papermaking dispersant polyacrylamide

الوصف

Polyacrylamide is used in the production process of papers,such as white board,coated paper,paperboard and printing paper,which use wood pulp,straw pulp and waste water pulp as raw material.Mainly used as reinforcing agent in papermaking process.as fine fiberfill retension agent and filter aid.
When used as retention agent and filter aid,pam can increase the retension of net fibers and other wet part additives,speed up network filtration and dry part dehydration.Retension of ash is significantly increased.Retension rate of first layer fiber is averagely increase more than *0%.Retension of strch is increased,creating favorable conditions for the use of srarch as interlayer reinforcing agent.
Paper selling profits are increased,Meanwhile,filler cost is also cut down.Water filtration ability is greatly improved,which gurantees a corresponding increase of speed at ***0%.Generally speaking,large molecular weight polymers have better retension performances while low molucular weight polymers have better filtration ability.When used as dispersant,it can improve the uniformity of paper sheets.
Can be used as flocculant for paper pulp wastewater treatment.Remove the organic parts of the wastewater.To be combined used with inorganic flocculants.It can separate out the precipitation,with a cleanness rate at ****0%.It can relieve the overproof problem of wastewater's COD.
