Pam Chemical Water Treatment CAS No. 9003-05-8 Polyacrylamide Powder

Polyacrylamide is abbreviated as PAM. It is a linear high molecular polymer and one of the widely used water-soluble high molecular polymers. According to ionic characteristics, it can be divided into anionic polyacrylamide (APAM), cationic polyacrylamide (CPAM) and non-ionic polyacrylamide (NPAM). Polyacrylamide and its derivatives can be used as effective flocculants, thickeners, paper-making enhancers and liquid drag reducers, etc., and are widely used in water treatment, papermaking, petroleum, coal, mining and metallurgy, geology, textiles and other fields. And other industrial sectors.

How to use polyacrylamide and matters needing attention:
1. Powder or granular polyacrylamide cannot be directly added to sewage. It must be dissolved in water before use, and then the aqueous solution is added to the sewage in a certain proportion.
2. The water to dissolve PAM should be clean tap water. Generally, the pH value of tap water can meet the requirements of preparing flocculant solutions.
3. Normal water temperature is enough, too high water temperature will cause polyacrylamide to degrade rapidly.
4. The concentration of polyacrylamide PAM solution is generally 0.1 to 0.3%.
5. Due to the poor shear performance of polyacrylamide, long-term high-speed stirring will cause product degradation and reduce its use effect. Generally, the stirring speed during the dissolution process is preferably between 60-120 revolutions per minute.
6. In the dissolution process, the speed of adding flocculant should be as slow as possible, and at the same time, it should be slowly dispersed into the vortex of water to prevent the flocculant particles from sticking to each other after adding. Into the water.
