鋼箱梁常用的防腐涂料底漆有富鋅底漆和環(huán)氧鐵紅底漆，富鋅底漆：富鋅底漆由大量的微細(xì)鋅粉與少量的成膜基料組成。鋅的電化學(xué)性比鋼鐵高，在受到腐蝕時(shí)，有”自我**”的作用，使鋼鐵被保護(hù)，而腐蝕產(chǎn)物氧化鋅又填充了孔隙使涂層更加致密。常用的富鋅底漆有以下三種： </p> <p> ①水玻璃無機(jī)富鋅底漆：它是以水玻璃為基料，加入鋅粉，混合后涂刷，固化后要用水沖洗。該底漆施工工藝復(fù)雜，工藝條件荀刻表面處理必須在Sn2，級(jí)以上另外對(duì)環(huán)境溫度、濕度都有要求形成的涂膜易開裂，脫皮，目前已很少采用。 </p> <p> ②醇溶性無機(jī)富鋅底漆：該底漆是以正硅酸乙酯為基料，以酒精為溶劑，經(jīng)部分水解聚合加入鋅粉混合均勻后涂覆成膜。主要用于鋼管、貯罐、橋梁集裝箱、船舶、海上平臺(tái)、海港設(shè)施以及惡劣腐蝕環(huán)境的底涂層，有陰極保護(hù)作用。 </p> <p> ③有機(jī)高鋅底漆：它是以環(huán)氧樹脂為成膜基料，加入鋅粉，固化形成涂層。環(huán)氧富鋅底漆不但防腐性能優(yōu)良，而且附若力強(qiáng)并與下道涂層環(huán)氧云鐵中層漆有良好的粘結(jié)性主要用于一般大氣中的鋼架結(jié)構(gòu)和石油化工設(shè)備的防腐。 T型梁指橫截面形式為T型的梁。上海梁計(jì)算繪圖一體化多少錢</p><p
