Properties:
Polyacrylamide (PAM) is a water-soluble polymer and is insoluble in most organic solvents. It has good flocculation properties and can reduce the frictional resistance between liquids. According to its ionic characteristics, it can be divided into four types: nonionic, anionic, cationic and amphoteric. It is widely used in water treatment , papermaking, petroleum, coal, mining and metallurgy, Geology, textile, construction and other industrial sectors,

Usage:
- When used alone, it should be prepared into a dilute solution. The general concentration is 0.1 - 0.3% (referring to solid content). Neutral, low-hardness water should be used for dissolution, and the water should not contain suspended substances and inorganic salts.
2. When treating different sewage or sludge, appropriate products should be selected based on the treatment process and water quality. The dosage of the agent should be determined based on the concentration of the water to be treated or the moisture content of the sludge. 3. Carefully
select the placement point and mixing The speed must not only ensure the uniform distribution of the polyacrylamide dilute solution, but also avoid the breakage of the floc.
4. The solution should be used as soon as possible after preparation. -
Packaging and storage:
- PAM is packed in polyethylene plastic bags and woven bags, with a net weight of 25kg per bag. Stored in a cool and dry warehouse, the shelf life is one year.

Safety and protection:
Weakly acidic, pay attention to labor protection during operation, avoid contact with skin, eyes, etc., rinse with plenty of water after contact.
