【摘要】 采用ＺＬＷ型智能硫化测温仪对现行配方及工艺下９００Ｒ２０１４ＰＲ轮胎硫化过程中的温度变化进行了测定，并进一步分析了其硫化程度。结果表明，轮胎各部位胶料在现行工艺下都存在一定程度的过硫化，而且有的部位过硫化程度还相当严重（按硫化仪数据计分布在１８９％～５２３％，按平板硫化机数据计分布在４３％～２００％）。分析认为，有必要缩短现行硫化时间并对部分胶料的硫化特性进行调整更多还原

【Abstract】 The temperature change during vulcanization of 900R20 14PR tire produced with the existent formula and technique is determined by ZLW Smart Curing Temperature Detector,and the curing state of the tire is analysed.The results show that the overcure occurs more or less in various parts of tire,and quite seriously in some parts.It is considered from the analysis that it is necessary for the existent curing time to be shortened and for the curing characteristics of compounds in some parts to be adjusted.更多还原
