The prefab house is a super light building board made of color coated steel sheet, phenolic foam, self extinguishing polystyrene, polyurethane, glass wool and rock wool as core material, heated and compounded in a continuous molding machine with heat curing glue. Let's get to know its characteristics.
1. Specification diversification: there are enterprise type, H type, C type, corrugated type, etc., and the color is bright, without surface decoration.
2. Flexible and convenient installation: the composite plate can reduce the cost of basic engineering and structural engineering of the building, and can be disassembled and assembled many times, and the construction and installation are flexible and convenient.
3. Good fire resistance: the board core material is Class B1 flame-retardant material, with oxygen index ≥ 26, which will not melt when burning, and there is no black smoke, no high-temperature decomposition drop. It is a high-grade fire-proof building decoration composite board in China, and is the preferred decorative board for GMP workshop.
4. Wide range of use temperature: the use temperature of the plate core material is - 70 ℃ ~ + 120 ℃, which can reach + 200 ℃ in an instant. When it is used in low temperature or even ultra-low temperature environment, it has small shrinkage and no embrittlement. It is an ideal thermal insulation material for cold storage engineering
5. The thermal conductivity is low (λ < = 0.041w / MK), and the thermal insulation performance is good.
6. Nontoxic and odorless: the board core material is nontoxic and odorless when burning, and the overflowing gas has no harm to human body and environment, which conforms to the national environmental protection requirements. It is a new type of green building material.
7. Waterproof and moisture proof: the board core material belongs to the organic polymer foaming material, the structure belongs to the closed hole type, with good water absorption resistance and water vapor permeability resistance.
8. Light weight: 1 / 30 ~ 1 / 20 of the weight of concrete roof.
9. Long service life: the retention period of anticorrosive coating of color galvanized steel sheet is 15-30 years.
