HFE-71DA电子清洗剂/精密清洗剂/助焊剂清洗剂

Introduction产品简介

3M清洗剂HFE-71DA是由HFE-7100,乙醇及反式二氯乙烯组成的共沸化合物。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,主要用于替代臭氧破坏物质,和其他水基清洗和溶剂清洗一样。其不会破坏臭氧,对环境不会造成破坏。
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 (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.
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.
