| 中文摘要: |
| 以乙炔炭黑和高导电炭黑填充天然橡胶，研究其在工频电流电路中的特性。结果表明：填充高导电炭黑的天然橡胶的导电性能明显优于填充乙炔炭黑的天然橡胶，高导电炭黑的适宜填充量为30份；导电天然橡胶交流电阻低于直流电阻；导致导电天然橡胶受热迅速破坏的耗散功率为20一30W，高导电炭黑天然橡胶正常使用的耗散功率不宜超过4W。 |
| 英文摘要: |
| A study was made on the behavior of NR compounds filled with acetylene black and super conductive black in the circuit of the current at the industrial frequency.The result showed that the conductivity of NR compound filled with super conductive black was significantly better than that of NR compound filled with acethlene black；the appropriate loading level of the super conductive black was 30 phr；the AC resistance of the conductive NR compound was lower than its DC resistance；the dissipation power which might result in fast desterioration of the conductive rubber by heat was 20-30W；the normal dissipation power of NR，super conductive black had better not exceed 4W. |
