產品描述：
中高頻(pin)消聲(sheng)(sheng)(sheng)(sheng)性能(neng)優良，氣流阻力小(xiao)，因此適(shi)用(yong)范(fan)(fan)圍(wei)非(fei)常廣。它是(shi)在大(da)尺寸風管(guan)內設(she)置一定(ding)數(shu)量的(de)(de)(de)(de)吸(xi)聲(sheng)(sheng)(sheng)(sheng)片(pian)(pian)(pian)，構成多個扁形(xing)消聲(sheng)(sheng)(sheng)(sheng)通道并聯的(de)(de)(de)(de)消聲(sheng)(sheng)(sheng)(sheng)器(qi)。片(pian)(pian)(pian)式消聲(sheng)(sheng)(sheng)(sheng)器(qi)的(de)(de)(de)(de)消聲(sheng)(sheng)(sheng)(sheng)性能(neng)主要(yao)取決(jue)于其(qi)吸(xi)聲(sheng)(sheng)(sheng)(sheng)片(pian)(pian)(pian)吸(xi)聲(sheng)(sheng)(sheng)(sheng)系數(shu)、片(pian)(pian)(pian)厚、片(pian)(pian)(pian)距及(ji)長度(du)。吸(xi)聲(sheng)(sheng)(sheng)(sheng)片(pian)(pian)(pian)的(de)(de)(de)(de)用(yong)料及(ji)厚度(du)決(jue)定(ding)片(pian)(pian)(pian)式消聲(sheng)(sheng)(sheng)(sheng)器(qi)的(de)(de)(de)(de)消聲(sheng)(sheng)(sheng)(sheng)頻(pin)率特性，在中、低(di)頻(pin)范(fan)(fan)圍(wei)內厚度(du)有最大(da)的(de)(de)(de)(de)影響，片(pian)(pian)(pian)厚增(zeng)大(da)，吸(xi)聲(sheng)(sheng)(sheng)(sheng)系數(shu)亦隨之增(zeng)加(jia)，可提高低(di)頻(pin)消聲(sheng)(sheng)(sheng)(sheng)性能(neng)，但也會帶來阻力及(ji)體(ti)(ti)積增(zeng)大(da)的(de)(de)(de)(de)問題(ti)；工程(cheng)上超(chao)細玻璃棉常用(yong)體(ti)(ti)積密(mi)度(du)為(wei)20～30kg/m^3，增(zeng)加(jia)體(ti)(ti)積密(mi)度(du)主要(yao)在中、低(di)頻(pin)吸(xi)聲(sheng)(sheng)(sheng)(sheng)系數(shu)方面有增(zeng)大(da)的(de)(de)(de)(de)趨勢。一般情(qing)況下(xia)建議通過消聲(sheng)(sheng)(sheng)(sheng)器(qi)的(de)(de)(de)(de)氣流速(su)度(du)以(yi)＜8米(mi)/秒(miao)。
