HFE-72DE電子清洗劑/精密清洗劑

Introduction產品簡介

3M清洗劑HFE-72DE是由HFE-7200、HFE-7100,反式二氯乙烯組成。在混合溶劑中反式二氯乙烯分別和HFE-7100和HFE-7200兩種氟醚化合物形成共沸物。HFE-72DE混合物蒸汽脫脂,分析其組分很少改變,而且十分安全,能夠有效的去除中等、重度清洗。

HFE-72DE廣泛應用于各種清洗。HFE-72DE用于替代臭氧破壞物質、氯化溶劑等對環境、健康有影響或不安全的的清洗劑。HFE-72DE不會破壞臭氧,對環境友好。HFE-72DE表面張力低,不燃而且十分穩定,所以應用于浸洗或者氣相清洗,來去除助焊劑殘留和脫脂,還可以作為涂層的溶劑和分散劑。

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.
