摘要:
为进一步提升我国钢制管道防腐工艺水平,分析了钢质管道防腐生产表面预处理工艺中碱洗、酸洗、钝化三个处理工艺的作用及原理。碱洗可以除去管道表面的油脂和污物;酸洗可以使抛丸除锈后的管道表面形成磷化膜,提高钢制管道表面清洁程度和涂层的粘接性能;钝化可以提高钢制管道表面磷化膜的稳定性。调查发现,该预处理方式已经广泛应用于国外钢制管道的防腐生产中,但目前在国内的钢制管道防腐生产中很少用到,也缺少相应的规范和检测手段,认为我国应加强这方面的研究和实践。
Abstract:
In order to further improve the level of pipeline anticorrosion technology in China, the effects and principles of three treatment processes of alkali washing, pickling and passivation in the surface pretreatment process of pipeline anticorrosion production were analyzed. Alkaline washing can remove grease and dirt on the surface of the pipeline; pickling can form a phosphate film on the surface of the pipe after blasting and rusting, improve the surface cleaning degree of the steel pipe and the bonding performance of the coating; passivation can improve the stability of the surface phosphating film of steel pipe. The investigation found that this pretreatment method has been widely used in the anticorrosion production of foreign pipelines, but it is rarely used in China, and there is no corresponding norm and detection means. Therefore, China should strengthen research and practice in this aspect.
