摘要
钢帘线生产过程如果控制不当,会产生轮胎使用过程带束层帘线芯线(或芯股)冒出的缺陷,严重影响轮胎的安全使用。通过对钢帘线的生产工艺分析与试验,以及对芯线刺出的轮胎解剖分析认为,是钢帘线芯线丝径控制不当、股线低负荷伸长率不合理以及钢帘线捻制工艺不合理,致使钢帘线芯股冒出。以7×7×0.25+0.15HT钢帘线生产为例,采取严格控制芯线丝径,科学设定股线低负荷伸长率,同时合理控制管绞机捻制工艺等措施,有效避免了钢帘线芯股冒出,保证了轮胎在使用过程中的安全性能。
Defects of steel cord core with belt outshot occurred in tire use if it was controlled improperly in steel cord pro duction process, which affect safety use of tire seriously. The production process of steel cord is analyzed and tested, and tire of core wire outshot is anatomical analyzed, the reason of steel cord core outshot is incorrect steel cord core diameter control and irrational cord low load elongation and unreasonable steel cord laying process. To take 7 x 7 x 0.25 ＋ 0.15HT steel cord production as an example, measures are adopted such as control core diameter strictly, set strand low load elon gation scientifically, control tubular strander cabling process, steel cord core outshot can be avoided effectively, and the safety performance of tire during use is guaranteed.
