Diatomite is a kind of biogenic siliceous sedimentary rock, which is mainly composed of the remains of ancient diatoms. It is soft, porous and light. The chemical composition of diatomite is mainly SiO2, containing a small amount of Al2O3, Fe2O3, Cao, MgO and organic matter.

1. Paint industry

Furniture, office paint, building (exterior) interior wall paint, machinery, home appliance paint, mimeograph ink, asphalt, automobile paint and other paint fillers.

Advantages of using diatomite: in the coating, the unique porous particle structure of diatomite can make the smooth coating highly rough and produce the light fading effect. Not only that, diatomite can also adjust and balance the adhesion between the coating and the base surface. In addition, due to the porosity of diatomite, the viscous paint can be dried quickly. Neutral pH value, non-toxic, fineness of 120 mesh to 1200 mesh, light and soft constitution, it is a high-quality filler in paint.

2. Special for centrifugal casting (pipe) coating

The centrifugal casting (pipe) coating prepared with diatomite, binder, suspending agent and additive treated by appropriate process can adjust the thermal resistance of the casting system and control the cooling rate of the casting (pipe), so as to prolong the service life of the mold used in the hot mold centrifugal casting and ensure that the metallographic structure and mechanical properties of the casting meet the requirements

3. Thermal insulation industry

Roof thermal insulation layer, thermal insulation brick, calcium silicate thermal insulation material, porous coal cake furnace, thermal insulation material, sound insulation and fireproof decorative board and other thermal insulation, heat insulation and sound insulation building materials.

Advantages of using diatomite: diatomite is the best raw material for non-metallic heat insulation, sound insulation and heat preservation. Its fire resistance can reach 1380 ℃. It can play the role of heat and sound insulation, smooth, soft and high compressive strength.

4. Rubber industry

Rubber products, rubber belts, rubber belts for vehicles, etc.

Advantages of using diatomite: the unique particle structure of diatomite can make it act as semi reinforcing material in products such as silicone rubber and mechanical rubber, and can partially replace carbon black. It can obviously enhance the rigidity and strength of the filling system, the settlement volume is up to 95%, and can improve the chemical resistance of products such as heat resistance, wear resistance, heat preservation and anti-aging.

5. Plastics industry

Domestic plastic products, building plastic products, agricultural plastics, window and door plastics, various plastic pipes, and other light and heavy industrial plastic products.

Advantages of diatomite: it has excellent extensibility, strong impact strength, tear strength, light weight, soft body, good wear resistance, excellent compressive strength and other high-quality functions.

6. Water treatment and other industries

Porosity and adsorption are used as adsorbents in water treatment to treat sewage, etc.
