Introduction（產(chǎn)品簡(jiǎn)介） 3M清洗劑HFE-72DA是由HFE-7100，HFE-7200，異丙醇和反式二氯乙烯組成的混合物。HFE-72DA是共沸混合物，通過(guò)分析可以看出HFE-72DA在液相和氣相均保持組成比例一致。所以HFE-72DA可以應(yīng)用于中等及重油污的清洗及助焊劑殘留的去除。 HFE-72DA是理想的電子及精密清洗劑。HFE-72DA可以替代CFC,HCFC,HFC,NPB,氯化溶劑等對(duì)臭氧有破壞，溫室效應(yīng)高以及對(duì)身體健康影響大的溶劑。 由于添加了異丙醇和反式二氯乙烯，其溶解能力大大提高，且HFE-72DA具有低表面張力，而且十分穩(wěn)定，故HFE-72DA應(yīng)用于浸洗或超蒸汽氣相清洗劑。在HFE-72DA中加異丙醇，可以增加其對(duì)于離子殘留的清洗！ 3M Novec Engineered Fluid HFE-72DA is a blend of hydro?uoroether methyl nona?uorobutyl ether (C4F9OCH3), ethyl nona?uorobutyl ether (C4F9OC2H5), trans- 1,2-dichloroethylene (t-DCE) and isopropanol. This mixture of solvents is a blend of azeotropes. The blend has been analyzed during evaporation and extended use in a vapor degreaser and found to have a consistent composition that is effective for medium- to heavy-duty degreasing and de?uxing applications. Novec ?uid HFE-72DA is ideal for a wide range of electronics and other precision cleaning applications. It is intended to replace CFCs, HCFCs, HFCs, nPB and chlorinated solvents. This Novec product has zero ozone depletion potential and other favorable environmental, health and safety properties (see Table 2). The high solvency, low surface tension, non?ammability and stability of HFE-72DA ?uid make it ideal for immersion and vapor degreasing applications. The isopropanol in HFE-72DA ?uid provides enhanced removal of ionic contaminants.
