Quality standard for rubber conveyor belts


1. The ordinary conveyor belt (including high-strength nylon conveyor belt) products implement the GB7984-2001 standard.
(1) Ordinary conveyor belt:
Cover layer: Tensile strength is not less than 15Mpa, elongation at break is not less than 350%, wear loss is ≤200mm3, interlayer adhesion strength is between not less than 3.2N/mm between longitudinal layers of the longitudinal sample, between the cover rubber and the cloth layer Not less than 2.1 N/mm, full thickness longitudinal elongation at break is not less than 10%, full thickness longitudinal reference force elongation is not more than 1.5%
(2) Nylon (NN), polyester (EP) conveyor belt:
Cover layer: tensile strength is not less than 15Mpa, elongation at break is not less than 350%, and wear is ≤200mm3
Interlayer adhesion strength The average value of the longitudinal sample is not less than 4.5N/mm between the layers, and the gap between the cover rubber and the cloth layer is not less than 3.2 N/mm.
Full thickness longitudinal elongation at break is not less than 10%, full thickness longitudinal reference force elongation is not more than 4%


2. Three-resistant conveyor belt (heat-resistant conveyor belt, acid-resistant conveyor belt, alkali-resistant conveyor belt) The product implements the HG2297-92 standard.


3. Flame-retardant conveyor belt The product implements the MT147-95 standard.
