介绍2+4×0.17UT钢丝帘线的基本性能、结构特征和帘布性能,并与3×0.30OCHT钢丝帘线进行对比。与3×0.30OCHT钢丝帘线相比,2+4×0.17UT钢丝帘线的线密度较小,破断力/线密度和破断力/帘线直径比值较高,可减小压延胶片厚度,利于提高轮胎的承载能力和安全性能,其外层4根单丝采用3mm的预变形和内层2根单丝采用15mm预变形的组合具有最佳的渗胶性能,达到全渗胶,并可显著减小帘布质量,降低成本。
The basic performance, structural characteristics and fabric properties of 2 + 4 × 0.17UT steel cords are introduced and compared with 3 × 0.30OCHT steel cords. Compared with 3 × 0.30OCHT steel cord, 2 + 4 × 0.17UT steel cord linear density smaller, breaking force / linear density and breaking force / cord diameter ratio is higher, can reduce the thickness of calendered film, which will help Improve the carrying capacity and safety performance of the tire, the outer layer of 4 monofilaments using 3mm of pre-deformation and the inner layer of 2 monofilaments with 15mm pre-deformation combination of the best seepage properties to achieve full penetration gel, and can significantly Reduce the fabric quality, reduce costs.
