对丁腈橡胶(NBR)试样在100℃空气中的老化以及在氩气氛围中在较高温度(150℃和100℃)下快速老化后的有效黏度和用毛细管黏度计测定的门尼黏度进行了对比试验研究。研究结果表明,两种试样的有效黏度都具恒定性,试验数据有可比性。由此可以得出结论,在氩气氛围中在较高温度下的快速老化的试验方法对NBR试样黏度的测定是很适合的。
Aging of nitrile butadiene rubber (NBR) specimens in air at 100 ° C and effective viscosities after rapid aging at elevated temperatures (150 ° C and 100 ° C) in an argon atmosphere and Mooney viscosity as determined with a capillary viscometer A comparative experimental study was carried out. The results show that the effective viscosity of both samples are constant, the test data are comparable. From this it can be concluded that the rapid aging test method at higher temperatures in an argon atmosphere is well suited for the determination of the viscosity of NBR samples.
