| 中文摘要: |
| 以9.00-20 14PR轮胎为试验对象,通过对多条轮胎在不同硫化时间下的温度测定,发现其最低受热部位是胎面下层;硫化温度测定值的标准偏差为±3 ℃,变异因数小于2%;不同硫化时间下轮胎在升温和温度保持阶段都有较好的一致性,冷却阶段的降温速率大致相同;平行于降温曲线可以引出任意条硫化时间不同的测温曲线,以确定过硫化轮胎硫化时间的缩短量。 |
| 英文摘要: |
| The temperature measurements were made on many 9.00-20 14PR tires with different curing periods. It was found that the lowest temperature during vulcanization occurred in the tread base ;the standard deviation for the temperature measurement was ±3 ℃,and the variation coefficient was smaller than 2%;the temperature rises and retentions of tire with different curing periods were in accordance with each other ,and their temperature downdrops during cooling were similar ;the different measured temperature curves with any curing period ,which were parallel to the measured temperature downdrop curve ,could be derived to determine the reduction of curing time. |
