發泡材料是以熱塑性或熱固性樹脂為基材,以物理或化學的方式使內部充填無數微小氣孔的塑膠,可以說是以氣體為填料的複合塑膠。具有高強度、輕質、衝擊吸收、隔音和隔熱等效能,且可以透過改變配方及成型技術來改變其性能及用途。 本研究藉由試驗來探討環保電子架橋PE泡棉在建築材料領域應用的可行性評估。利用一般常見隔間材料如鋼浪板、矽酸鈣板及石膏板藉由組合發泡材料透過小型隔音箱參考ASTM規範進行快速、大量的試驗。以不同發泡倍率及厚度的發泡材料作為新式隔間牆的夾層墊材,並以多層式隔間牆結構配合不同的發泡材料對於隔音的效果,尋求改善輕隔間牆隔音的最佳材料。 由試驗所得結果,顯示環保電子架橋PE泡棉在建築領域的應用上能夠替代傳統材料,多層結構造可以達到更好的隔音的功效。材料質量對隔音性能之影響較大;而低厚度材料亦能夠改善隔音性能。透過試驗驗證原有硬質材料組合彈性材料不會造成音橋現象,確實證明低厚度材料仍對隔間牆的隔音性能有足夠的影響力。
Electronic bridge Foam (e-foam) material having a high strength, lightweight, shock absorption, sound insulation and heat insulation performance. E-foam can be change its properties and uses by the formulation and molding technology. In this study that assesses the feasibility of environmentally friendly PE e-foam applications in the field of construction materials by tests. Use common compartment material, such as steel, calcium silicate and gypsum panel. Reference ASTM specifications by a combination of e-foam do a lot and fast test through a small soundproof. E-foam materials with different expansion ratio and the thickness of the mat material as an interlayer of new partition walls, partition walls in multi-layered structure for different e-foam sound barrier effect, seek to improve the best material. e-From the obtained results, showed PE e-foam green can replace traditional materials in construction application. Multi-layer structure can be made to achieve a better sound effect. Quality of materials affects the noise performance large; the low thickness of the material can also improve sound insulation. But also low thickness of the material proof of sound insulation partition wall still has enough influence.
