3.Application
Expanded Vermiculite in the process of high temperature roasting, they can
Expand many times, and the average density of the expanded vermiculite is about 900-150kg/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.
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.
4.Package
PP and PE small BAG,12-15KGS/BAG also can put in JUMBO BAGS
5. Storage
Expande Vermiculite must be stored in a cool,dry place .To prevent moisture penetration .packs which have opened should be sealed again as soon as possible.
6.Industrial Safety and Environment Protection
- Risk of explosion by static sparks or ignition sources
- Use only explosion -proof equipment .
