High quality polyacrylamide (NPAM) is a linear polymer with high molecular weight and low ionic degree. Non-ionic polyacrylamide (NPAM) has very obvious effects of accelerating solution clarification and filtration. Non-ionic polyacrylamide (NPAM) is widely used in coal mine washing, textile industry auxiliaries, weak acid sewage treatment, metallurgy, mineral processing, chemical grouting agent, soil moisture agent, etc.
