水性漆施工讨论

AWX施工注意讨论AWX色漆是什么样的色漆?AWXbasecoatutilizesawaterbornebasecoatbinderresinsystemthatisprimarilycomposedofpolyurethaneparticlesandacryliclatexparticlesdispersedinwaterandco-solvents.AWX色漆系统采用了聚氨酯分散体和聚丙烯酸分散体(水性乳液)系统而制造出的水性色漆。WhatHappenswhenAWXbasecoatdries?AWX色漆是怎样干燥的？WhenAWXdehydrates,particlestoucheachother.当AWX干燥时，高分子颗粒互相接触。Thenparticlescoalesce,andmergeintoacontinuousfilm.高分子颗粒互相熔合成连续的薄膜。Particlesclosetogether高分子颗粒靠近Particlesdeform高分子颗粒变形ContinuityIncreases连续相增加CuringMechanism-Solventborne溶剂型色漆的固化机理1.Atomization空气雾化2.Solventevaporation溶剂挥发3.Viscosityincrease黏度增加4.Polymermoleculesbecomeentangledandformfilmwhentheremainingsolventdiffusesoutofthefilm.当残余的溶剂挥发出漆膜时聚合物分子链互相纠缠，从形成了漆膜。CuringMechanism-SolventborneAtomizationEvaporationFilmformationwhenpolymers溶剂挥发fusetogether雾化聚合物形成漆膜SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSThinkULTRA!考虑一下ULTRAWaterborneCuringisDifferent水性涂料挥发时不同的1.Atomization雾化2.Dehydration脱水3.Polymerparticlestoucheachother.分散体颗粒互相接触。4.Sphericalparticlesdeformintopolyhedralcells.球型颗粒变形成多面体单元。5.Withreducedamountsofwater,coalescingsolventsleftbehindstarthelpingthepolymerparticlestojointogether.随着水分挥发，助溶剂留下来帮助聚合物颗粒融合。6.Polymerparticlesarecoalescedandfusedtogetherintoacontinuousfilmwhilethecoalescingsolventsarereleased.当助溶剂挥发后聚合物颗粒彻底结合在一起。CuringMechanism-WaterborneAtomizingDehydrationPolymerparticlestoucheachother雾化脱水聚合物颗粒互相接触!考虑一下AWXAreWaterborneBasecoatsFreeofSolvents?水性涂料是否不含溶剂？Currently,thereareNObasecoatsthatarefreeofsolvent,or0VOC,forvehiclerefinish.目前所有的色漆都含有溶剂，没有一种汽车修补色漆的VOC是0。•Solventsareneededinwaterbornecoatingsfor“coalescing”thepaintfilm,i.e.,forpolymerparticlestointer-diffuseandfusetogether.水性色漆中的溶剂是必要的，例如帮助分散体互相融合成一体。CanIusetapwater?我可以用自来水吗？No.不行•AWXreducerscontainsolventsandotheringredientsthatareconducivetofilmformation.AWX稀释剂含有溶剂和其他的有助于成膜的成分。•Weuseonlyde-ionizedwaterthatispHneutralandfreeofcontaminants.我们只能用去离子水来调节PH值和清洗污染物（只在生产过程中使用）。Isthereonly1typeofwaterbornereducer?是否只有一种水性稀释剂？No.不是•Therearecurrently2reducers,differentincompositionanddryingspeed.目前使用两种稀释剂，目的是调节干燥速度。•Withcoalescingsolventsandotherchemicals,wehaveleveragetoadjustthecurerateofwaterbornesystem.使用助溶剂和其他化学物质，我们可以调节水性涂料的干燥速度。CouldIjustaddmorewater?我可以加多一点的水吗？No.不行•Additionalamountofwatermaycauselongertimetodehydrate.额外的水会延长脱水的速度。•Trappedwatercouldcauseadhesionandcohesionfailure残留的水分会导致层间附着力和附着力的丧失•Longerdehydrationtimemaycausedegradationinmetalcontrol.长时间的脱水会造成金属颜料定向控制能力退化。