Dry Strength Agent

Dry Strength Agent with net structure is the copolymer of acrylamide,
its large molecule chain has zwitterion functional group which have
strongly the anti-jamming ability to impurity ions. It can improve the
ring crush strength, tensile strength, bursting strength and interlayer
bindings force, meanwhile, it has good performance in retention and
drainage. It has stable strengthen effect even if papermaking condition
changed (PH, Aluminum sulfate and pulp).Besides, under closed system
(circulation use of water), especially high temperature conductivity, it
still can keep the high strength effect.
