The core material of Suzhou color steel plate is divided into foam color steel sheet (chemical name polystyrene color steel plate), rock wool color steel plate, polyurethane color steel plate, paper honeycomb sandwich panel and glass wool color steel
The foam color steel plate is an organic material, it has the characteristics of heat insulation and light weight equipment. It has been widely used in recent years. One of the disadvantages is that the foam color steel plate is very simple and can not meet the requirements of fire protection.
Rock wool coloured steel plate is a new type of fire-proof plate with strong fire-resistant function in coloured steel plate series. It is made of natural rocks, blast furnace slag, etc. which are melted into wires at high temperature and then solidified. Rockwool coloured steel sheet meets the requirements of secondary fire protection of clean workshop, and is an ideal decorative plate for indoor ceiling and movable room. It has the function of refractory at 600 C, and the refractory grade reaches A. Polystyrene and polyurethane are not comparable. Its core material is rock wool which can not be burned.
_polyurethane sandwich board is composed of upper and lower color steel plate and foamed polyurethane. It is one of the widely used building materials in the construction work at that time. It has excellent thermal, thermal and sound insulation effects, and participates in polyurethane fire-proof materials without flame-retardant.
Compared with foam, the price of rock wool color steel plate is slightly more expensive than that of glass wool and phenolic foam sandwich steel. Phenolic foam is a polymer rigid rigid aluminum foil foam product, which is made from thermosetting phenolic resin. It has the characteristics of light weight, fire protection, non-burning in open fire, smokeless, non-toxic, no dripping, wide temperature planning (-196 ~200 C), no shortening and no brittleness in low temperature environment.
1. The sandwich color steel plate equipment is fast, the composite plate has light weight, splicing equipment and features that can be cut at will, and the selection of its equipment is concise, which can greatly benefit the Trek and save the construction period.
2. The sandwich color steel plate is light in weight and less than 14 kg in weight, which can fully reduce the structural load and reduce the structural cost.
_3. Durable, many discussions have been made and widely used abroad for more than 40 years. It has been proved that the shelf life of sandwich color steel plate treated with special coating is 10-15 years, and the shelf life of sandwich color steel plate can reach more than 35 years after spraying anticorrosive coatings every 10 years.
_4. It has the function of fire prevention. The surface material and thermal insulation material of the multicolored composite sandwich panel are non-combustible materials, which can fully meet the requirements of fire protection code.
5. Beautiful appearance, clear lines of profiled steel sheets can be up to dozens of colors, and the collaborative needs of any style of architecture, to achieve satisfactory results.
6. Heat preservation and insulation. The commonly used heat preservation materials of the composite board are: polyvinyl alcohol, rock wool, glass fiber wool, polyurethane and so on. These materials have low thermal conductivity. Then it is widely used in modern architectural decoration.
