DEFOAMERS FOR PULP AND PAPERMAKING APPLICATIONS.

摘要

A defoamer made from a composition that has at least one triglyceride oil or triglyceride oil mixture, at least one silicone, at least one silicone-triglyceride stabilizing agent, hydrophobic silica particles, optionally one or more surfactants and/or dispersants, and optionally one or more thickeners, and optionally one or bore biocides. The defoamers described herein have utility in controlling foam in industrial applications. Typically, the defoamer can be used to control foam in pulp and paper applications.
