机房、电梯井道隔音毡 GB22337-2008标准 A级玻璃纤维卷

电梯井道专用玻璃纤维针刺毡

一、20mm针刺毯隔声板系统构成:(简称:针刺毡隔声板) 针刺毯隔声板系统是由针刺毡隔声板加保温钉锚固件,搭接处用铝箔胶粘带密封并附加     镀锌钢丝网片加固,形成整体化一的保温隔声被衣,构成针刺毯隔声板系统。

 

二、20mm针刺毯隔声板生产工艺: 针刺毯隔声板是由针刺毡纤维经过短切、梳理、蓬化开松、梳理成网状、铺叠成毡、铺粘铝箔布、针刺制毡,针      刺机对针刺毯隔声板进行针刺,针刺时形成若干垂直针刺毡纤维,使针刺毡纤维互相联结,成为具有一定强度的针刺毡纤维。                                       三、20mm针刺毯隔声板的特点  针刺毯隔声板单丝无序交错穿插,呈无定向三维微孔结构,空隙小,空隙率高,具有良好的吸音、减震、耐腐蚀、         绝缘、耐高温、阻燃的性能。

 四、20mm厚针刺毯隔声板主要特性 1、导热系数低:根据物理原理,气体的热传导率小的断热材质内部均有很多空气穴。而针刺毯隔声板具有无数         细小气体,且纤维呈现不规则排列,为隔热材料,热传导系数0.20.030 W/(m.K)之间。
