[Zhengzhou polyacrylamide manufacturer, polyacrylamide price, polyacrylamide wholesalers, polyacrylamide, use of polyacrylamide flocculant] 15038352687 [] Eight applications introduce my factory production of polyacrylamide flocculant cheap! 1, [oil] polyacrylamide flocculant since 1964 Pa according to (rye) and Sandiford proposed raw water after the addition of a small amount of PAM can reduce the flow of water, this method has been applied in the oil field 40 years of history. So that PAM and formaldehyde, sodium hydrogen sulfite solution. The reaction can be generated with the sulfomethylated product at the appropriate temperature. Experimental results show that the introduction of salt in the PAM chain can improve the thermal stability, shear resistance and low absorption, the polymer of hydrophilic and salt resistance greatly improved, and improved resistance to high ionic contamination of the product capacity. PAM as a multifunctional additive. By the swap used in the drilling process, mud, flocculation and sedimentation stabilizer system to improve the rheology of slurry; can improve the size of the suspended particles, increase suspension force, to accelerate oil filtration, separation. As soil structure forming agent, so that the wall surface to improve impact resistance, so that the slurry is not easy to obtain an efficient dispersion of the separation layer when drilling through the start. So were partially hydrolyzed polyacrylamide flocculant with formaldehyde, glyoxal occur hydroxymethyl side chain reaction to produce a product containing methyl, satisfactory results can be obtained in crude oil production. When secondary recovery will PAM injected brine, brine injection can increase the capacity, from porous rock surface effectively crude oil extraction down. - Oil in water emulsion added PAM, can significantly reduce the viscosity of the emulsion. Added oil storage tanks, can reduce the moisture content of the oil pool surface and reduce the use of cost. In oil, the increase of the viscosity of water injection to avoid breakdown oil, enhanced oil recovery. Used as a thickener in the third oil recovery, increase flooding capacity, improve oil bed mining results. In the field of oil, the updated anions and cations of PAM can be used to protect groundwater from start injection hole penetration and oil agglomeration recovery and improve the economics of production wells, control of water to the reservoir incorporation. In addition. PAM is also used for the fracturing fluid additives, lubricants, reduction agent and the like. In oilfield chemistry, PAM is versatile additives such as drilling fluids, flushing fluid, water and improve oil recovery and so plays an important role. Use PAM linear macromolecular structure, it is likely to be oriented according to the direction of flow lines like growth under turbulent state, suppression of turbulence development. PAM can be used as an ideal material for reducing friction agent, and in long-distance pipeline transportation of crude oil, the added 0.lmg / L (crude oil volume) PAM, can greatly reduce the crude oil resistance, thereby reducing energy consumption. 2, [paper] PAM polyacrylamide flocculant in papermaking applications, began anionic PAM 40 years ago. Followed by the rapid development of all kinds of modified PAM, especially AM with other monomers and graft copolymer and starch-based AM. Additives used in papermaking, the amount of overseas quite large. Different molecular weight PAM also has its own different purposes: molecular weight (M) 1000 ~ 10000 for dispersing agent, can improve the uniformity of the sheet when possible; M is 500,000 to 1,000,000 can be used as a reinforcing agent, can effectively improve the strength of paper; M 1,000,000 to 2,500,000 can be used as retention agents, drainage agents, suspending agents, fillers, and retention rates can increase fines, to accelerate the dehydration speed, but also settled sewage, reducing the amount they lost in the water. PAM can be used as paper mill effluent treatment agent. Treated wastewater can be recycled, and strictly control the water content of metal ions. 3, [] polyacrylamide flocculant for water treatment in industrial water and wastewater treatment, we must first deal with the raw water. Often used PAM and inorganic coagulant complex, thereby greatly reducing the amount of inorganic coagulant, avoid large amount of inorganic aggregates clogging and corrosion of equipment, and to prevent fouling. 37.5 parts of the polymer using PAM with 50 parts sodium tripolyphosphate composition inhibitors. Can severely fouling heat exchanger is basically not fouled. PAM flocculating agent after as a modified starch with modified to increase the binding capacity of water, which is prepared with 85 parts of starch, 15 parts of PAM. Such as making potato starch 100kg 150t suspended in water (55 ℃), with Na2CO3 0.5kg, NaOH 0.3k mixed and stirred at 50 ℃ 2h, then the starch is filtered off, washed with water. Adjusting pH to 6.5, and then filtered and dried. Finally reaction with PAM 20kg formed. PAM polymer flocculants can be used as a handle milky pulp wastewater suspended solids, and water becomes colorless liquid, suspended solids concentration to 50mg / L or less. PAM intramolecular amide group of affinity with many substances to form hydrogen bonds. PAM polymer is a functional group capable of adsorbing particle linear polymers. It is like a long rope, like some of the particles together to form a floc adsorption, also can accelerate particles to settle. "Bridged" PAM can be formed between the polymer particles are adsorbed from its long carbon chain bridging role, by chemical conversion or copolymer