| 玻璃棉属于玻璃纤维中的一个类别，是一种人造无机纤维。采用石英砂、石灰石、白云石等天然矿石为主要原料，配合一些纯碱、硼砂等化工原料熔成玻璃。在融化状态下，借助外力吹制式甩成絮状细纤维，纤维和纤维之间为立体交叉，互相缠绕在一起，呈现出许多细小的间隙。这种间隙可看作孔隙。因此玻璃棉可视为多孔材料，具有良好的绝热、吸声性能。 Glass wool is a kind of artificial inorganic fiber, which belongs to one category of glass fibers. Natural ores such as quartz sand, limestone and dolomite are used as main raw materials to melt glass with some chemical raw materials such as soda ash and borax. In the melting state, flocculent fine fibers are formed by means of external blowing. There are three-dimensional intersections between fibers and fibers, which are intertwined with each other and show many small gaps. This gap can be considered as a pore. Therefore, glass wool can be regarded as porous material with good thermal insulation and sound absorption properties. |
