输送带热硫化修补
Heat vulcanizing repair of conveyor belt
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 damage of the conveyor belt, along the damage around at least 15-20 mm, draw a cutting repair line, 45 degrees angle oblique cut, and strip the damaged glue cover, cutting 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 the conveyor belt with angle grinder and tungsten steel grinding dish is recommended. 3 mm grinding is recommended.
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. Place the grinded conveyor belt on the fabric or steel wire reinforcement layer, brush the heat vulcanizing agent on the reinforcement layer and the damaged part, cut the periphery of the unvulcanized core rubber into a bevel, and also brush the heat vulcanizing agent (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. use hot vulcanizer or vulcanizing machine to pressurize and heat vulcanize.
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 reminder: curing machine controller temperature control in 145 - 150 degrees Celsius, until the upper and lower two curing board temperature are stable, start curing time 35 - 45 minutes. (Depending on the thickness of the belt, each vulcanized board can vulcanize about 1 mm rubber every 4 minutes.) When the vulcanized board temperature drops below 70 degrees Celsius, the hydraulic pressure of the vulcanizing machine can be relieved, and then the vulcanizing machine can be removed.
