Conveyor belts are inevitable to be damaged during use, and there are many forms of damage, such as: edge delamination, ulceration, defect and cracking; long-distance longitudinal tearing, deep scratches, holes, large-area wear, and covering rubber Bulging or peeling, internal defects of joints, etc. Among them, the longitudinal tear is the most urgent, the edge damage is the most common, the internal defects of the joint are inevitable, and the service life after repair is the most concerned.
The commonly used repair methods for conveyor belts are mainly the following three
1. Hot repair method: usually use special repairer, vulcanizer and hot vulcanizing material suitable for conveyor belt to repair the damaged part of the conveyor belt with equal strength “no trace”. This kind of repair can completely eliminate the damage of the conveyor belt and restore it to its original state. It is suitable for more important, long-distance, high-speed, and large-volume transportation systems. Of course, special equipment and professionals are required to complete this type of maintenance. It is the most reliable and ideal method for conveyor belt maintenance.
2. Cold repair method: It is usually necessary to use special cold adhesive, repair film and special tools for the conveyor belt to fill the damaged parts of the conveyor belt to achieve the purpose of continuous operation. Obviously, this filling repair is a stopgap measure. Therefore, its main purpose is: cold repair in time when the conveyor belt is damaged, which can prevent the damaged part of the conveyor belt from expanding and extending, so as to effectively protect the core of the conveyor belt from damage, so as to wait and obtain The time and opportunity required for maintenance.
3. Mechanical repair methods: usually use clips, nails, connecting plates and screws or metal cords and special appliances made of metal materials to fix or connect the damaged parts of the conveyor belt to achieve the purpose of maintaining operation. Even in many times and occasions today, this seemingly simple, rough, and even ugly processing method can play an emergency function and get twice the result with half the effort.
To sum up: the most ideal and perfect repair of the conveyor belt must be carried out in strict accordance with the principle of “equal strength and same life”, that is, the hot repair process and technology can be used. The real purpose of the application of other repair techniques is to obtain the right time and opportunity for repair. Therefore, cold repair and mechanical repair must not be used as the ultimate treatment for damage to the conveyor belt. It is only convenient and simple, and the pursuit of low cost and short time, the result is likely to be endless troubles. We hope that every conveyor belt system management and maintenance staff must have a clear understanding and thorough understanding of the basic concepts of conveyor belt repair, and successfully and smoothly complete the glue connection and repair work of the conveyor belt.
