Vermiculite
    I plant specialized in the production of fire insulation materials dedicated vermiculite, the main models are :1-3mm scholar-4mm. 10-20 head ,20-40 head ,40-60 ,80 Head-120 etc..
    Vermiculite series :  Vermiculite golden yellow, silver and white vermiculite, such as vermiculite slate
    Vermiculite note
    Vermiculite is a layered structure of the magnesium aluminum silicate secondary water metamorphic minerals, ore outside like mica, usually black (DRC) by hydrothermal biotite alteration or winds, because the heat was dehydrating inflates deflection form shape resembles leeches, it said vermiculite.
Vermiculite the chemical formula for （Mg，Ca）0.7（Mg，Fe，Al）6.0[（Al，Si）8.0]（OH4.8H2O）
    Vermiculite is divided into stages by the vermiculite ore and expanded vermiculite, according to the color separation can be divided into golden vermiculite, silvery white vermiculite. Milky white vermiculite.
    I plant the vermiculite ore after baking volume can be quickly expanded 8 -20 times. After expanding the proportion of 130 -180kg/m3. Fire in the insulation with good thermal insulation properties.

According to the internal crystalline water content in different areas into obsidian, perlite Perlite is to smash the magmatic rocks heated to 1000 ° C to form the above expansion, with a closed porous structure, Particle diameter is generally 0.5 ~ 2.5mm between. Light, good ventilation, no nutritional elements. In the use of floating easily in mixed ...
