Expanded vermiculite
Expanded vermiculite is formed by expanding the original ore
vermiculite at a high temperature of *******0 degrees, and the
expansion rate is ***5 times. Expanded vermiculite is a layered
structure with crystal water between the layers. It has a low
thermal conductivity and a bulk density of *****0kg / m3 . The
expanded vermiculite with good quality can be used up to ***0C
. In addition, expanded vermiculite has good electrical
insulation.
Expanded vermiculite is widely used in thermal insulation
materials, fire protection materials, seedlings, planting
flowers, planting trees, friction materials, sealing materials,
electrical insulation materials, coatings, plates, paints,
rubber, refractory materials, hard water softeners, smelting,
construction, shipbuilding, Chemical industry.
