选用丁腈橡胶(NBR)5080F、5180F、2-5019,分别在10号和15号航空液压油中进行耐油试验,试验数据的对比分析表明,丁腈橡胶在15号航空液压油中的质量变化率△m和体积变化率△v全部高于在10号航空液压油中的质量变化率△m和体积变化率△v,表明其在15号航空液压油中的溶胀较大。
NBR 5080F, 5180F and 2-5019 were selected for oil resistance test in aviation hydraulic oil of No. 10 and No. 15 respectively. The comparative analysis of the test data shows that the mass change of nitrile rubber in No. 15 aviation hydraulic oil The rate of change Δm and the rate of change of volume Δv were all higher than those of mass change Δm and volume change Δv in hydraulic oil No. 10, indicating that they swelled significantly in No. 15 aviation hydraulic oil.
