Introduction产品简介
3M清洗剂HFE-71IPA是由HFE-7100和IPA组成的共沸物。HFE-71IPA可以替代CFC-113，HCFC-141B和TCA-1,1,1等破坏臭氧的物质，用于清洗一些轻微的油污。HFE-71IPA不会破坏臭氧，对环境友好。HFE-71IPA急性毒性较小，暴露极限达750ppm。
HFE-71IPA对于一些急性油污，低表面张力，不燃等特性，沸腾时，可以很好的去除和漂洗颗粒粉尘、手指印和金属、塑料、玻璃上的轻度油污。
3M Novec 71IPA Engineered Fluid is a hydrofluoroether, methoxy-nonafluorobutane
(C4F9OCH3), in an azeotrope-like formulation with isopropanol.
This fluid is ideal for light-duty cleaning and degreasing tasks, and is intended to replace
ozone-depleting materials such as CFC-113, HCFC-14lb and 1,1,1-trichloroethane in
many applications. It has zero ozone depletion potential and other favorable
environmental properties (see Table 2). Novec 71IPA fluid has a low toxicological profile,
with a time-weighted average exposure guideline of 750 ppm for the 3M Novec 7100
Engineered Fluid component (eight hour average).
The increased polar soil solvency and low surface tension, nonflammability and constant
composition during boiling of Novec 71IPA fluid make it ideal for precision and specialty
cleaning and rinsing for removal of particulate, fingerprints and light soils from metal,
plastic and glass parts.
Typical Applications（典型应用）
Precision cleaning, rinsing and drying agent.精密清洗，漂洗及干燥
Light-duty cleaning of oils, greases, waxes, fingerprints.轻度油污、油脂、蜡及手指印的清洗
Use in combination with co-solvents for “no-clean flux” residue removal.共溶清洗系统去污难以清洗的免洗助焊剂残留（针对一些很难清洗的污染物，诸如重度油污、油脂和蜡，NOVEC HFE系列清洗剂和碳氢化合物组合清洗可以发挥更好的清洗效果,在这个清洗系统中包括2种溶剂：低挥发的有机溶剂将污物从表面溶解下来，3M NOVEC HFE-7100，HFE-7200和HFE-71IPA则进行表面漂洗，将前面的溶剂和未清洗掉的污物从部件上去除。Novec HFE和碳氢溶剂的清洗液具有适度的相容性，具有优秀的清洗液使用后的漂洗特性，可以达到几乎不残留清洗液的功效。而且，清洗槽内被Novec HFE的蒸汽覆盖，具有不燃性非常安全，对装置和周边的机械的影响很小，对装置小型化，省空间化有一定的贡献。）
