The decolorization of oil samples is an important task in the petrochemical industry. Bleaching sand treatment is a common method of oil decolorization, which can effectively remove impurities and pigments in oil products.

Coatings are one of the most important tools in the fight against corrosion. They form a barrier between the metal surface and the environment, thereby reducing oxidation. With increasingly stringent environmental regulations, traditional anti-rust pigments containing heavy metals such as lead, chromium and mercury are gradually being phased out. Silica anti-rust pigments are a type of paint additive whose main component is silicon dioxide (SiO2). They are widely used in the modern coatings industry due to their excellent anti-rust properties and environmental characteristics. This pigment is chemically inert, non-toxic and harmless, and can form a protective layer in corrosive environments, effectively preventing corrosion of metal materials.

Silica printing adsorption media, through its unique physical and chemical properties, such as large pore volume and high purity, can quickly absorb moisture from the ink ejected during the printing process and fix the dye molecules, thereby avoiding color diffusion and mixing and ensuring the quality of the printed image.
