稠化剂量对锂基润滑脂流变性的影响

EFFECTS OF THICKER AMOUNT ON RHEOLOGY OF LITHIUM GREASE

为了考察稠化剂的量对锂基润滑脂流变性的影响,在稳态剪切流和小幅振荡剪切流下测试了锂基润滑脂的流变参数。通过分析触变性、屈服应力,表观黏度、储存模量和应变幅度等流变参数,探讨了稠化剂的量对流变性的影响。结果表明:随着稠化剂含量增加,锂基润滑脂的黏弹性表现更加显著,其结构更加稳定。

To study the influence of thicker amount on the rheological properties of lithium grease, the rheological parameters of lithium grease were tested under conditions of steady shear flow and slight oscillation shear flow. By analyzing rheological parameters such as the thixotropy, yield stress and apparent viscosity, storage modulus and strain amplitude, the influences of thicker amount on rheological property were discussed. The results indicate that with increasing thicker content, the viscoelasticity of lithium grease is more significant, the structure of lithium grease is more stable.
