1.0 适用范围SCOPE

本专业方案适用于拜耳异氰酸酯和聚醚项目MDI联合装置罐区设备（V911、V912、V913）防腐油漆工程施工。This scheme is for the anti-corrosive painting engineering of the pipeline of Bayer Isocyanate & PET Project MDI Train-Tank Farm(V911,V912,V913).

2.0 工程概况GENERAL

该项目罐防腐为3号系统（system 3），分底漆，中间漆和面漆三层涂装，不锈钢（保温）罐为4号系统（system 4），分环氧清漆、面漆三层涂装，涂层总干膜厚度不低于200微米。This project, Bayer Isocyanate & PET Project MDI Train-Tank Farm has nineteen carbon steel tanks and six stainless steel tanks to be

antisepsis. The soleplates of carbon steel should be carried to the anti-corrosive place to do blast cleaning and painting (the components that can’t be derusted by the abrator should be derusted by blasting copper ore). Carry it to the construction scene after primary coat finished. Then, barrior paint and finish coat shall be covered when pressure has been tested and qualified(carbon steel tanks below 120℃). Below 120℃, the carbon steel tanks with derusting rating Sa2.5 is System 3. It should be covered with three coats including primary coat, barrior paint and finish coat. The epoxy zinc-rich primer should be thick 80 polyurethane finish coat60 thick. The dry coating should be 240 Stainless steel tanks below 120℃ is System 4. They should be covered with three coats. They are epoxy varnish, polyurethane finish coat.
