Diatomite is a kind of siliceous rock and a biogenic siliceous sedimentary rock. It is mainly composed of the remains of ancient diatoms. Its chemical composition is mainly SiO2, which can be expressed by SiO2 · nH2O, and its mineral composition is Opal and its variants. China's Diatomite reserves are 320 million tons and the prospective reserves are more than 2 billion tons. It is mainly concentrated in East China and Northeast China, of which Jilin, Zhejiang, Yunnan, Shandong, Sichuan and other provinces have large scale and large reserves.

Agricultural and pharmaceutical industry: wettable powder, dryland herbicide, paddy field herbicide and various biological pesticides. Advantages of diatomite: neutral pH value, non-toxic, good suspension performance, strong adsorption performance, light bulk weight, oil absorption rate of 115%, fineness of 325 mesh - 500 mesh, good mixing uniformity, no blockage of agricultural machinery pipeline, moisturizing in the soil, loosening the soil, prolonging the efficacy and fertilizer effect time, and promoting the growth of crops.

Compound fertilizer industry: compound fertilizer for various crops such as fruits, trees, vegetables, flowers and plants. Advantages of diatomite: strong adsorption performance, light bulk density, uniform fineness, neutral pH value, non-toxic and good mixing uniformity. Diatomite can become a high-efficiency fertilizer, promote crop growth and improve soil.

Rubber industry: fillers in various rubber products such as vehicle tires, rubber pipes, V-belts, rubber rolling, conveyor belts, automobile footmats, etc. The advantage of diatomite is that it can obviously enhance the rigidity and strength of the products, and the settlement volume is up to 95%. It can also improve the chemical properties of the products such as heat resistance, wear resistance, heat preservation and anti-aging.

Building thermal insulation industry: roof thermal insulation layer, thermal insulation brick, calcium silicate thermal insulation material, porous coal cake furnace, sound insulation and fireproof decorative board and other thermal insulation, heat insulation and sound insulation building materials, wall sound insulation decorative board, floor tile, ceramic products, etc; Advantages of using diatomite: diatomite should be used as an additive in cement. Adding 5% diatomite in the production of cement can improve the strength ZMP, and the SiO2 activity in cement can be used as emergency cement.

Plastic industry: living plastic products, building plastic products, agricultural plastics, window and door plastics, various plastic pipes, other light and heavy industrial plastic products. Advantages of using diatomite: excellent extensibility, high impact strength, tensile strength, tear strength, light and soft, good internal abrasion, good high pressure strength and so on.

Paint and coating industry: furniture, office paint, architectural paint, machinery, home appliance paint, mimeograph ink, asphalt meter, automobile paint and other paint and coating fillers; Advantages of diatomite: neutral pH value, non-toxic, fineness of 120 mesh to 1200 mesh, light and soft constitution, belonging to the filler in paint.

Leather and artificial leather industry: artificial leather products and other leather. Advantages of diatomite: strong sunscreen, soft and light constitution, and can eliminate leather pollution.

High quality packing of balloon products: light capacity, neutral pH value, non-toxic, light, soft and smooth powder, good strength performance, sun protection and high temperature resistance.
