Application of food grade defoaming agent
Silica gel defoamer is made of ether, fatty alcohol and various active additives through a special process. Its main function is to defoam and suppress foam. Because of its low surface tension and good diffusion performance, it can spread quickly on the surface of the solution, so it can quickly break the foam that has appeared; at the same time, because of its good permeability, it exists in the form of particles in the foaming system, And continuously destroy the elastic membrane of the bubbles, thus preventing the generation of foam for a long time.
According to the physical state of its existence, silica gel can be divided into two types: liquid silica gel and solid silica gel. When silicone defoaming agent is applied to these two materials, its excellent effects are also reflected.
1. Liquid silicone is generally used in baby products, kitchen supplies and medical supplies. It is an environmentally friendly food-grade material. For the foam produced by such materials, silicone defoamer can achieve good defoaming and foam suppression effects while ensuring its environmental protection. There is no need to worry about the residue of harmful substances, and its heat resistance is good. In liquid silicone When cured at high temperature, it will not have any impact on the defoaming performance.
2. Solid silicone is also a transparent and environmentally friendly material, but it is different from liquid silicone in that it needs to add a vulcanizing agent during molding to speed up the molding time, and it must be molded by a press and then placed in a mold for molding. Silicone defoamer has stable chemical properties and is not easy to react with other additives. It is acid and alkali resistant and non-volatile. It can maintain excellent defoaming and suppression effects under harsh conditions, will not cause residue on the mold, and is easy to clean equipment tools. It will not cause shrinkage or hole expansion to the product during molding, and will not affect the aesthetics of the product.
Wide range of applications: Silicone food-grade defoaming agents are suitable for various food processing industries, such as fermentation, beverages, dairy products, cooking, baking, etc., and can also be used in other fields such as biomedicine, coatings, petrochemicals, papermaking, and industrial cleaning.
Stability: Silicone food-grade defoaming agent has good stability and can still maintain good defoaming performance in harsh environments such as high temperature, strong acid, and strong alkali.
Easy to use: Silicone food-grade defoaming agents can be widely used in liquid, semi-solid, solid and other food raw materials and products. The method of use is simple and can generally be applied by adding, spraying, pumping, etc.
