Boao Rubber
1 / 2
According to the different properties of the covering adhesive, it can be divided into cold resistant, acid resistant, alkali resistant, oil resistant, wear-resistant, etc.
According to different purposes, it can be divided into lifting belts, power belts, and conveyor belts.
According to the different structures, it can be divided into ordinary laminated type, impact resistant type with lateral reinforcement layer, and tear resistant type.
National Standard GB/T7984-2001
Nylon (NN) Conveyor Belt:
Cover layer: tensile strength not less than 15 MPa, tensile length at break not less than 350%, wear amount ≤ 200mm³
The average value of interlayer bonding strength in longitudinal specimens shall not be less than 4.5 N/mm between layers, and not less than 3.2 N/mm between covering adhesive and fabric layers.
The longitudinal elongation at break of the entire thickness shall not be less than 10%, and the longitudinal reference force elongation of the entire thickness shall not exceed 4%.
