2. Description of vermiculite insulation board
Vermiculite insulation board is a new type of insulation and flame retardant material, which is made of expanded vermiculite and inorganic adhesive, and is formed by hot pressing or air pressure molding. The product has the characteristics of high temperature resistance, fire prevention, green environmental protection, thermal insulation, and sound insulation. It does not contain toxic and harmful substances such as asbestos, formaldehyde, benzene, etc. After being heated to 1200 ℃, it does not produce gases that are harmful to human health, and its combustion performance reaches Class A.
Due to the fact that vermiculite insulation board is mainly made of expanded vermiculite as the main raw material, it is an inorganic material that is non combustible, non melting, and resistant to high temperatures.
Its melting point ranges from 1370 ℃ to 1400 ℃, and its maximum operating temperature is 1200 ℃. Without carbon and sulfur elements, it will not produce CO2 and SO2, which will affect the environment and pose a threat to human health.
The product has high strength and toughness, good dimensional stability and weather resistance, excellent resistance to mildew and insect infestation.
The product is widely used in fields such as construction, metallurgy, power electricity, and shipbuilding.
3. Main characteristics of vermiculite insulation board
1) Green and environmentally friendly, free from formaldehyde and benzene substances, asbestos, carbon, and sulfur elements, and will not produce toxic or harmful substances after high temperatures.
2) High temperature resistance, with a maximum operating temperature of 1200 ℃.
3) Flame retardant, thermal insulation, sound insulation.
4) Good dimensional stability and weather resistance.
5) Easy to process and convenient to install.
4. Main purpose of vermiculite insulation board
The vermiculite insulation board is widely used in fields such as construction, metallurgy, power electricity, and shipbuilding. Its function is flame retardant, thermal insulation, and high temperature resistance.
