DPS-480 Viscose Additive Modifier
【Applications】 Viscose additives improver and activator, applies to all sulfate and sulfite dissolving pulp cellulose-based, can improve the affection of cellulose impregnated alkalizing; For different types of pulp (cellulose), the series of DPS viscose additive modifier are improving the reaction of alkali cellulose in the process of xanthation with CS2, then improves filtration of the viscose and improves spinnability.
【Usage】
- Dissolving pulp plant can spray 10% DPS-480 diluted before pulp drying.
- Viscose fiber plant can add DPS-480 to the alkali cellulose in alkali impregnation process or alkali fiber crushing process.
- Recommended add-on: 0.5 to 2.0 g per kilogram of cellulose.
