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.
