Fatty Alcohol Defoamer Use
In papermaking, white water is 20-60°C. Air mixes in during circulation, causing foam. Also, leftover chemicals from the additives create small bubbles in the white water. After adding papermaking defoamers, the foam is gone. The defoamers’ strong suppression prevents new foam during later production stages.
Also, in addition to fillers and pigments, additives must be added in the coating prep process. These include dispersants and wetting agents. They will cause foam during the coating process. Adding paper defoamer avoids problems caused by foam. It prevents uneven coating and inconsistent thickness. This improves the coating quality.

A defoamer is a surfactant. It eliminates foam caused by vibrations and other factors during production. Fatty alcohol defoamer is silicone-free. It leaves no silicone residue. Using fatty alcohols as defoamers has advantages as below:
1. It quickly removes gases from pulp and eliminates foam in water.
2. It is stable at high temperatures and strong alkalis. So, it is very effective.
3. It is cheap and widely used in papermaking, white water systems, and wastewater treatment.
Many papermaking defoamers are available. They include polyether, fatty, silicone, kerosene, and fatty alcohol types. Each suits a different process. These defoamer types have unique traits. They address foam issues in papermaking and suit various scenarios. The specific types are as follows:
1. Fatty Alcohol Defoamers
2. Polyether Defoamers
3. Fatty Defoamers
5. Kerosene Defoamers
In summary, choosing papermaking defoamers is based on the specific application. Each type has its pros and cons. Fatty alcohol defoamers are now the top choice in high-end paper production. They are very efficient and have a lower impact.
Only substances with low solubility and high dispersibility can be effective defoamers. They must break and suppress foam well. This maximizes their dispersibility. It allows foam suppression and breaking to work together.
A good defoamer should possess the following properties:
1. Strong Defoaming Ability: Requires a small dosage to be effective.
2. Non-Reactive: Does not alter the fundamental properties of the foaming system upon addition.
3. Low Surface Tension: Facilitates effective foam suppression.
4. Good Surface Compatibility: Maintains balance at the surface level.
5. Good Heat Resistance: Remains effective under high temperatures.
6. Excellent Diffusibility and Penetration: Ensures thorough distribution within the system.
7. Chemical Stability: Resistant to oxidation and maintains performance over time.
8. Good Gas Solubility and Permeability: Allows effective gas management.
9. Low Solubility in Foaming Solutions: Minimizes interference in the foaming system.
10. Non-Physiologically Active: High safety and low toxicity for users.
