我公司用特种工艺生产了专门供空调风管使用的空调板容重64kg/m3以上,厚度为25—30mm的玻璃棉板为基材。用防火粘合剂在二面分别粘敷玻璃丝布和铝箔布制成复合玻璃棉板。再经过切割、开榫、粘结等工序做成各种规格的方形管道(玻璃丝布面在内,铝箔布面在外)。此管道广泛用于矿山、建筑的通风和中央空调工程。是替代镀锌板风管和玻璃风管的新型产品。
用途: 此种管道不仅具有良好的吸音、绝热、阻燃、防潮性能而且经济适用,节省工程造价15%,施工方便。

Centrifugal glass wool felt
The centrifugal glass wool felt is a kind of scrolling materials made for the large area laying. Besides heat insulation and thermal insulation, it has other advantages such as excellent damping and sound absorption, especially for intermediate and low frequency and all kinds of noise concussion, noise reduction and working environment improvement.
The materials can be cut at random according to the construction is mainly used on the following aspects:rooms of buildings,sound reduction system,mean of communication, refrigeration equipments, damping, and sound absorption and noise reduction of domestic electric appliance, which has a satisfatory effect.
The glass wool felt with aluminium foil on the surface has the effect of heat radiation hardening, a lining material mainly used in high-temperature workshops, control room, inner wall of computer lab,isolated room and flat top.
