3MHFE-72DA清洗剂Introduction（产品简介）3M清洗剂HFE-72DA是由HFE-7100，HFE-7200，异丙醇和反式二氯乙烯组成的混合物。HFE-72DA是共沸混合物，通过分析可以看出HFE-72DA在液相和气相均保持组成比例一致。所以HFE-72DA可以应用于中等及重油污的清洗及助焊剂残留的去除。HFE-72DA是理想的电子及精密清洗剂。HFE-72DA可以替代CFC,HCFC,HFC,NPB,氯化溶剂等对臭氧有破坏，温室效应高以及对身体健康影响大的溶剂。由于添加了异丙醇和反式二氯乙烯，其溶解能力大大提高，且HFE-72DA具有低表面张力，而且十分稳定，故HFE-72DA应用于浸洗或超蒸汽气相清洗剂。在HFE-72DA中加异丙醇，可以增加其对于离子残留的清洗！3MNovecEngineeredFluidHFE-72DAisablendofhydro?uoroethermethylnona?uorobutylether(C4F9OCH3),ethylnona?uorobutylether(C4F9OC2H5),trans-1,2-dichloroethylene(t-DCE)andisopropanol.Thismixtureofsolventsisablendofazeotropes.Theblendhasbeenanalyzedduringevaporationandextendeduseinavapordegreaserandfoundtohaveaconsistentcompositionthatiseffectiveformedium-toheavy-dutydegreasingandde?uxingapplications.Novec?uidHFE-72DAisidealforawiderangeofelectronicsandotherprecisioncleaningapplications.ItisintendedtoreplaceCFCs,HCFCs,HFCs,nPBandchlorinatedsolvents.ThisNovecproducthaszeroozonedepletionpotentialandotherfavorableenvironmental,healthandsafetyproperties(seeTable2).Thehighsolvency,lowsurfacetension,non?ammabilityandstabilityofHFE-72DA?uidmakeitidealforimmersionandvapordegreasingapplications.TheisopropanolinHFE-72DA?uidprovidesenhancedremovalofioniccontaminants.TypicalApplications典型应用Cleaning,rinsinganddryingagent清洗、漂洗及干燥溶剂Cleaningofrosinsolder?uxresidues,oils,greasesandwaxes物理化学性质TypicalPhysicalProperties–Table1性质HFE-72DAFreonTEGenesolv2004AK-225ASEVertrelSMT沸点℃444529.45237冰点℃-38-42N/A-138N/A液体密度g/ml@25℃1.271.501.221.491.35表面张力1817.718.516.815.5KB值58407641N/A粘度cps@25℃0.400.650.450.610.49蒸汽压mmHg360362527414486挥发热cal/g@bp6043624150环境及安全性质EnvironmentalandSafetyProperties-Table2???????性质HFE-72DAFreonTEGenesolv2004AK-225ASEVertrelSMT臭氧破坏潜值ODP00.770.110.030温室效应系数GWP435800670400900闪点无无无无无)
