Stone plants use Anionic Polyacrylamide and polyaluminium chloride

Polyacrylamide is a polymer organic flocculant, mainly classified into: anionic polyacrylamide (APAM), cationic polyacrylamide (CPAM), nonionic polyacrylamide (NPAM). It is widely used in petroleum exploration, water treatment, textile, printing and dyeing, papermaking, mineral processing, coal washing, medicine, sugar refining, breeding, building materials, agriculture and other industries.


Anionic polyacrylamide (APAM) is a water-soluble polymer, mainly used for flocculation and sedimentation of various industrial wastewater, sedimentation clarification treatment, such as wastewater from steel plants, wastewater from electroplating plants, metallurgical wastewater, coal washing wastewater, etc. Mud dehydration, etc. It can also be used for clarification and purification of drinking water. Because its molecular chain contains a certain number of polar groups, it can absorb solid particles suspended in water to bridge between particles or agglomerate particles to form large flocs through charge neutralization, so it can accelerate particles in suspension. The sedimentation has a very obvious effect of accelerating the clarification of the solution and promoting filtration.

Anionic polyacrylamide technical indicators

Appearance white particles Solid content ≥88%
Molecular weight 6-20 million Hydrolysis degree 10-35%
Dissolving time ≥90 minutes Odor Odorless
Corrosiveness non-corrosive
Thermal stability easy to decompose when the temperature exceeds 120°C

Application fields of polyacrylamide

1. Coal washing plants choose polyacrylamide for coal slurry sedimentation and concentration tailings filtration, please choose anionic polyacrylamide, nonionic polyacrylamide, and low cationic polyacrylamide.
2. Please choose anionic polyacrylamide or nonionic polyacrylamide for wastewater in the paint industry. For the treatment of paint wastewater, the traditional method is to directly coagulate the mixed wastewater. The treatment effect is not ideal, the effluent quality is unstable, and it is difficult to meet the discharge standard.
3. Please choose cationic polyacrylamide for biological treatment of waste liquid in dairy industry and sludge treatment.
4. Anionic polyacrylamide, non-ionic polyacrylamide and low cationic polyacrylamide are used for the treatment of electroplating wastewater containing cyanide oxide.
5. Anionic polyacrylamide, low cationic polyacrylamide and non-ionic polyacrylamide are used for copper mining tailings wastewater treatment.
