Silicone defoamer

Organosilicon defoamer is a widely used defoamer in multiple industrial fields. The following is a detailed introduction about it:

1. Definition and Composition

• definitionOrganic silicon defoamer is an auxiliary agent used to eliminate foam formation of materials in the production process.

• Main componentsIts main components are silicone oil and organic silicon components, which are non-volatile, oily liquids at room temperature and insoluble or have a solubility lower than water, animal and vegetable oils, and mineral oils.

2. Characteristics

• Chemical and Physical Properties：

• Chemical inertness.

• Stable physical performance.

• No biological activity.

• Capable of withstanding both high and low temperatures.

• form: Silicone defoamer is a white viscous lotion.

3. Application Fields

• The application fields of organosilicon defoamers are very wide, including but not limited to the following industries:

• Chemical industry: used in the production process of polymers to improve product quality.

• Pharmaceutical field: control the foam and bubble of drugs to improve pharmaceutical efficiency.

• In the field of food processing: used for candies, bread, fried foods, etc., to prevent food from losing its texture due to bubbles.

• Washing products: reduce the production of foam and bubbles, and enhance the cleaning effect.

4. Working principle

• The working principle of defoamer is to destroy and inhibit the formation of foam. Specifically, the defoamer enters the bimolecular directional film of foam and destroys the mechanical balance of the directional film, thus achieving the effect of foam breaking.

• Defoamer is a substance that is insoluble in foaming media and can be dispersed into the foaming medium in the form of droplets, droplets wrapped around solid particles, or solid particles.

• The faster the defoamer spreads on the solution surface, the thinner the liquid film will become, the faster the foam will be destroyed, and the defoaming effect will be strengthened.

5. Formula and Preparation

• The formula for silicone defoamers may include ingredients such as methylsiloxane oil, sodium tripolyphosphate, salt, mannitol, and silica.

• The preparation process may involve steps such as mixing, esterification, emulsification, etc. of various components under specific conditions.

6. Safety and Environmental Protection

• When using, pay attention to its safety and avoid contact with the skin and inhalation of its vapor.

• In the production and application process, it is necessary to pay attention to reducing the generation of hazardous waste and ensuring the environmental friendliness of the production process.

7. Conclusion

Organic silicon defoamer, as a versatile defoamer, has a wide range of applications in various industrial fields. Its unique chemical and physical properties, as well as excellent defoaming effect, make it one of the indispensable additives in industrial production.
