| 中文摘要: |
| 分析影响轮胎胎圈敷贴质量的因素，并提出相应解决措施。三角胶用终炼胶门尼粘度和硬度偏高、三角胶根部几何形状设计和三角胶结构设计缺陷、三角胶生产参数异常、部件尺寸不合格、设备精度不达标以及物料存放环境温度和湿度不合适等均会造成胎圈敷贴质量不合格。通过采取严格控制三角胶用胶料性能、优化三角胶口型设计、制定三角胶设计参数对照表、固定三角胶生产参数、确保部件尺寸合格和设备精度达标以及固定物料存放环境条件等措施，保证了胎圈质量的合格率。 |
| 英文摘要: |
| The factors affecting the tire bead sticking quality were analyzed，and the corresponding solutions were put forward.The high Mooney viscosity and hardness of the apex compound，the defects in the root geometric design and structure design of the apex，the abnormal production parameters of apex，the unqualified component size，the unqualified equipment accuracy，and the inappropriate ambient temperature and humidity for material storage would all lead to the unqualified bead sticking quality.The qualified rate of bead quality was ensured by strictly controlling the performance of the apex compound，optimizing the die design of apex，formulating the comparison table of apex design parameters，fixing the production parameters of apex，ensuring that the component size qualified and the equipment accuracy meeting the standard，and fixing the material storage environmental conditions. |
