| 中文摘要: |
| 分析了有转子硫化仪测试胶料硫化特性时出现的第1次试验时间滞后现象。实验分析和传热分析计算得出，硫化仪模腔充满空气时的转子表面温度比充满胶料时低，从而导致硫化仪第1次试验胶料的硫化速度慢，表现为胶料硫化特征时间(ts1，t10，t50和t90等)滞后。在试验前延长硫化仪模腔保温时间可缩短第1次试验的滞后时间。 |
| 英文摘要: |
| The delay phenomenon on the rheometer in testing the curing behavior of rubber compound at the first time was analysed.It was found from the experiment analysis and heat transfer analysis that the temperature on the rotor surface in the rheometer mold cavity filled with air was lower
than that filled with rubber compound resulting in the slower cure of rubber compound on the rheometer in the first test and the delayed times for curing characteristics (ts1，t10，t50和t90 etc.).The delayed times could be reduced by lasting the temperature rising time of rheometer mold cavity before the test. |
