Furthermore , this paper forecasts future trend of the high - temperature corrosion - resistant materials applied in glass industry 另外,还对未来玻璃工业用高温耐性材料的发展趋势作出了展望。
This paper offers a comprehensive review of the current status of application of the high - temperature corrosion - resistant materials used widely by glass industry , as well as a description of the mechanism of metal and alloy corrosion in molten glass 摘要叙述了国内外玻璃工业常用高温耐蚀材料的应用现状,并就其中的金属及合金材料在熔融玻璃中的腐蚀机理作了介绍。
Ptfe is one of the most corrosion - resistant materials in the world . however it has defects such as the hot expansion and cold contraction rate is10 times larger than that of steel and the original cold fluidity ( creeping ) etc . therefore , as temperature increases , ptfe extends so excessively that it would collapse and then block the flow of media ; as temperature decreases , ptfe contracts so excessively that it would be ripped and then cause leakage Ptfe是当今最耐腐蚀的材料之一,可它被制造成衬里的时候,会存在热胀冷缩比钢铁十多倍及固有的冷流性等缺陷,致使ptfe衬里管道、设备,在使用过程中,温度高时, ptfe衬里层会伸长过多而内瘪,阻塞了介质流通;温度低时, ptfe层会收缩过大被拉裂而泄漏。
