Defoamers play an important role in industrial production and daily life. With the advancement of technology, non-silicone defoamers have played their "non-silicone" advantages in solving foam problems and have gradually become the focus of market attention. This article will take you to an in-depth understanding of the application knowledge of non-silicone defoamers.

1. What is a non-silicone defoamer

Non-silicone defoamer is a defoamer that does not contain silicone ingredients. It can quickly disperse foam and prevent it from agglomerating. Through emulsification, the gas in the foam is dispersed into the liquid to eliminate the foam. Compared with traditional silicon-based defoamers, non-silicon defoamers generally have better biodegradability and lower environmental impact. Many non-silicone defoamer ingredients are derived from natural or renewable resources, and use ingredients such as polyether and polyester to overcome the limitations of silicone-based defoamers and reduce the burden on the environment. Applicable to a wider range of scenarios.

2. What are non-silicon defoamers?

Non-silicon defoamers can be divided into many types according to their ingredients, and their characteristics include:

• Polyethers: Polyether compounds have good dispersibility and stability, can be evenly distributed in liquids, and effectively prevent the generation and growth of foam. Suitable for high temperature environments, and often used in neutral or alkaline systems, such as foam control in industrial processes such as papermaking, textiles, printing, and dyeing.

• Polyesters: Based on polyester resins, they have excellent defoaming effects, show better defoaming performance under acidic conditions, and are suitable for complex environments.

• Plant oil-based: Natural extracts, high safety, good biodegradability, suitable for food and cosmetics industries.

3. The role of non-silicon defoamers

Non-silicon defoamers have excellent defoaming effects, can quickly disperse foam, prevent it from agglomerating and spreading, and thus improve the efficiency of the process. Not only that, it can also prevent foam regeneration, avoiding production interruptions or quality problems caused by repeated foam generation. For example, in the fields of chemical, pharmaceutical, and food processing, foam problems may cause product turbidity or performance degradation. Non-silicon defoamers ensure product stability and consistency by eliminating foam.

4. How to use non-silicon defoamers

• Dilution: Non-silicon defoamers usually need to be diluted before use, generally around 50-300ppm. The dilution ratio depends on the specific application scenario and the severity of the foam.

• Addition: Add the diluted non-silicon defoamer directly to the liquid that needs to be defoamed. It is recommended to add it under stirring or circulation conditions to ensure uniform distribution.

• Continuous use: Non-silicon defoamers can be added continuously during the process of defoaming, or preventively before foam is generated.

Non-silicon defoamers are gradually becoming the new favorite of the market due to their environmental protection, biodegradability and wide applicability. Whether it is polyether, polyester or vegetable oil-based, each non-silicon defoamer has its unique performance and application scenarios.
