Key Types of White Water Defoamers
- Fatty Alcohol Defoamers: Known for fast action and high efficiency in waste paper processes without affecting sizing.
- Polyether Defoamers: Highly effective for foam control, providing excellent degassing in wet-end systems, particularly in paper machine white water.
- Silicone-Based Defoamers: Suitable for systems experiencing severe foam and for high-speed paper machines.
Key Considerations for Selection
- Application Method: Defoamers should be added at points of high foam concentration, such as the white water tray under the felt, the white water pool outside the machine, or the headbox.
- Compatibility: Agents must be compatible with other additives like surfactants, retention aids, and sizing agents.
- Performance: Good defoamers, as discussed on Nanjing Antifoam Environmental Technology Co., Ltd, improve sheet formation and reduce pulp washing issues.

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 the white water in papermaking?
These suspended solids create a milky or cloudy appearance in the drainage water, hence the term “white water.” To improve the efficiency of the papermaking process, the white water from the paper forming process is collected and treated to recover the suspended solids and clarify the hot water.May 9, 2024

What is a defoamer used in pulp and paper?
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.
