3MHFE-71DA电子清洗剂/精密清洗剂Introduction产品简介3M清洗剂HFE-71DA是由HFE-7100，乙醇及反式二***组成的共沸化合物。HFE-71DA沸腾时，蒸汽和液体组成一样。HFE-71DA非常适合助焊剂去除和油污脱脂，主要用于替代臭氧***物质，和其他水基清洗和溶剂清洗一样。其不会***臭氧，对环境不会造成***。HFE-71DA具有低表面张力，单一沸点，非常适合浸没清洗助焊剂残留和脱脂去污，加入乙醇，是的HFE-71DA可以很好的去除一些例子残留。3MNovec71DAEngineeredFluidisahydrofluoroether,MethylNonafluorobutylEther(***F9OCH3),inanazeotropeformulationwithtrans-1,2-dichloroethylene(t-DCE)andethanol.Thismixtureisatrueazeotrope,withc***tantvaporandliquidcompositionatitsboilingpoint.Novec71DAfluidisidealfordefluxinganddegreasingtasksandisintendedtoreplaceozone-depletingmaterialsinmanyapplicati***aswellascertainaqueouscleaningprocessesandsolventcoatingapplicati***.ThisNovecproducthaszeroozonedepletionpotentialandotherf***orableenvironmentalproperties(seeTable2).Novec71DAfluidhasarecommendedtime-weighted***erageexposureguidelineof750ppmforthe3MNovec7100EngineeredFluidcomponent(eighthour***erage),200ppmfortrans-1,2-dichloroethylene(t-DCE)and1000ppmforethylalcohol.TheseexposureguidelinessuggestthereisalargemarginofsafetyforuseofNovec71DAfluidinitsintendedcleaningapplicati***.Theincreasedsolvencyandlowsurfacetension,nonflammabilityandc***tantcompositionduringboilingofNovec71DAfluidmakeitidealforimmersiondefluxinganddegreasingapplicati***.TheethanolcomponentofNovec71DAfluidprovidesenhancedremovalofioniccontaminants.Applicati***产品应用-Cleaning,rinsinganddryingagent;coatingsolvent清洗，漂洗，干燥以及涂层溶剂-Cleaningofoils,greases,waxes,handlingoilsandsolderfluxresidue清洗油污，油脂，助焊剂残留-Precisioncoatingofsiliconesandotherlubricants硅油及其他润滑剂的溶剂或稀释剂物理化学性质TypicalPhysicalProperties–Table1性质HFE-71DAFreonTEGenesolv2004AK-225ASEVertrel***T沸点℃404529.45237冰点℃-29-42N/A-138N/A液体密度g/ml@25℃1.331.501.221.491.35表面张力16.417.718.516.815.5KB值33407641N/A粘度cps@25℃0.450.650.450.610.49蒸汽压mmHg381362527414486挥发热cal/g@bp5043624150环境及安全性质EnvironmentalandSafetyProperties-Table2性质HFE-71DAFreonTEGenesolv2004AK-225ASEVertrel***T臭氧***潜值ODP00.770.110.030温室效应系数GWP1705800670400900闪点无无无无无HFE-71DA相关***信息)