•PoorFilmFormation导致漆膜缺陷•PoorMetallicOrientation导致铝粉漆产生发花现象。Iswaterborneslowertodry?水性涂料是否干的很慢？Notnecessarily.不一定•AWXbasecoatiscompetitivewithcompetitivewaterbornesystems.和其他品牌相比AWX水性涂料干燥性是非常有优势的。•Whileitsdryspeedvariesgreatlywithtemperatureandhumidity,AWXbasecoatiscompetitivewithsolventbornebasecoatsundermosttypicalapplicationconditions.水性色漆的干燥取决于现场温度和湿度，AWX色漆系统在典型的施工环境下干燥速度可与溶剂型色漆媲美。•Drytotouchmaynotmeanthoroughdehydration,thereforemaynotbereadyforclearcoat.(Recommendedminimumtime–15min.)指干并不意味着彻底干燥，因此并不意味马上可以罩清漆（建议晾干时间至少15分钟以上，具体时间和方法干燥请阅读相关资料）Doesthewaterbornebasecoatneedhardener?水性色漆需要固化剂吗？Withadditionalhardenerornot,AWXbasecoatisalreadycrosslinked.无需额外固化剂，因为AWX色漆已经是交联的。•AWXbasecoatdoesnotrequiretheadditionofhardener,andyetretainsfilmtoughnessbetterthan1KUltra.AWX色漆不需要额外的固化剂，但仍然比1KUltra7000色漆要硬。•Composedofcrosslinkedpolyurethaneparticles,AWXguaranteestoughcrosslinkedfilmsaslongastheyarecoalescedwell.由于使用了交联型的聚氨酯分散体AWX色漆只要融合的很好它就能表现出交联型漆膜的特性ImportantFactorstoConsider必须考虑的重要因素Reductionratio稀释比率Reducertype稀释剂类型Flashtime闪干时间Filmbuild漆膜厚度Dropcoat干喷Forcedair强制气流Gunsetting喷枪选择Temperatureandhumidity温度和湿度Contamination清洁程度Clearcoatfilmbuild清漆膜厚必须考虑的重要因素：对AWX色漆表现力有影响施工因素现象对AWX色漆成膜的影响对漆膜性能的影响稀释比率太高延长干燥时间分层稀释剂类型太快分散体融合时间不足分层罩清漆太早溶剂和水被清漆封闭分层漆膜太厚溶剂和水被清漆封闭分层干喷太干没有溶剂帮助融合分层强制气流时间太久把助溶剂吹走鱼眼，清漆不能铺展强制气流太强烈把助溶剂吹走鱼眼，清漆不能铺展雾化压力太高在色漆被雾化时溶剂损失干喷，清漆不能铺展温度太低溶剂和水被清漆封闭分层湿度太高水被清漆封闭分层清漆太薄没有足够的异氰酸酯清漆与色漆之间没有附着力DonotOver-Reduce不要过度稀释AWX“RulesofEngagement”使用指南ApplicationGuidelinesandProcedurestoInsureSuccessTopicsofDiscussion讨论主题•Reduction稀释率•BasecoatFlashTimes闪干时间•BasecoatDryTimes晾干时间•455-0500HarmonizerUse接口树脂的使用•Clearcoats清漆•Primers底漆•Spraygun喷枪建议Recommendations•Straining/Filtering过滤•CupSystems喷枪的使用AWXReductionAWX的稀释•Theonlyreductionwhenusing0001is10%.只能用10%的0001稀释剂稀释色漆•Water/Solvententrapmentispossibleifreductionrecommendationsareexceeded.使用过多的稀释剂可能导致水/溶剂被闷在色漆中•Whenusing0002,reductionis10-20%.(Seechart)使用0002时稀释剂比例是10-20%•Using0002inlowertemperaturesandhumiditiesmayleadtoextendedflashtimesanddrytimesbeforeclearcoatapplication使用0002稀释剂会延长罩清漆之前的闪干和晾干时间。（如：在较低湿度和较高温度时）•使用0025或0035水性稀释剂时混合比例为30%。ReducerChart20C/68F27C/80F32C/90F39C/100F49C/120F40%00010001000100010002@10%35%0001000100010002@10%0002@10%30%0001000100010002@10%0002@10-20%25%0001000100010002@10-20%0002@20%20%000100010002@10%0002@10-20%0002@20%15%000100010002@10-20%0002@20%0002@20%10%00010002@10%0002@10-20%0002@20%0002@20%5%0002@10-20%0002@10-20%0002@20%0002@20%0002@20%Inwarmerconditions:Highlychromat
