Organic silicon solid defoaming powder

Abstract

The invention provides an organic silicon solid defoaming powder, comprising the following ingredients in percentage by weight: 3-4 modified simethicone, 2.5-3.2 methoxy and ethoxy silicone oil, 1.9-2.2 hydroxyl silicone oil and 1 dispersant. The defoaming powder has good defoaming and foam inhibition properties, can be used for eliminating water-phase foam in the production process of industries of cleaning, chemical technology, water treatment, paper making, and the like, can also be used as a foam inhibition ingredient in various printing and dyeing, water treatment, cleaning, cosmetic aids and mechanical aids, and is especially and suitably used as a defoaming and foam inhibition component in a high-alkaline cleaner for beer bottles, baby bottles, and the like.

Description

technical field [0001] The invention relates to the field of defoamers, more specifically, the invention relates to a solid silicone defoaming powder. Background technique [0002] In daily life and production, sometimes the appearance of foam will bring a lot of inconvenience to people, so it must be defoamed. All factors that can destroy the stability of the foam can be used for defoaming. General physical defoaming methods are difficult to defoam instantly, but chemical and interface defoaming are very fast, convenient and efficient. In a nutshell, defoamers refer to agents that have chemical and interfacial chemical defoaming effects. Defoaming covers the two factors of "foam suppression" and "foam breaking". Silicone defoamer is endowed with this function. It can reduce the surface tension of water, solution, suspension, etc., prevent the formation of foam, or reduce the original foam , usually with a selective effect. [0003] When silicone is added to the foam med...

Problems solved by technology

[0004] At present, silicone defoamers can be divided into four categories: oil type, silicone oil solution type, emulsion type and solid type. Traditional defoamers exist in liquid form, and most of them are milky white viscous liquids. Therefore, when used in wastewater When processing, the following problems are prone to occur: first, the viscous nature of the defoamer itself can easily cause the pipeline blockage of the dosing pump or related equipment, so that the operators of the waste water treatment plant need to clean it frequently; second, due to the general There is usually a certain distance or elevation difference between the sewage treatment facilities and the discharge port. In order to avoid the failure of the defoamer, it is often necessary to increase the dosage or use a more expensive long-acting defoamer, which makes the defoaming effect difficult to control. In addition, the operating costs of waste water treatment plants have increased
