Vermiculite is made of sheet metal with expanded vermiculite and a certain dose of adhesives, after hot pressing or cold pressing. It has high strength and wayward. The plate also has the characteristics of thermal insulation, fireproofing, asbestos-free, high-temperature heating to 1200 degrees Celsius does not produce gases endanger human health, the combustion performance of Class A This product can be used in the core of fire doors, fireplace lined with wall materials. Vermiculite is a new type of building materials in China is still in the prototype stage, the major domestic export vermiculite raw materials, finished products in the domestic rarely use, but in recent years, the domestic market demand is gradually increasing. In the United States, Britain, France and other developed countries has long been widely used in the 1980s. Vermiculite characteristics: non-flammable, non-melting, high temperature, expanded vermiculite vermiculite as the main raw material, inorganic material carbon does not burn. The melting point of 1370 ~ 1400 ℃, the maximum temperature of 1,200 degrees Celsius, as well as long-lasting insulation. Chen Xing Industrial production quality vermiculite Xinjiang asbestos vermiculite is made of non-toxic, non-smoking, green, inorganic material carbon elements and elemental sulfur, and not born of these affect the atmosphere of CO2 and SO2 air nor will it cause harm to humans.
