Introduction產品簡介

3M清洗劑HFE-71IPA是由HFE-7100和IPA組成的共沸物。HFE-71IPA可以替代CFC-113，HCFC-141B和TCA-1,1,1等破壞臭氧的物質，用于清洗一些輕微的油污。HFE-71IPA不會破壞臭氧，對環(huán)境友好。HFE-71IPA急性毒性較小，暴露極限達750ppm。

HFE-71IPA對于一些急性油污，低表面張力，不燃等特性，沸騰時，可以很好的去除和漂洗顆粒粉塵、手指印和金屬、塑料、玻璃上的輕度油污。
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（典型應用）

Precision cleaning, rinsing and drying agent.精密清洗，漂洗及干燥 
Light-duty cleaning of oils, greases, waxes, fingerprints.輕度油污、油脂、蠟及手指印的清洗 
Use in combination with co-solvents for “no-clean flux” residue removal.共溶清洗系統(tǒng)去污難以清洗的免洗助焊劑殘留（針對一些很難清洗的污染物，諸如重度油污、油脂和蠟，NOVEC HFE系列清洗劑和碳氫化合物組合清洗可以發(fā)揮更好的清洗效果,在這個清洗系統(tǒng)中包括2種溶劑：低揮發(fā)的有機溶劑將污物從表面溶解下來，3M NOVEC HFE-7100，HFE-7200和HFE-71IPA則進行表面漂洗，將前面的溶劑和未清洗掉的污物從部件上去除。Novec HFE和碳氫溶劑的清洗液具有適度的相容性，具有優(yōu)秀的清洗液使用后的漂洗特性，可以達到幾乎不殘留清洗液的功效。而且，清洗槽內被Novec HFE的蒸汽覆蓋，具有不燃性非常安全，對裝置和周邊的機械的影響很小，對裝置小型化，省空間化有一定的貢獻。）
