What is the role of the vermiculite fireproof material?
The vermiculite fireproof slate is widely applied to construction, shipbuilding, metallurgy, electric power, aerospace and other fields by foreign countries. Vermiculite slate can be applied to furniture, firewall, ceiling, and can be used in the fire fighting access, coated steel, coated pipeline, real flame fireplace in the lining board, wall partition. It is characterized by non combustible, non melting, resistance to high temperature; permanent thermal insulation; sound insulation, non-toxic, smoke-free, green environmental protection; resistance to impact, good dimensional stability and durability of the excellent anti fungal infestation. It can be sawed, nailed, planed, drilled, it can be easily installed and constructed.
Apart from inflaming retarding, the materials covered with vermiculite has a lot of advantages including anti rust, waterproof, anticorrosive, wear-resisting, heat-resisting and the coating is armed with toughness, colorability, adhesiveness, fast-drying and luster.
It can be widely used in construction, decorative ceiling, wall, floor and fireproof door . Especially suitable for airport, railway station, passenger terminal, exhibition hall, hotels, shopping malls, hotels, and other public places and factory, fuel warehouses which have high requirements for fire proofing, etc. With its special thermal insulation, it can also be made to the various types of heat insulation board offered to machines (such as a variety of industrial furnace and assembly line equipment) and furniture, etc. Due to the low density of the product itself, a lot of shipyards in foreign countries use it as ceiling, wall and deck, so the development potential of the domestic shipbuilding market is huge.Expanded vermiculite is porous, lightweight, and dystectic, the most suitable for insulating materials at high temperature (below 1000℃) and fire insulation materials. In the experiment, 15cm- thick cement vermiculite burns for 4-5 hours under 1000℃, but the back temperature is only 40℃. 7 cm-thick vermiculite slate burns for 5mins through the fire flame welding net under 3000℃, the frontage melted, but you don’t feel hot with your hands holding the back side. According to aforementioned, vermiculite slate is superior than all insulating material, such as asbestos, and diatomite products.
