单层芯DPP芳纶输送带指形接头的研究

Study on Finger Joint of Single Core DPP Aramid Fiber Conveyor Belt

对DPP芳纶输送带指形接头进行试验研究,考察指长、指宽、接头芯胶粘合强度、加强织物层、硫化工艺和操作过程对DPP芳纶输送带静态接头强度的影响。结果表明:指形接头强度与指形自身的强度有关,指形自身强度取决于其指长与指宽;提高接头芯胶的粘合强度可提高接头强度;覆盖胶和芯胶强度越高、老化性能越好,接头越不容易开裂。

In this study, the finger joint of DPP aramid fiber conveyor belt was tested, and the effects of finger length and width ,adhesion strength of joint compound, reinforcing fabric layer, curing condition and operating process on the static strength of joint of DPP aramid fiber conveyor belt were investigated. The results showed that,the strength of finger joint depended on length and width of the finger;increase of the adhesion strength of joint core compound could improve the strength of the fin- ger joint; with higher strength of cover compound and core compound, the aging resistance was better and cracking resistance of the finger joint was better.
