfate can not be removed) 6. Raw water of power plant, papermaking sewage, industrial sewage, etc. can choose polymeric ferric sulfate. 7. Fenton reagent, printing and dyeing, leather, electroplating and other sewage containing heavy metals, chromaticity, COD higher choice of ferrous sulfate. The advantage of ferrous sulfate is low cost, the disadvantage is that the sludge produced The disadvantage is that it produces sludge. 8. Alkaline aluminum chloride is usually used as flocculation and precipitation in industrial sewage such as ink, leather, printing and dyeing, etc. The treatment cost is low, the disadvantage is that the salinity is high, and the dosage will become large in low temperature environment, which is suitable for indoor water treatment process in the southern region or more constant temperature. 9. Swimming pools, well water, reservoir water and other water treatment options for spray-dried polymerized aluminum chloride, spray dry polymerized aluminum chloride salinity is lower, usually for lower turbidity water. 10. Pure white polymeric aluminum chloride can be used as paper sizing agent, cosmetic additives, food preservatives, etc., relatively few applications in the water treatment industry, generally used in water treatment as reverse osmosis or pure water, mineral water and other water treatment.

1. The use of domestic sewage In domestic sewage treatment, polyacrylamide by means of electrical neutralization and its own adsorption and bridging effect, can promote the suspension of turbid particles rapid agglomeration and sedimentation to achieve separation, clarification of the role. Mainly used in the sewage treatment plant in the first part of flocculation and sedimentation and the latter part of sludge dewatering. 2. Usage in industrial wastewater When adding polyacrylamide in the water of suspended turbid particles, it can promote the rapid coagulation and sedimentation of suspended turbid particles to achieve separation and clarification to improve the operation efficiency and reduce the cost of use by the neutralization of electrical properties and the adsorption and bridging effect of macromolecule itself. 3. The use of textile printing and dyeing industry water treatment Polyacrylamide as a fabric post-treatment sizing agent, finishing agent, can generate smooth, anti-wrinkle, mold-resistant protective layer. Utilizing its strong hygroscopicity, it can reduce the rate of thread breakage when spinning fine yarns; it can also prevent the fabric from static electricity and resistance. When used as printing and dyeing auxiliaries, it can make the product adhesion fastness enhancement, vividness increase; it can also be used as a non-silicon polymer stabilizer for bleaching; in addition, it can be used for textile printing and dyeing sewage purification. 4. Use in steel mill wastewater treatment Mainly oxygen top blowing converter flue gas purification wastewater, usually called converter dedusting wastewater. Steel plant converter dedusting wastewater treatment should focus on solving the management of suspended solids, temperature balance and water quality stabilization. The coagulation and precipitation treatment of suspended matter needs to remove large particles of suspended impurities, and then enter the sedimentation tank. In the open ditch of the sedimentation tank, PH adjusting agent is put in, and polyacrylamide is put in, so as to realize the co-flocculation and precipitation of suspended matter and scale-forming matter in the sedimentation tank, and then, scale inhibitor is put in the effluent water of the sedimentation tank. 5. Usage in chemical plant sewage treatment The chromaticity and pollutant content of wastewater is high, mainly due to the insufficient reaction of raw materials or the production of a large number of solvent media used in the wastewater system generated by the biological difficult to degrade substances, poor biochemistry, toxic and hazardous substances, the water quality is complex, the reaction of raw materials are often solvent substances or compounds of cyclic structure, which increases the difficulty of treatment of wastewater; selection of the applicable type of polyacrylamide can achieve a better processing Selection of suitable polyacrylamide model can achieve better treatment performance. 6. Usage in alcohol plant wastewater treatment How is polyacrylamide applied? In general, polyacrylamide is mainly used in the post-throwing sludge dewatering process, generally choose cationic polyacrylamide in this case, what kind of ionic degree cationic polyacrylamide and what kind of raw materials are used in the production of alcohol? What kind of wastewater treatment process? As well as the PH value of the sludge, the specific circumstances generally recommended to do laboratory beaker experiment selection. 7. Use in brewery wastewater treatment Treatment is generally used aerobic treatment technology, such as activated sludge, high load biological filtration and contact oxidation method. From the current case can be understood that the general brewery flocculants generally use strong cationic polyacrylamide, molecular weight requirements of more than 9 million efficacy is more prominent, the dosage is more economical, the cost is also relatively low, after the filter press out of the mud cake water content is relatively low. 8. Use in food wastewater treatment The traditional method is physical sedimentation and biochemical fermentation, in the biochemical treatment process to use polymer flocculants, do sludge dewatering. Polymer flocculants used in this treatment are generally cationic polyacrylamide products with relatively high ionicity and molecular weight. In the selection of polyacrylamide products should pay attention to the following aspects: climate change (temperature) affects the flocculant wash type, the molecular weight of the flocculant, flocculant charge value. 9. The use of water treatment in the field of papermaking Polyacrylamide is widely used as retention aid, filtration aid, dispersant and so on in papermaking field. Its role is to be able to improve the quality of paper, improve the performance of pulp dehydration, improve the retention rate of fine fibers and fillers, reduce the consumption of raw materials and pollution of the environment. Anionic copolymers are mainly used as wet and dry enhancers and retention agents for paper; cationic copolymers are mainly used in papermaking wastewater treatment and filtration aids, and also have a good effect on improving the retention rate of fillers.