containing into male and female, complete flocculant system nonionic and zwitterionic, promote Mission floc formation, accelerate the fallout. Thus making it the most important contemporary, the best flocculant is in the amount of one of the largest polymer flocculant. Compared with other flocculant PAM, its variety, complete specifications. To meet the different requirements for wastewater treatment. It with less. Man sedimentation rate, less sludge is generated after simple processing. PAM for industrial sewage. Sugar industry waste water and wastewater treatment chemicals, oil exploration, metallurgy, coal and other industries. Wastewater can strengthen rapidly achieve solid-liquid separation. Removal of most small mechanical impurities, to purify sewage purposes. For example, for the sugar industry, it can precipitate 20 times faster. Its molecular weight greater. Flocculation, the better, the general amount of 1 ~ 15mg / L. 4, [polyacrylamide flocculant Soil and Water Conservation] 20 years ago, the United States has successfully used PAM soil structure forming agent. Applying a small amount of PAM copolymer, can significantly improve the ability of anti-wind and water erosion of soil, more effective than traditional enhancers (such as asphalt), etc. PAM has a water-soluble powder, when rainfall can spread evenly with water and penetrate into the soil pore saturated. Since PAM flocculation resistance, encountered soil particles suspended in the water when a plurality of components may be adsorbed to soil particles, soil particles and a plurality of components can also be adsorbed molecules, resulting in a large group of coagulation. These coagulation group, reducing the raindrops on the soil surface splash erosion force, and the role of molecules is reduced from the power of the particles. Sticky molecules also reduced fluid resistance, increased corrosion resistance and strengthen the interaction between soil particles, so that the soil and stable table. Water retention, soil conservation, fertilizer effect is very obvious, to play an active role in soil erosion. Since PAM degree of hydrolysis (HPAM) of soil aggregate can improve air circulation, water permeability and water retention, in addition to as a soil amendment, soil and water conservation agent, but also can be used for plugging agent, antifreeze and water fruit trees Respiratory resin. 5, carbon fiber-reinforced resin [flocculant polyacrylamide flocculant] carbon fiber reinforced resin is a synthetic resin polyacrylamide flocculant polyacrylamide resin matrix, adding a variety of fiber-reinforced polymer composites made. Carbon fiber reinforced plastic composite materials in future applications will dominate. 6, [textile] flocculant polyacrylamide PAM in the textile industry can be used for sizing agents, finishing agents. Use acrylamide copolymer substitute for gelatin and starch fiber slurry. Carding the fibers can have excellent properties, and significantly reduce the consumption of the slurry. 7, flotation separation [] PAM polyacrylamide flocculant flocculant as efficient as other flocculant less. Join HPAM in mineral suspension, and under ultrasonic irradiation produces efficient flocculation. It was used for coal flotation can accelerate deposition of aggregation for coal may increase recovery rates and reduce energy consumption. Use in hematite-quartz mixture HPAM with selective flocculation using between HPAM polymer molecules with hematite powder surface strong intermolecular binding force, separable quartz powder. The HPAM for the selective separation has caused great interest of researchers, we are looking for the optimum conditions to achieve significant results. 1976 Japanese scholars after use containing Ti (OH) 4 massive PAM crushed, had proposed uranium metal from seawater. 1979 using the Fe (OH) 2, En (OH) 2 or the like PAM copolymer adsorption Ca, Ni, Cu and other metals from the success. 1983 China Taiwan synthesis of a zirconium phosphate PAM resin, which effectively separated Cs, Co, Ce other metal ions. 1988 Japan and then synthesize a tin phosphate PAM resin for extracting metal ions PAM flocculant polyacrylamide flocculant for water resources in water treatment technology is now getting worse social Water Resources and Environment from the sea. A lot of nitrogen and phosphorus in water seriously overweight, smelly water, forming eutrophication. Our company specializes in the production of water treatment chemicals, the company has a variety of water Eutrophication causes of a field of study and research, the results obtained show that eutrophication caused by nitrogen and phosphorus and other nutrients mainly from: flocculant polyacrylamide molecular weight, degree of hydrolysis, ionic, viscosity, residual monomer content and other technical indicators tell. ① high molecular weight polyacrylamide flocculant PAM molecular weight, and in recent years there is a large increase. 