1. Selecting nylon canvas or EP canvas as the carcass.
2. The rubber cover made from acid- alkaline resistant materials.
3. Has good elasticity,great anti-chemical corrosiveness and good physical properties.
4. Suitable for such acid-alkali working conditions.
5. Chemical resistant conveyor belt, (i.e. acid/alkali resistant conveyor belt) is suitable for such acid-alkali working conditions as paper mill, phosphate fertilizer, sea salt industries, cement Industries.
Acid-alkali resistant properties of rubber cover:
| Class | Soak liquid | Concentration | Soak conditions(℃×h) | Change rate of properties before and after soaking | |
| Volume expansion rate | Change rate of tensile strength | ||||
| A1 | Hydrochloric acid (HCl) | 18% | 50℃×96h | ≤+10% | ≥-10% |
| A2 | Sulfuric acid(H2SO4) | 50% | 50℃×96h | ≤+10% | ≥-10% |
| A3 | Sodium hydroxide(NaOH) | 48% | 50℃×96h | ≤+10% | ≥-10% |
