Stripping transport belts before vulcanization is the most important stage of repair
The conveyor belt is the working body of the continuous movement of transport, it is a flexible strip that is closed in a circle (ring). When the edges are connected, this is extremely responsible, since this place is the most vulnerable to the canvas. In addition, the seam must be uniform and smooth – this affects the wear and durability of rollers and drums. There are three main ways to connect belts on conveyors – this is a mechanical closure, as well as vulcanization (hot and cold are applied to this method). When mechanical fixation occurs, the installation of connecting elements destroys the structure of the surface, which can adversely affect its life, thus vulcanization is considered the best choice for banding.
Repair of a conveyor belt by vulcanization is carried out in hot and cold mode. First, the use of high temperatures is pressure welding with a vulcanizer. Secondly, gluing with the help of special self-vulcanizers. Both technologies are associated with overlapping edges, which means the separation of the glued parts with a step (oblique). Conveyor belts are cleaned before the vulcanization stage, because this is one of the important stages of preparation, which determines how well the joints will be made, their durability and strength.
Our company TOV NVP “Ukrenergopostach”, along with repairs, is engaged in sale of consumables for repair and maintenance of conveyor belts. As an additional service, we are ready to offer gluing of rubber-fabric, rubber-cord and polymer sheets, vulcanization technologies (cold and hot), or mechanical closure will also be used. Our product range includes special devices and tools that allow you to optimize the processes of connecting conveyor belts in any way. If you have additional questions, you can contact and contact our consultants by calling +38 (067) 484-49-31.
Seam cutting is a complex process that requires special attention of the performer. The length of the seams (400 mm – 2 m), as well as parameters such as the angle of the seam, the number and length of the steps are calculated depending on the operational characteristics of the fabric, strength and number of fabric layers. In the process, when the layers are sheared, it is important that the textile frame is not damaged, as in this case the strength of the product will be impaired and the service life of the product will be reduced.
Before vulcanization, the conveyor belts must be polished with cut steps, rubber residues, dust residues from the connected surfaces must be removed through brushes or compressed air, the surfaces must be degreased with special solvents, remember that gasoline should never be used for such purposes! This process should be taken extremely responsibly, especially if cold vulcanization is used. Foreign ingredients should not get into the glue, this can weaken the properties of the glue, which in turn will adversely affect the uniformity and reliability of the joint.
