泡沫玻璃

泡沫玻璃是一种以玻璃为主要原料,加入适量发泡剂,通过高温遂道窑炉加热焙烧和退火冷却加工处理后制得,具有均匀的独立密闭气隙结构的新型无机绝热材料。由于它完全保留了无机玻璃化学稳定性,具有容重低、导热系数小、不透湿、不吸水、不燃烧、不霉变、不受鼠啮、机械强度高却又易加工,能耐除氟化氢以外所有的化学侵蚀。

泡沫玻璃不但本身无毒,化学性能稳定,以及能在超低温到高温的广泛温度范围内不会变质的良好隔热性能,而且本身又起到防潮、防火、防腐的作用。它在低温深冷、地下、露天、易燃、易潮以及化学侵蚀等苛刻环境下使用时,不但安全可靠,而且经久耐用,被誉为“不需更换的永久隔热材料”。所以被广泛于石油、化工、建筑、冷库、地下工程、造船、国防军工等永久性工程的隔热保冷。

目前国内泡沫玻璃由于受废玻璃原有特性的局限,及加工工艺及设备等多种因素的限制,生产的产品质量较差,在导热系数和抗压强度等技术性能上与国外同类产品存在明显的差距。

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.
