- 陕京二线热煨弯管外防腐采用的单层熔结环氧粉末+丁基橡胶改性沥青防腐底漆+聚丙烯纤维增强型胶带的复合防腐结构,具有附着力强、耐化学介质性好、抗冲击性能高等特点。文章就这种防腐结构的防腐原理、防腐材料、施工技术和质量控制等进行简要介绍。
With the rapid development of long-distance oil and gas pipeline construction,more attention has been paid to coating quality of bends.The external coating of hot-bending bend applied in Second Shan-Jing Pipeline is composed of single FBE and butyl-based modified bitumen prime plus polypropylene fiber-re inforced tape.This kind of structure possesses good adhesion,excellent resistance to chemical attack and strong impact resistance.This paper presents a simple introduction to the coating structure in terms of principle,process and quality control.2001,1(1): 61-63,7 收稿日期：2010-5-18分类号：TE988.2作者简介：刘小利(1979-),男,陕西榆林人,工程师,2002年毕业于北京化工大学化工设备与机械专业,现从事管道防腐施工机械科研工作.参考文献：
