摘要
聚四氟乙烯(PTFE)的一些固有缺陷,限制了其作为防腐蚀涂层在化工领域中的应用。为了改善PTFE的性能,人们做了大量的研究工作。综述了国内外近几年来PTFE衬里的方法、衬里性能和衬里设备在化工防腐中的应用。介绍了PTFE防腐蚀涂层涂装工艺中的金属表面预处理、涂层配方设计及涂装方法等方面的研究进展,并指出了未来PTFE耐高温防腐蚀涂层的研究方向。
The inherence vices of PTFE limit it' s application as anti-corrosion coating in the engineering field. In order to improve the performance of PTFE, a lot of works have been conducted. The method and performance of PTFE lining, and the applications of PTFE lined equipment in the chemical anti-corrosion field both at home and abroad in recent years are summarizes. The developing progress of pretreatment of the metal surface,the compounding design for coating and the coating technique of PTFE anti-corrosion coating are introduced. The future developing direction of PTFE coating at elevated temperature is suggested.
