门尼黏度

随着EPDM并用量的增加，CR/EPDM共混胶料的门尼黏度随着温度的升高而降低的趋势减缓；

For CR / EPDM blends , the decreasing trend of Mooney viscosity became slower with the increase of content of EPDM in the blends .

结果表明，在60~90℃时，胶料的门尼黏度随温度升高而降低，其中纯CR胶料的下降趋势比纯EPDM和CR/EPDM胶料更为迅速；

The results showed that the Mooney viscosity of blends decreased with the increase of temperature from 60 ℃ to 90 ℃ and the decreasing trend of pure CR compounded rubber stock was faster than that of compounded rubber stocks of pure EPDM and CR / EPDM blends .

结果表明，停留时间在2min以内时其门尼黏度和不饱和度急剧下降，超过2min后的变化不大；

The results showed that the Mooney viscosity and the unsaturated degree decreased greatly with time in 2 min , but decreased slightly with time beyond 2 min ;
