Diatomite, due to its unique physical and chemical properties, has been widely used as a filter aid, functional filler, catalyst carrier, pesticide and fertilizer carrier, thermal insulation material, adsorbent, and bleaching material, among others.
Specific Uses
1.Diatomite is mainly used as a thermal insulation material, chemical filler, and catalyst carrier.
2.Diatomite is used as a filter agent for synthetic resins, chemical fibers, dyes, coatings, solvents, acids, electrolytes, glycerol, etc.; a carrier for chemical fertilizers and pesticides; an ideal filler for plastics, rubber, and insecticides; a filter aid for sodium thiocyanate recovery; activated carbon for decolorization in nylon solutions; and an anti-caking agent for ammonium nitrate pellets. It is also widely used in sectors such as light industry, food, pharmaceuticals, building materials, petroleum, papermaking, and environmental protection. Diatomite has broad development prospects.
3.It is used for the processing and beneficiation of diatomite ores.
