Decorative fireproof board is a kind of decorative material mainly made of fireproof board. In the production process, it is made of multi-layer kraft paper and decorative colored paper by high temperature pressing with impregnated resin glue. But the quality of raw materials used directly affects the quality of fireproof steel plate, including its environmental performance. Generally speaking, high-quality fireproof board will use high-grade kraft paper and imported decorative color paper as raw materials. In addition, the use of phenolic resin impregnated fire board, board quality, bonding ability, not easy to crack, the important thing is also has good environmental performance.
However, in order to save the production cost, some manufacturers often choose to use urea formaldehyde resin adhesive to produce fire insulation panels. The fire-retardant board impregnated with urea formaldehyde resin adhesive can not be compared with phenolic resin fire-retardant board in terms of environmental performance and board quality.
1. Heat insulation. The thermal insulation performance of fireproof board is 3 times that of clay, 6 times that of glass and 10 times that of ordinary concrete.
2. Light weight, high strength. Ordinary concrete 1 / 4, clay brick 1 / 3, lighter than water, equivalent to wood. The cube compressive strength is more than 4MPa. Especially in steel structure engineering, using ALC board as enclosure structure can give full play to its advantages of light weight, high strength, good ductility and strong seismic capacity.
3. Adapt to load. It can bear certain wind load, snow load and dynamic load.
4. Convenient processing. It can be sawed, drilled, grinded and nailed, which can reflect the design intention more easily.
5. Sound absorption and sound insulation. With different thickness, the noise can be reduced by 30-50 dB. The interior material of light panel series (EPS polystyrene particles) has good sound insulation performance and sound absorption function.
