| 中文摘要: |
| 介绍全钢子午线轮胎外观质量缺陷产生原因及解决措施。通过合理设计和严格控制轮胎各部件的尺寸和质量、改进模具结构和定期清洗模具、保证轮胎各部件良好粘合、确定合理的硫化及定型工艺参数、及时修理或更换设备损坏配件等可以有效解决全钢子午线轮胎胎趾圆角、气泡脱层、胎侧接头开裂、胎圈变形、胎里露线、胎侧缺胶等外观质量缺陷。 |
| 英文摘要: |
| The causes of appearance defects of all steel radial tire were analyzed， including bead toe defect，bubble and layer separation， sidewall joint crack， bead deformation， exposed cord， sidewall indentation， and so on. The corrective action was proposed to minimize those defects. The parts were well designed and the quality was strictly controlled. The mold structure was modified and the molds were cleaned regularly. Good adhesion
of different parts was ensured. Suitable shaping and curing processes and parameters were selected. Damaged accessories and equipments were repaired or replaced promptly. |
