供應河北 A級外墻防火材料泡沫玻璃保溫板 隔音沫玻璃

·                                        泡沫玻璃是一種以玻璃質(zhì)為原料，經(jīng)過科學配制，再經(jīng)高溫焙燒而制成的具有大量的、相互貫通的、由表及里的吸聲材料。主要作用于減弱反射聲和混響聲，縮短和控制混響時間，現(xiàn)已廣泛應用大會堂、地鐵、高架橋、工廠噪聲車間、廣播錄音室等領域。吸聲泡沫玻璃作為現(xiàn)代建筑新型的吸聲材料，除了具有良好的吸聲性能外，還具有許多無機玻璃的物化性能所賦予的優(yōu)質(zhì)特性。

·                                            1、能耐高溫、遇火不燃燒；

·                                            2、無有害揮發(fā)物，對人體無毒性，無反射損害；

·                                            3、具有良好的化學穩(wěn)定性，不風化、不老化、不受蟲蛀、不會霉

·                                            爛變質(zhì)；

·                                            4、遇水不軟化、不吸濕、可用水沖洗，自然風干后仍保持原有的吸聲性能和形狀；因此，吸聲泡沫玻璃不僅是室內(nèi)裝飾吸聲材料，同時還能在室外環(huán)境條件下使用。
