Description

一种钢结构聚脲弹性体喷涂式防腐施工方法
技术领域
本发明涉及一种钢结构聚脲弹性体喷涂式防腐施工方法。
背景技术
大气环境下的钢结构受阳光、风沙、雨雪、霜露及一年四季的温度和湿度变化作用，其中大气中的氧和水分是造成户外钢铁结构腐蚀的重要因素，工业气体含有SO2、CO2、NO2、CI2、H2S及NH3等，这些成份虽然含量很小，但对钢铁的腐蚀危害都是不可忽视的，其中SO2影响最大，CI2可使金属表面钝化膜遭到破坏，这些气体溶于水中呈酸性，形成酸雨，腐蚀金属设施。
钢结构常用加重腐蚀涂料构成长效防腐结构，或者用配套重防腐涂料涂装防护。金属锌、铝具有很大的耐大气腐蚀的特性。在钢铁构件上喷锌或喷铝，锌、铝是负电位和钢铁形成牺牲阳极保护作用从而使钢铁基本得到了保护。此类方法大多单独使用，锌、铝的过度使用将造成浪费，防腐涂料种类繁多，对环境有毒有害。
