Occ--dry Strength Agent Ds102

These OCC--Dry Strength Agent DS102 is a new amphoteric dry strength agent, which is a copolymer of acrylamide and acrylic. In acid and alkali environment, it can enhance the hydrogen bond between the fibres, and significantly improve the dry strength of the paper. (Ring crush strength and bursting strength)
In the meantime, LYAR DS 102 also has the function of retention and can improve the sizing efficiency
Application
Usually, the pre-dilution of LYAR DS 102 is recommended before adding into the slurry system. Set the add position in the place where can be sufficiently stirred to ensure the uniform adding.
LYAR DS 102 is usually diluted with water at the ratio of 1:20-40. It can be added at the entrance to the pump of mixing slurry pool and slurry pool, and also can be added by metering pump continuously in a head box. Recommended dosage is 0. 5~2. 0% relative to the dry pulp, adding concentration is 0. 5-1. 0%.
LYAR DS 102 has the characteristic of amphoteric. For lowering the cationic requirement in the system and the resistance of cationic garbage, it has good effect and can improve the cleanliness of the paper making system. In the meantime, it can also improve the retention performance. Special care on the retention change is required when adding this product.
For certain application, the usage of LYAR DS 102 should also follow the operating instructions of our company.
