Technical indexes
Physical property of cover rubber under hot air accelerated aging test(test condition:50℃*96h)
Table 1
Item | Tensile Strength | Elongation at break | Abrasion | Hardness | Ozone deterioration | ||
| /Mpa | /% | /mm3 | /(°) | ||||
| ≥ | ≥ | ≤ | 10 | ||||
COVER | Physical property | Before aging | 14 | 400 | 250 | 60 | no cracks |
| After aging | 12 | 340 | - | 65 | - | ||
COVER | Acid and alkali resistance | Class | Soak liquid | Density | Soak conditions | Change rate before and after soak | |
| °C x h | Swelling rate | Change rate of tensile strength | |||||
| A1 | HCI | 18% | 50°C x 96h | ≤+10% | ≤-10% | ||
| A2 | H2SO4 | 50% | 50°C x 96h | ≤+10% | ≤-10% | ||
| A3 | NaOH | 48% | 50°C x 96h | ≤+10% | ≤-10% | ||
Note: When the thickness of the cover rubber is 0.8mm-1.6m, the sample thickness can be the maximum cut length, the tensile strength
and the elongation at break are allowed to be 15% lower than those in the table.
