This kind of product is suitable for the acid contact condition, eg phosphoric fertilizer, abstracts salt from sea water The covering layer rubber is the mixture of rubber and plastic and filled with acid resistantinert materials, which is much better than LDR acid resistant conveyer belt. The framework material is EP canvas, is more reliable and the cotton canvas core belt. Generally it is made into dng shaped. | | The performance of resistant conveyer belt is as the following table: | Type | Break the intensity /Mpa≥ | Break extension rate /%≥ | Wearing and tearing /mm3≤ | Hardness/(o)+10 -5 | Performance before wearing out | 14.0 | 400 | 250 | 60 | Performance after wearing out | 12.0 | 340 | - | 65 | | The acid resistant of the acid and alkali resistant conveyer belt coveing layer is as the following table: | Classification | Immersion solution | Density | Soaking condition TemperatureXtime | Soak the rate of change of front and back performance | Volume expansion rate | Change rate of strength | A1 | HCL | 18% | 50°C×96h | +10% Following | -10% within | A2 | H2SO4 | 50% | 50°C×96h | +10% Following | -10% within | A3 | NaOH | 48% | 50°C×96h | +10% Following | -10% within |
