The strength at the conveyor belt joint is lower than that of the normal belt body. Generally, when mechanically connected, the strength of the joint can only reach 40-50 percent of the strength of the belt body. When the quality of the cold glue method is better, the strength of the joint can reach 60-70 percent , and the strength of the hot glue joint can reach 80-90 percent ( The joint method is correct and there is no quality defect).
Because the strength of the joint is relatively low, if the bonding method is not correct, the strength of the joint will be even lower, such as cutting, scratching the next layer of cloth, excessive grinding, insufficient lap length, insufficient number of steps, glue joints The rubber used has poor performance or has failed self-sulfurization, the wire rope is over-polished, the wire rope is rusted, etc., the strength of the joint part will be greatly reduced, and the joint part is prone to disconnection during use.
In addition, if the conveyor belt does not use sealing glue, or the direction of the glue joint is wrong, the joint part is prone to cracking (surface glue part).
