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。
3M Novec 71DA Engineered Fluid is a hydrofluoroether, Methyl Nonafluorobutyl Ether (***F9OCH3), in an azeotrope formulation with trans-1,2-dichloroethylene (t-DCE) and ethanol. This mixture is a true azeotrope, with c***tant vapor and liquid composition at its boiling point.
Novec 71DA fluid is ideal for defluxing and degreasing tasks and is intended to replace ozone-depleting materials in many applicati*** as well as certain aqueous cleaning processes and solvent coating applicati***. This Novec product has zero ozone depletion potential and other f***orable environmental properties (see Table 2).
Novec 71DA fluid has a recommended time-weighted ***erage exposure guideline of 750 ppm for the 3M Novec 7100 Engineered Fluid component (eight hour ***erage), 200 ppm for trans-1,2-dichloroethylene (t-DCE) and 1000 ppm for ethyl alcohol. These exposure guidelines suggest there is a large margin of safety for use of Novec 71DA fluid in its intended cleaning applicati***.
The increased solvency and low surface tension, nonflammability and c***tant composition during boiling of Novec 71DA fluid make it ideal for immersion defluxing and degreasing applicati***. The ethanol component of Novec 71DA fluid provides enhanced removal of ionic contaminants.
