随着世界汽车工业和道路交通网的高速发展,轮胎工业也在高速发展,促使子午线轮胎从第一代子午胎(普通断面,有内胎)向第二代子午胎(低断面,无内胎)发展,随着人们环保意识的不断增强,又推动了子午线轮胎向“绿色”子午胎发展,要求轮胎重量轻、滚动阻力低、油耗低,用完后的轮胎可以回收利用。而芳纶帘线具有低密度、低伸长变形、高
With the rapid development of the automobile industry and road network in the world, the tire industry is also developing at a rapid pace, prompting the development of radial tires from the first generation of radial tires (ordinary section with inner tube) to the second generation of radial tube (low section, tubeless) With the continuous improvement of people’s awareness of environmental protection, it has also promoted the development of radial tires to “green” radial tires, requiring tires with light weight, low rolling resistance and low fuel consumption, and can be recycled after use.
