Introduction產(chǎn)品簡介 3M清洗劑HFE-71DE是由HFE-7100（九氟丁基甲醚）和反式二氯乙烯組成的共沸物。HFE-71DE是真正的共沸物，氣相和液相具有相同的成分組成。 HFE-71DE主要用于中等污物的清洗或者脫脂以及作為特殊溶劑使用。主要用于替代氟利昂對臭氧有破壞的物質(zhì)。HFE-71DE安全暴露極限可以參考HFE-7100的750ppm暴露極限以及反式二氯乙烯的200ppm的暴露極限。 由于加了反式二氯乙烯，其溶解能力得到提高，而且HFE-71DE的表面張力很低，不燃，沸騰時成分穩(wěn)定，所以HFE-71DE可以用于浸沒或者氣相清洗。HFE-71DE共沸物具有以上特點，也用途涂層和潤滑油的溶劑。 3M Novec 71DE Engineered Fluid is a hydrofluoroether, Methyl Nonafluorobutyl Ether (C4F9OCH3), in an azeotrope formulation with trans-1,2-dichloroethylene (t-DCE). This This fluid is ideal for medium-duty cleaning and degreasing tasks, as well as specialty solvent applications, and is intended to replace ozone-depleting materials in many applications. It has zero ozone depletion potential and other favorable environmental properties (see Table 2). Novec 71DE fluid has a time-weighted average exposure guideline of 750 ppm (eight hour average) for the3M Novec 7100 Engineered Fluid component, and 200 ppm (eight hour average) for trans-1,2-dichloroethylene (t-DCE). These exposure guidelines suggest there is a large margin of safety for use of Novec 71DE fluid in its intended cleaning applications. The increased solvency and low surface tension, nonflammability and constant composition during boiling of Novec 71DE fluid make it ideal for immersion and vapor degreasing applications. These properties also may make the azeotrope ideal for certain coating and lubricant deposition applications where increased solvency is required.
