各种天然的和合成的有机液体和塑性潤滑剂在解决机械工业的各种潤滑問題上愈来愈受到它們的热安定性的限制。这些潤滑材料本身在較高溫度下(例如在400℃或以上)便迅速揮发、分解或生成有害的化学反应产物从而失去了它們的潤滑作用。在无法提供高溫潤滑剂的情况下,机械工程师們不得不从机械設計上解决必須在高溫下工作的摩擦部
Various natural and synthetic organic liquids and plastic lubricants are increasingly limited by their thermal stability in solving various lubrication problems in the machinery industry. These lubricating materials themselves rapidly volatilize, decompose or generate harmful chemical reaction products at higher temperatures (for example at 400 ° C or above), losing their lubricating effect. In the absence of high-temperature lubricants, mechanical engineers have had to mechanically solve the friction that must work at high temperatures
