摘要
以高炉渣为主要原料制备吸声泡沫玻璃,考察玻璃厚度、空腔、边缝以及开口气孔率对吸声性能的影响。结果表明,在低频区域,厚度、空腔深度和开口气孔率的增加都能提高吸声系数。但厚度超过150mm后对吸声系数提高意义不大。吸声系数只在500～3 000Hz频率范围内随边缝的增加而提高,其他频率范围内,吸声系数变化不大。
Sound-absorbing foam glass was prepared from blast furnace slag. The effects of glass thickness, depth of cavity, side seam and opening porosity on absorption properties were investigated. The results show that increasing of thickness, depth of cavity, and opening porosity can improve sound absorption coefficient at low frequency, but the thickness exceeding 150 mm has little effect on absorption coefficient. Sound absorption coefficient rises with increasing of side seam only within the frequency range of 500 ～3 000 Hz.
