Ref integrated thermal insulation and structure board for enclosure wall

The sandwich board consists of five layers. The front and back sides of the board are calcium silicate board, the middle is polystyrene particles, and the middle of calcium silicate board and polystyrene particle layer is polystyrene particle concrete. The thickness of the plate is 200mm, 250mm and 300mm (the thickness of polystyrene particle layer in the middle is 90mm, 10mm and 13mm in turn). With this thickness, we can see that the sandwich panel is thicker, more heat preservation and better sound insulation effect than the traditional light partition panel.

The specification of sandwich panel is 1.22 * 0.61m long and wide, which can be cut arbitrarily. The price is calculated in cubic meters instead of square meters. The price can be converted from 1200 yuan to 1100 yuan according to the thickness in the market.

Where can sandwich panels be used? What are the advantages?

Sandwich panels can be used as the exterior walls of some buildings, such as residential buildings, hotels, office buildings and other commercial buildings, schools, hospitals and other public buildings, industrial buildings and so on. The specific points are: the external wall of the hotel, the external wall of KTV, the internal and external wall of residential buildings, household partition wall, the thermal insulation wall of thermal insulation room, the external wall of rural reconstruction, etc.

The advantages of sandwich panel are: ① thermal insulation. It can be used in places with low temperature, which well ensures that the indoor temperature is not affected by the outside temperature. ② Sound insulation is good. It protects people's privacy. ③ Fire prevention. Under the high temperature of 1000 ℃, the fire resistance time shall not be less than 4 hours, and no toxic gas will be emitted, otherwise the performance will reach grade A1. ④ Safe, environment-friendly and pollution-free. ⑤ The installation is convenient, the labor intensity is reduced, the construction time is shortened, and the total project cost is saved.
