Acid- and Alkali-Resistant Conveyor Belt
Product Description
When the cover胶 thickness ranges from 0.8 mm to 1.6 mm, the sample can achieve the maximum cutting length, while the tensile strength and elongation at break are permitted to be 15% lower than the values listed in the table.
Suitable for transporting corrosive materials such as acidic or alkaline substances in industrial facilities like chemical plants, fertilizer plants, and paper mills.
Features
1. Cotton canvas, nylon canvas, or polyester canvas is selected as the core material, offering excellent elasticity, superior groove-forming performance, and minimal elongation during use.
2. The covering rubber is manufactured from acid- and alkali-resistant materials, offering excellent chemical corrosion resistance as well as superior physical properties.
Technical indicators
Accelerated aging test of rubber physical properties under thermal conditions (test conditions: 50°C × 6 hours).
| Level | Soaking solution | Concentration | Soaking conditions: Temperature × Time | Performance Change Rate Before and After Immersion | |
| Volume expansion rate | Rate of intensity change | ||||
| A1 | Hydrochloric acid (HCl) | 18% | 50°C × 96 hours | Less than +10% | Within 10% |
| A2 | Sulfuric acid (H₂SO₄) 2S04) | 50% | 50°C × 96 hours | Less than +10% | Within 10% |
| A3 | Sodium hypochlorite (NaOH) | 48% | 50°C × 96 hours | Less than +10% | Within 10% |
| Project | Fracture strength | Elongation at break | Wear and tear | Hardness |
| Performance before aging | ≥14.0 | ≥400 | ≤250 | 60 + 10 / -5 |
| Performance after aging | ≥12.0 | ≥350 | - | 65 + 10 / -5 |
Note:
When the cover胶 thickness ranges from 0.8 mm to 1.6 mm, the sample can achieve the maximum cutting length, with tensile strength and elongation at break allowed to be 15% lower than the values listed in the table.
