汽车上使用的橡胶零件有100多个。为了解汽车用橡胶在大气中的老化性能,我们进行了试验。一、汽车用橡胶的基本情况汽车上用的橡胶可分为4类。(1)耐油橡胶这类橡胶以丁腈橡胶为主。丁腈橡胶有优良的耐油性。在汽车上用它来制造密封垫及油封等与油类接触的零件。(2)普通橡胶这类橡胶以天然橡胶为主。天然橡胶有
More than 100 rubber parts are used in cars. To understand the aging properties of automotive rubber in the atmosphere, we conducted a test. First, the basic situation of automotive rubber Automotive rubber can be divided into four categories. (1) Oil-resistant rubber This type of rubber to nitrile rubber-based. Nitrile rubber has excellent oil resistance. Use it in the car to make seals and oil seals and other parts in contact with oil. (2) ordinary rubber This type of rubber to natural rubber-based. There are natural rubber
