产品说明:
泡沫玻璃是一种以玻璃为主要原料,添加适量发泡剂,通过窑炉高温发泡并经退火冷却后制得,具有均匀的独立密闭气泡结构的新型无机绝热材料。由于它完全保留了无机玻璃的化学稳定性,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”。所以被广泛应用于石油、化工、冷库、地下工程、造船、国防军工等永久性工程的隔热保冷。
Cellular glass is a new inorganic thermal insulating material with a structure of separate closed cells. The composition is glass, added with foaming agent. It’s foamed by high temperature in foaming furnace, and then cooled down in cooling oven. It well reserves the chemical stability of inorganic glass. As a result, it has the following features: low density, low thermal conductivity, vapor impermeability, no water absorption, incombustibility, protection from mould and rat eating, high mechanical strength but easy to process and able to bear all kinds of chemical erosions except the hydrofluoric acid.
Cellular glass, nontoxic in itself, has stable chemical properties and good thermal insulating performance protecting from deteriorating at a wide temperature range from cryogenic temperature to high temperature. At the same time, it can protect from humidity, fire and erosion. It is praised as "permanent thermal insulating material with no need of renewal", because it is not only safe but also durable in rigor conditions of low and cryogenic temperature, underground, open air, flammability, moisture sensitivity and even chemical erosion. Consequently, it is widely applied in permanent projects as heat and cold insulating material, such as in the industries of petroleum, chemical engineering, refrigerated warehouse, underground project, shipbuilding, national defense and war industry.
