Product Manual

Product Introduction

The defoamer for paper pulping black liquor is specially formulated from polysiloxane, polyether, alcohol esters, dispersants, and other components through a unique refining process. It is designed specifically for defoaming in paper pulping, black liquor, and pulp washing production lines. This product is resistant to high temperatures, strong alkalis, and high shear forces. It maintains excellent continuous defoaming performance even at low dosages. It also offers good emulsion stability and is unlikely to adhere to equipment or mesh fabrics.

Product Features

1. Resistant to acids and alkalis, high shear, and suitable for a wide temperature range.

2. Low dosage requirement, cost-effective, excellent product stability, and easily dispersible in water.
