Dry Strength Agent

I. Introduction Papermaking dry strengthen agent is our company`s new and self-developed products that using imported raw materials. Its mechanism of action is: dry strength agent use polymer mesh structure to increase hydrogen bonding number in the mutual area of fiber to fiber. Dry strength agents in the combination area of long-chain polymers can be deformed, thus increasing the bond toughness. It could improve paper strength by the bridging ability formed by chemical function to make fibers and fibers have "implicated" II.
