綠色發泡材料eFoam噪音阻隔成效探討

發泡塑膠是以熱塑性或熱固性樹脂為基體，其內部具有無數微小氣孔的塑膠。發泡塑膠可以說是以氣體為填料的複合塑膠。發泡材料具有隔熱保溫、防水防潮及隔音等特性，本研究旨在探討此材料的隔音特性，將此一特性應用於複合牆體上，以達到良好的隔音效果。本研究大致上分為兩個部分，第一部分的試驗是測試電子架橋PE泡棉單層、岩棉，以隔音箱進行大量隔音試驗。第二部分的試驗為雙層及三層複合組合隔音的成效，以隔音箱進行多組不同組合的隔音試驗，測試所有不同倍率不同厚度組合的電子架橋PE泡棉。由此兩部分的試驗所得知的結果，發泡材料在阻隔聲音能達到一定的效果。顯示電子架橋PE泡棉在建築領域的應用上能夠取代傳統材料，達到環境保護、節能、減排的功效。

Foam plastic is a thermoplastic or thermoset resin matrix, which has countless tiny pores inside the plastic. Foam plastic can be said for the gas filler is a composite plastic. Foamed material having insulation, soundproof and waterproof properties, this study was designed to investigate the noise properties of this material, this attribute is applied on a compound wall, in order to achieve good sound insulation This study would be divided into two parts. The first part of the experiment was to test the electronic bridge PE foam single, rockwool to soundproof extensive soundproofing test. Test results for the second part of the double and triple soundproof complex combination of multiple groups with soundproof insulation test different combinations to test all the different combinations of different thickness ratio of electronic bridge PE foam. Whereby the two parts of the test results that the foam sound barrier material to achieve a certain effect. Display can replace the electronic bridge PE foam applications in the field of traditional building materials, to achieve environmental protection, energy saving, emission reduction effect.
