There should be no grease, dirt, oxidation and rust contamination. There is only slightly dot or strip type splash remained on the steel surface.2.1.2焊接或成形后难以喷砂处理的部位，允许在焊接或成形前进行喷砂。If the area will be difficult to carry out sand blast after welding and shaping up, do sand blasting before welding.2.1.3工件表面处理后没涂底漆的零件不准与雨水、水汽接触，防止重新生锈。Prevent the parts after surface treatment from touching rain and vapour to avoid rust occur again2.1.4根据部件的多少来确定油漆的用量，并用适当的稀释剂调匀油漆，准备涂装。Prepare the paint according to the quantity of parts. Thin the paint with proper thinner before painting.2.2铝质零部件 Aluminium Parts 2.2.1固定过桥、活动过桥、检修平台、斜梯、泵站房和操控室壳体以及栏杆扶手等铝质件，其主要焊接件和冷作件在焊接前或下料成形后进行除油污等处理。 Degrease for the aluminium parts before welding or after shaping up, including fixed gangway, telescopic gangway, inspection platform, incline ladder and guardrail etc.2.2.2 进行除污处理后的零部件需要焊接的按有关要求进行，焊接后需要打磨焊缝的进行打磨抛光处理。The parts after degreasing may carry out welding according to relevant requirements. It must be ground and polished the weld seams.2.2.3 经过以上处理后的零部件按标准CB*/Z 92-81进行铝合金阳极氧化处理（铝合金矩形管型材在材料出厂前做阳极氧化处理）。The parts after the treatment steps mentioned above shall be carried out anode oxidation treatment. (Aluminium pipe profiles should be anode oxidized in the suppliers factory.) 2.2.4工件表面氧化处理后没涂底漆的零件必须做好保护措施。Protect the anode oxidized parts before shop primer coating.2.2.5根据部件的多少来确定油漆的用量，并用适当的稀释剂调匀油漆，准备涂装。Prepare the paint according to the quantity of parts. Thin the paint with proper thinner before painting.3. 涂装 Painting3.1 涂装厚度及油漆牌号根据船厂的要求；选用IP油漆。The coating thickness and paint brand are at the Shipyards option. Paint maker：IP.3.2 铝质零部件表面必须先涂一道蚀刻底漆。It is necessary to apply a layer of etch primer for the aluminium parts.4. 检验项目及方法 Inspection4.1 涂层的检验 Inspection of coating4.1.1 外观检验：在每度油漆的漆膜干后，应用目测方法检查油漆的表面质量，底漆、面漆涂层不允许有针孔、起泡、脱落、流挂、漏涂等缺陷，检验方法用目测。Visual inspection: Inspect and check the thickness of each layer of dry film by visual. Pinhole, air bubble, peeling and flowing etc. are not allowed. 4.1.2 同一种油漆涂装结束后，应用磁性涂层测厚仪，在油漆干膜表面上任意测三点（小型零附件除外）。三点平均值不得小于要求涂层厚度的90%。Measure 3 points at random on the dry film by tachometer after each type of paint coating is finished (except small parts). The average value of these 3 points has to equal to or more than 90% of the required thickness.5. 油漆牌号及颜色、涂层干膜厚度参见下表：Paint brand, colour, and dry film thickness see the table below:序号No.牌 号Brand名 称Description颜 色Colour每层干膜厚Dry film thicknessper layer （m）表面处理要求RemarksA. 钢质件热浸锌（扶手，栏杆）Galvanized steel structures (handrails, incline ladders etc.)铝质件扶手、栏杆：先涂一道蚀刻底漆1Intergard 269（EGA088/089）环氧底漆Epoxy Primer红色Red40轻扫砂或砂纸打磨Slightly sweep blast or sand paper abrade2Interseal 670 HSEGA 236/EGA247低表面处理环氧树脂漆Surface Tolerante Epoxy灰色Grey1603Interthane 990 PHB168/PHA046聚氨酯面漆Polyurethane Finish黄色Yellow50Total Dry Film Thickness 总干膜厚250Painting should be done by Airless Spray and Stripe Coating should be done with a brush prior to each Coat.喷涂方式采用高压无气喷涂，做每层油漆前边、角、焊缝、难以达到喷涂质量要求部位要进行预涂。B. 钢质件 steel structures.1Interseal 670 HSEGA 231/EGA247低表面处理环氧树脂漆Surface Tolerante Epoxy灰白色Offwhite150喷砂 Sa2.5Sand blast Sa2.5(ISO8501-1)2Interseal 670 HSEGA 236/EGA247低表面处理环氧树脂漆Surface Tolerante Epoxy灰色Grey1503Interthane 990 PHF259/PHA046聚氨酯面漆Polyurethane Finish橙色Orange50Total Dry Film Thickness 总干膜厚350Painting should be done by Airless Spray and Stripe Coating should be done with a brush prior to each Coat.喷涂方式采用高压无气喷涂，做每层油漆前边、角、焊缝、难以达到喷涂质量要求部位要进行预涂。C.铝质件Aluminium partVTA538蚀刻底漆Etch primer 黄色Yellow6轻扫砂或砂纸打磨Slightly sweep blast or sand paper abrade1Intergard 269（EGA088/089）环氧底漆Epoxy Primer红色Red402Interseal 670 HSEGA 236/EGA247低表面处理环氧树脂漆Surface Tolerante Epoxy灰色Grey1603I
