钢构防腐漆的涂装方法及耐腐蚀机理

发布日期:2019-09-25 作者:福建钢构防腐漆 点击:

福建钢构防腐漆是在耐油防腐蚀涂料的基础上研制成功的一种新型钢结构防腐蚀涂料。该涂料分为底漆和面漆两种,除了外,其应用范围更广,并且可根据需要将涂料调成各种颜色.在加工、运输、存放等过程中,表面往往带有氧化皮、铁锈制模残留的型砂、焊渣、尘土以及油和其他污物。那么接下来了解一下其涂装方法及耐腐蚀机理:

1.对一般的防腐底漆而言,它的防锈作用除依靠物理屏蔽作用外,在很大程度上还依靠防锈颜料的作用。如果水渗透到涂层内部进行腐蚀,铬酸锌、磷酸锌、偏磷酸锌、红丹等防锈颜料就会起到缓蚀作用。以钢铁用环氧磷酸锌防锈底漆为例,环氧磷酸锌防锈漆中普遍采用了磷酸锌作为防腐颜料。
