OY IEnvironmental Protection is a manufacturer of polyacrylamide in Jiangsu. In recent years, the domestic paper industry has made rapid progress, ranking third in the world and increasing year by year. There is a shortage of wood pulp, especially long fiber carpenters, in our country. Many papers need to be matched with short fiber broad-leaved wood pulp, straw pulp, and recycled pulp, which will inevitably lead to a decrease in paper strength. Therefore, measures need to be taken to improve the strength of paper.

The strength of paper is controlled by the strength of the bond between fibers. The use of paper reinforcement agents is a good way to strengthen the bond between fibers, which can avoid the increase in paper tightness, temperature deformation, opacity, absorbency, breathability, and even tear resistance caused by the increase in beating degree. We produce "Cationic Polyacrylamide for Paper Industry", and currently the main paper reinforcing agent used is cationic polyacrylamide. Cationic polyacrylamide is relatively inexpensive and has a significant reinforcing effect on paper, as well as a significant retention effect on fillers and fine fibers. The pH range of cationic polyacrylamide for papermaking can achieve good results from acidic to neutral. Adding cationic polyacrylamide as a dry strength agent to pulp can improve the bonding strength between fibers, making the paper have strong resistance to breakage, folding, and paper strength. As a wet strength agent, it has excellent performance, low dosage, and low cost. Adding a small amount can achieve good dry and wet strength.

Polyacrylamide, as a papermaking additive in the paper industry, not only plays a role in retention and filtration to improve the strength of paper, but also reduces costs and increases economic benefits. As a polyacrylamide manufacturer with many years of production experience, OYI Environmental Protection welcomes inquiries from customers.
