Organosilicon 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 non silicone defoamer which is completely free of organic silicon and belongs to high carbon alcohol ether emulsion. It is mainly produced by special process of hydrocarbon, high alcohol and esterification. Use difference: non silicon defoamer is mainly used in papermaking industry and other industries that cannot use silicone defoamer. Silicone defoamer is suitable for defoaming of industrial circulating water, water treatment, circuit board cleaning, metal cutting fluid, metal cleaning, oil processing grinding fluid and alkaline cleaning fluid. It is suitable for defoaming in textile, printing and dyeing, emulsion polymerization, Civil washing, all kinds of colorants and low grade paints.            Silicone defoamer is an assistant. Its function is to eliminate foam formed in the process of production. Silicone organic silicon defoamer is the main component of silicone oil, which is called silicone oil. Silicone oil is nonvolatile oil at room temperature. It is insoluble in water, animal and vegetable oils and mineral oil, or has little solubility. It can resist high temperature and low temperature. 。 Chemical property is inert, physical property is stable, no biological activity.            The reason why organosilicon defoamer can't be completely dissolved in water is that it has poor water solubility. Some floccules may be poor alkali and acid resistance, or poor water solubility. Yuheng chemical's organosilicon defoamer is a biological inert defoamer refined by special process with modified polysiloxane as the main component, non-toxic food grade emulsifier, dispersant and stabilizer. The characteristics are: excellent water solubility, stable emulsion, excellent anti foaming ability, strong alkali resistance and low dosage. It can be widely used in metal cutting fluid, metal cleaning, oil processing grinding fluid and alkaline cleaning liquid. It is suitable for defoaming in textile, printing and dyeing, emulsion polymerization, Civil washing, all kinds of colorants and low grade paints. It is suitable for industrial circulating water, water treatment, environmental treatment and other water phase defoaming.            Defoamer products can be used directly or after dilution. If it can be fully stirred and dispersed in the foaming system, it can be added directly without dilution. If dilution is needed, follow the dilution method in the attachment. The method of directly diluting the product with water is not suitable, and it is easy to break the emulsion layer by layer, which affects the quality of the product. The company shall not be liable for the consequences caused by the direct dilution of water or other incorrect methods of processing or using products.            Silicone defoamer is a white viscous emulsion. It has been used in various industrial fields since the 1960s, but the large-scale and comprehensive rapid development began in the 1980s. As organosilicon defoamer, its application field is also very wide, more and more attention by all walks of life. Silicone defoamer is an indispensable assistant in the chemical industry, papermaking, coating, food, textile and pharmaceutical industries. It can not only remove froth on the liquid surface of the process medium, but also improve the separation, gasification, drainage and other effects of filtration, washing, extraction, distillation, evaporation, dehydration, drying, and so on, and ensure that all kinds of materials are flourishing. The capacity of the container.            An excellent defoamer must take into account both the elimination and the foam suppression. That is, not only should the foam be destroyed quickly, but also the foam can be prevented for a long time. The reason for this may be related to whether the critical micelle concentration of foaming agent (surfactant) in solution exceeds. In the excess solution, defoamer (generally organic liquid) may be solubilized, so as to lose the effect of spreading on the surface, and the defoaming effect will be greatly reduced. After a period of time, as defoamer is gradually solubilized, defoaming effect is correspondingly weakened.            Recommended for you: Digo Airex 901w (polyether siloxane copolymer, suitable for high viscosity preparations, eliminating microbubbles), df-888 (silicon free, fluorine free, ape free, is a special structure of high-performance water-based defoamer, which has the characteristics of long-lasting defoaming, efficient removal of microbubbles, etc.)
