Aging of rubber parts for automobiles

Aging of rubber parts for automobiles

Answer:

Automobile rubber parts aging factors are: oxygen, ozone, heat, light, mechanical stress, moisture, oil, other chemicals or radiation, etc.. Attention should be paid to water and oil here:The alternate action of high temperature and oxygen 1. long-term water and in the external environment under the accelerated aging of rubber;2., the oil will penetrate the rubber, so that swelling occurs, rubber performance will be reduced. Therefore, trucks should avoid shock absorption of rubber bushings, oil and diesel in various occasions, including maintenance.The impact of aging on rubber shock absorber
The engine bracket, the foot pad, the leaf spring bushing, and the shock absorbing foot cushion, such as rubber aging, will vibrate abnormally and cause abnormal noise, which will cause the damage of the whole component and even the radiation to the surrounding parts. In addition, the rubber bushings on the trucks need to be replaced, it is not an easy task and sometimes requires larger actions. For example, the shock absorber rubber of the cab needs to be lifted if it needs to be replaced.
Due to the comprehensive effect of various internal and external factors, rubber products will deteriorate the chemical properties and mechanical properties of this kind of phenomenon is realized by rubber aging, cracking, sticking, hardening, powder, mold. Shute rubber reminder, especially the rubber parts on the vehicle, due to the complex use of the environment, aging accelerated more obvious.
