中水对循环水处理剂缓蚀效果影响的实验研究 Title:ExperimentalStudyontheInfluenceofFreshwaterontheCorrosionInhibitionEfficiencyofRecirculatingWaterTreatmentAgents 1.Introduction Invariousindustrialapplications,recirculatingwatersystemsareextensivelyusedforcoolingandotherprocesses.However,thesesystemsarepronetocorrosion,leadingtodecreasedefficiency,increasedmaintenancecosts,andpotentialenvironmentalconcerns.Corrosioninhibitorsarecommonlyemployedtominimizecorrosionratesandenhancetheoverallperformanceoftherecirculatingwatersystems.Thisstudyaimstoinvestigatetheeffectsoffreshwateronthecorrosioninhibitionefficiencyofrecirculatingwatertreatmentagents. 2.CorrosionInhibitionMechanisms Corrosioninhibitorsfunctionthroughadsorptionontothemetalsurface,creatingaprotectivefilmthatpreventsthecorrosiveattackofthewater.Differentchemicalcompoundsactbydifferentmechanisms,suchasformingapassivationlayerorinhibitingspecificcorrosionprocesses(e.g.,anodicorcathodicreactions). 3.ExperimentalMethodology 3.1SamplePreparation Samplesofcommonlyusedrecirculatingwatertreatmentagentswereobtainedandcharacterizedfortheirchemicalcompositionandinhibitorconcentrations.Freshwatersampleswerecollectedfromalocalsourceandanalyzedforitsphysicochemicalparameters. 3.2CorrosionAnalysis Corrosionexperimentswereconductedusingastandardizedsetupconsistingofmetalliccouponsimmersedinrecirculatingwatersystems.Electrochemicaltechniquessuchaspotentiodynamicpolarizationandelectrochemicalimpedancespectroscopywereemployedtoevaluatethecorrosionbehaviorofthemetalcoupons. 3.3CorrosionInhibitionEfficiencyMeasurement Thecorrosionrateandinhibitionefficiencywerecalculatedbasedoncorrosioncurrentdensityandpolarizationresistanceobtainedfromelectrochemicaltests.Couponstreatedwiththerecirculatingwatertreatmentagentswerecomparedwithuntreatedcouponsandcouponssubjectedtofreshwaterwithoutinhibitors. 4.ResultsandDiscussion 4.1CharacterizationofRecirculatingWaterTreatmentAgents Thechemicalcompositionandinhibitorconcentrationsoftherecirculatingwatertreatmentagentsw
