探讨全钢子午线轮胎拉链爆原因及改进措施。全钢子午线轮胎发生拉链爆的3个主要原因是:过载引起钢丝帘线延伸断裂,钢丝帘线磨损导致其过载延伸断裂,钢丝帘线屈挠疲劳断裂。通过采用高强度钢丝帘线(提高胎体安全倍数)、控制压延锭子房湿度和温度、保证钢丝帘线压延张力均匀等措施,可以有效减少全钢子午线轮胎拉链爆问题。
Discussion on the Causes and Improvement Measures of All Steel Radial Tire Zipper Explosion. All three main reasons for all-steel radial tire zipper detonation are: overload caused by the extension of the steel cord fracture, wear and tear of the steel cord leading to its overload and elongation of the fracture, the steel cord flexion fatigue fracture. By using high-strength steel cord (to improve the safety factor of the carcass), control the temperature and humidity of the rolling spindle room, and ensure uniform calendering tension of the steel cord, it can effectively reduce the zipper explosion problem of the all-steel radial tire.
