Strength standard for ordinary conveyor belts
General conveyor belt cover: tensile strength not less than 15MPa. Tensile elongation not less than 350%, the wear is equal to or less than 200mm3; interlayer bonding strength longitudinal sample average value between the cloth layers is not less than 3.2N/mm; cover the glue and cloth layer is not less than 2.1N/mm; full thickness longitudinal elongation at break is not small in 10%; full thickness of vertical reference force elongation of not greater than 1.5%.
Nylon (NN), polyester (EP) conveyor belt: overlay: tensile strength not less than 15MPa, tensile elongation not less than 350%, the wear is equal to or less than 200mm3, interlayer adhesion strength longitudinal sample average value between the cloth layers is not less than 4.5N/mm, plastic cover and the cloth layer not less than 3.2N/mm. Full thickness longitudinal to elongation of not less than 10%, the total thickness longitudinal reference force elongation is less than 4%, the plastic cover with rubber blend, skeleton GB level tensile strength coefficient can be spliced into a ring.
