Introduction產(chǎn)品簡介 3M清洗劑HFE-71DA是由HFE-7100，乙醇及反式二氯乙烯組成的共沸化合物。HFE-71DA沸騰時，蒸汽和液體組成一樣。HFE-71DA非常適合助焊劑去除和油污脫脂，主要用于替代臭氧破壞物質(zhì)，和其他水基清洗和溶劑清洗一樣。其不會破壞臭氧，對環(huán)境不會造成破壞。 3M Novec 71DA Engineered Fluid is a hydrofluoroether, Methyl Nonafluorobutyl Ether (C4F9OCH3), in an azeotrope formulation with trans-1,2-dichloroethylene (t-DCE) and ethanol. This mixture is a true azeotrope, with constant vapor and liquid composition at its boiling point.

HFE-71DA具有低表面張力，單一沸點，非常適合浸沒清洗助焊劑殘留和脫脂去污，加入乙醇，是的HFE-71DA可以很好的去除一些例子殘留。
Novec 71DA fluid is ideal for defluxing and degreasing tasks and is intended to replace ozone-depleting materials in many applications as well as certain aqueous cleaning processes and solvent coating applications. This Novec product has zero ozone depletion potential and other favorable environmental properties (see Table 2).
Novec 71DA fluid has a recommended time-weighted average exposure guideline of 750 ppm for the 3M Novec 7100 Engineered Fluid component (eight hour average), 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 applications.
The increased solvency and low surface tension, nonflammability and constant composition during boiling of Novec 71DA fluid make it ideal for immersion defluxing and degreasing applications. The ethanol component of Novec 71DA fluid provides enhanced removal of ionic contaminants.
