Polyacrylamide for papermaking is a white granular solid. There is no special smell, and other colors can be white or milky white as each batch is different. When polyacrylamide for papermaking is dried, the particles are dispersed and there is no stickiness. Use characteristics of polyacrylamide products for papermaking 1. Flocculation: PAM can neutralize suspended substances through electricity, bridging adsorption, and flocculating. 2. Adhesiveness: It can play the role of adhesion through mechanical, physical and chemical effects. 3. Resistance reduction: PAM can effectively reduce the frictional resistance of the fluid. Adding a small amount of PAM in the water can reduce the resistance by 50-80%.

Polyacrylamide for papermaking is widely used in the field of papermaking as retention aids, filter aids, leveling agents and other agents. The role of polyacrylamide for papermaking is to improve the quality of paper, improve the dehydration performance of the slurry, increase the retention rate of fine fibers and fillers, and reduce the consumption of raw materials and environmental pollution. The effect used in papermaking depends on its average molecular weight ionic properties, ionic strength and the activity of other copolymers. Non-ionic polyacrylamide for papermaking is mainly used to improve the filterability of pulp and increase the retention of fibers and fillers. Anionic polyacrylamide copolymers for papermaking are mainly used as dry and wet strengthening agents and retention agents for paper.

The cationic polyacrylamide copolymer for papermaking is mainly used for papermaking wastewater treatment and filter aid, and it also has a good effect on increasing the retention of fillers. In the paper industry, Ciba Refining is mainly used as a papermaking aid. Polyacrylamide for papermaking is used as a cationic retention and drainage aid C8560, which is widely used in the production of cultural paper, newsprint, cardboard and special molded products. It is recommended to add it at the thin pulp, and the addition point should be selected at the last shear point before the sheet is formed, and the amount is between 0.01-0.1% (relative to the absolute dry pulp). It can be used in unit, binary and particle retention systems.

Polyacrylamide for papermaking is widely used in the field of papermaking as retention aids, filter aids, leveling agents and other medicaments. The role of polyacrylamide for papermaking is to improve the quality of paper, increase the retention rate of fine fibers and fillers, and reduce the consumption of raw materials and environmental pollution. The effect used in papermaking depends on its average molecular weight, ionic strength and the activity of other copolymers. Non-ionic polyacrylamide for papermaking is mainly used to improve the filterability of pulp, increase the strength of dry paper, and increase the retention of fibers and fillers; anionic polyacrylamide copolymers for papermaking are mainly used as dry and wet strengthening agents for paper. Resident agent

In the textile industry, PAM is used as a sizing agent and finishing agent for fabric post-processing, which can generate a mild, wrinkle-resistant, and mold-resistant maintenance layer. With its strong hygroscopicity, it can reduce the thread breakage rate during spinning; PAM can prevent static electricity and flame retardancy of the fabric as a post-treatment agent; when used as a printing and dyeing auxiliary, PAM can make the product adhesion fast and bright It can also be used as a non-silicon polymer stabilizer for bleaching. In addition, PAM can also be used for efficient purification of textile printing and dyeing wastewater.

Polyacrylamide for papermaking is widely used in the field of papermaking as retention aids, filter aids, leveling agents and other medicaments. The role of polyacrylamide for papermaking is to improve the quality of paper, improve the dehydration function of the slurry, improve the retention rate of fine fibers and fillers, and reduce the consumption of raw materials and environmental pollution. The role used in papermaking depends on its average molecular weight, ionic properties, ionic strength and the activity of other copolymers. Polyacrylamide for non-ionic papermaking is mainly used to improve the filterability of pulp, add dry paper strength, and improve the retention rate of fibers and fillers.
