The role of PAM powder (anion)

Polyacrylamide called PAM, commonly known as flocculants or cohesion agent, molecular formula: + CH2-CHn is a linear polymer, the molecular weight of 400-2000 million range, the solid product is white or slightly yellow powder, liquid is colorless viscous gel-like, soluble in water, when the temperature exceeds 120 ℃ easily decomposed.
PAM powder (anion) molecules with positive group (-CONH2), with the suspended particles dispersed in solution adsorption and bridging, there is a strong flocculation, PAM powder (anion) is widely used in water treatment and metallurgy, paper making, petroleum, chemical , textiles, mineral processing and other fields.
Starch factory and the loss of starch ethanol plants lees recovery: Now a lot of starch, starch factory wastewater containing many are dosing anionic polyacrylamide, starch particle coagulation and sedimentation, and then precipitate into pressure filtration through filter cake like, can be used for feed, ethanol plants can be applied anionic polyacrylamide alcohol dehydration, pressure filtration for recycling. Settlement for the river mud. Dry strength agents for paper. Additives used in papermaking, help rate agent. Before the pump inlet in the paper pulp storage pool by adding trace-type PAM-LB-3  PAM powder (anion)can fill with water retention in the online small fibers increased 20-30%. Savings per ton of pulp 20-30kg. For example: a large amount in the coal washing process wastewater, direct discharge of pollution of the environment, must be recycled after Shen Qing, recycling water, slime, but also valuable, but by natural subsidence, time consuming, while the water is not clear.Read more：http://www.chemical-chem.com/Papermaking-chemicals/PAM-powder-(anion)/
