工程项目钢制螺栓腐蚀成因分析及预防措施

The Causes and Preventive Measures of the Steel Bolt Corrosion in Engineering Project

对国外工程项目上螺栓和螺母出现腐蚀问题的原因进行了分析,从产品的设计、生产、包装、运输、仓储和施工等环节,对常用螺栓腐蚀防护工艺进行研究,并结合工程实例,提出了黏弹体防腐方案、塑性保护帽防腐方案、有机热塑性涂层(TM198涂料)防腐方案等3种工程实践中行之有效的螺栓腐蚀防护方案。

The causes of corrosion problems of bolts and nuts in foreign engineering projects are analyzed,the corrosion protection technology of bolts in common use is studied from the aspects of product design,production,packaging,transportation,storage and construction.Combined with engineering practice,the schemes of anticorrosion of viscous elastic body,plastic protective cap and organic thermoplastic coating(tm198 coating)are put forward which are effective in practice.
