1.根据输送带破损大小，沿破损四周至少大出15~20mm，划出切割修补线，以45度角斜切，并剥去已损坏的盖胶，切割时注意不要损伤下面的布层或者钢丝层。
1. According to the breakage size of the conveyor belt, at least 15-20 mm larger along the periphery of the breakage, cut the repair line obliquely at 45 degrees, and strip the damaged cover glue. When cutting, pay attention not to damage the underlying cloth or steel wire layer.
2.将输送带破损部位用角磨机配合钨钢打磨碟进行深层次打磨，建议打磨3mm。
2. Deep grinding of the damaged parts of conveyor belt with angle grinder and tungsten steel grinding dish is recommended. It is recommended to grind 3 mm.
3.将打磨好的输送带铺上织物加强层或者是钢丝加强层，对加强层、破损部位进行涂刷热硫化剂，将未硫化芯胶四周边切成斜口，同样进行热硫化剂的涂刷平铺(未硫化面胶大小要与破损部位的大小一致)。
3. Lay the sanded conveyor belt with fabric reinforcement layer or steel wire reinforcement layer, brush the reinforcement layer and damaged parts with heat vulcanizing agent, cut the periphery of the unvulcanized core rubber into bevels, and apply heat vulcanizing agent on the same layer (the size of the unvulcanized surface rubber should be the same as the size of the damaged part).
4.使用热硫化修补器或硫化机进行加压、加温硫化。
4. Pressure and temperature vulcanization with hot vulcanization patch or vulcanization machine.
温馨提示：硫化机控制器温度控制在145—150℃之间，待上下两个硫化板温度都稳定好，开始硫化计时35~45分钟。(根据皮带厚度而定，每块硫化板每4分钟可硫化约1mm橡胶)待硫化板温度降至70℃以下方可解除硫化机水压，然后拆除硫化机。
Warm Tip: The temperature of the controller of the vulcanizer is controlled between 145 and 150 degrees C. When the temperature of the upper and lower vulcanizate plates is stable, the vulcanization time is 35 to 45 minutes. (According to the thickness of the belt, each vulcanized board can vulcanize about 1 mm rubber every 4 minutes.) The hydraulic pressure of the vulcanized machine can be relieved until the temperature of the vulcanized board falls below 70 C, and then the vulcanized machine can be removed.
