LF13-2油漆样板实验建议方案1规范和标准实验中所有的操作、检验规范和标准都必须满足涂装程序:SD-DOC-LF13-2-JKT-CC-0001REV0要求。2方案步骤具体施工要求详见涂装程序:SD-DOC-LF13-2-JKT-CC-0001REV0.1、对于每个油漆系统配套,至少要制备3个面积不小于1平方米的样板,材质和施工中使用的一致,针对本项目为导管架项目,建议样板采用管材,管径和项目实际管径相近。2、当环境条件和磨料符合涂装程序和油漆说明书要求后,对样板进行喷砂处理。表面处理等级、表面粗糙度和表面可溶性盐含量应满足涂装程序要求。3、当喷砂处理和环境条件满足规格书和油漆说明书要求后,按照涂层配套顺序,分别喷涂底漆,中漆,面漆。在进行下道涂装前确保前道涂层按照油漆商说明书固化。在喷涂过程中检验油漆固化时间、湿膜厚度。在涂装作业完成后,涂装表面都要进行外观缺陷检验,涂装表面不能有杂质、流挂、起泡等其它漆病。4、检测各层涂层干膜厚度、检测各层涂层附着力3油漆配套3.1SystemA系统ACoatingsystemfortheexteriorsurfaceofthesteelstructuralinsplashzone(fromEL.-3.57MtoEL.+8.0M)seetable3.1.thesteelstructuralinsplashzoneincludingjacket’slegsandbraces,cableprotector,bargebumper,landingstructure,conductorandanyothersteelsurfacesinsplashzone.导管架的飞溅区部分(EL-3.57m到EL+8.0m)钢结构外表面涂装系统见表3.1。该部分包括大腿、拉筋、电缆护管、隔水套管、靠船件、登船平台和其它任何在飞溅区的钢结构外表面。Table3.1Process程序Painttype油漆类型DryFilmThickness(m)干膜厚度Coatinginterval(23℃)涂装间隔Potlife(23℃)混合使用寿命Thinner稀料Color颜色SurfaceSurfacecleaning表面清理:SSPC-SP102preparation表面处理Surfaceprofile表面粗糙度:50~75mPrimer底漆MARATHONXHB55010h-3d45minThinner17GreyFinishcoating面漆MARATHONXHB50010h-3d45minThinner17OffshoreYellowTotalcoatingthickness涂层总厚度1050Note注释:1、Beforeeveryfullcoat,astripecoat,shouldbeappliedbybrushonalledges,corners,weldingseamsandotherareasdifficulttoreach,inordertobuildupthedryfilmthicknessontheseareas.对于焊缝、边,角等难于喷涂的区域,在喷涂前使用刷子进行预涂。2、Forlowtemperatureapplication,MarathonXHBtobereplacedwithJotamastic87GFCCsubjecttotheowner’sapproval.低温时使用Jotamastic87GFCC替换MarathonXHB。33.2SyetemB系统BCoatingsystemforexteriorsurfacesofthesteelstructuralaboveEL.+8.0mseetable3.2.Thesteelstructureofthiszoneincludelegs,pumpcaisson,cableprotector,conductors,landingstructureandanyothersteelsurfaces.导管架从EL+8.0m到顶部(飞溅区以上的部分),如大腿、泵护管、电缆护管、隔水套管,登船平台钢结构外表面涂装系统见表3.2。Table3.2Process程序Painttype油漆类型Dryfilmthickness(m)干膜厚度Coatinginterval(23℃)涂装间隔Potlife(23℃)混合使用寿命Thinner稀料Color颜色Surfacepreparation表面处理Surfacecleaning表面清理:SSPC-SP10Surfaceprofile表面粗糙度:50~75mPrimer底漆BARRIER80651.5h-unlimited12hThinner17GreySecondcoating中漆*PENGURDMIDCOATMIO2006h-unlimited2hThinner17GreyFinishcoating面漆HARDTOPXP657h-unlimited1.5hThinner10/26RAL1028Totalcoatingthickness涂层总厚度325Note注释:1、Beforeeveryfullcoat,astripecoat,shouldbeappliedbybrushonalledges,corners,weldingseamsandotherareasdifficulttoreach,inordertobuildupthedryfilmthicknessontheseareas.对于焊缝、边,角等难于喷涂的区域,在喷涂前使用刷子进行预涂。2、Forlowtemperatureapplication,PenguardMidcoatMIOtobereplacedwithPenguardExpressMIOsubjecttotheowner’sapproval.低温时使用PenguardExpressMIO替换PenguardMidcoatMIO。3、Forlowtemperatureapplication,HardtopXPtobereplacedwithHardtopASsubjecttotheowner’sapproval.低温时使用HardtopAS替换HardtopXP。43.3SyetemC系统CAllgalvanizedsurfaceoftheladders,handrails,stairtreadsandgrating,coatingsystemseetable3.3.所有梯子、栏杆、踏步和格栅的镀锌表面涂装系统见表3.3。Table3.3Process程序Painttype油漆类型DryFilmthickness(m)干膜厚度Coatinginterval(23℃)涂装间隔Potlife(23℃)混合使用寿命Thinner稀料Color颜色Surfacepreparation表面处理Surfacecleaning;SSPC-SP7表面清理:SSPC-SP7Primer底漆JOTMASTIC8010010h-unlimited2hThinner17GreyFinishcoating面漆HARDTOPXP607h-unlimited1.5hThinner10/26RAL1028Totalcoatingthickness涂膜总厚度160Note注释:1、Beforeeveryfullcoat,astripecoat,shouldbeappliedbybrushonalledges,corners,weldingseamsandotherareasdifficulttoreach,inordertobuildupthedryfilmthicknessontheseareas.对于焊缝、边,角等难于喷涂的区域,在喷涂前使用刷子进行预涂。2、Forlowtemperatureapplication,Jotmastic80tobereplacedwithJotmastic80WGsubjecttotheowner’sapproval.低温时使用Jotmastic80WG替换Jotmastic80。3、Forlowtemperatureapplication,HardtopXPtobereplacedwithHardtopASsubjecttotheowner’sapproval.低温时使用HardtopAS替换HardtopXP。53.4SyetemD系统DForinteriorsurfaceofthedrillingwatertanks,coatingsystemseetable3.4.钻井水罐内表面涂装系统见表3.4。Table3.4Process程序Painttype油漆类型DryFilmthickness(m)干膜厚度Coatinginterval(23℃)涂装间隔Potlife(23℃)混合使用寿命Thinner稀料Color颜色Surfacepreparation表面处理Surfacecleaning;SSPC-SP10表面清理:SSPC-SP10Surfaceprofile表面粗糙度:40~85mPrimer底漆TANKGURDSTORAGE12510h-30d4hThinner23LightredFinishcoating面漆TANKGURDSTORAGE12510h-30d4hThinner23LightGreyTotalcoatingthickness涂膜总厚度250Note注释:1、Beforeeveryfullcoat,astripecoat,shouldbeappliedbybrushonalledges,corners,weldingseamsandotherareasdifficulttoreach,inordertobuildupthedryfilmthicknessontheseareas.对于焊缝、边,角等难于喷涂的区域,在喷涂前使用刷子进行预涂。
