| 氟化石墨是重要的无机非金属材料，具有优良的润滑性，美国和日本研究表明，氟化石墨润滑性能优于通用的石墨和二硫化钼，在干燥或潮湿高温时（400-500度）摩擦系数更小，使用寿命更长。由于氟化石墨的表面能低，它经常与润滑油、润滑脂或树脂混合使用，还可把氟化石墨粉末悬浮在润滑油中或加到汽油中去。最近几年，在飞机、轿车的发动机上有用氟化石墨做润滑剂的趋势。 Graphite fluoride is an important inorganic non-metallic material with excellent lubricity. Research in the United States and Japan shows that the lubricity of graphite fluoride is better than that of common graphite and molybdenum disulfide, and its friction coefficient is smaller and its service life is longer when it is dry or humid at high temperature (400-500 ℃). Because of its low surface energy, it is often mixed with lubricating oil, grease or resin, and can be suspended in lubricating oil or added to gasoline. In recent years, the trend of using graphite fluoride as lubricant in the engine of airplane and car. |
