There are many kinds of paper making dispersant. Mainly include the carboxylic acid salts such as dispersant, starch modified LBD - 1. And it should have pyrolysis, with the characteristics of temperature increases the viscosity decrease rapidly, to ensure that does not affect the drying of the performance of original fiber in the paper.

    Ultra high molecular weight of anionic polyacrylamide is water-soluble organic polymer, soluble in water and form a high viscosity liquid, can promote the papermaking fibre under low add good dispersion and excellent paper molding effect, improve the evenness and paper pulp softness, also can increase the strength of paper. Used in paper coating, paper making dispersant dispersion with high efficiency, less paint viscosity stability and foam, non-toxic, non-corrosive, can make the coating of solid content increased, and good liquidity and scrub resistance, can keep paper gloss and not easy to change mould. Paper making dispersant can also improve the manufacture paper with pulp speed, save beating time, reduce energy consumption, with remarkable economic benefit.

    Above the product molecular weight of 20 million, and the solubility generally within 1 hour, aqueous solution and product has good filtering performance, used for all kinds of toilet paper, napkins, paper towels, white paper also widely used in culture, there is light thin sheet of paper and newsprint manufacture paper with pulp.