Polyvinyl Alcohol (PVA) is one of the most versatile water-soluble Polymers, PVA can be quickly dissolved in water to form a stable colloid, performance between Plastics And Products.Polyvinyl Alcohol Fiber is one of the important varieties of synthetic fibers, and its regular product is polyvinyl alcohol formaldehyde fiber, which is referred to as vinylon or Vinylon in China. The products are mainly short fibers. Polyvinyl Alcohol Fiber is mainly used for blending with cotton, woven into a variety of cotton fabrics. In addition, it can also be blended with other fibers or pure spinning, weaving all kinds of woven or knitted fabrics. The performance and appearance of polyvinyl alcohol filament is very similar to that of natural silkworms, and it can be used to weave satin fabrics. However, because of its poor elasticity, it is not easy to dye, so it can not be made of high-level clothing. In recent years, with the development of polyvinyl alcohol fiber production technology, its application in industry, agriculture, fishery, transportation and so on is expanding. Ordinary polyvinyl alcohol has a high degree of polymerization and alcoholysis, in the flexible main chain contains a large number of hydroxyl, intermolecular and intramolecular formation of a large number of hydrogen bonds, physical crosslinking points, high density, resulting in polyvinyl alcohol fibers with high crystallinity, is not conducive to the penetration of water molecules. If you improve the water solubility must weaken the affinity between the macromolecules, there are two general methods: reduce the hydroxyl content and increase the distance between the hydroxyl group. Polyvinyl alcohol with the increase in degree of polymerization, fiber hydrophobicity increases, the water solubility temperature increases accordingly. Therefore, the use of low polymerization degree of polyvinyl alcohol for spinning, can get a lower water soluble temperature of the fiber. However, the polymerization degree decreases, the spinnability becomes worse. Japanese patents use low polymerization degree (less than 800) components and high polymerization degree (more than 1000) components for co-spinning, the resulting fiber spinning and water solubility are ideal. The degree of alcoholysis of polyvinyl alcohol also has a great influence on the water solubility of fibers. The residual ethylcool group will hinder the close arrangement of macromolecules, so that the crystallinity will be poor, and the water solubility temperature will be lowered. However, the presence of residual ethylcool group will affect the tensile properties of primary fibers and increase the number of broken filaments and hairy filaments, and will also affect the coloring of fibers, so the degree of alcoholysis of water-soluble polyvinyl alcohol should be an appropriate level.

Rubber accelerator is a commonly used processing aid, mainly used in the production process of rubber products to improve the processing performance and performance stability of rubber. However, not all rubber products are suitable for the use of rubber accelerators. Firstly, rubber accelerator is suitable for use in natural rubber and some synthetic rubbers, such as styrene-butadiene rubber, nitrile rubber, granular polyvinyl chloride rubber and so on. However, for some special rubber types, due to the differences in their structure and properties, rubber accelerators may not be suitable and may even have a negative impact on their performance. Therefore, when selecting a rubber accelerator, it is necessary to select it according to the specific rubber type and experimentally verify its suitability. Secondly, even if a rubber product is suitable for the use of rubber accelerators, it is necessary to determine whether or not to use them according to the specific requirements of the product. Different rubber accelerators have different properties and may have different effects on the performance of the product. Rubber accelerators are mainly used to improve the processing performance and performance stability of rubber, which can make the rubber flow and mould release easier during processing, and improve the heat resistance and ageing resistance of the products. However, for some products, such as special-purpose rubber products or products requiring other performance needs, it may be necessary to select other specific accelerators. In addition, the amount of rubber accelerator to be used needs to be determined according to the specific product requirements. Too high or too low an amount may have a negative effect on the performance of the product. Too high a dosage may result in a decrease in the hardness, strength and other properties of the rubber product, while too low a dosage may make the processing of the rubber difficult or even impossible to meet the requirements of the product. Therefore, when using rubber accelerators, it is necessary to determine the appropriate amount of use according to the specific product requirements and test results. In conclusion, rubber accelerator is not suitable for all rubber products. When selecting rubber accelerator, it is necessary to consider the type of rubber, product requirements and the amount of use and other factors, and through the experiments to verify its suitability. At the same time, it is also necessary to pay attention to the amount of rubber accelerator to ensure that the products can meet the corresponding performance requirements.
