What should I pay attention to when using defoamer for ceramic grouting?

The defoamer for ceramic grouting is a defoamer synthesized from polyether and other components. It is suitable for defoaming under the condition of strong acid and alkali, when the pH value of the defoaming system is 14, many silicone defoamers have broken the emulsion, bleached the oil, and lost the physical state of the defoamer, not only the defoaming power is reduced or disappeared, but also the unexpected drawbacks of the process behind the defoaming product. The defoamer can maintain a good physical state at this temperature, no emulsion, no bleaching, defoaming is stronger than room temperature foam breaking and foaming effect, defoaming is rapid, foam inhibition is long-lasting, and non-toxic, tasteless, will not cause any pollution to the environment, the use of this product defoaming is small, the use of low cost.

Precautions: The amount of addition should not be too much or too little, generally to about 1%.

1. Is the system of defoamer for ceramics suitable for its own system?

First of all, you need to consider whether the system of ceramic defoamer is suitable for your industry. Because ceramic defoamers are oily and water-based, different ceramic defoamers are used in different industries.

Second, you need to consider the amount of alcohol or organic solvent in your system. Because it is the consensus that alcohol has a defoaming effect, there are sometimes some interference effects.

2. The applicable pH range of defoamer for ceramics.

The strong acid and alkali environment has harsh requirements for ceramic defoamers, which requires the carrier environment to be explained with the ceramic defoamer manufacturer.

3. The long-term effect of ceramic defoamer should be considered.

Some ceramics start well with defoamers, but the effect is much worse after a period of time.

There are many influencing factors, at least two reasons:

1) The ceramic defoamer is capacitated by the surfactant, and 2) the main agent of the ceramic defoamer can be absorbed by the colloidal resin.

4. Defoaming ability in static conditions.

When the bubble-producing liquid flows back into the tank or directly into the drum, it can also be defoamed quickly.

Pay attention to the amount of addition, the addition amount of defoamer for general ceramic grouting is the total foaming system, and the specific economic dosage needs to be obtained by actual test.

Pay attention to the addition time, add points, and add amount, which are generally explained by manufacturers.

Defoamers for ceramic slurries are used.

Because it is a defoamer synthesized by polyether and other ingredients. It is suitable for defoaming under the condition of strong acid and alkali, when the pH value of the defoaming system is 14, many silicone defoamers have broken the emulsion, bleached oil, and lost the physical state of the defoamer, not only the defoaming power is reduced or disappeared, but also the unexpected drawbacks of the process behind the defoaming product. This series of defoamers can maintain a good physical state at this temperature, no emulsion, no bleaching, defoaming is stronger than room temperature, this series of products for removing the foam due to anionic surfactant and calcium silicate system, and has good alkali resistance, but also has the advantages of fast defoaming speed and foam inhibition for a long time.

It can solve the foaming problems caused by the ceramic slurry due to the temperature of the production workshop does not meet the requirements, the stirring during production, the inappropriate power of the equipment, the chemical reaction of other additives added, the foaming substances in the raw materials, and the soft water quality.

Ceramic slurry defoamer can be used, which is made of hydrophilically modified polysiloxane and silica through a special process. It is recommended to use concrete and additives first dry mixed and then added to water. The addition of this defoamer will reduce the bubbles of the solution, especially the water-based slurry or mud that contains almost no air, and its defoaming effect is very good.

Ceramic slurry defoamer is a product refined by a special process of organic compounds. In the production, packaging and application of coatings, it controls the generation of foam, has excellent compatibility with a wide range of systems, and is effective over a wide pH range.

In general, this defoamer should be added to one part of the slurry during the grinding stage, and then the other half before the painting stage or sizing stage to achieve a better defoaming effect. If you want to know more about defoamers, you can join the official website of Takata Defoamer.
