Biological Drainage Enzyme
1：Product Introduction
Soluble colloidal substance play obvious drainage preventing action during production. Lerkam biological drainage enzyme is exclusively produced for papermaking industry pulp material fiber modification. Through selectively reducing the soluble colloidal substance in the pulp to reach the effect of drainage, this product has no hurt to fiber and very effective to pulp modification.
