泡沫玻璃

泡沫玻璃是一種以玻璃為主要原料,加入適量發泡劑,通過高溫遂道窯爐加熱焙燒和退火冷卻加工處理后制得,具有均勻的獨立密閉氣隙結構的新型無機絕熱材料。由于它完全保留了無機玻璃化學穩定性,具有容重低、導熱系數小、不透濕、不吸水、不燃燒、不霉變、不受鼠嚙、機械強度高卻又易加工,能耐除氟化氫以外所有的化學侵蝕。

泡沫玻璃不但本身無毒,化學性能穩定,以及能在超低溫到高溫的廣泛溫度范圍內不會變質的良好隔熱性能,而且本身又起到防潮、防火、防腐的作用。它在低溫深冷、地下、露天、易燃、易潮以及化學侵蝕等苛刻環境下使用時,不但安全可靠,而且經久耐用,被譽為“不需更換的永久隔熱材料”。所以被廣泛于石油、化工、建筑、冷庫、地下工程、造船、國防軍工等永久性工程的隔熱保冷。

目前國內泡沫玻璃由于受廢玻璃原有特性的局限,及加工工藝及設備等多種因素的限制,生產的產品質量較差,在導熱系數和抗壓強度等技術性能上與國外同類產品存在明顯的差距。

Foamed glass is a high-grade insulating material obtained by using glass powder as the base mixed with appropriate amount of foaming agert before baked and foamed in the turnel kilns and afterwards cooled and annealed. It is featured in independent air-clearance structure. Since it has completely retained the non-orgaric glass's chemical stabilities, it is featured in low volume capacity, small heat conductivity, none moisture permeation, none water alosorption, none fiame, no mold, resistance to roderts and high mechanical strength, capable of resisting all chemical corrosion except for fluorine hyclride.

The foamed glass is not only toxic free, but has stable chemical performance. Besides, it remains the same property in a wide temperature range and it resists the moisture, fire and corrosion. When used under deep-cold, underground, open air or stringent environment with flames, moisture or chemical corrosion, it is safe and reliable and durable, thus given the name of a permanent insulating material that never needs replacement. Therefore, it is widely used in the insulating for permanert engineerinng such as petroleum, chemical industry, construction, refrigerating warehouses, underground engineering, vessel building and civil defense.

Currertly, the domesfically producted foamed glass, due to the limitation of the original properties of the waste glass, as well as the processing equipments and other elemerts, has poor quality. There is an obvious gap in terms of heat conducting coefficient and pressure resistance as compared with the counterparts made inforeign counfries.
