随着消费者对轮胎安全性能关注度的提高,轮胎的安全性能已经成为每一个轮胎企业的科研发展方向。半钢子午线轮胎子口护胶打褶,因无法在外观检查及X光机检测中发现,缺陷轮胎很容易流入市场。打褶轮胎在使用10~12个月后,在胎侧下端位置可能出现周向裂口,造成漏气,甚至在高速运行情况下爆胎,对车上人员的安全造成威胁,存在极大安全隐患。本文通过对可能引起子口护胶形状打褶的原因,展开对比试验,进行研究。
As consumers pay more attention to tire safety performance, the safety of tire has become the research and development direction of every tire enterprise. Semi-steel radial tire spout gums pleated, due to the appearance of the inspection and X-ray detection can not be found, defective tires easily flow into the market.
