 ◆ 产品优势

　　聚氨酯岩棉板硬质发泡是目前公认好的建筑围护防火保温板材。其导热系数低、耐荷性好、抗弯强度高、不吸水、不腐烂、不虫蛀鼠咬、阻燃性好、耐温范围大。利用聚氨酯( PU.PIR )的物理特性及独特配方，将聚氨酯发泡剂均匀喷覆在彩涂钢板上，使发泡剂在彩涂钢板之间发泡成型成为三层一次性成型的聚氨酯( PU.PIR )彩钢复合夹芯板。这种新的轻型建材是彩涂钢板与聚氨酯的结合，是轻型建材的发展方向。

 ◆ 产品特性

　　▲ 密封性能：聚氨酯岩棉板采用了流水线生产工艺，从而利用了聚氨酯产品优异的防水性克服了岩棉易吸水潮解的缺点，在物理性能上有效延长了产品的使用寿命。

　　▲ 美观性能：接口采用欧洲标准进行设计，外观圆润流畅，板面平整美观，接缝严密，强度可靠，有效防止冷热桥的产生。

　　▲ 刚度好：聚氨酯岩棉芯材与两层钢板粘接成一个整体，共同工作，再加上屋面板上表面起波压型，其整体刚度远胜于压型板夹岩棉(玻璃丝棉)的现场复合板材。夹芯板通过连接件与檩条固定后，大大提高了屋面的整体刚度，加强了屋面整体工作性能。选用岩棉夹芯板，可采用较大檩距，故可节省檩条用量1/3～2/3。

　　▲ 扣接方式合理：聚氨酯岩棉屋面板采用暗扣连接方式，避免了屋面板接缝漏水的隐患，节省了配件用量。

　　▲ 固定方法牢固合理：聚氨酯双侧封岩棉屋面板采用特制M6自攻螺丝与檩条固定，能有效抵抗台风等外力作用。自攻螺丝设置在屋面板两板接缝之间的波峰位置，并采用特殊的防水构造，避免产生防水薄弱点。

　　▲ 安装周期短：聚氨酯岩棉板，由于现场无须二次加工，不仅可保持周围环境的整洁，不影响其它工序的正常进行，而且可以大大缩短板材的安装周期，岩棉夹芯板的日平均安装面积达600～800m2。

　　▲ 防划伤保护：聚氨酯岩棉板在生产时，可在表面粘贴聚乙烯不干胶保护膜，以避免运输及安装过程钢板表面涂层受到划伤或磨损。

　　▲ 防火性能优异：聚氨酯双侧封岩棉夹芯板采用的原材料、生产工艺及配方，使它具有很好的防火性能。试验表明，它具有超过1000℃的耐火能力。聚氨酯双侧封岩棉夹芯板已通过了意大利权威检测机构GIOROANO S.P.A的测试

　　▲保温隔热性好：聚氨酯双侧封岩棉夹芯板的保温隔热性是以岩棉的导热系数λ=0.043 W / m2 K为依据，以相应比例的岩棉芯材的厚度计算求得的。

　　▲隔声吸音效果显著：聚氨酯板对噪声传递有显著的削减作用，特别适用于有航班通过的地方。另外，采用了岩棉屋面板后，雨水、冰雹对建筑物的屋面钢板冲击而引起室内声响，也明显减弱。通过测试，按照ISO 717/82和UNI 8270/7标准，选用密度为120kg/m3岩棉作芯材的夹芯板，隔声效果可达到RW=29~30 dB。

　　岩棉夹芯板同时具有极好的吸音效果，它能吸收较广频率范围内的声音。按照ISO 354/85标准，岩棉夹芯板吸音性能水准达到DELTA LA=15.7 dB(A)。

　　聚氨酯板充分发挥了岩棉芯材的独特性能，在防火、保温隔热、吸音隔声等方面有着显著的功效;同时又保留了聚氨酯可塑、密闭、高强、不吸水的优点。此材料的问世是建筑工程方面一次革命性的改变，使得聚氨酯、岩棉的优点得到了充分的融合，屏弃了传统板材存在的缺点。在某种意义上讲，聚氨酯岩棉板与普通岩棉夹芯板不能相提并论。
