Mineral oil defoamer is a kind of classified defoamer, which is mainly named after classification, such as silicone defoamer, polyether defoamer, etc. What is the connection between mineral oil defoamers and mineral oil?The main ingredient of mineral oil defoamer is mineral oil or other oily carriers that are insoluble in the foaming medium, accounting for about 50% to 70%, and mixed with other derivatives to form a defoamer. Due to the good compatibility of the blistering system of mineral oil,Mineral oil defoamerIt can be used in many industrial fields, can eliminate the foam generated in the foaming system, and effectively maintain the normal operation of the industrial production process.

Since mineral oil has such excellent defoaming properties, what is its defoaming principle?Mineral oil defoamers defoam by reducing the surface frying tension, and the mineral oil composition is incompatible with water, so it destroys the integrity of the foam film. Because the mineral oil destroys the fluidity of the foam, when the foam tries to restore the liquid film, it cannot return to its original state, resulting in foam failure.
Mineral oil defoamers are used in a wide range of applications and involve many different industries. In the food industry, mineral oil defoamers ensure the quality and taste of food. In the chemical industry, it can be used as a substitute for surfactants and additives to improve production efficiency and product quality. In addition, mineral oil defoamers are also widely used in coatings, ink adhesives, adhesives and other industries. In textile processing, mineral oil defoamers can improve textile production efficiency and product quality.
Mineral oil defoamers can be used directly or diluted. It can be added after the foam is generated or added to the product as an antifoam component, and the amount of defoamer can be 01~0.3%, the specific usage and details need to be formulated according to the actual needs and uses to develop a detailed plan.
Mineral oil defoamerIt is mainly a defoamer prepared by polymerization of propylene glycol or glycerol with propylene oxide and ethylene oxide under the catalytic action of potassium hydroxide. It is characterized by fast defoaming, strong stability, no color spots and other advantages, which is suitable for most defoaming industries as the needs of defoaming and foam suppression.
