玻璃棉板在墻體中的使用方法

發(fā)布時(shí)間：2021-12-30 15:10:31 人氣：

在建筑中單層墻體因受質(zhì)量定律的限制，必須是重墻才能獲得良好的隔聲性能。對于住宅分戶(hù)墻，如果將墻體分成兩層或多層，隔聲量會(huì )顯著(zhù)提高。這是因為，聲音撞擊到第于消耗一層墻板時(shí)，透射的部分將進(jìn)入兩層墻板之間空腔，在空腔中來(lái)回反射多次后，一部分透射到墻體對面，另一部分被損耗掉。

　

　同時(shí)兩層之間的腔體有類(lèi)似彈簧的作用，使墻板系統具有有利聲音的彈性，進(jìn)一步隔聲。如果在腔體中填入離玻璃棉等吸聲材料后，聲音傳播過(guò)程中在腔體中來(lái)回反射的聲音將被大大衰減，隔聲量大為提高?？梢?jiàn)，隔墻腔體中的玻璃棉等吸聲材料對隔聲量的影響非常重要。

在吸納代建筑中建筑墻體能否起到比較好的聲音噪音凈化功能，對于用戶(hù)來(lái)講十分重要。其間玻璃棉作為具有良好吸聲性能的材料對于墻體的噪音凈化功能有著(zhù)很好的優(yōu)化作用。
