AI Overview
Effective antifoams and defoamers for the papermaking wet end include fatty alcohol dispersions, polyether/polyester types, and silicone-based emulsions, specifically designed to reduce entrained air, improve drainage, and eliminate surface foam. These products are typically added to the white water pit, breastbox, or headbox to combat foam caused by agitation, suction, and chemical additives.

What are the disadvantages of Antifoaming agents?
Disadvantages of Silicone Based Defoamers
Silicone-based antifoam is relatively poor durability. Silicone is oil soluble, and it reduces the defoaming effects in oil systems. It is not ideal for long-term high-temperature resistance and strong alkali resistance.Jan 20, 2022

What is a defoamer in the paper industry?
Defoamer for Papermaking (White Water Pool Process)
The paper defoamer, also called pulp mill defoamer, removes air from the foaming medium before breaking the foam. Fatty alcohol defoamers, such as high-carbon alcohol defoamers, are commonly used for this purpose.
