IOTA 1831 is a especially alkali resistance defoaming agent. It used modified polysiloxane as the main material, equipped with high efficiency, good dispersion auxiliaries, special alkali emulsifier, siloxane adduct compound and into a new type of pulping dedicated defoaming agent. In the process of alkaline pulping, because of the pulping raw material containing natural substances, such as fatty acid, resin acid and adding sodium hydroxide, sodium sulfide and other chemical reactions produce saponification, foaming material such as residual alkali and alkali lignin. Coupled with the high polymer material such as cellulose of bubble effect, and the size of the air flow and mixed into the slurry system, has formed a large number of stable foam. JY - 831 it can rapidly eliminate the bubbles, because of the lignin and other surfactants in the pulp, pulp, paper sizing effect is obvious, when the fast defoaming rate, less dosage of late, the price is cheap, no pollution.
