输送带接头为何容易出现裂缝、断裂？ Why are the conveyor joints prone to cracks and fractures? 输送带接头处的强度比正常带体的强度要低。普通用机械形式连署时，接头强度仅能达到带体强度的40－50％，冷胶形式品质比较好时，接头强度能达到60－70％，而热胶接头强度能达到80－90％（接头办法准确、无品质欠缺）。因为接头部位的强度比较低，假如胶接办法错误，接头的强度便会更加低，如开刀、打磨时伤及下一层布、打磨过度、搭接长度不够、阶梯个数不够、胶接头所用橡胶性能非常不好或已经自硫失去效力、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QQ，在运用时，容易显露出来接头部位断裂的现象。 The strength of the conveyor belt is lower than that of the normal band. Ordinary signatures in mechanical form, the joint strength can only reach the belt body strength of 40-50%, cold form quality is better, the joint strength can reach 60-70%, and the intensity of hot glue joint can reach 80-90% (joint method are accurate and not lack of quality). Because the strength of the joint part is lower, if bonding method error, the strength of the joint will be more low, such as surgery, the wound and the next layer of cloth, polishing too much, not enough lap length, number of steps, glue joint used rubber performance is very bad or sulfur has since lost its potency, wire rope grinding excessive, rust, etc., the strength of the joint parts will be big discount on QQ, when in use, easy to fracture phenomenon revealed joint parts.
