研究以3+8×0.21ST钢丝帘线替代3+9×0.22W钢丝帘线在11R22.5 16PR全钢载重子午线轮胎中的应用。结果表明,采用3+8×0.21ST代替3+9×0.22W钢丝帘线作为轮胎的胎体帘线,不仅可保证轮胎的安全性能和耐久性能,还减小了轮胎质量,并降低了原材料成本。
The application of 3 + 8 × 0.21ST steel cord to replace 3 + 9 × 0.22W steel cord in 11R22.5 16PR all-steel radial truck tire was studied. The results show that using 3 + 8 × 0.21ST instead of 3 + 9 × 0.22W steel cord as the carcass cord of the tire can not only ensure the safety performance and durability of the tire, but also reduce the tire quality and reduce the cost of raw materials cost.
