航空轮胎硫化管路系统的升级改造

Upgrade of Curing Pipeline System of Aircraft Tire

在传统等压等温硫化工艺基础上,通过对现有内压管路系统和外压管路系统进行改造升级,研究航空轮胎的新型等压变温硫化工艺。结果表明,采用新型等压变温硫化工艺,管路工作正常,温度和压力稳定,成品轮胎内衬层部位过硫化程度明显降低,既能保证产品质量和性能,又能大幅节约能源,降低动力消耗成本。

The new curing process of aircraft tires under constant pressure and variable temperature was investigated by using a modified traditional curing process which was originally operated under both constant pressure and constant temperature.The modification of the equipment was mainly the upgrading of current internal and external pressure pipeline systems.With the new process,the pipeline worked normally,the temperature and pressure were stable,and the degree of over vulcanization of the inner liner of the finished tire was significantly reduced,which could not only ensure the product quality and performance,but also greatly save energy and reduce the power consumption cost.
