transpare viscous liquid Cationic Pulp Chemical Dry Strength Agent for Corrugated Paper
Introduction
Dry Strength Agent LSD-15 can be widely used in papermaking of packaging paper, household paper, newsprint, cultural paper and other paper.
It can effectively improve the paper folding strength, bursting strength, stiffness, ring crush strength and so on.
On papermaking system with much anionic impurities or high electrolyte concentration, the effect is particularly evident.
At the same time it has retention effect to flake fine and filler can reduce the loss of fibers and linting and dusting phenomenon.
It can produce enough dry strength and allows the use of inexprensive fiber or a higher proportion of secondhand fiber.
Features:
This is a kind of newly developed dry strength agent, which is a copolymer of acrylamide and acrylic, it is a kind of dry strength agent with amphoteric combo, it can enhance the hydrogen bonding energy of the fibers under the acid and alkaline environment, greatly improve the dry strength of paper (ring crush compression resistance and bursting strength). Simultaneously, it has more function of retention and sizing effect improving.
