Joint technology for various conveyor belts

All conveyor belts must be connected into a ring to be used in practice, so the joint of the conveyor belt is a very critical preparation link. The quality of the joint directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly.

Surface treatment of glued materials

1) The influence of surface characteristics: 1. Cleanliness: A layer of low cohesive strength and low surface energy pollution layer and oxide film are adsorbed on the metal surface, which will reduce the bonding strength. Generally, when the metal surface is clean, the contact is small or even zero. After the material treatment, the contact changes with time, and it is easy to be polluted by the ambient atmosphere in the air, the contact angle increases, and the contact angle tends to be stable after about 5H. Contact angle and bonding strength before and after surface treatment 2. Roughness: The surface of the adhered material is polished with gauze or sandblasted, and the bonding strength can be improved by properly roughening the surface. The roughening process removes the pre-existing surface layer. Form a new surface

Precautions for repairing bonding and joint of conveyor belt in summer

In summer, when the conveyor belt joint is bonded, there will be non-stick and falling off after bonding. This is due to the humid weather in summer, especially after rain, the air humidity is high, and a layer of white fog will appear after the glue is applied. This is because the solvent in the adhesive takes away a large amount of heat from the surface of the glue during the volatilization process, causing water vapor in the air to condense on the surface and form white fog. The aqueous interface formed on the surface is incompatible with the oily interface formed by the adhesive, and the chemical effect formed between the two surfaces is very small, resulting in a significant reduction in the bonding strength of the adhesive. In case of this kind of problem, the solution we take is to remove the water on the surface by baking.
