Conveyor belt strength standard

- Dec 25, 2019-

Ordinary conveyor belts comply with GB7984-2001 standards.

Ordinary conveyor belt: cover layer: tensile strength is not less than 15Mpa, elongation at break is not less than 350%, abrasion amount is less than or equal to 200mm3; average interlayer adhesion strength is not less than 3.2N / mm between average layers; The distance from the cloth layer is not less than 2.1N / mm; the longitudinal elongation at full thickness is not less than 10%; the longitudinal reference force elongation at full thickness is not more than 1.5%.

Nylon (NN), polyester (EP) conveyor belt cover, tensile strength is not less than 15Mpa, elongation at break is not less than 350%, the average interlayer adhesive strength of longitudinal samples is not less than 4.5N / mm, covering rubber and cloth layer is not less than 3.2N / mm, full-length longitudinal breaking elongation is not less than 10%, full-thickness longitudinal reference force elongation is not more than 4%, covering rubber adopts rubber and plastic blending, skeleton The national standard level tensile strength coefficient can be overlapped into a ring.
