Exfoliate Golden Vermiculite

Product Description

Vermiculite brief
1, Brief introduction
The mineral name of the vermiculite is from Latin, which means " worm's form " or "worm's shape". Chinese calls vermiculite the crooked mineral as leech. It is uncertain which chemical composition (Mg, Fe, AL) 3 [(Si'AL)4O10(OH)2].4H2O. The monocline crystal, usually take the form of flake. Brown, yellowish-brown or bronze-colored. Oil gloss. Hardness 1~1.5. Density 2.4~2.7g/cm3, the shape of the vermiculite has two kinds, the thick one is mostly transformed by black mica, etc. keeping the characteristic of mica shape or squama shape; The thin one takes the form of soil, it is so difficult to distinguish which mixed with other clay mineral, the vermiculite is roasted for 0.5~1.0 minutes at 800~1000 c, the volume swells rapidly, increase 8~15 times, the high one can be up to 30 times. Exfoliate vermiculite average unit weight for 100~130Kg/m3, because of roast, expanded vermiculite have tiny air interlayer, so have the function of fine warm-keeping performance..

3, Use and function:
After roasting, the weight of vermiculite to be light and have the performance of freezing, keeping warm, insulating against heat, sucking sound, and it mainly used in industries extensively such as the building, electricity, petroleum, chemical industry, metallurgy, textile, agriculture and food, etc. Used for insulating against heat, sound insulation and covering materials with paint on the construction,. For agriculture , improving the soil, the adjuvants of chemical fertilizers carriers, materials carriers such as animal's feed, deodorant, domestic animal medicine, pesticide,etc., can also make insecticide, bactericide, disinfectant, organic compound (purlin brain) formates pharmaceutical, and in order to store vegetables and other scarce plants roots, good intermediaries of the stem, leaf. The vermiculite has performance of absorbing to the radioactive element, still can deal with the waste water of some radioactive elements.
