高桥热电厂系地下工程,因此需要一种防火、防潮的低频吸声材料,来解决地下厂房内部的噪音问题。我们五个单位在上级领导的关怀下,组成了三结合试验小组,通过共同努力,反复实践,试制成功了共振腔式吸声煤渣砖(330型低频吸声砖)。利用工业废料煤渣为主要原料制成的共振腔式低频吸声煤渣砖,用于砌筑高桥热电厂汽机房侧墙,这是一道约400米~2的风道墙,经二年多的使用,证明效果良好。由于采用了这种吸声砖,再加上其他
The Gaoqiao Thermal Power Plant is an underground project. Therefore, a low-frequency sound-absorbing material that is fireproof and moisture-proof is needed to solve the noise problem inside the underground powerhouse. Under the care of the superior leaders, our five units formed a three-combination experimental team. Through joint efforts and repeated practice, the resonant cavity-type sound absorption coal slag brick (330 type low-frequency sound-absorbing brick) was successfully trial-produced. Resonant cavity type low-frequency sound-absorbing coal slag brick made from industrial waste cinder as main raw material is used to build the side walls of the steam turbine room of the Gaoqiao Thermal Power Plant. This is a duct wall of about 400 m~2, which has been used for more than two years. , proved to be effective. Thanks to this sound-absorbing brick, plus other
