The strength at the conveyor belt joint is lower than that of the normal belt body. Generally, when mechanically connected, the joint strength can only reach 40-50% of the strength of the belt body. When the quality of the cold bonding method is better, the joint strength can reach 60-70%, and the thermal bonding joint strength can reach 80-90%. (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 the knife, damaging the next layer of cloth during grinding, excessive grinding, insufficient lap length, insufficient number of steps, and bonding. The rubber used in the joint 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).

We are a rubber production base from design, production, sales to service. Our company produces various specifications of steel wire rope core (ST) resin high strength (EP) nylon strength (NN) acid and alkali resistance, heat resistance, oil resistance, cold resistance, ordinary, food, strong ultra-thin, flame retardant conveyor belt 12 million square meters . The products sell well in various provinces and cities in China and are exported to many countries and regions in the Middle East, Europe, South America, Southeast Asia, Africa, etc., and are widely used in mining, metallurgy, construction, electricity, transportation, and ports. We have passed the ISO9001: 2000 quality management system certification and are a famous trademark in Zhejiang Province. The company aims to base itself on the domestic market and look at the world, and in line with the tenet of "survive by quality, develop by science and technology, and seek cooperation by reputation", we provide every customer with the best quality service.
