要润滑脂长期不变质的,请牢记以下几点!

润滑脂变质的原因主要有两方面:一方面是化学变化,如基础油氧化变质和大量分油,以及组分中所含添加剂有效成分的减少等;另一方面是物理变化,如润滑油脂稠度的增大或减小,滴点下降等。而变质的快慢是决定润润滑油脂使用寿命的基本根据。

润滑油脂在使用过程中受热而促进其氧化变质的反应,使基础油的粘度增大,酸值增高,氧化物增加,稠化剂的结构破坏,导致润滑脂软化并大量分油而缩短使用寿命。同样地,也有因氧化变质而硬化,从金属表面上脱落,润滑脂不能再使用。因此,为了抑止或延长滑润脂的热氧化变质,都要求添加抗氧添加剂。

润滑油脂在使用过程中受到机械的揉搓和搅拌,经常处于被剪切的过程中,按其剪切安定性的好坏而造成不同程度的稠度下降,随机械的搅拌作用而使其结构破坏而导致软化并大量分油,同时由于轴颈的高速转动所产生离心力的作用,也易使基础油发生大量分油,润滑油脂变硬而不能使用。

水分可使某些润滑油脂(如钠基润滑脂)乳化变质,甚至影响使用中对金属部件的锈蚀性能。水分还可以加速润滑油脂的氧化变质,促使润滑油脂软化,稠度增大。有的试验结果表明,即或是贪1%的微量水分也对轴承油脂有不良影响。当使用环境有与水接触的,可能时必须在选用能耐水的基础油与添加剂加强油脂的耐水性,并尽量选用含防锈添加剂类的润滑脂。

使用过程中杂质的影响,润滑油脂在缓冲使用过程中进入的杂质,主要是磨损的金属微粒利落入的尘埃等。这些杂质,除对金属部件产生磨损外,还对润滑油脂的化学变质起促进作用。试验表明,即或在润滑油脂的含油量和基础油质量并无很大变化的情况下,当润滑油脂中由于磨损而产生的含铁量达到0.8%以上和含铜量达到0.7%以以上时,润滑油脂的磨损性已明显地恶化,因而不能继续使用。所以形成了油脂在长期使用过程中会出现变干涸与失效的问题。

基于以上几个变质的原因,选用油脂时一定要与生产工厂确定好应用要求及使用环境要求,再进行合理的选择,宝星特种脂的主要优势在于可根据客户的要求量身订做各类专用型油脂,这样就可以大大提升油脂的适用条件。
