Anionic polyacrylamide (APAM) is a water-soluble polymer, which is mainly used in the flocculation settlement, precipitation and clarification treatment of various industrial wastewater such as steel mill wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and so on. It can also be used for the clarification and purification of drinking water. Because its molecular chain contains a certain number of ji groups, so it can accelerate the settlement of particles in the suspension, obviously accelerate the clarification of the solution, through the adsorption of solid particles in the suspended water, so that the bridge between particles or through the charge neutralization to form a large flocculant. Characteristics and Application Characteristics of anionic polyacrylamide:
1, good water solubility, can also be completely dissolved in cold water.
2, add a small amount of this anionic polyacrylamide products, can receive great flocculation effect. Generally only need to add 0.01~10ppm(0.01~10g/m3), can play a full role.
3, the use of anionic polyacrylamide products and inorganic flocculants (polyferric sulfate, polyaluminum chloride, ferric salt, etc.), can show greater results. Application scope of anionic polyacrylamide:
4. Suitable for textile, printing and dyeing industries. Polyacrylamide as fabric processing sizing agent, finishing agent, and a layer can produce soft, wrinkle resistant, mildew resistant protective layer. The breakage rate of spinning can be reduced by its strong hygroscopic property. Polyacrylamide finishing agent prevents static electricity and flame retardants in the fabric. Polyacrylamide can be used as a printing and dyeing additive to give products high adhesion and brightness. It can also be used as a non-silicon polymer stabilizer for bleaching.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
