Fatty Alcohol Defoamer
Fatty alcohol defoamer are non-silicone products which can remove the bubbles contained in the slurry and white water(the papermaking wet-end), improve the dehydration on the web. so sometimes, we called it deaerator or alcohol based antifoams
Fatty alcohol defoamers do not impact the sizing effect in pulp, unlike other antifoaming agents used in papermaking. This makes them particularly suitable for the production process of special papers that involve numerous additives, such as wet strength agents and internal sizing agents. Fatty alcohol defoamers exhibit excellent extensibility in water, disperse easily, and can effectively enhance the dehydration conditions of the mesh. Additionally, they help reduce deposits caused by foam, ensuring a smoother and more efficient production process.

Fatty alcohol Defoamer Test Comparison Result in White Water of Papermaking
Instrumentation
- Cyclic Bubbling Instrument: Used to simulate the papermaking white water system.
- White Water Source: Collected from under a cattle cardboard
Defoamer Samples : INVINO-5045 , Customer sample 1#, 2#,3#
Test Method
- Preparation: Prepare a 500 mL measuring cylinder and add 200 mL of white water. Maintain the water temperature at 45°C during the entire testing process.
- Bubbling Process: Start the bubbling until the foam volume reaches 250 mL.
- Defoamer Application: Add one drop of the defoamer sample into the measuring cylinder.
- Observation and Measurement: Observe whether the foam is removed after defoamer addition. Record the time taken for the foam to change to successive volumes (e.g., 250 mL, 300 mL, 350 mL, 400 mL, etc.).
Notes:
- Ensure consistent temperature control for reliable test results.
- Follow the specified intervals for recording foam volume changes to accurately evaluate defoamer performance.
