轮胎硫化测温

Temperature Measurement of Tire during Vulcanization

以９－００－２０１４ＰＲ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。

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 occured 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.
