Papermaking dry strength agent LQ322 is widely used in the production of packaging paper (corrugated paper, kraft paper, bobbin base paper, etc.), cultural paper and special paper. It can effectively improve the dry strength of paper and improve the physical properties of paper. performance. It produces sufficient dry strength to allow the use of inexpensive fiber stock or a higher proportion of secondary fibers.

LQ322 is an amphoteric polyacrylamide dry strength agent for paper with a network structure. Its macromolecular structure chain contains both anionic and cationic functional groups. It is cationic in general and not only has strong anti-interference ability to hetero ions. , and the special network structure can more effectively improve the ring compressive strength, tensile strength, burst strength and interlayer bonding force of the cardboard than the linear structure polyacrylamide DSR, and has good retention, Drainage effect.
