In the intricate world of paper manufacturing, the quality and efficiency of production processes are paramount. Polyethyleneimine (PEI), a versatile cationic polymer, plays a significant role in achieving superior paper products. NINGBO INNO PHARMCHEM CO.,LTD., a key supplier of specialty chemicals in China, highlights the substantial benefits PEI brings to the paper industry. PEI functions effectively in paper manufacturing primarily in two key areas: as a retention aid and as a wet strength agent. Its cationic nature allows it to interact with negatively charged cellulosic fibers and fine particles in the pulp slurry. As a retention aid, PEI helps to retain these valuable components within the paper sheet, reducing their loss in the white water system. This leads to improved material efficiency and better formation of the paper web. Furthermore, PEI acts as a wet strength agent, improving the mechanical integrity of paper when it is saturated with water. This is achieved through PEI’s ability to form cross-links and hydrogen bonds between cellulose fibers, providing enhanced strength and durability to the final paper product. This attribute is particularly crucial for paper products that are expected to maintain their structure under moist conditions. Manufacturers in the paper industry can significantly benefit from incorporating PEI into their processes. Its use can lead to a reduction in beating degree of pulp, improved paper dehydration ability, and an overall increase in production capacity. The enhanced dryness of the paper, typically by 1%-4%, and the potential for increased production capacity by 5%-20%, underscore the economic advantages of using PEI. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supporting the paper industry with high-quality PEI that meets specific manufacturing needs.
