Introduction产品简介
3M清洗剂HFE-72DE是由HFE-7200、HFE-7100，反式二氯乙烯组成。在混合溶剂中反式二氯乙烯分别和HFE-7100和HFE-7200两种氟醚化合物形成共沸物。HFE-72DE混合物蒸汽脱脂，分析其组分很少改变，而且十分安全，能够有效的去除中等、重度清洗。
HFE-72DE广泛应用于各种清洗。HFE-72DE用于替代臭氧破坏物质、氯化溶剂等对环境、健康有影响或不安全的的清洗剂。HFE-72DE不会破坏臭氧，对环境友好。HFE-72DE表面张力低，不燃而且十分稳定，所以应用于浸洗或者气相清洗，来去除助焊剂残留和脱脂，还可以作为涂层的溶剂和分散剂。
3M Novec 72DE Engineered Fluid is a blend of methyl nonafluorobutyl ether (C4F9OCH3), ethyl nonafluorobutyl ether (C4F9OC2H5), and trans-1,2-dichloroethylene (t-DCE). In this mixture of solvents the t-DCE forms azeotropes with each of the hydrofluoroether components. The blend has been analyzed during evaporation and extended use in a vapor degreaser and found to have a consistent composition that is safe ?and effective for medium- to heavy-duty degreasing applications.
Novec 72DE fluid is ideal for a wide range of cleaning applications. It is intended to replace ozone depleting and chlorinated solvents as well as other solvent systems that do not have as favorable health, safety, or environmental properties. This Novec product has zero ozone depletion potential and other favorable environmental properties (see Table 2). 3M Industrial Hygiene monitoring indicates there is a large margin of safety between the exposure guidelines that have been established for each of the components and exposures anticipated from intended end-use applications. The high solvency and low surface tension, nonflammability and stability of Novec 72DE fluid make it ideal for immersion and vapor degreasing applications. These properties also make the solvent ideal for certain coating and lubricant deposition applications where increased solvency is desired.
