This is a kind of newly developed dry strength agent, which is a copolymer of acrylamide and acrylic, it is a kind of dry strength agent with amphoteric combo, it can enhance the hydrogen bonding energy of the fibers under the acid and alkaline environment, greatly improve the dry strength of paper (ring crush compression resistance and bursting strength). Simultaneously, it has more function of retention and sizing effect improving.
It is a new type of dry strength agent, is widely used in cardboard paper, bobbin paper, household paper, newsprint, cultural paper, and so on. It can effectively improve the dry strength of the paper (folding strength, bursting strength, deflection and ring crush compression resistance) It has a particularly obvious effect on the paper making system with more anion impurities or higher electrolyte concentration. It also has the function of retention for fiber fines and fillers, reducing the fiber to drain, farina and fibril to drop out.
1.Effectively improve the dry strength of the paper( folding strength, bursting strength, deflection and ring crush compression resistance)
2. Improve the retention ratio of fiber fines and fillers and filtering performance.
3. Reduce the dosage of the cationic starch, polyacrylamide and other retention aid.

Dilution ratio: LSD-15/20 and water on 1:20-40, it may be added into the middle of stock proportioner and machine chest, it may also be continuously added with metering pump in the high level tank. Adding quantity is 0.5-2.0% (generally speaking, is 0.75-1.5%, virgin pulp (oven dry stock), adding concentration is 0.5-1%.
