摘　　要：分析轮胎胎面挤出质量波动的原因,并提出相应解决措施。原材料性能波动、终炼胶性能不稳定、挤出胎面尺寸波动、终炼胶停放时间差异、操作差异性、挤出胎面质量监控方法不科学和工艺与工装不匹配是造成胎面质量波动的主要原因,通过采取改进原材料采购形式、严格控制终炼胶性能、提高挤出部件尺寸控制精度、控制终炼胶停放时间、消除操作差异性、采用挤出部件质量自动筛选系统以及确保工艺与工装匹配等措施,稳定了胎面质量,使成品轮胎合格率大幅提高。The reasons for the fluctuation of tire tread extrusion quality were analyzed and the corresponding solutions were put forward.The main reasons for the fluctuation of tread quality were the fluctuation of raw material properties,unstable final stock properties,fluctuation of extrusion tread size,difference in the parking time of the final stock,operational differences,unscientific quality control method of the extruded tread and mismatch between the process and the equipment.By adopting measures such as improving the control of the procurement of raw materials,strictly controlling final stock properties,improving the dimensional control accuracy of the extruded parts,controlling the parking time of the final stock,eliminating the difference of operation,adopting an automatic screening system for the quality of the extruded parts,and ensuring the matching of the process and the equipment,the tread quality was stabilized and the qualified rate of the finished tire was greatly improved.
