 First, product introduction The polyacrylamide is called PAM, also called three coagulating agents, the molecular formula is CONH2[CH2-ch]n, is the striation water-soluble high polymer, the molecular weight between 300 - 18,000,000, the outward appearance powdery or colorless sticks the thick colloid shape for the white, not smelly, the neutrality, dissolves in the water, the temperature surpasses 120℃ time easy to decompose.
In the polyacrylamide member has the masculine gene (- CONH2) to be able with to disperse in the solution the suspended particle adsorption and the bridging, has the greatly strengthened flocculation, therefore widely uses in domains and so on water treatment and electric power, mining, coal dressing, asbestos product, petroleum chemical industry, papermaking, spinning and weaving, system sugar, medicine, environmental protection.
