摘要
用传统方法粉碎废旧轮胎制得胶粉时会出现高能耗、易污染、设备复杂等问题，为避免上述问题，基于高压水射流技术，设计了一套子午线轮胎回收试验装置，并安排了L25（5）3正交试验。试验得出了影响胶粉粉碎效率的主次因素，得到了最优射流工作参数为A4B4C4，还对高压水射流作用在轮胎橡胶层上的粉碎机理进行了分析，试验证明：用正交试验法所决定的最优射流工作参数是可行的，冲击粉碎和水楔粉碎是橡胶层粉碎的最重要机理。
High energy consumption, air pollution, complex equipment, and etc. occun＇ed when old tires were pulverized using traditional method. To solve these problems, a set of equipment for recycling old radial tires was designed based on the high pressure water jet. The L25（5）3 orthogonal experiments were performed. The main and secondary factors that affected the crushing efficiency of rubber powder were obtained. The optimal jet parameter was A4B4C4. Meanwhile, the crushing mechanism of high pressure water jet crushing on the tire rubber was analyzed. The experiment results showed that the optimal jet parameter was feasible via the orthogonal experiment. The impact and water wedging were the most significant rubber crushing mechanism.
