Introduction of Vermiculite Board：
Vermiculite board is made of high-quality vermiculite ore after 900 ° C - 1000 ° C high-temperature expansion of worm-like expanded vermiculite (expanded vermiculite is a lightweight thermal insulation and fireproofing materials), inorganic auxiliary materials and adhesives in accordance with a certain ratio of mixing, put into the grinding machine, through the pressure molding, low-temperature maintenance, high-temperature drying and made a kind of sheet. Vermiculite sheet is a porous material with hundreds of millions of pores with a diameter of one micron (one-seventieth of the diameter of a hair) per cubic centimeter. The excellent porosity of the plate in the high temperature environment of the thermal conductivity stability has also become a fire, thermal insulation, heat insulation, sound insulation products of choice. Vermiculite board has the characteristics of fireproof, heat preservation, heat insulation, sound insulation, etc., and at the same time, it has a certain strength, cutting, slotting, punching can be.
