Why is the EP conveyor belt splicing section easy to crack and disconnect?

The strength at the splicing section of the EP conveyor belt is lower than that of the normal belt body. When mechanically connected, the strength of the splicing section can only reach 40-50% of the strength of the belt. When the quality of the cold splicing method is better, the strength of the splicing section can reach 60-70%, and the strength of the vulcanization splicing can reach 80-90%. (The connection method is correct and no quality defects). Because the strength of the splicing section is relatively low, if the splicing method is not correct, the strength of the splicing section will be lower, such as the operation of the knife, the next layer of cloth is injured during grinding, excessive grinding, insufficient overlap length, insufficient number of steps, bonding The skim rubber used in the splicing section has poor performance or has lost its self-sulfur, excessive grinding of the wire rope, rust of the wire rope, etc., the strength of the splicing section will be greatly reduced, and the phenomenon of disconnection of the splicing section is easy to occur during use.

In addition, if the EP conveyor belt does not use sealing glue or the direction of the rubber splicing section is wrong, the splicing section is prone to cracking (face adhesive part), and the same phenomenon will occur.
