我国广泛采用超细玻璃棉、矿碴棉等作为控制噪声的材料,其吸声性能虽很好,但品种不够多,施工不便,应用范围往往受到一定的限制。最近,我们在北京毛纺织厂研究消除噪声措施中,发现纺织车间的飞花、下脚废毛等废纤维可做吸声材料。 废纤维作吸声材料,主要是利用其本身作为筋络骨? China widely uses ultra-fine glass wool, cotton ballast and other materials as noise control, although the sound absorption performance is good, but not enough variety, construction inconvenience, the application range is often subject to certain restrictions. Recently, we studied the noise reduction measures in the Beijing Wool Textile Factory and found that waste fibers such as fly waste and waste fur in the textile workshop can be used as sound absorption materials. Waste fiber for sound-absorbing materials, mainly using its own as a tendon complex bone?
