Hydrolyzed polyacrylamide is a high molecular polymer obtained by hydrolysis of acrylamide. Its ionic characteristics are anionic (APAM). The molecular chain contains a certain number of polar groups and has a bridging function.
The characteristics and performance of hydrolyzed polyacrylamide are closely related to its structure, molecular weight and other factors. Anionic polyacrylamide (APAM) appears as white powder with a molecular weight ranging from 6 million to 25 million. It is mainly used for flocculation, sedimentation and clarification of various industrial wastewaters.

The price of anionic polyacrylamide ranges from 0.6-1.5 US dollars per kilogram, depending on the molecular weight.
Anionic polyacrylamide has the following features:
1. Clarification and purification.
2. Rapid precipitation.
3. Filtration promotion.
4. Thickening.
It can fully meet the requirements of waste liquid treatment, mineral processing, coal washing, papermaking and other fields.
- Water treatment field
Wastewater treatment: As a high-efficiency flocculant, it is used in the treatment of industrial wastewater such as steel mills, electroplating plants, and coal washing plants to accelerate the sedimentation of suspended particles and improve clarification efficiency.
Drinking water purification: Remove suspended matter and microorganisms through charge neutralization and adsorption to optimize water quality.
- Oil production field
As an oil displacement agent and drilling mud conditioner, it can increase oil well production and oil recovery efficiency; as a drag reducer and thickener, it can optimize oil field development technology.
- Papermaking field: Enhance paper strength, reduce raw material loss, and increase filler retention rate.
- Textile field: As a sizing agent and finishing agent, it can improve the antistatic, flame retardant, and color fastness of fabrics.
Anionic polyacrylamide packaging, storage and transportation and precautions:
Packaging uses 25Kg plastic-lined woven bags or paper-plastic composite bags, or packaging according to user requirements. During storage and transportation, pay attention to heat and moisture protection to prevent packaging damage. Dry powder products will absorb moisture and form lumps if exposed for a long time.
