Defoamer ( Defoaming Agent )

Defoamer is an auxiliary agent, and its function is to eliminate the foam formed by materials during the production process. The main component of organic silicon defoamer is silicone oil, which is a non-volatile oily liquid at room temperature. It is insoluble or has very low solubility in water, animal and vegetable oils and mineral oils. It can withstand both high and low temperatures. It is chemically inert, physically stable, and has no biological activity.

Product Application

01

Defoamer for Wall Putty

The role of defoamer in wall putty is crucial, it can significantly improve the quality and effect of putty powder, ensure the smooth progress of construction, and the final beauty and durability of the wall.
02

Defoamer for Mortar

It can effectively reduce the gas content of wet mortar, increase the wet density of mortar, so as to significantly improve the physical properties of mortar, and improve the compressive and flexural strength and tensile bond strength of mortar to varying degrees.

03

Defoamer for Detergents

Defoamer are added in certain types of detergents to reduce foaming that might decrease the action of the detergent.

Production Process

The production process of defoamer mainly includes three steps: raw material preparation, reaction system configuration, reaction and process control.

1.‌Raw material preparation‌:
First, the main raw materials need to be prepared, including dimethyl silicone oil, hydroxy silicone oil, silicon dioxide, fatty amine polyoxyethylene ether, thickener, hydrocarbonized oil, emulsifier, etc. These raw materials play different roles in the production process, such as defoaming, thickening, stabilization, etc.

2.‌Mixing and stirring‌:
Add the prepared raw materials to the reactor in a certain proportion, and stir them at an appropriate speed through the agitator to ensure that the raw materials are evenly mixed.

3.‌Heating and reaction‌:
Heat the reactor to a certain temperature, usually between 100-135°C, and keep it for a certain time to promote the chemical reaction between the raw materials. In this process, promoters, stabilizers and other additives can be added as needed to control the reaction rate and product quality.

4.‌Preparation and purification‌:
After the reaction is completed, preparation and purification are carried out through distillation, washing, filtration and other steps to remove unreacted raw materials and by-products to obtain pure organosilicon solid defoamer.

5.‌Packaging‌:
Finally, the purified organosilicon solid defoamer is packaged for easy storage and transportation
