3M HFE-71DE清洗剂

Introduction产品简介

3M清洗剂HFE-71DE是由HFE-7100（九氟丁基***）和反式二***组成的共沸物。HFE-71DE是真正的共沸物，气相和液相具有相同的成分组成。

HFE-71DE主要用于中等污物的清洗或者脱脂以及作为特殊溶剂使用。主要用于替代氟利昂对臭氧有***的物质。HFE-71DE安全暴露极限可以参考HFE-7100的750ppm暴露极限以及反式二***的200ppm的暴露极限。

由于加了反式二***，其溶解能力得到提高，而且HFE-71DE的表面张力很低，不燃，沸腾时成分稳定，所以HFE-71DE可以用于浸没或者气相清洗。HFE-71DE共沸物具有以上特点，也用途涂层和润滑油的溶剂。

3M Novec 71DE Engineered Fluid is a hydrofluoroether, Methyl Nonafluorobutyl Ether (***F9OCH3), in an azeotrope formulation with trans-1,2-dichloroethylene (t-DCE). This
mixture is a true azeotrope, with c***tant vapor and liquid composition at its boiling point.

This fluid is ideal for medium-duty cleaning and degreasing tasks, as well as specialty solvent applicati***, and is intended to replace ozone-depleting materials in many applicati***. It has zero ozone depletion potential and other f***orable environmental properties (see Table 2). Novec 71DE fluid has a time-weighted ***erage exposure guideline of 750 ppm (eight hour ***erage) for the3M Novec 7100 Engineered Fluid component, and 200 ppm (eight hour ***erage) 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 applicati***.

The increased solvency and low surface tension, nonflammability and c***tant composition during boiling of Novec 71DE fluid make it ideal for immersion and vapor degreasing applicati***. These properties also may make the azeotrope ideal for certain coating and lubricant deposition applicati*** where increased solvency is required.
