Raw vermiculite &Expaned 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. E xpanded 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.
