电镀常见故障原因与排除

清水混凝土的配合比设计中，要针对当地水泥、砂石、外掺料及外加剂等原材料影响混凝土质量的多种因素进行分析，确定主要控制因素，并从经济性和使用要求综合考虑，优选出符合生产条件的最优方案组合。obstacles,correctingmisunderstandings,advocategoodcadrestyle.2,adheretothescientificdecision-makinganddemocraticdecision-makingdecision-makinglaw.Correctlyhandletoensurethatgovernmentdecreesandbasedontheactualcreativework,givingfullplaytosubjectiveinitiative,putanendtoimplementtheconferencemeeting,todocumenttheimplementationofdocumentsetc.Improvethescientificanddemocraticdecision-makingmechanism,improveandimplementthedecisiontosolicittheviewsofexperts,thepublichearingsystem.Improvetheimportantdecisionofriskassessmentmechanismandlegalreviewmechanism.3,topromoteteamunity.Upholdandimprovethesystemofannualpartybooktalkhearttoheart,mindandPartymembers,Partymemberstoexchangeeachothernotlessthan2times.Theimplementationofsoundteamdemocraticlifesystem,consolidateandenhancetheparty'smasslineeducationalpracticewillpromotetheachievementofthetopicofdemocraticlife,criticismandself-criticismnormalization,along-term.Adheretothepartyonthebasisoftheprincipleofunity,enhanceinternalcommunication,strengtheninternalsupervision,selfSleepmaintenanceteamcollectiveimageandauthority.(three)toensuretheexecutionisnotstrongordisguisedtoresistgovernmentdecreesissues.IndividualBureauleadershipteammemberslackoflearningpoliticaltheorysystem,notfromtheobjectivereality,notwiththeparty'sinterestsabovealltheprinciplestodealwithpersonalproblems.Inthespecificworksafetysupervisionintheexecutionisnotstrong,intheimplementationofthedecisiontodeploythediscount,makechoices,engageinwork,theimplementationoftheagreement,uncomfortableisnotperformed,openordisguisedtoresist,thelackofsubjectconsciousnessofthepartyorganization,thelackofresistinsocietyallkindsofbadhabitsandunwholesometendenciesofcourageGasandcourage.Suchastheliabilityinsuranceofsafeproductionwork,individualleadersthathavesomeonearrested,andnofunding,notintheglobalchessperspectivetothecountrysidetocarryoutdailyinspection,foundnoneofmybusinessacceptanceoftheresumptionofproductioninanarmchair,withapen,indifferent.Correctivemeasures:(LEDLeadership:LuoMingjun,rectificationtime:beforeSeptember25th,insistforalongtime)1,tostrengthenthesenseofresponsibility,worktosolvethelackofdecentoccupationexplainaway,conductproblems.Toestablishtheoverallconcept,eliminatedepartmentalism.Strictassessmentandaccountability,tosolvethespiritualslack,nianqingpazhong,statusquo,Toestablishandperfectthemuddlealongandotherissues.Bureaustaffconductworkregulations,standardizethebehaviorofpersonnel.2,strengthentheresponsibilitysystem.Oneisthein-depthstudyandimplementtheHunanprovincialPartyandgovernmentleadingcadresInterimProvisionsontheworksafetyofapairof(HunanOfficeissued2013No.常见故障原因与排除碱铜常见故障原因与排除方法故障现象故障原因排除方法结合力不好1.镀前除油不彻底2.酸活化时间太短或活化液太稀3.镀铜液中游离氰化钠过高或过低4.镀液温度过低5.电流密度太大6.镀铜液中有较多六价铬离子1.加强前处理2.调整活化酸3.分析成分,调整至正常范围4.提高温度5.降低电流密度6.加温至60℃,加入保险粉0.2-0.4克/升,搅拌20-30分钟,趁热过滤镀层粗糙色泽暗红1.温度太低2.阴极电流密度太大3.阳极面积太小4.游离氰化钠太低5.有金属锌\铅杂质6.镀液中碳酸盐含量过高1.提高温度2.降低电流密度3.增加铜板或铜粒4.分析含量,补充至正常范围5.先调整氰化钠正常含量,加入0.2-0.4克/升硫化钠,加入1-2克/升活性炭,搅拌20-30分钟,静止过滤6.加温60-70℃,在搅拌下加入氢氧化钙,搅拌30分钟,静止过滤镀层有针孔1.基体表面粗糙2.镀液有油或有机杂质3.铜含量过低或氰化钠含量过高4.阴极电流密度过大5.阳极面积太小1.加强抛光2.活性炭粉处理3.分析成分,调整正常范围4.降低电流密度5.增加阳积面积沉积速度慢深镀能力差1.阴极电流密度太小2.阳极钝化或阳极面积太小3.游离氰化钠太高4.溶液中有铬酸盐1.提高电流密度2.增加阳极面积或提高氰化钠或提高镀液温度3.调整成分4.同上处理方法镀层疏松孔隙多1.阳极钝化2.镀液中碳酸盐过多或有粘胶状的杂质3.锌-铝合金基体中铝含量过高1.同上处理方法2.同上处理方法3.要经过二次浸锌后再进行镀铜酸性镀铜常见故障原因与排除方法故障现象故障原因故障排除方法镀层发雾或发花1.前处理不良,零件表面有油2.清洗水有油或镀液有油3.光亮剂没有搅均匀或B剂太多4.镀液中有大量的铁杂质5.阳极面积太小或太短6.有机杂质太多1.清除表面油脂2.保持清洗水清洁3.搅均镀液4.加入30%双氧水1-2毫升/升,搅拌下加入氢氧化铜,加入1-2克/升活性炭,搅拌过滤5.增大面积,加长阳极6.用双氧水-活性炭处理低电流区镀层不亮1.预镀层低区粗糙2.挂具导电不良3.光剂A含量偏低4.镀液中一价铜较多1.加强预镀层质量2.检查挂具导电性3.补加A刘4.添加30%双氧水0.03-0.05毫升/升清水混凝土的配合比设计中，要针对当地水泥、砂石、外掺料及外加剂等原材料影响混凝土质量的多种因素进行分析，确定主要控制因素，并从经济性和使用要求综合考虑，优选出符合生产条件的最优方案组合。obstacles,correctingmisunderstandings,advocategoodcadrestyle.2,adheretothescientificdecision-makinganddemocraticdecision-makingdecision-makinglaw.Correctlyhandletoensurethatgovernmentdecreesandbasedontheactualcreativework,givingfullplaytosubjectiveinitiative,putanendtoimplementtheconferencemeeting,todocumenttheimplementationofdocumentsetc.Improvethescientificanddemocraticdecision-makingmechanism,improveandimplementthedecisiontosolicittheviewsofexperts,thepublichearingsystem.Improvetheimportantdecisionofriskassessmentmechanismandlegalreviewmechanism.3,topromoteteamunity.Upholdandimprovethesystemofannualpartybooktalkhearttoheart,mindandPartymembers,Partymemberstoexchangeeachothernotlessthan2times.Theimplementationofsoundteamdemocraticlifesystem,consolidateandenhancetheparty'smasslineeducationalpracticewillpromotetheachievementofthetopicofdemocraticlife,criticismandself-criticismnormalization,along-term.Adheretothepartyonthebasisoftheprincipleofunity,enhanceinternalcommunication,strengtheninternalsupervision,selfSleepmaintenanceteamcollectiveimageandauthority.(three)toensuretheexecutionisnotstrongordisguisedtoresistgovernmentdecreesissues.IndividualBureauleadershipteammemberslackoflearningpoliticaltheorysystem,notfromtheobjectivereality,notwiththeparty'si
