3MHFE-72DE清洗剂Introduction产品简介3M清洗剂HFE-72DE是由HFE-7200、HFE-7100，反式二***组成。在混合溶剂中反式二***分别和HFE-7100和HFE-7200两种氟醚化合物形成共沸物。HFE-72DE混合物蒸汽脱脂，分析其组分很少改变，而且十分安全，能够有效的去除中等、重度清洗。HFE-72DE广泛应用于各种清洗。HFE-72DE用于替代臭氧***物质、氯化溶剂等对环境、健康有影响或不安全的的清洗剂。HFE-72DE不会***臭氧，对环境友好。HFE-72DE表面张力低，不燃而且十分稳定，所以应用于浸洗或者气相清洗，来去除助焊剂残留和脱脂，还可以作为涂层的溶剂和分散剂。3MNovec72DEEngineeredFluidisablendofmethylnonafluorobutylether(***F9OCH3),ethylnonafluorobutylether(***F9OC2H5),andtrans-1,2-dichloroethylene(t-DCE).Inthismixtureofsolventsthet-DCEformsazeotropeswitheachofthehydrofluoroethercomponents.Theblendhasbeenanalyzedduringevaporationandextendeduseinavapordegreaserandfoundtoh***eac***istentcompositionthatissafe?andeffectiveformedium-tohe***y-dutydegreasingapplicati***.Novec72DEfluidisidealforawiderangeofcleaningapplicati***.Itisintendedtoreplaceozonedepletingandchlorinatedsolventsaswellasothersolventsystemsthatdonoth***easf***orablehealth,safety,orenvironmentalproperties.This?Novecproducthaszeroozonedepletionpotentialandotherf***orableenvironmentalproperties(seeTable2).3MIndustrialHygienemonitoringindicatesthereisalargemarginofsafetybetweentheexposureguidelinesthath***ebeenestablishedforeachofthecomponentsandexposuresanticipatedfromintendedend-useapplicati***.Thehighsolvencyandlowsurfacetension,nonflammabilityandstabilityofNovec72DEfluidmakeitidealforimmersionandvapordegreasingapplicati***.Thesepropertiesalsomakethesolventidealforcertaincoatingandlubricantdepositionapplicati***whereincreasedsolvencyisdesired.Applicati***典型应用Cleaning,rinsinganddryingagent清洗、漂洗和干燥的溶剂-Cleaningofoils,greases,waxesSpecialtysolventapplicati***特殊溶剂物理化学性质TypicalPhysicalProperties–Table1性质HFE-72DECFC-113HCFC-141BHCFC-225Ca/cbTCEPecrnPb分子式AzeotropeC2Cl3F3C2Cl2H3FC3Cl2HF5C2HCl3C2Cl4C3H7Br沸点℃434832548712171冰点℃N/A﹣35﹣103-131-86-23-110闪点NoneNoneNoneNoneNoneNoneNoneKB值5231563112990125液体密度g/ml@25℃1.281.561.231.551.441.621.35表面张力dynes/cm@25℃1917.319.316.232.329.525.9蒸汽压mmHg3503315692907418250挥发热cal/g@bp523553.334.656.450.158.8粘度cps@25℃0.450.680.430.590.540.750.49环境性质EnvironmentalPropertie-Table2性质HFE-72DECFC-113HCFC-141BHCFC-225Ca/cbTCEPecrnPb臭氧***潜值ODP00.80.10.03000温室效应系数GWP436000700180/620lowlowlow)