1970 applications PAM, millions of molecular weight generally; 80 years later, most efficient PAM molecular weight of more than 15 million, some 20 million. Each of these PAM molecule is polymerized from more than 100,000 acrylamide or sodium acrylate molecule made (molecular weight acrylamide is 71, the molecular weight of a monomer containing thousands of PAM of 7.1 million). Typically, preferred high molecular weight PAM flocculation, the molecular weight of acrylamide is 71, the molecular weight of a monomer containing thousands of PAM of 7.1 million. Molecular weight polyacrylamide flocculant and its derivatives from several hundred thousand to more than ten million, according to the molecular weight can be divided into low molecular weight (below 100 million), the molecular weight (100 million to 10 million), a high molecular weight (10 million ~ 15 million), ultra-molecular weight (over 15 million). The molecular weight of the organic polymer, even within the same product is not entirely uniform, its nominal average molecular weight. ② degree of hydrolysis of polyacrylamide flocculant ion degree ion of PAM of its effect has great influence, but its value is subject to appropriate type and nature of the material being processed may be, under different circumstances will be different optimum value. If the ionic strength of the treated material was higher (containing more inorganic), the use of PAM the plasma should be higher, and vice versa should be low. Typically, the anion is called the degree of hydrolysis degree. The ions of the general specific cation. Polyacrylamide flocculant ion degree = n / (m + n) * 100% PAM early production by polymerization of acrylamide monomer from the original without -COONa groups. First increase before using NaOH heated to partially hydrolyzed -CONH2 group -COONa, reaction is as follows: -CONH2 + NaOH - → -COONa + NH3 ↑ polyacrylamide flocculant hydrolysis of ammonia in the process of evolution. PAM proportion of amide groups hydrolyzed PAM is called the degree of hydrolysis, which namely is an anion degrees. This PAM is inconvenient to use, and poor performance (thermal hydrolysis will cause PAM molecular weight and performance degradation), has been rarely used after the 1980s. Modern production anionic PAM there are many different degrees of products, users can later be used in accordance with actual needs and the selection of appropriate test species, does not require re-hydrolyzed and dissolved. However, because of habit, some people will flocculant dissolution process is called hydrolysis. It should be noted that the meaning of hydrolysis is hydrolyzed, is a chemical reaction, hydrolysis release ammonia PAM there; dissolved merely physical action, without chemical reaction. Essentially different should not be confused. ③ residual monomer content of residual monomer content polyacrylamide flocculant PAM is defined as the polymerization of acrylamide in polyacrylamide flocculant process, the unreacted residue in full and final products of polyacrylamide flocculant acrylamide monomer content, is an important parameter to measure whether or not suitable for the food industry. Polyacrylamide flocculant is non-toxic, but has some toxicity of acrylamide. Polyacrylamide flocculant in industrial products, it is inevitable there are traces of residual acrylamide monomer polymerization. Therefore, we must strictly control the PAM product residual monomer content. International regulations for drinking water and food industry PAM residual monomer content of not more than 0.05%. The value of foreign well-known product of less than 0.03%. ④ polyacrylamide flocculant PAM solution viscosity is very viscous. PAM molecular weights higher solution viscosity greater. This is because the PAM molecular chain is long and thin body, in the solution of the great resistance movement. The essence is reflected in the viscosity of the solution frictional force magnitude, also known as the coefficient of friction. The viscosity of various polymer organic solution are high, and with the molecular weight increases. A method for determining the molecular weight of the organic polymer, a certain concentration of the solution is measured under conditions of viscosity, then a certain formula to calculate the molecular weight, known as the "viscosity average molecular weight." 1. Although not treated or treated but non-compliance of nitrogen and phosphorus in the effluent discharged into rivers and eventually into the lake; 2. agricultural fertilizer runoff problems. Tanaka has not been absorbed by a large number of crops nitrogen, phosphorus into the river along with the water, resulting in excessive nitrogen and phosphorus; 3. towns and villages scattered on both sides of the river system, a lot of life in rural water directly discharged into rivers. The first question may increase the intensity of governance, strive to make the municipal wastewater treatment plant effluent nitrogen and phosphorus emissions are up to par, it is necessary to use flocculant polyacrylamide flocculant, but farm fertilizer runoff problems and villages, sewage in rural areas impossible to concentrate on building pipe network, centralized treatment. How to deal with the problem of fertilizer runoff and river towns on both sides, rural sewage discharge farmland is the key to solve the problem of eutrophication of rivers and lakes. However, after the above-mentioned three lakes of sewage to be discharged into rivers or into the Main River, it is targeted to enter the lake or the main tributaries of the river governance, ensure access to the main lakes and rivers of the river water quality compliance, no further pollution mainstream lake , thereby cutting off the main lake river pollution source. Flocculant polyacrylamide flocculant same liquids and solids do? PAM source of water purification flocculant polyacrylamide PAM PAM with excellent selectivity and adaptability, is to obtain the rapid development of high-tech chemical products in the world today, Widely used in oil field water by the swap, low solids non-dispersed drilling mud flocculants, soil conditioners, textiles and pulp, paper reinforcing agents, soil stabilizers, fiber paste, resin processing aids, dispersants, and for help Shen, coal washing, sewage treatment, uranium leaching, oil drilling and the like. PAM as a new polymer material, its application and development progress quickly. We have achieved remarkable results.
