1、 Application field
Polyacrylamide is widely used in mining and metallurgy, including coal washing, beneficiation and metallurgy. In these processes, polyacrylamide is used as flocculant and filter aid to flocculate with mineral particles in liquid, accelerate the concentration of fine particles, promote solid-liquid separation, improve production efficiency, reduce tailings loss and reduce cost.
2、 Product characteristics
The company's products have the characteristics of good solubility, fast flocculation reaction, solid flocs, low content of suspended solids in filtrate, strong adaptability and so on.

4、 Method of use
1. This product is usually prepared into a 0.1% ~ 0.3% solution for standby; 2. During dissolution, the product shall be evenly dispersed, dissolved by stirring, and the stirring speed shall be controlled at 50 ~ 250rpm; 3. Avoid using metal dissolving tanks that are easy to affect water quality; 4. Increasing the water temperature can accelerate the dissolution rate, but generally not more than 50 ℃.
5、 Packaging, transportation and storage
The products are packed in paper plastic composite bags, 25kg per bag or determined according to user needs, and the shelf life of the products is 2 years.
