Polyacrylamide related introduction
Dec 20, 2017

In the domestic water treatment is the most widely used flocculant, is a synthetic polyacrylamide products, mainly divided into anionic, cationic, nonionic and amphoteric ion type. Polyacrylamide, often abbreviated as PAM (formerly also abbreviated as PHP) Various kinds of PAM for water treatment are essentially polymer products obtained by copolymerization of acrylamide and sodium acrylate in a certain ratio. There are a series of The product.

According to the molecular weight of polyacrylamide can be divided into ultra-high relative molecular weight polyacrylamide, high molecular weight polyacrylamide, medium molecular weight polyacrylamide and low relative molecular weight polyacrylamide. Ultra-high relative molecular weight polyacrylamide is mainly used for oil recovery of tertiary recovery, high relative molecular weight polyacrylamide is mainly used as flocculant, medium molecular weight polyacrylamide is mainly used as paper dry strength agent, low molecular weight polyacrylamide mainly used Make dispersant.

Polyacrylamide belongs to high polymer. Professional for a variety of difficult to deal with the treatment of wastewater and sludge dewatering treatment. (Sludge dewatering generally uses cationic polyacrylamide) in municipal sewage and sludge treatment of paper and printing and dyeing industry, widely used.
