| 中文摘要: |
| 介绍国内外耐热橡胶输送带的标准、分类、质量及应用情况。国内外耐热输送带标准中产品的耐热分级有所不同，耐热温度达到150 ℃以上的输送带产品很少。耐热输送带覆盖胶主体材料主要采用丁苯橡胶（SBR）和三元乙丙橡胶（EPDM），骨架材料主要采用涤棉帆布、涤锦帆布和锦纶帆布。输送带材料、结构以及使用环境不同，输送带的使用寿命差别较大；输送物料温度超过175 ℃、骨架材料采用涤锦帆布的耐热输送带容易起泡和脱层；EPDM耐热输送带适用于输送温度低于300 ℃的物料；覆盖胶主体材料采用SBR、骨架材料采用涤棉帆布的耐热输送带适用于输送较大温度范围的物料。 |
| 英文摘要: |
| The standards，classification，quality and application of heat-resistant rubber conveyor belt at home and abroad were introduced. The classifications of the heat-resistant grade for the heat-resistant rubber conveyor belt in domestic and foreign belt standards were different. Few conveyor belts could reach the heat-resistant temperature requirements of exceeding 150 ℃ . Styrene butadiene rubber（SBR） and ethylene propylene diene rubber（EPDM） were the main rubbers used in the cover compound of heat- resistant conveyor belts. Polyester and cotton canvas，polyester and nylon canvas and nylon canvas were the main skeleton materials. Due to the difference in material，structure and working condition，the service life of the conveyer belts varied greatly. When the temperature of materials to be transported exceeding 175 ℃， the conveyor belts with the skeleton material of polyester and nylon canvas tended to blister and delaminate. EPDM heat-resistant conveyor belts were suitable for conveying materials below 300 ℃. The heat-resistant conveyor belts using SBR cover and polyester and cotton canvas skeleton materials was suitable for conveying materials in a wide temperature range. |
