Why is there no silica in the system of methylene white?
Precipitated silica, mainly made up of silica, does no harm to the body. Precipitated silica, also known as light silica, scientific name precipitation, hydrated silica. Is a high-tech inorganic fine chemical products, the main ingredient SiO2.
The performance is similar to that of carbon black. The appearance is white, highly dispersed amorphous powder or flocculent powder, and also processed into granules for commodity. The quality is light, the original particle size is below 0.3 mu m, the relative density is 2.319 to 2.653, the melting point is 1750 DEG C, insoluble in water and most of the acids. It has water absorption, and absorbs moisture in the air, it will become the agglomeration of fine particles. Soluble in hydrofluoric acid and caustic soda. Stable to other chemicals, high temperature, no decomposition, no burning.
The matrix and active ingredients and additives show chemical inertness, and have good compatibility with many active ingredients commonly used in vitamins, hormones, fluorides, antibiotics, enzymes and cosmetics. Having very high electrical insulation. Due to the porous and large specific surface area, the rubber in the greater dispersion of power, fill in the rubber shows high reinforcing. The surface modified hydrophobic white carbon can be easily dissolved in oil, and used as reinforcing filler for rubber and plastic, etc., the mechanical strength and tear resistance index of the product can be remarkably improved. Because of the different manufacturing methods, the physical and chemical properties and microstructure of white carbon will be different, so their application fields and application effects are different.
