Diatomite is a kind of siliceous rock. Diatomite is composed of amorphous SiO2 and contains a small amount of Fe2O3, CaO, MgO, Al2O3 and organic impurities. The advantages of diatomite application: 1: neutral pH value, non-toxic, good suspension performance, strong adsorption performance, light bulk weight, 2: diatomite should be used as an additive in cement, 3: excellent extensibility, high impact strength, tensile strength, tear strength, light and soft internal grinding, good compressive strength, etc. The advantages of diatomite application: neutral pH value, non-toxic, fineness 120 to 1200 mesh, It is light and soft, and is a high-quality filler in paint. Feed industry: additives for pigs, chickens, ducks, geese, fish, birds, aquatic products and other feeds. The application of diatomite has the advantages of 5: strong sun protection, soft and light constitution, and high-quality fillers that can eliminate leather pollution of balloon products: light capacity, neutral PH value, non-toxic, soft and smooth powder, good strength performance, sun protection and high temperature resistance. Diatomite is used in coating, paint, sewage treatment and other industries. Diatomite coating additive products have the characteristics of large porosity, strong absorption, chemical stability, wear resistance, heat resistance, etc., which can provide excellent surface performance, compatibilization, thickening and improving adhesion for the coating. 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 the cost. This product is considered to be a kind of high-efficient paint matting powder with good cost performance. It has been widely used in water-based diatom mud as a designated product by many large paint manufacturers in the world.
