Bubble Point Method to Verify Influence of Rim Protectors on Determining Vulcanization Time of Tires

采用发泡点法验证轮辋护胶对判定轮胎最佳硫化时间的影响。结果表明:有轮辋护胶的轮胎硫化最薄弱点虽然在轮辋护胶附近,但是利用轮辋护胶最大厚度计算硫化时间并不精确,使用本工作建议位置的厚度计算的硫化时间更精确。建议在轮胎硫化厚度数据统计工作中添加有无轮辋护胶一项,并测量轮辋护胶建议位置处的厚度,可得到更精确的发泡点时间。

The bubble point method was used to verify the influence of rim protectors on determining the optimum vulcanization time of tires.The results showed that although the weakest point of vulcanization for tires with rim protectors was near the rim protector,it was not accurate to calculate the vulcanization time using the maximum thickness of the rim protector,and the vulcanization time calculated using the thickness of the recommended points in this work was more accurate.It was recommended to add the presence or absence of rim protectors in the tire vulcanization thickness data statistics work,and measure the thickness of recommended points at the rim protector to obtain a more accurate bubble point time.
