摘要
大气区钢结构关键部位由于其结构复杂,表面处理困难,采用涂层防护无法起到良好的防腐效果,而氧化聚合型包覆防腐蚀技术针对钢结构的关键连接部位具有优异的防护效果。氧化聚合型包覆防腐蚀技术由3层紧密相连的保护层组成,依次为防蚀膏、防蚀带和外防护剂。该技术对钢结构表面处理要求低,防蚀膏与钢结构表面紧密结合起到缓蚀防锈作用;防蚀带粘贴在钢结构表面,永久保持非固化、柔软的状态,从而达到最佳的防腐性能;外防护剂与空气接触氧化聚合,形成坚韧的皮膜,具有优异的耐老化性能,由于该材料具有良好的柔软性,能够抚平、粘贴在任何形状表面,因此可以广泛适用于各种复杂形状的结构或构件,被称为"可粘贴的重防腐涂料"。氧化聚合型包覆防腐蚀技术施工工艺简单,节省施工时间,有效防护寿命长,已证明是解决大气区钢结构关键部位腐蚀难题的十分适用的防腐蚀技术。
Paints cannot play a good effect for allotype junction of steel structure at atmospheric zone, because of the complex structure. The oxidative polymerization coated anti-corrosion technology has excellent performance for allotype junction of steel structure. Oxidative polymerization coated anti-corrosion technology consists of three closely linked protec- tion layers , followed by anticorrosion grease, anticorrosion tape and outer protective agent. Anti-corrosion grease can change the rust into ferrous oxide film, the outer side of anti-corrosion tape has good UV-resistant property because of con- tacting with the air and forming oxidative polymerization film, the inner side of anti-corrosion tape pastes the steel structure surface and keeps the tape soft. So we call these kinds of materials anti-corrosion paint that can be stuck on. Oxidative polymerization coated anti-corrosion technology is simple construction process, saving construction time, with effective pro- tection and long life, has proven to be suitable anti-corrosion technology to solve the atmospheric corrosion problem of key part of steel structure.
