Retention Aid for Paper Making Process

The Retention Aid for Paper Making Process generally uses cationic polyacrylamide as the main component. It is a molecular compound, generally white in powder or granular form, soluble in water, but insoluble in most organic solvents such as methanol and ethanol. Paper retention aid is used in paper making system to balance retention aid and filtration to achieve the best balance so that it can meet the demanding conditions of high-speed paper machines to resist high-end dynamic shear. The Retention Aid for Paper Making Process has different ionic and structural properties to meet a wide range of paper systems with pH values from acidic, neutral to weakly alkaline.

The Retention Aid for Paper Making Process we offer is cationic fine powder polyacrylamide with high retention efficiency and high quality products. It is widely used in major paper-making enterprises at home and abroad. Cationic polyacrylamide uses surface negative charge filler and polymer electrolyte cationization to increase the adsorption of filler particles and pulp fibers. This increases the retention rate of the filler, reduces the content of the filler in the white water to reduce the loss and lower the cost. It also reduces the concentration and ash content of the online pulp, prolongs the service life of the forming web, and improves the smoothness and opacity of the paper.
