Vermiculite explain
Vermiculite is a layered structure containing magnesium silicate secondary metamorphic minerals water aluminum ore outside, like mica, usually by black (golden) mica by hydrothermal altered effects or weathering and become, because its heated dehydrate expands is flexing shape, form resembles leeches, therefore calls vermiculite.
Vermiculite of patent for (Mg, Ca) 0.7 (Mg, Fe, Al [(Al) 6.0, Si) 8.0] (OH4.8 H2O)
Vermiculite by phases is divided into ShiYuan intercalated ore deposits and expanded vermiculite, color-coded classification can be divided into golden vermiculite, silvery white vermiculite. Ivory vermiculite.
I plant production configurations of high-temperature roasting ShiYuan ore can rapidly expanding its volume 8-20 times, expand the proportion of 130 - after 180kg/m3. In fire prevention insulation good thermal insulating properties.
