| 输送带接头处的强度比正常带体的强度要低。一般用机械方式连接时，接头强度仅能达到带体强度的40－50％，冷胶方式质量比较好时，接头强度能达到60－70％，而热胶接头强度能达到80－90％（接头方法正确、无质量缺陷）。由于接头部位的强度比较低，如果胶接方法不正确，接头的强度就会更加低，如开刀、打磨时伤及下一层布、打磨过度、搭接长度不够、台阶个数不够、胶接头所用橡胶性能不好或已经自硫失效、钢丝绳打磨过度、钢丝绳生锈等，接头部位的强度将会大打折扣，在使用时，容易出现接头部位断开的现象。 The strength of the joint of the conveyor belt is lower than that of the normal belt. Generally speaking, the strength of the joint can only reach 40-50% of the strength of the strip, 60-70% of the strength of the joint can be achieved when the quality of the cold glue is better, and 80-90% of the strength of the hot glue joint can be achieved when the quality of the joint is better. Because the strength of the joint is relatively low, if the bonding method is not correct, the strength of the joint will be even lower, such as knife, grinding injury and the next layer of cloth, grinding excessive, lapping length is not enough, the number of steps is not enough, the rubber used in the joint is not good or has been self-sulfur failure, wire rope grinding excessive, wire rope rust. The strength of the joint will be greatly discounted, and it is easy to break the joint when used. 此外，输送带如果不采用封口胶、或胶接头的方向错误时，接头部位容易出现开裂（面胶部位）。 In addition, if the conveyor belt does not use sealing glue, or the direction of the joint is wrong, the joint site is easy to crack (glue part). |
