For the current construction industry, the new building materials have obvious advantages, and the development prospects are also very optimistic. The same is true for Chongqing sandwich panels. The core materials are also divided into six types. They are Polystyrene sandwich panels are EPS sandwich panels. This is also the most widely used variety on the market. There are also extruded polystyrene sandwich panels, XPS sandwich panels, and rigid polyurethane sandwich panels, PU sandwich panels. Core board, three-polyester sandwich board is PIR sandwich board, phenolic sandwich board is PF sandwich board, and rock wool sandwich board is RW sandwich board.
The more its classification, the more extensive its use, in fact, the characteristics of sandwich panels also have very big advantages, first of all, its light weight, less than 24kg per square meter, can fully reduce the structure The cost, followed by the quick installation of the sandwich panel, light weight, insertion, installation and free cutting characteristics, determine its ease of installation, which can improve efficiency and save construction period. Another point is also very important. Its fire resistance and fire resistance , The ability is also very strong. The surface material and insulation material of the color steel composite core board are non-combustible or non-combustible materials, which can meet the requirements of fire protection regulations. The color steel plate treated with special coating has a new age of 10-15 years and a plate life of more than 35 years. After spraying anti-corrosion coating materials every ten years, the combination of all the advantages of sandwich panels and its characteristics will definitely have a very broad market.
Sandwich panels can be used in large industrial plants, warehouses, stadiums, supermarkets, hospitals, cold storage, mobile homes, building additions, clean workshops and places requiring heat insulation and fire prevention. Sandwich panels have a beautiful appearance, bright color and overall effect Well, it integrates load-bearing, heat preservation, fire protection, and waterproofing, and the sandwich panel needs to be decorated twice.
