Identification by spraying on both sides of tank, Request center spraying三、 罐体喷涂油漆要求tank spray paint requirements1、喷涂前进行表面处理，无凹坑、无夹层，边沿无毛刺，焊接接头、咬边、凸出处要打磨光滑，钢材表面无锈蚀、酸、碱、油脂等污物。For surface treatment before spraying, pits, interlining, edge, no burr, welded joint, bite edge, to smooth out, steel rust, acid, alkali, grease and dirt2、结构件表面喷砂除锈等级应达到Sa2.5级，其它部件表面除锈等级必须达到Sa2级。Structure surface sandblasting derusting grade should reach Sa2.5 level, the other part surface descaling grade must achieve Sa2 level3、油漆干透后漆膜应牢固地粘附在涂面上，不得有发粘、脆裂、脱皮、皱皮、气泡、斑痕及粘附颗粒杂质等缺陷，外观漆膜应均匀、细致、光亮平整、颜色一致，不得有流痕和明显刷痕。After paint dry film adhesion on the coating should be firmly, can not have sticky, embrittlement, peeling, wrinkled skin, bubble, flecked and adhesive particle impurity defects, such as exterior coating should be uniform, delicate, bright, smooth, consistent color can not have flow mark and clear brush marks4、喷涂油漆的标准为底漆两遍、中间漆一遍、面漆两遍，适合防腐要求在20年左右的。Standard for primer spraying paint twice, intermediate paint again, surface paint twice, is suitable for anticorrosion requirements in 20 years or so底漆：环氧富锌底漆，涂布率是2-3平方/公斤，两遍；中涂漆：环氧云铁防锈漆，涂布率是2-3平方/公斤，一遍。 面漆：氯化橡胶面漆，涂布率是4-5平方/公斤，两遍。Primer, epoxy zinc rich primer, coating rate is 2-3 square/kg, twice. epoxy micaceous iron oxide antirust paint, coating rate is 2-3 square/kg, it again. Finish: chlorinated rubber paint, coating rate is 4-5 square/kg, twice配料时应严格按配合比加料或加稀释剂，并使稠度适宜，边配边用。喷涂施工应分遍成活，必须在上一遍基本干燥固化后，再喷涂后一遍。Proportion of ingredients should be in strict accordance with the charging or add diluent, and the consistency is appropriate, preparation and use. Spraying construction should be accomplish step by step, must be in the basic dry again after spraying, after spraying again5、喷涂过程中，操作者应采用测厚针检测涂层厚度，直至达到设计规定的厚度时，方可停止喷涂。油漆干膜厚度保证在180um210um之间。Spraying process, the operator should use coating thickness thickness needle detection, until reach the thickness o
