(船体结构用钢板（6㎜以上厚度）都要进行抛丸处理达到Sa2.5，型钢材抛丸除锈达到Sa2，处理后立刻用太仓兰燕的无机硅酸锌车间底漆喷涂，干膜厚约为18μm) The steel plates less than 6mm and the pipes which are considered to be impractical for sand blasting shall be cleaned by pickling or power tool in accordance with the Builder’s practice. (6㎜以下钢板及不能进行打砂的管子按照船厂的惯例采用酸洗或动力工具处理) The painting manufacturer shall confirm the compatibility between the painting system and shopprimer. (油漆商应确认车间底漆与后序涂层配套的兼容性) 2.2 Application of Touch-up primer (跟踪补漆) In block fabrication stage, welded joints and parts where could be easily rusted by the weather exposure during assembly an could have damaged shopprimer shall be mechanically cleaned to Swedish Standard SIS St3, and immediately touched up less than 20 microns Taicang Lanyan Paint Factory’s shopprimer. (在分段拼装阶段，烧焊部分和接头在外界空气中容易锈蚀，还有那些车间底漆被破坏的部分都要机械打磨至St3，之后立刻用太仓兰燕的车间底漆进行修补至20μ左右) Erection joints shall be touch-up with Taicang Lanyan Paint Factory’s shopprimer at pre-erection stage or dry dock stage prior to the air tests. (上层建筑的大焊缝接头在吊装和干船坞的空气试验前要用太仓兰燕的车间底漆进行修补) The surface of steel structure including all welding beads shall be painted as specified hereafter before leak test. However, fillet welding joints and erection seams/butts joints forming tank boundary may be touch-up less than 30 microns of D.F.T. with
