EP/nylon conveyor belt is suitable for transporting lump, granular, powdery materials of normal temperature, non-corrosion in general conditions. It is widely used in metallurgy, construction materials, wharf, mining industries.
2. Physical Properties of Rubber Cover (before aging)
|Grade||Tensile Strength/Mpa ≥||Breaking Elongation/% ≥||Abrasion Loss/mm3 ≤|
Grade H-used for transporting sharp, abrasive materials which can damage belts badly.
Grade D-used for transporting highly abrasive materials.
Grade L-used for transporting medium-abrasion materials.
After-aging properties of rubber cover(70℃, 7days):
Tensile strength and breaking elongation are both not lower than 75% of before-aging values.
3. Full-thickness Tensile Properties
a. Longitudinal tensile strength, not less than the below table. (N/mm)
|Nominal belt type||160||200||250||315||400||500||630|
b. Full thickness, longitudinal elongation at reference force, not more than 4%.
c. Ply adhesion:
|Item||Ply to ply||Rubber cover to ply|
|Rubber cover thickness ≤1.5mm||Rubber cover thickness >1.5mm|
|All samples average value/ (N/mm) ≥||4.5||3.2||3.5|
|All samples min peak value/ (N/mm) ≥||3.9||2.4||2.9|
|Note: All samples max peak value is not more than 20N/mm.|
d. Straightness not more than 25mm
