Analysis of technical knowledge about paper defoamers
Compared with traditional defoamers, paper-making defoamers have better sustainability, and can exert excellent defoaming and anti-foaming effects with a very small amount of addition. In addition, the paper-making defoamer significantly reduces the amount of air inflow and the resulting foam, thereby improving the water discharge of the pulp mat. It can quickly eliminate the foam produced by lignin and other surfactants, and has excellent effects in pulping, pulp washing, papermaking and sizing, and it defoams quickly.
The advantages of paper defoaming are as follows:
1. Maintain excellent continuous defoaming ability under low dosage;
2. Excellent defoaming and defoaming properties;
3. Quickly and thoroughly improve filter drainage;
4. It has good mutual solubility with black liquor and is suitable for the production conditions of pulp mills;
5. Improve rinsing efficiency;
6. Contribute to dehydration, reduce the moisture content of the pulp, and reduce the energy consumption of the evaporation process;
7. Reduce salt loss and improve the quality of pulp and paper;
8. Reduce the amount of bleaching chemicals to facilitate environmental protection requirements.
9. Biodegradable, non-toxic and harmless.
Paper washing and defoaming agent is used in the production line of alkaline pulping, alkaline pulping, paper washing, bamboo pulp, sugarcane pulp, neutral pulping, pulp, paper washing, pulp rinsing, and black liquor washing in the pulp industry. A defoamer designed to control foam and used in the production of plant fiber pulp.
