Diatomaceous earth powder food grade, which can be used to diatomaceous earth filter, food grade oil so on.
| Diatomaceous earth is composed of amorphous SiO2, and contains a small amount of Fe2O3, CaO, MgO, Al2O3 and organic impurities. Diatomaceous earth is usually light yellow or light gray, soft, porous and light. It is commonly used in industry as insulation materials, filter materials, fillers, abrasive materials, water glass raw materials, decolorizers, diatomite filter aids, and catalyst carriers. Wait. The main component of natural diatomaceous earth is SiO2, high-quality ones are white, and the content of SiO2 often exceeds 70%. Monomer diatoms are colorless and transparent. The color of diatomaceous earth depends on clay minerals and organic matter. The composition of diatomaceous earth from different mineral sources is different. Diatomite paint additive products have the characteristics of large porosity, strong absorption, stable chemical properties, wear resistance, heat resistance, etc., which can provide coatings with excellent surface properties, compatibilization, thickening and improving adhesion. Because of its large pore volume, it can shorten the drying time of the coating film. It can also reduce the amount of resin and reduce costs. This product is considered to be a high-efficiency matting powder product with a good cost performance. It has been designated by many large-scale coating manufacturers in the world and is widely used in water-based diatom mud.
