    Fire retardant coating is a large application industry of expanded vermiculite, and when it comes to steel structure fire retardant coating, many people first think of steel.
    Steel is a kind of building material that will not burn. It has the characteristics of earthquake resistance, bending resistance and so on. In practical applications, steel structure fire retardant coatings are not only steel products.
    Steel can increase the load capacity of buildings and meet the needs of aesthetic modeling in architectural design.
    Avoid defects such as concrete and other building materials that can not be bent or stretched.
    Why is there expansive vermiculite in the fire retardant coating of steel structure, and what role can expansive vermiculite play in it?
    Expansive vermiculite has excellent thermal insulation and fire resistance due to its structural changes.
    It is a layered structure with crystal water between the layers. Its bulk density is 50-200kg/m3, and its thermal conductivity is small. It is a good thermal insulation material. The quality of expanded vermiculite can reach 1100 OC at maximum tem
    Expanded vermiculite is widely used in insulation material, fireproof material, seedling raising, flower planting, planting tree, friction material, sealing material, electrical insulation material, paint, plate, paint, rubber, refractory material, hard water softener, smelting, building, shipbuilding, chemistry and other industries.
    However, there are some unavoidable defects in the fire prevention of steel as a building material. Its mechanical properties, such as yield point, tensile and modulus of elasticity, will decrease sharply due to the increase of temperature. There is a place where the expanded vermiculite is used.
    Therefore, expansive vermiculite can be used with steel and applied to various industries.
    At present, zhongrun  mineral resources have already taken over the processing of steel structure fire retardant coatings. If you need it,  welcome to contact us anytime.
