Conveyor belt structure:
The belt core of the ordinary conveyor belt is composed of one or more layers of fabric or the whole belt core fabric. The material of the belt core should be impregnated with rubber or plastic or calendered and glued. There should be a cover layer outside the belt core layer. If necessary, a glued mesh cloth or curtain cloth buffer layer can be added between the belt core layer and the cover layer or inside the cover layer. The thickness of the buffer layer is included in the thickness of the cover layer, not the core layer. thickness.
Covering layer of ordinary conveyor belt:
The tensile strength is not less than 15Mpa, the elongation at break is not less than 350%, and the abrasion is less than or equal to 200mm3; the average value of the interlayer adhesion strength of the longitudinal sample is not less than 3.2N/mm between the cloth layers; the cover rubber and the cloth layer are not less than 2.1 N/mm; Full thickness longitudinal elongation at break is not less than 10%; Full thickness longitudinal reference elongation is not greater than 1.5%.
Nylon (NN), polyester (EP) conveyor belt: Covering layer:
The tensile strength is not less than 15Mpa, the elongation at break is not less than 350%, the abrasion is less than or equal to 200mm3, the average value of the interlayer adhesion strength of the longitudinal sample is not less than 4.5N/mm between the cloth layers, and the gap between the covering rubber and the cloth is not less than 3.2 N/mm, the full thickness longitudinal elongation at break is not less than 10%, the full thickness longitudinal reference elongation is not greater than 4%, the cover rubber is blended with rubber and plastic, and the frame is national standard tensile strength coefficient, which can be overlapped into a ring .
