AI Overview
Antifoams and defoamers in the pulp and paper industry are crucial for removing entrained air and surface foam to prevent production bottlenecks, sheet defects, and reduced drainage. Silicone-based defoamers are the industry standard for high-performance, offering fast knockdown and long-lasting efficiency in high-temperature or high-alkaline conditions, such as kraft pulping.
Common Types and Applications
- Silicone-Based: Primarily used in brownstock washing to reduce Entrained air and improve drainage.

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

Can caustic soda dissolve paper?
Role of caustic soda in paper pulping
Caustic soda is used in the pulping process to dissolve lignin and separate cellulose fibers from the wood. The process of dissolving lignin is called delignification, and it is essential to producing high-quality paper products.
