1. The process of vulcanization and bonding of conveyor belts is actually a process of continuous cross-linking of vulcanized rubber. Since heating and pressure are required during vulcanization, and it takes a long time, after a long period of vulcanization, the hardness of the vulcanized rubber will increase, so the joint part will feel harder than other parts.
2. The edge glue is worn out during the deviation and causes the delamination of the cloth layer. How to deal with it?
In the case of a small delamination area, it can be repaired with cold glue, but be sure to pay attention to emptying the air. Of course, the best way is to correct the deviation of the conveyor belt when it is found.
3. How to connect two conveyor belts with the same number of layers?
In general, this method cannot be used. But in some unexpected situations, this method has to be taken when the scene needs emergency. When using this method, it is best to place a seam of one layer to two layers at the bottom, and put enough glue on the sealing glue to eliminate the influence of inconsistent thickness at both ends on the conveyor belt joint.
4. What are the advantages and disadvantages of EP belt and NN belt?
NN conveyor belt is a substitute for cotton canvas conveyor belt, which has the advantages of high strength and good fatigue resistance, but the elongation rate of NN conveyor belt is relatively large and easy to stretch during use; EP belt is an upgraded product of NN belt , it has the advantages of nylon conveyor belt, and at the same time, due to the relatively small elongation during use, it is suitable for a wider range. However, the bonding performance of EP canvas and rubber is not as good as that of NN canvas, so EP conveyor belt is not as good as NN conveyor belt in terms of safety of bonding.
