Organic fluorine

Organic fluorine defoamers are a type of chemical additive with excellent defoaming performance, widely used in multiple industrial fields. The following is a detailed introduction to organic fluorine defoamers:

Definition and Overview

definition：Organic fluorine defoamer is an organic compound containing fluorine element. Through its special molecular structure and chemical properties, it can rapidly reduce the surface tension in liquid, destroy the foam structure, and achieve defoaming effect.

Types and characteristics

1. Fluorosilicon defoamer：

• Ingredients: Fluorosilicone defoamer is a compound of foam breaking polymer and organic silicon fluorocarbon.

• Characteristics: It has strong defoaming and anti foaming properties, stable chemical properties, is not easily reacted with foaming media, is not easily volatile, and will not affect the basic properties of raw materials.

• Application: Suitable for industries such as fluorosilicone, oil-based coating systems, and epoxy resins.

2. Fluorine modified defoamer：

• Ingredients: Fluorine modified defoamer is compounded by a special process.

• Characteristics: easy to disperse in water, fast defoaming speed, long foam suppression time, and no secondary foam.

• Application: Suitable for the manufacturing process of various adhesives, as well as products in the paper industry and metalworking fluids.

3. Fluorosilicone resin defoamer：

• Ingredients: Made from organic silicon fluorocarbon as raw material through special processing and compounding.

• Characteristics: The defoaming speed is rapid, which can effectively inhibit the production of secondary foam. It can also continue to conduct defoaming and foam suppression under high temperature and pressure, strong acid and alkali.

advantage

1. Excellent defoaming effect：Organic fluorine defoamer can quickly and effectively eliminate foam in liquid and ensure the quality of materials in application.

2. Good stability：Maintain its defoaming effect over a wide temperature range and do not decompose into harmful substances in the material.

3. Wide applicability：Suitable for various industrial fields, such as coatings, inks, adhesives, rubber products, plastic products, etc.

shortcoming

1. High price：Due to the high technical and process requirements in the production process, as well as its unique composition, the price of organic fluorine defoamers is relatively high.

2. Has a certain impact on the environment：The fluorine element emitted during use may have a certain impact on the environment, and attention should be paid to environmental protection issues.

3. May have an impact on the human body：Fluorine may have an impact on the human body at certain doses, so safety should be taken into account when using it.

Precautions for use

1. Stir thoroughly：Before use, the defoamer should be thoroughly stirred to ensure even distribution in the liquid.

2. Suitable addition amount：Determine the appropriate amount of additives based on production needs and system characteristics to avoid excessive use.

3. Pay attention to storage conditions：Store in a dry, cool, ventilated place, away from direct sunlight and high temperature environment.

conclusion

Organic fluorine defoamers have become indispensable additives in modern industrial production due to their excellent defoaming performance and wide application fields. By reasonable use and management, its defoaming performance can be fully utilized to meet various application needs.
