The corrugated sidewall conveyor belt with large inclination angle is the main component of the belt conveyor with large inclination angle. As a flexible construction of conveyor, corrugated sidewall conveyor belt with large inclination angle plays a role of traction and loading material in conveyor equipment.

The corrugated sidewall conveyor belt is composed of diaphragm, baffle and baseband. The base belt of the conveyor belt is glued with flexible wavy baffles on both sides, and then the upper diaphragm is pressed between the two sides of the baffles. The diaphragm requires a certain degree of elasticity and strength. In this way, the baseband, partition, side barrier will form a

container, which can convey goods at large inclination or vertical angle. It is widely used in coal, power, building materials, grain and other industries. Due to the influence of conveying environment, corrugated conveyor belts with large inclination may be damaged by partitions. Therefore, it is necessary to repair the damaged conveyor belts in time so as to improve conveying efficiency.

Repair of corrugated conveyor belt

The conveyor belt needs to be modified by surface grafting before repairing, so that the repairing

bonding interface can be kept clean and tidy. Then methyl methacrylate or natural rubber graft copolymer solution is evenly coated on the surface and dried by hot air.

The repairing of rubber conveyor belt needs three materials as broken isocyanate, polyurethane prepolymer and amino-terminated composite mineral refiner. The three materials are mixed uniformly at 1:1:1, then poured in, and the performance test is carried out after 12 hours' standing. Then the two-component polyurethane PR-B tape repairing adhesives sold on the market were compared. It was found that the two-component polyurethane repairing adhesive can not only shorten the repairing time, but also save resources and maintenance costs. Underground repairing can reduce cost, operate simply and easily, and pollute the environment less.
