        National standard of nylon conveyor belt GB / t7984-2001

        Application: suitable for medium and long distance, high load and high speed.

        Features: 1. Good elasticity, impact resistance and wear resistance.

        2. Good flexibility, easy to groove.

        3. No mould erosion occurred.

        4. In line with the national standard gb7984-95

        Varieties: according to the function of cover adhesive, it can be divided into general type, heat-resistant type, fire-resistant type, cold-resistant type, acid and alkali resistant type and oil-resistant type.

        (1) Core materials: nn100, nn150, nn200, nn300, nn400

        (2) Width: 100 mm-1800mm

        (3) Cloth layer: 2-8 layers

        (4) Masking glue: working face: 1.5-8mm non working face: 0mm-4.5mm

        1. Physical and mechanical functions of cover adhesive:

        ·2. Bonding strength between layers:

        The average value of longitudinal samples shall not be less than 4.503.23.50, and the average value of transverse samples shall not be less than 4.503.23.50, and the maximum peak value of all samples shall not be greater than 202020, and the minimum peak value of all samples shall not be less than 3.92.402.9
