Cotton Conveyor Belt
1. Applications
Cotton conveyor belt is suitable for transportation of short-distance, medium quantity.
2. Physical properties of rubber cover (before aging)
Grade | Tensile Strength/Mpa ≥ | Breaking Elongation/% ≥ | Abrasion Loss/mm3 ≤ |
H | 24 | 450 | 120 |
D | 18 | 400 | 100 |
L | 15 | 350 | 200 |
Note: 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. 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) ≥ | 3.2 | 2.1 | 2.7 |
All samples min peak value/ (N/mm) ≥ | 2.7 | 1.6 | 2.2 |
Note: All samples max peak value is not more than 20N/mm. | |||
