Silicone defoameris a very popular defoamer because it has unique advantages in the field of defoaming and strong defoaming ability. This is the main reason. Secondly, it has a wide range of applications. It has the advantages of low surface tension, good thermal stability, good chemical stability, and physiological inertness. It can be used in a wide range of defoaming applications, so many industries like to use silicone defoaming agents, but how can it be called a good silicone defoaming agent? How should we choose when we choose? Now Xianrenhui Chemical will give you a brief introduction.
Silicone type defoamerThe main component is called silicone oil. Silicone oil is an oily liquid that does not evaporate at room temperature. It is insoluble in water, animal and vegetable oils and mineral oils, or has very little solubility. It can withstand high temperatures and also Able to use low temperature. It has low chemical properties, stable physical properties, no biological activity, no pollution, and no harm to the environment, so it can be used in most industries, such as water treatment industry, metal processing industry, and even in food Silicone defoamer can also be used in professions.
There is no doubt that silicone defoamer can be used in many industries, but not one silicone defoamer can be used in all industries. When selecting a silicone defoamer, you must first consider occupational factors and determine the corresponding occupation of the silicone defoamer. Then consider the foaming system of the foaming liquid, such as pH value, temperature, compatibility, etc. It is necessary to consider that the selected defoaming agent can be effective in the environment of foaming liquid before selection. Then study the differences between different brands of silicone defoamer based on the brand, such as usage amount and effects. After determining the selected defoaming agent, you can contact the relevant customer service to inquire whether it is possible to test samples. After passing the samples, it is very suitable to select a very useful product for purchase.
Organic silicone defoaming agent not only has strong defoaming ability, but also has the characteristic of low dosage. Its general application range is 1 to 100ppm, and only needs One millionth of the foaming medium content can play a defoaming effect, which is not only low cost, but also does not pollute the material being defoamed.
The above is Xianrenhui Chemical’s introduction on how to choose a suitable silicone defoamer, I hope it can help you.
