Introduction of polyacrylamide
Polyacrylamide (PAM) is divided into anionic polyacrylamide, cationic polyacrylamide. Amphoteric ionic polyacrylamide, non ionic polyacrylamide. It is a kind of water-soluble linear polymer which is polymerized by monomer acrylamide. The appearance of the product is white powder, soluble in water, almost insoluble in benzene, ether, ester, acetone and other general organic solvents, its aqueous solution is nearly transparent viscous liquid, is non-dangerous, non-toxic, non-corrosive, solid PAM has hygroscopicity, The hygroscopicity increases with the increase of ionic degree.
Screening of Polyacrylamide
Purpose of screening: to remove small particles from granulation products to ensure that they look good and meet the requirements of finished products!
-because of this property, it is often used as a purifying agent to flocculate impurities in the treatment of water and thus to purify them.
-this property is also one of the raw materials for paper, products, and petroleum auxiliaries.
- the characteristics of water in the water.
-the characteristics of thickening and adhesion.
Application of anionic polyacrylamide
1 . Mainly used as flocculating agent : for suspended particles , coarse , high concentration , positive charge of particles , PH value of water as neutral or alkaline waste water , because the anionic polyacrylamide molecular chain contains a certain amount of polar group capable of absorbing suspended solid particles in water , it can accelerate the settling of the solution , promote filtration and the like . The product is widely used in the treatment of chemical industrial waste water , waste liquid , municipal sewage treatment , tap water industry , high turbidity water purification , settling , coal washing , dressing , metallurgy , iron and steel industry , zinc , aluminum processing industry and electronic work . Industry and other water treatment.
Application of cationic polyacrylamide
Cationic polyacrylamide (CPAM) exhibits positive electrical properties in acidic or alkaline media, and its molecular weight is usually lower than that of anionic or Nonionic polyacrylamide (Nonionic polyacrylamide). The properties of cationic polyacrylamide are mainly obtained by charge neutralization. This kind of flocculant has the function of removing turbidity and decolorizing. In alcohol plants, monosodium glutamate plants, sugar mills, meat factories, beverage factories, printing and dyeing factories, the use of cationic polyacrylamide is several or tens of times higher than that of anionic polyacrylamide, non-ionic polyacrylamide or inorganic salt.Because this kind of wastewater generally has negative charge, cationic polyacrylamide is suitable for high speed centrifuge, belt filter press, plate filter press and other special sludge dewatering machinery. Good agglomeration, easy to peel off the filter cloth and other characteristics. So the dehydration rate is high, the filter cake contains low liquid, the consumption is low, can greatly reduce the user's use cost. Can also be used in hydrochloric acid, medium concentration of sulfuric acid and other liquids, separation and purification of suspended substances contained therein. Therefore, the product is widely used in municipal wastewater treatment plants, breweries, food plants, tanneries, paper mills, petrochemical plants, oil fields, metallurgy, chemical industry and chemical industry. Makeup and other sludge dewatering treatment.
