Polyacrylamide
Poppularly called flocculant, PAM has the molecular formular of +CH2-CHn, Linear polymers, molecular weight of 4,000,000—20,000,000, strong flocculation, easily soluble in water, dissolute above 120. It appears white and light-yellow at solid, colorless vicous colloid at liquid.
With this special structure, it can easily adsorpte the suspended solids to purify the water thoroughly. So it is widely used in metallurgy, papermaking, petroleum, chemical industry, textiles and ore dressing.
