1.1 本说明书是依据上海国际油漆有限公司提供的10年寿命的油漆配套而制定的

1.2

(全部涂装工作包括钢材表面预处理和油漆检验，这些工作的实施必须依照船厂的惯例和国际标准以及油漆商的推荐)

1.3

(本说明书所使用的主要标准是ISO 8501-1; 1988(E), 即涂漆和相关产品之前的钢底材处理－表面清洁度的目视鉴定以及SSPC（美国保护涂层协会）的相关标准)

2、(表面处理)

2.1

(钢材流水线预处理)

1）The hull structure steel plates (6mm and above) are to be abrasive blasted to ISO 8501-1

Sa2.5, the bar sections are to be abrasive blasted to ISO 8501-1 Sa2, and primed with

18microns Taicang Lanyan Paint Factory’s inorganic zinc silicate shopprimer W53-02.

(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) 2）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)

3）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)

1）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)

2）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)

3）The surface of steel structure including all welding beads shall be painted as specified hereafter

PAGE: 3 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 Taicang Lanyan Paint

Fac tory’s shopprimer to prevent corrosion before leak test.

(所有钢质构件表面包括之后要进行密性试验的焊缝都要进行涂装，然而那些构成舱室

密性的焊缝在密性试验前要用太仓兰燕的车间底漆刷涂干膜厚度不能超过30μm)

2.3 Secondary surface preparation (二次表面处理)

1）Secondary surface preparation shall be carried out as below table and A, B, C, D, E in t

(二次表面处理方法见下表，其中A, B, C, D, E分别代表以下处理方式：)

A:

(分段阶段焊接及烧损部位喷砂至Sa2.5级，车间底漆完好部位扫砂至车间底漆残留面积不超过30%)

B:

(分段阶段焊接及烧损部位打磨至St3级)

C:

(分段总组合拢后焊接及烧损部位打磨至St3级)

D:

(分段阶段不处理，合拢后喷砂至Sa2.5级)

E:

(分段阶段不处理，合拢后打磨至St3级)

2）

(表面处理前，应清除油污及其它杂物，对钢板缺陷，焊接飞溅等应进行修补) 3）(在二次表面处理前，在分段上的密性焊缝应完成密性试验；对于没有完成密性试验的密性焊缝，在喷砂交验后，应刷涂车间底漆，然后贴压敏胶带，当涂装检验工作结束时，应立即拆除密性焊缝上的压敏胶)

4) 总组焊缝及烧损破坏处需打磨处理。对于这些部位的修补，首先将损坏处拉毛呈斜
