乘用车/轻型载重车子午线轮胎氮气硫化工艺

介绍乘用车/轻型载重车子午线轮胎氮气硫化工艺条件及工序。采取严格控制定型压力、增加胎侧板排气孔、及时更换老化胶囊、采用双工位后充气装置和加强设备管理等措施,解决氮气硫化轮胎出现的缺胶、重皮、胎里打褶和胀肚等外观缺陷。轮胎的氮气硫化工艺能耗低、硫化时间短、效率高,成品轮胎的外观合格率高,高速性能、耐久性能、动平衡性能和均匀性能好。

Nitrogen Vulcanization Process for Passenger Car/Light Truck Radial Tire

The nitrogen vulcanization process for passenger car radial tire and light truck radial tire was introduced. With strict control on the pressure, addition of extra side vent, timely replacement of capsule,application of duplex inflation devices and strengthening equipment management, the appearance defects of tire such as lack of rubber, repeat skin, corrugated inner surface or tire bulge could be reduced. The nitrogen vulcanization process had advantages in low energy consumption, short curing time and high efficiency.The pass rate of appearance quality of the finished tire was quite high, and the high-speed performance,endurance performance, dynamic unbalance performance and tire uniformity of the finished tire were excellent.
