Description
Vermiculite
With the process of removing sand and impurity, crashing, filtrating, vermiculites become exfoliated, they can be divided into different sizes: 0-1mm, 1-2mm, 2-4mm, 1-3.5mm, 3-5mm, 4-6mm and so on, we can produce many sizes as clients required. There are two kinds of vermiculite in our country golden vermiculite and silvery vermiculite, they have different chemical components.

Expanded vermiculite
Exfoliated vermiculite in the process of high temperature roasting, they can expand many times, and the average density of the expanded vermiculite is about 100-130kg/m3, they have small air separation layer, so they are good construction materials of heat preservation, thermal insulation sound absorption, and corrosion proof, and also industry loading material, coating, anti-fire materials. Expanded vermiculite can extensively used in many industries such as construction, metallurgy, chemical industry, light industry, machinery, electric power, petroleum, environment protection communication, transportation and horticulture.
Main applications:
1.construction materials: light materials such as light concrete materials, light calcimine and light mortar.
2. heat resisting material: wall materials, anti-fire board, anti-fire mortar, firebrick, and brake linings.
3. heat preservation, thermal insulation and sound absorption materials: underground pipeline, heat preservation material used in hothouse pipeline, decoration material used in  upholstery and tunnel, also wall and ceiling in the public.
4.metallurgy: steel frame cladding materials, removal of slag when manufacture of iron and foundry
5. agriculture, forestry and horticulture: golf course lawn, seed preservation agent, soil regulation agent, wetting agent, plant growth agent, feed additives, horticulture mixture, fishing and bait.
6 other aspects: adsorptive material, filter aid, active carrier of chemical and chemical fertilizer, sewage treatment, adsorption of seawater oil pollution, cigarettes filter and explosive density regulators.
Applications and technology indicators of different sizes:
