We all know that belt conveyors have the problem of conveyor belt bonding. When replacing conveyor belts, many users use the method of on-site bonding. The cold bonding method is the main method, and its bonding method and bonding process are very important. If there is no good process and method, the service life of the bonded belt joints is very short, and some joints even break after only 3-5 months.
Disadvantages of the old process bonding conveyor belt
Usually the method of bonding the conveyor belt is to use the miter or direct method, and the conveyor belt is first stripped into three or four layers. In order to increase the tensile strength of the joint, put one or two layers of cloth on the surface adhesive layer, which will improve the tensile strength of the bonded conveyor belt joint.
But at the same time, it also leads to some problems. Because the surface adhesive layer has a cloth layer, there is often a phenomenon of lap opening and warping at the seam. Especially the joints of the working face are more serious. As a result, water and sand enter at the beginning, which greatly shortens the service life of the conveyor belt joint.
A new process for conveyor belt bonding.
Add a 50mm wide pure surface adhesive layer without cloth to the upper and lower adhesive parts of the interface of the conveyor belt. The 50mm wide pure surface adhesive layer is much more elastic than the cloth-containing surface adhesive layer. And soft. Therefore, this kind of joint will not produce seam opening and edge warping. It can also prolong the service life of the conveyor belt joint.
