While anionic and cationic polyacrylamides are well-known for their roles in retention and wastewater treatment, non-ionic polyacrylamide (NPAM) offers a unique set of benefits for papermaking processes. Its versatile properties make it an invaluable additive for enhancing filtration, improving dry strength, and acting as a dispersant. NINGBO INNO PHARMCHEM CO.,LTD., as a prominent supplier in China, offers high-quality NPAM to meet the diverse needs of the paper industry.

One of the primary applications of non-ionic polyacrylamide paper additive is in improving the filtration of pulp. In papermaking, efficient water removal from the pulp slurry is crucial for speed and quality. NPAM aids this process by flocculating fine particles without introducing a strong charge, which can sometimes interfere with other chemical systems in the mill. This controlled flocculation helps create a more open and permeable sheet, facilitating faster drainage on the paper machine.

Furthermore, NPAM contributes to the dry strength of paper. By adsorbing onto fiber surfaces and forming hydrogen bonds, it acts as a dry strength enhancer, similar to other PAM types. This improvement in tensile strength, burst strength, and folding endurance is vital for producing durable paper products. The efficacy of NPAM can be particularly pronounced in specific papermaking scenarios where charge neutrality is preferred or beneficial.

NPAM also functions effectively as a dispersant. In certain applications, it can help to keep fine particles suspended and prevent them from agglomerating undesirably, which can be important for achieving a uniform sheet formation or in specific coating applications. Its ability to modify slurry rheology makes it a valuable tool for process control.

The versatility of polyacrylamide papermaking, as exemplified by NPAM, highlights its importance across various stages of paper production. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing reliable and effective non-ionic polyacrylamide solutions.
