The sandwich material of the color steel plate is divided into a foam color steel plate (chemical name is polystyrene color steel plate), a rock wool color steel plate, a polyurethane color steel plate, a paper honeycomb sandwich panel, and a glass wool color steel plate.
Foam color steel plate is an organic material, which has the characteristics of light insulation, light weight and easy installation. It has been widely used in recent years. One of the downsides is that the foamed color steel plate is extremely easy to burn and does not meet the national fire protection requirements.
Rock wool color steel plate is a new type of fireproof board with the strongest fire resistance performance in the color steel plate series. It is made of natural rock, blast furnace iron ore slag, etc., which are melted into filaments at high temperature and then solidified. The rock wool color steel plate meets the secondary fire protection requirements of the clean workshop, and is the most ideal structural decorative plate for indoor ceiling and movable house construction. It has a fire resistance of 600 ° C and a fire rating of Class A. It is polystyrene and there is no comparison of polyurethane. Its core material is rock wool that cannot be burned.
The polyurethane sandwich panel is composed of upper and lower color steel plates and intermediate foamed polyurethane. It is one of the most widely used building materials in the construction industry. It has good insulation, heat insulation and sound insulation effects. The polyurethane added with fireproof material does not support combustion.
Glass wool and phenolic foam cored steel plates are slightly more expensive than foam. The phenolic foam material is a polymer organic hard aluminum foil foam product which is formed by foaming a thermosetting phenolic resin. It has the characteristics of light weight, fire prevention, no fire, no smoke, no toxicity, no dripping, wide temperature range (-196~+200°C), no shrinkage and no embrittlement under low temperature environment.
