Asiafloc series products have wide range of applications

Polyacrylamide (PAM) is a water-soluble linear polymer formed by the polymerization of acrylamide (AM) monomer initiated by free radicals. According to ionic properties can be divided into anionic polyacrylamide, cationic polyacrylamide, non-ionic polyacrylamide, amphoteric polyacrylamide four types.

 Polyacrylamide properties

 (1) flocculation: polyacrylamide can make suspended matter through the point and bridge adsorption, flocculation.

 (2) adhesion: it can play a bonding role through mechanical, physical and chemical effects.

 (3) resistance reduction: polyacrylamide can effectively reduce the friction resistance of the fluid, adding a trace of PAM in water can reduce the resistance of 50-80%.

 (4) thickening: PAM has thickening effect under both neutral and acidic conditions. When the PH value of PAM is above 10, it is easy to hydrolyze and form a semi-network structure, the thickening will be more obvious.

 Polyacrylamide uses:

 (1) Municipal sewage

 In the treatment of domestic sewage, polyacrylamide can promote the suspended particles of rapid agglutination settlement to get the result of separation, clarification by the electrical neutralization and its own adsorption bridge function,It is mainly used in the front section flocculation settling and the back section sludge dewatering of sewage treatment plant.we strongly recommend our cationic polyacrylamide series with low and medium chagre.Asiafloc C80510, Asiafloc C81012,Asiafloc C82012 is the advanced models for this application.

 (2) Industrial wastewater

 When polyacrylamide is added to the suspended turbidity particles in the water, by means of the neutralization of the electrical property and the adsorption bridge function of the polymer itself, the suspended turbidity particles can be rapidly coagulated and settled, and the effect of separation and clarification can be achieved, so as to improve the operation efficiency and reduce the operation cost.we recommend our models of ASIAFLOC A73018 and ASIAFLOC A72015.

 (3) Textile printing and dyeing industry

 As a sizing agent and finishing agent for fabric post-treatment, polyacrylamide can produce a protective layer that is supple, wrinkl-resistant and mildew resistant. With its strong hygroscopicity, the breakage rate of spinning yarn can be reduced. It can also prevent static electricity and flame retardant of the fabric. When used as a printing and dyeing auxiliaries, it can enhance the adhesion fastness and heighten the brightness of the products. It can also be used as a non-silicon polymer stabilizer for bleaching; In addition, it can also be used for efficient purification of textile printing and dyeing sewage.our cationic and anionic polyacrylamide have good performance for this application.

 (4) Paper industry

 Polyacrylamide is widely used as retention aid, filter aid and dispersant in the field of paper making. Its function is to improve the quality of paper, improve the dehydration performance of pulp, improve the retention rate of fine fiber and filler, reduce the consumption of raw materials and environmental pollution. The effect of its use in papermaking depends on its average molecular weight, ionic properties, ionic strength and the activity of other copolymers. Non-ionic PAM is mainly used to improve the filtering property of pulp, increase the strength of dry paper, and improve the retention rate of fiber and filler. Anionic copolymers are mainly used as dry and wet reinforcing agents and resident agents for paper. Cationic copolymer is mainly used in papermaking wastewater treatment and filtration aid, and it also has a good effect on improving the retention rate of filler. In addition, PAM is also used in papermaking wastewater treatment and fiber recovery.

 (5) Coal industry

 Coal washing wastewater, coal preparation plant of slurry, the ground of the coal-fired power plant washing wastewater is a mixture of water and fine coal, its main characteristic is high turbidity, solid particle size, solid particle surface more negatively charged, same-sex repulsion between the charge to keep these particles in the water dispersion state, is affected by gravity and Brownian motion. Because of the interaction between the solid particles in the coal slime water, the properties of the coal washing wastewater are quite complex, which not only has the properties of suspension, but also has the properties of colloid. In order to make the slime water precipitate quickly in the thickening pool, ensure qualified washing water and pressure filtration slime production, and make the production run efficiently and economically, it is necessary to choose appropriate flocculant to strengthen the treatment of slime water. A series of polymer flocculating dehydrants developed for coal slime dehydration in coal washing plant have high dewatering efficiency and simple operation.we recommend our models of ASIAFLOC A72520 and ASIAFLOC A72015.

 (6) Alcohol industry

 How is polyacrylamide applied? In general, polyacrylamide is mainly used in the sludge dewatering process after the section, generally this case choose cationic polyacrylamide, choose what kind of ionic cationic polyacrylamide and ethanol production of raw materials? What kind of wastewater treatment process? And the PH value of sludge, the specific situation is generally recommended to do laboratory beaker experiment selection.we recommend our models of ASIAFLOC A73018 and ASIAFLOC A73016

 (7) Electronics and electroplating industry

 The commonly used treatment process in the first reaction pool first with sulfuric acid to adjust the pH value of wastewater to 2 ~ 3, then add reducing agent, in the next reaction pool with NaOH or Ca(OH)2 to adjust the pH value to 7 ~ 8, the formation of Cr(OH)3 precipitate, and then add coagulant, so that Cr(OH)3 precipitate to remove.our advanced model ASIAFLOC A73018 can meet this application.

 (8) Steel mills

 The waste water is mainly purified by oxygen top blown converter flue gas, usually called converter dust removal waste water. The treatment of converter dedusting wastewater should focus on the smelting of suspended solids, the balance of temperature and the stability of water quality. The coagulation and precipitation treatment of suspended matter should remove the large suspended impurities, and then enter the sedimentation tank. Add PH regulator in the open ditch of the sedimentation tank, and add polyacrylamide, so that in the sedimentation tank to achieve the common flocculation and precipitation of suspended matter and scale, and then add scale inhibitor in the water of the sedimentation tank. In this way, it not only solves the problem of clarification of wastewater, but also solves the problem of water stability, so as to achieve a better treatment effect. Polyaluminum chloride (PAC) was added into the sewage, and the polymer flocculated the suspended matter in the water into small floc; When the polyacrylamide PAM is added to the sewage, it becomes a bigger flocs with strong binding force and precipitates down through a variety of bonds. The combination of PAC and PAM is more effective through practice.we recommend the models of Asiafloc A73016 and ASIAFLOC A73018

 (9) Chemical plants

 The shade of the sewage and pollutant content is higher, the main raw materials was not complete or used in the production of a large number of solvent medium into the wastewater system, produced by the refractory materials, biological sex difference, the poisonous, harmful water composition is complicated, reaction solvent for raw materials often substances or ring structures of compounds, increasing the difficulty of wastewater treatment. Selecting suitable polyacrylamide model can achieve better treatment effect.ASIAFLOC A73018 and ASIAFLOC A72520 is advanced models for this application.

 (10) Cigarette factory

 In the period of sludge dewatering, polyacrylamide flocculant selection more difficult, change range of water quality is bigger, related technical personnel should pay attention to the change of water quality and sludge dehydrating test selection, the workload is relatively large, generally choose the cationic polyacrylamide, the requirements of the molecular weight is higher, medicament reaction speed of applicability will be better in the requirements of the equipment.

 (11) Brewery

 The treatment generally adopts aerobic treatment technology, such as activated sludge method, high-load biological filtration method and contact oxidation method. From the current case can understand that the general brewery use of flocculant generally use strong cationic polyacrylamide, molecular weight requirements of more than 9 million effect is more prominent, the dosage is relatively provincial, the cost is relatively low, after the filter press out of the mud cake moisture content is relatively low.our cationic series can meet this application totally.
