缺气保用半钢子午线轮胎胎里气泡问题的解决措施

Methods to Solve Bubble Problem in Run-flat Steel-belted Radial Tire

对缺气保用半钢子午线轮胎生产过程中产生的胎里气泡问题进行原因分析,并提出相应的解决措施。通过增加一段成型鼓支撑胶凹槽设计,增大内衬层和支撑胶粘性,增加支撑胶张力压合装置、导开浮动辊调节装置和支撑胶刺孔装置,有效解决了缺气保用半钢子午线轮胎的胎里气泡问题。

The causes of bubble problem in the run-flat steel-belted radial tire during the production were analyzed,and the corresponding methods were put forward.By adding a groove design for the supporting compound of the first-stage building drum,increasing the tackiness of inner liner compound and supporting compound,adding a tension pressing device,a leading-off floating roller adjusting device and apricking device for the supporting compound,the bubble problem in the run-flat steel-belted radial tire was effectively solved.
