重慶吸音板廠家淺談最簡單的隔音方法
編輯 : 重慶纖維噴涂廠家    2017-09-06 11:08:50


重慶吸音板廠家淺談最簡單的隔音方法。專業的隔音和吸音是一般的工程不需要的,也沒有這么大的成本去做這方面的聲學處理,更重要的是有一部分的場所我們只需要簡單的隔音和吸音,那么我們如何去做這種簡單的隔音和吸音的處理呢,現在我們廣州聲源建筑聲學材料公司來教您:


背景:

建裝修業和高層建筑和發展促進對輕墻的使用。許多高層建筑中往往有很多公司、單位,他們各占一層或幾層,這就決定了空間布局不可能按固定的模式設計,而采 用輕墻的靈活性正好客觀需要的多樣性。同時,采用輕墻還可減輕建筑的自重。但輕墻的隔聲性能差一直是推廣輕墻的一大障礙。

一般輕墻的平均隔聲量約為 30dB,難以用做分戶墻。而過去磚混結構的住宅分戶墻大多為240mm厚的磚墻,其平均隔聲量約為53dB,住戶一般是滿意的。為了提高輕墻的隔聲性能,可采取下面一些措施:  

措施:


1.做成夾層結構。即用多孔彈性植物吸音材料噴注密實。 如兩側均為雙層12mm厚的石膏板、鋼龍骨、中空75mm并內填超細玻 璃棉的輕墻構造,其平均隔聲量可達到49dB,而其單位面積質量只有240mm厚磚墻的十分之一。 

2.將空氣間層的厚度增加到處5mm以上時,在大多數的頻帶內可以增加隔聲量8—10dB。如兩側均為75mm厚加氣混凝土板、空中75mm的輕墻構造,其平均聲量可達50dB。用新舞臺吸聲材料填充空氣間層,可使隔聲量提高2—8dB。 


3.為了避免輕墻的吻合效應,可使各層材料的質量不等,以錯開吻合谷。 

4.輕墻的板縫密實程度對隔聲有較大的影響。雙層板應用錯縫搭接,單板應抹灰或勾縫。如每面單板,勾縫與否可相差12—17dB。輕墻兩側設置凹進去的電氣開關盒、插座盒等時,兩側的設置位置應相互錯開,周圍的縫隙應填塞好。 


如此的設計只需要我們在平常的建筑中就能夠實現,這樣既省了復雜而又昂貴的聲學材料又能達到我們想要的聲學效果。
