【Storage, transportation and precautions】 Polyacrylamide itself is not toxic. Only when the inhaled amount is greater than five thousandths, it is harmful because the absorption of nutrients by the gastrointestinal mucosa is blocked. Residual acrylamide monomers in water purification flocculants are toxic, and food applications should be strictly controlled. Storage and transportation should pay attention to moisture-proof.
【Package specification】Dry powder 25kg/bag, inner bag with PVC film, outer bag with kraft paper bag.
Papermaking dispersing agent
Polyacrylamide dispersing agent is added in the papermaking process, which can effectively prevent the agglomeration of fibers and improve the uniformity of the paper. The company's papermaking dispersants can be dissolved within 60min. At low dosage, it can promote good dispersion of papermaking fibers and excellent paper forming effect, improve pulp uniformity and paper softness, and increase paper strength properties. . It is suitable for all kinds of toilet paper, napkins, facial tissue and other household paper and other tissue paper, etc. It can completely replace PEO6 in some paper mills.
Cationic retention and drainage aids
Cationic retention and drainage aids can improve the retention of fibers, fillers, fines and other chemicals, bring a clean and stable wet-end chemical environment, save the consumption of pulp and various chemicals, and reduce production cost, improve paper quality and paper machine productivity. A good retention and drainage aid is a prerequisite and necessary factor to ensure smooth operation of the paper machine and good paper quality. It is necessary to select suitable products according to different conditions. Usually, high molecular weight polyacrylamide is more suitable for the pH of the system (the pH range is 4-10).
