conveyor belt
the strength of the conveyor belt joints is lower than normal body strength. generally use mechanical means to connect, the joint strength can only be reached with 40-50% of the strength, the better the quality of the way of cold glue joint strength can reach 60-70%, while the hot glue joint strength can reach 80-90% (joint method is correct, no quality defects). relatively low intensity of the joints, if the bonding is not correct, the joint strength will be much lower, such as surgery, hurt the next layer of cloth when sanding, grinding over-lap length is not enough, the step number is not enough, the glue joints used in the performance of rubber is not good or has been invalid since the sulfur, excessive rope polished, rope rust, the strength of the joints will be greatly reduced, when in use, easily disconnected joints.
in addition, the conveyor belt, if not sealing glue, or glue joints in the wrong direction, the joints prone to cracking (surface plastic parts).
