润滑油脂在高温环境下,其性质会不会发生改变


Release time:

2025-12-16

高温润滑油和润滑脂物理形态不一样,应用工况和性能会不一样。在工业机械应用上时,或者长期处于高温环境转态下,时间久了也会发生质量变化。
润滑脂通常是半固体软膏状的,与液态润滑油相比较,润滑脂的可使其很好地粘滞和保持在机械的润滑部位,不会流失,从而润滑方式简单方便。缺点是润滑脂在储存中和使用中比润滑油更易发生质量变化。
那么,如何更能了解高温转态下润滑油脂的质量变化情况呢?
一、很多润滑工况上,润滑脂是与空气接触的,其氧化造成润滑脂的质量变异。高温润滑脂含有皂基稠化剂,属于易氧化基,因此润滑脂比润滑油易于氧化变质。
二、通常润滑油脂是是70%~90%的润滑油和10%~30%的固态稠化剂组成。使用中润滑油脂的变质与它们的结合稳定性有重要关系。如果融合的结构不好、不稳定。从而使润滑油从体系中分离,形成所谓的分油,使润滑脂的性能下降而失去润滑脂的润滑作用。
三、润滑脂在使用中会有一些机械杂质主要是磨粒固体杂质,这些机械杂质对机械的润滑有很大的破坏,会造成润滑部件严重磨损。
四、润滑脂在机械使用中会水分的混入,会影响润滑脂的结构变化,使润滑性能下降;同时水分也会腐蚀机械,水分也会使稠化剂起到溶解和稀释作用,降低稠化剂能力,使得润滑脂变稀和发生色泽变化。
润滑脂甚至一些高温润滑脂的使用中应最限度注意这些情况发生,特别是高温润滑脂,因为在高温下,这些变质会更加易于发生。对于高温脂,在使用中对于润滑脂的观察密度要大,换脂的周期要尽量短。不然引起机械故障而不能运转。其造成的生产效益损失远大于换脂的成本。
