How to select rubber conveyor belt-2

Choice of cover layer: The choice of cover layer includes cover material, surface shape and thickness. The main components of the cover layer are various rubbers and plastics. Under most climatic conditions, the rubber band can work normally under the condition that the inclination angle is not more than the flat angle. The angle of inclination of the flame-retardant conveyor belt is below 120 degrees. Although the main frame material is not as good as the rubber, it has good flame retardancy, unloading and cleaning properties, and The performance of rubber is also very different. For example, natural rubber and styrene-butadiene rubber have good energy absorption and abrasion resistance. Ethylene-propylene rubber is particularly heat-resistant. Butyl cyanide rubber has good oil resistance. Propylene-butyl rubber is heat-resistant and resistant. Oxidation chemistry, so the choice of type of cover material must be based on the type of commonly used materials, operating conditions and working environment;

In addition, the increase of the thickness of the cover layer is also beneficial to improve the impact resistance and wear resistance of the rubber conveyor belt. In particular, the cotton canvas core has been replaced by the core of the synthetic fiber fabric, the performance of the core has been greatly improved, and the thickness is relatively thin. In order to improve the overall performance of the belt, it is necessary to increase the thickness of the cover layer to fully exert its advantages and improve the service life of the conveyor belt, but the excessive thickness of the lower cover layer will make the running resistance of the heavy-duty heat-resistant conveyor belt become larger. This point needs attention; the running resistance of the heat-resistant conveyor belt becomes large, which requires attention;
