英国Latty国际公司研制的Hephaistos密封材料系列可代替石棉,解决许多高温密封和绝缘的问题。这种产品是用氧化铝——二氧化硅纤维制造的,其性能远比石棉优越。除氢氟酸、磷酸或强碱外,Hephaistos产品不受其他物质的浸蚀,具有很好的化学稳定性。它的抗热冲击和抗振的性能极佳,导热系数低,隔音及电绝缘性能好。其中某些产品可承受1260℃的高温,适应面广。由于重量轻,使用方便,工业上应用的经济效益高,其密度只有普通石棉的一半,使用寿命却是石棉的2—3倍。 Hephaistos T在许多方面可代替石棉,包括热态煤气和热空气阀门的密封、管道的
The Hephaistos family of seals developed by Latty International UK can replace asbestos and solve many high temperature sealing and insulation problems. This product is made of alumina-silica fibers, and its performance is far superior to that of asbestos. In addition to hydrofluoric acid, phosphoric acid or alkali, Hephaistos products are not attacked by other substances and have good chemical stability. Its thermal shock and vibration resistance excellent performance, low thermal conductivity, sound insulation and electrical insulation performance. Some of these products can withstand 1260 ℃ high temperature, wide adaptation. Because of its light weight, easy to use, high economic benefits of industrial applications, its density is only half asbestos, the service life is asbestos 2-3 times. Hephaistos T replaces asbestos in many ways, including sealing of hot gas and hot air valves,
