| 中文摘要: |
| 分析半钢子午线轮胎胎里径向裂口的原因并提出相应的解决措施。帘布电子辐照预硫化辐照剂量不足、帘线伸张率大、部件接头不良、肩部材料过渡不良、喷涂剂或隔离剂使用不当、硫化胶囊选取不合适、硫化参数设定不合理、胶料门尼粘度低等均会导致轮胎胎里径向裂口。通过合理选取工艺参数、加强工艺管理、严格执行技术标准、优化结构设计等措施，可有效避免轮胎胎里径向裂口，从而降低轮胎废品率。 |
| 英文摘要: |
| The causes of radial crack in inner surface of steel-belted radial tire were analyzed，and corresponding solutions were proposed.Insufficient irradiation dose，high cord elongation，poor component joint，poor shoulder material transition，improper use of spraying agent or isolating agent，improper selection of vulcanization capsule，unreasonable setting of vulcanization parameters and low Mooney viscosity of compound would lead to the radial crack in inner surface of tire.Measures such as reasonable selection of process parameters，strengthening of process management，strict implementation of technical standards，optimization of structure design could effectively avoid the radial crack in inner surface and reduce the reject rate. |
