Plastic and rubber band compared with the core layer similar to the use of PVC as a coating layer instead of the rubber, which is characterized by low cost and good quality with the belt connection method is to open the respective two tape core, corresponding knot, and then paste the PVC film on both surfaces, hot forming, the strength up to the original 75% to 80%.
Common conveyor belt conveyor belt core types by the following three main points are: (1) fabric conveyor belt. Fabric conveyor belt in the gasket material is used more cotton fabric liner, namely cotton canvas and into the fiber fabric liner. Such as rayon, nylon, polyamide, polyester and the like. China's production of the entire core liner bags, because based on domestic raw materials with wear, corrosion, acid, oil, etc., have also been widely used. In addition, there is the type of belt canvas bag, plastic bag, anti-static plastic bags, rubber bands and metal. Conveyor belt core depends mainly on tape under tension, the rubber layer is used to prevent the material impact, friction and moisture damage with the core, so the glue layer thickness than the next. Shown in Figure 2-4.
(2) steel conveyor belt (wire rope, steel fibers or steel). At the mine or the port has adopted long-range, high-capacity belt conveyor. Such use of steel cord conveyor or steel cord conveyor belts. Just rope conveyor belt is twisted into a high-quality steel wire rope arranged side by side and wrapped with rubber and canvas as the band conveyor belt. Steel cord conveyor belt is used as a thin steel core and outsourcing rubber conveyor belt. Such belt elongation, high strength, used in transport length big occasions.
(3) pattern tape. Both the bearing surface of the tape is designed to irregularity of the pattern, thereby increasing the friction between the belt and the material to improve the transmission angle. Enhance the same height, the length of the belt is greatly reduced, and thus connection province area.
