Why use paper pulp defoamer?

09-09-2024

In the papermaking pulping process, usually encountered a variety of foam problems, are due to the lack of addition of pulping defoamer caused by the presence of these bubbles not only have an impact on the use of equipment, but also destroy the quality of paper.

As the air bubbles in the pulp have an important impact on the operation of the paper machine and the quality of the finished paper, so it is necessary to eliminate the foam, and some of the effects are also summarized below:

(1) high bubble content, not only affects the net dewatering caused by paper disease, and bubbles will produce cavitation, so that the operating performance of the pulp pump down, increase energy consumption; 

(2) bubbles affect the stability of the entire sizing system, which can cause the sizing pump tripped, shutdown; 

(3) bubbles lead to pressure fluctuations in the pulp pipe and other pressure devices; 

(4) bubbles in the pulp is not a big impact on the speed of the lower speed of the machine, but the high speed paper machine has a significant impact. But the high-speed paper machine has a significant impact.


Paper pulp defoamer is a kind of high efficient compound defoamer which is refined by special process with many kinds of defoaming active substances for the characteristics of black liquid foaming of paper pulping. Defoamer for paper pulp has excellent foam inhibition and defoaming effect on various foaming systems with water as medium.


Special properties of defoamer antifoam

Low dosage of pulping defoamer, rapid defoaming.

Paper pulp defoamer is non-toxic and odorless, which is conducive to production safety.

Antifoam agent's unique anti-foam effect, which is favorable to the flow of black liquid.
