color-coated corrugated roofing sheet manufacturer introduces color steel plate various core material functions: 1. Color steel sheet foam board: It is made of expandable polystyrene (EPS) particles, which is like chemical fertilizer particles. It is pre-expanded by heating, and it becomes larger particles like white pearls, and then heated and pressed in the mold. A foamed sheet material having a fine closed cell structure. 2. Color steel sheet polyurethane: fire insulation and thermal insulation machine is an excellent material, the weight of polyurethane used for the composite board is generally 30 kg - 40 kg; 3. Color steel rock wool sheet: It is made of basalt stone as the main raw material. After high-temperature melting, it is made into the inorganic fiber by high-speed centrifugal equipment. At the same time, a certain proportion of binder is added to bake into a large plate, and the rock is cut according to the need of the basin. The sliver and rock wool are non-combustible and the fireproof function is good. 4. Color steel sheet glass wool: is a light, heat-resistant, flexible, otherwise thermal insulation material, widely used in chemical, pharmaceutical, factory, heavy industry machinery and equipment, construction, vehicles, aerospace, is an ideal heart-breaking, fireproof, sound absorbing materials. 5. Color steel plate flame retardant paper honeycomb panel: for the national B1 fireproof material, with good flame retardancy, good compressive strength, only carbonization does not burn, does not produce toxic substances, waste can be completely accepted and reused, etc. It is an ideal substitute for core materials such as polystyrene, polyurethane, and rock wool. The above is the introduction of various core materials for color steel plate suppliers. If you want to know more about color steel plates, please keep an eye on us.
