Antifoam is a chemical compound used to reduce foam in papermaking white water. It is typically added to the wet end of the papermaking process, where it helps to prevent foam from forming and interfering with the production process.  According to the different requirements and conditions, fatty alcohol antifoams and polyether defoamers are most acceptable in paper mills. They have their own advantage in paper process. Higher temperature conditions require higher antifoaming performance.

Fatty alcohol defoamers are highly effective in paper machines because they have excellent foam-breaking properties. They are also non-toxic, biodegradable, and non-irritating to skin and eyes. Additionally, fatty alcohol defoamers are highly compatible with most paper machine additives, such as wetting agents, sizing agents, and fillers. Furthermore, they provide good lubricity and reduce the risk of deposits on paper machine surfaces. Finally, fatty alcohol defoamers can be used at low concentrations and still provide good foam control.

Polyether Antifoams work high efficiently in paper process.

1. Polyether defoamers are highly effective in controlling foam formation and stabilizing foam levels in the wet end of papermaking white water systems.

2. They are non-toxic, non-corrosive, and have a low odor, making them an ideal choice for use in papermaking applications.

3. Polyether defoamers are also compatible with most chemicals used in the papermaking process, including retention aids, biocides, and other additives.

4. They provide excellent foam control and can be used at very low dosages, resulting in cost savings for the paper mills.
