TBR轮胎胎体帘线稀并线原因分析与对策

Cause analysis and countermeasures of TBR tire carcass cord defects

分析TBR轮胎胎体帘布稀并线异常的产生原因,并提出相应解决方案。胶料流动性、工艺工装磨损、帘布渗胶质量、压延张力波动、胶部件接头缺陷、帘布局部拉伸等因素均会造成胎体帘线间距排列异常,通过优化混炼工艺、工艺工装精细管理、提升帘布渗胶质量、稳定钢丝压延张力、严控压延机积胶均一性与部件接头质量等措施,可有效解决胎体稀并线异常问题。

This article analyzes the causes of abnormal arrangement of TBR tire carcass ply and proposes corresponding solutions.Factors such as flowability of rubber material,wear of process fixtures,quality of fabric leakage,fluctuation of rolling tension,defects in component joints,and local stretching of fabric can all cause abnormal arrangement of tire body cord spacing.By optimizing the mixing process,finely managing the process tooling,improving the quality of fabric leakage,stabilizing the tension of steel wire rolling,and strictly controlling the uniformity of rubber material and component joint quality of the rolling machine,the problem of abnormal tire body and cord can be effectively solved.
