1. the ratio of nitrogen-adsorption on the carbon black surface is recommendatory test index.
2. 300% stretching stress is to get the carbon black disparity between the everyday carbon black (srb3#) sample and the standard in the same experimental situation, with i type and dumbbell type reamer set by gb/t528. the vulcanization of the carbon black lasts 30 minutes under the average temperature of (145±1) .
3. all the technical indicators are taken as that of qualified products.
