【 摘 要 】

The present study was conducted to obtain a better understanding of the variation rule of shear pressure properties of tetrafluoro skateboard rubber bearings under nitric and sulphuric acids Condition. A total of 5 specimens were processed in a nitric and sulphuric acids PH4.5, and one specimen was in natural state. The parameter mainly considered time of nitric and sulphuric acids aging processing for specimens. The shear pressure capacity, ultimate shear pressure strength and shear pressure elastic modulus of tetrafluoro skateboard rubber bearings decreased dramatically. The attenuation models conform to reality well which shows that this model is applicable and has vast prospect in assessing the performance of tetrafluoro skateboard rubber bearings under nitric and sulphuric acids condition.
