在电力、冶金、矿山、煤炭、热加工、塑料加工等机械设备,以及民航机上采用液压技术时,由于工作温度及环境温度很高,普通液压油极易变质而丧失粘性与润滑性;温度过高时,火星溅在由系统中漏出的油液上时,或者管路破裂而油液喷到炽热的金属上时,还可能发生油液的燃烧。为防止火灾事故,从四十年代起(第二次世界大战)美国首先开始在飞机 In the power, metallurgy, mining, coal, thermal processing, plastic processing machinery and equipment, and civil aircraft using hydraulic technology, due to high operating temperature and ambient temperature, ordinary hydraulic oil can easily degenerate and lose viscosity and lubricity; temperature High, the Mars splashed oil leaked from the system, or the pipeline rupture and the oil sprayed on the hot metal, the burning of oil may also occur. From the forties (World War II), the United States first started on the plane to prevent fire accidents
