考察了炭黑含量、弯曲疲劳、热空气老化对乙炔炭黑——天然橡胶电阻率的影响。制成了电阻率为11Ωcm的导电橡胶。并对电阻率的测试方法作了某些改进。
The effects of carbon black content, bending fatigue and hot air aging on the resistivity of acetylene black-natural rubber were investigated. A conductive rubber having a resistivity of 11? Cm was produced. Some improvements have been made to the resistivity test method.
