Polyacrylamide (PAM) for paper making is a kind of high polymer with polyacrylamide as the main component, which belongs to water soluble linear polymer electrolyte. Its molecular chain contains a large number of active groups (such as amide group, ion group), through adsorption, bridge, electric neutralization and other functions, plays a key role in the papermaking process.
Features and advantages
Economical and efficient
A small amount of addition can significantly improve the retention rate and paper performance, reduce the consumption of fiber and filler, and save production costs.
Environmentally friendly
Biodegradability is better than traditional inorganic flocculants (such as aluminum salts), reducing chemical residues in wastewater treatment.
Strong process adaptability
According to different paper machine types (long net, circular net), pulp types (wood pulp, grass pulp, waste pulp) and paper copying process (acid/neutral/alkaline paper copying), product parameters can be customized and adjusted.
