Vermiculite is a layered structure, the interlayer crystal water, swelling in 5-25 times, small thermal conductivity, bulk density 50-200kg / m3, is good insulation. Good quality expanded vermiculite, the maximum temperature up to 1100 ℃. In addition, the expanded vermiculite has good electrical insulation properties.
Vermiculite has a thermal conductivity of small, lightweight noise insulation, fire and other water features.Can withstand repeated freezing and thawing without alternately bad, bulk density at -300C, the same strength, not deformed, not rot, not bad, not moth-eaten. Vermiculite also has characteristics not acid and alkali.
Vermiculite uses:
1, as a lightweight material. Vermiculite do lightweight concrete aggregate, lightweight wall pellets, light mortar and roofing boards, bricks and other guns used in high-rise buildings.
2, vermiculite can be used for insulation, heat insulation, sound-absorbing material.
3, due to the large porosity of vermiculite, vermiculite do soil conditioner in agriculture, horticulture, improvement of soil;
In the metallurgical industry can be made of refractory bricks, masonry system smelting furnace lid.Vermiculite can absorb the sea, Hanoi oil. Prevented some radioactive contamination, the protective effect. Vermiculite in the feed industry is the production of antioxidants, adsorbents, preservatives, raw materials, mineral trace elements do feed carrier, vermiculite also inhibit the growth of mold, anti-virus effect, do mildew.
