Let's talk about it today silicone defoamer ; when will it be added? Note what should be added before! What is the difference between silicone defoamer and non silicone defoamer? Use and difference? The selection of defoamer should be based on the following points?

Two conventional adding methods of Dongguan silicone defoamer?

1. Add before foaming

This method can inhibit the production of foam by adding defoamer to the system that may produce foam. Both the antifoaming agent and the closed container can effectively eliminate foam.

2

In the case of continuous defoaming agent, the circulating defoaming agent can also be used to achieve the best effect in the case of circulating defoamer.

Note before adding!

First, the emulsion needs to be fully stirred before use.

Because the uneven emulsion will easily cause delamination and affect the use effect of defoamer.

Second, try to use thickener for thinning.

If the dilution agent is used up, it is recommended to use the defoaming agent when the dilution agent is used up.

Third, prevent frost and high temperature.

Silicone defoamer is sensitive to frost and high temperature and easy to be damaged. If the defoamer has been frozen, be careful to remove the frost and test before use.

Fourth, pay attention to the storage of silicone defoamer.

Therefore, the use of strong defoamer or defoaming agent for long time will destroy the stability of mechanical foam remover.

What is the difference between silicone defoamer and non silicone defoamer?

Silicone defoamer is a kind of bio inert defoamer, which is mainly composed of modified polysiloxane, non-toxic food grade emulsifier, dispersant and stabilizer, and refined by special process.

Non silicon defoamer is a kind of high carbon alcohol ether emulsion non silicon defoamer without organic silicon. It is mainly produced by special process of hydrocarbon, high carbon alcohol and esterification.

Dongguan silicone defoamer Use and difference?

Non silicon defoamer is mainly used in paper industry and other industries that can not use silicone defoamer.

Silicone defoamer is suitable for industrial circulating water, water treatment, circuit board cleaning, metal cutting fluid, metal cleaning, oil processing grinding fluid, alkaline cleaning fluid. It is suitable for defoaming of textile, printing and dyeing, emulsion polymerization, Civil washing, all kinds of color paste and low-grade coatings.

The selection of organic defoamer should be based on the following points?

1. It is insoluble or insoluble in foaming solution;

2. The surface tension is lower than that of foaming solution;

3. It has a certain degree of affinity with foaming fluid;

4. There is no chemical reaction with foaming solution;

5. Low volatility and long action time.
