Polyscrylamide brief name PAM, so-called flocculant or coagulate, and includes cation and anion, the molecular weight is between 400-18,000,000, it looks like white or t light yellow powder, liquidity is in the form of being no color dense colloid, dissolved in water easily, easily resolved with the temperature of more than 120 °C.
1.Classification:This product is divided into colloid and powder, and falls into the non- ion type and anion type according to the species (calling partly-solving water object)
2, Molecular formula: (CH2-CHCONH2)n(non- ion type)
(CH2-CHCONH2) n(CH2-CHCOOHa) m (anion type)
3, Physical property
Colloid product has no color, transparent, not poisonous, and has no corrosion. Powder is white. Both can be dissolved in water, but almost dissolved in organic solvent. The product of different species, different molecular weight has different property.
The colloid product is mainly anion types, and this product mainly used for drilling petroleum, textiles, chemical engineering, coating, wastewater treatment etc.
The powder product is mainly anion types, and according to usage, non- ion type and different dissimilarity to water can be produced. This product is mainly used for petroleum, smelting, choosing mines, paper-making, textiles, sugar-making, cutting stones, chemical engineering, medicine and wastewater treatment etc.
