详细，聚氨酯岩棉板性能全解！

（1） 重量轻：与具有相同保温隔热性能的粘土砖相比，其重量仅为1/19左右，大大降低了承重结构的外荷载，便于施工设备和运输。
（2） 耐火性：聚氨酯岩棉彩钢板面板为薄钢板，属于不灭火体，芯层为岩棉或矿棉，也属于不灭火体。岩棉是一种不含石棉和氟利昂的材料，具有良好的耐火性能。一般来说，50mm、75mm和100mm板的耐火时间分别可达1H、1.5h和4h。

(1) Light weight: compared with clay brick with the same heat insulation and heat preservation performance, its weight is only about 1 / 19, which greatly reduces the external load of load-bearing structure, and is convenient for construction equipment and transportation.

(2) Fire resistance: the panel of polyurethane rock wool board is thin steel plate, which belongs to non extinguished body, and the core layer is rock wool or mineral wool, which also belongs to non extinguished body. They are compounded by advanced technology and equipment, and rock wool is a kind of material without asbestos and freon, which has good fire resistance performance. Generally, the fire resistance time of 50 mm, 75 mm and 100 mm plates can reach 1H, 1.5 h and 4 h respectively.
Due to the demand of polyurethane rock wool board consumption process, the fiber produced by basalt melt centrifugation consumed by centrifugal method is bonded into the board, and the core layer must be pasted with the panel through glue, so the fire resistance time of rock wool sandwich board is slightly lower than the above time.
(3) Construction is convenient and fast: rock wool sandwich board construction is dry operation, the main work is to do a good job in connection and fixing all kinds of bolts and spare parts, the site operation is reduced to less, which improves the safety of construction, that is, there is no need for senior installation workers and secondary decoration, and greatly shortens the construction period.
(4) Thermal insulation: the thermal insulation of polyurethane rock wool board is based on the thermal conductivity of rock wool λ＝ Based on 0.043w/m2k, the core rock wool has good thermal insulation performance, which is more than 5 times higher than that of concrete slab; This makes the use of polyurethane rock wool board after the completion of the project, greatly saving air conditioning costs in hot areas, greatly saving heating costs in cold areas.
(5) Durability and decoration: the color of coated steel plate is increased, so that users can choose their favorite color, and do not need other decoration; Polyurethane rock wool board inside and outside are coated steel, life can reach more than 20 years.
(6) Seismic performance: engineering theory proves that under the action of earthquake force, sandwich panels are often in normal working state due to their good seismic performance.
(7) Sound absorption performance: the sound insulation effect of sandwich board with density of 100kg / m3 rock wool as core material can reach RW = 29 ~ 30dB.
