1.国内现状轮胎钢帘线又称轮胎钢丝绳,它是用于汽车、飞机、拖拉机等子午线轮胎的骨架材料,占轮胎总重量的10～15％。它承受轮胎的负荷,经受行驶过程中周期性的应力和变形作用,是轮胎工业的重要原料之一。钢帘线与传统作骨架材料的纤维织物相比,优点是:①导热性能好(轮胎在高速运转时产生的热量容易散发);②具有高的强度,且不受温度的影响(在其它纤维织物毁坏的温度下,钢帘线却能维持原来抗拉强度的93％);③抗拉张力大,耐冲击性好。因此,用钢帘 1. Domestic Status Tires Steel cord, also known as tire cord, which is used in automobiles, aircraft, tractors and other radial tire skeleton material, accounting for 10-15% of the total weight of the tire. It withstands the tire load, withstand the cyclical stress and deformation during driving, is one of the important raw materials for the tire industry. The advantage of steel cord compared with the traditional fabric made of skeleton material is that: ① good thermal conductivity (the heat generated by the tire at high speed is easy to dissipate); ② high strength and independent of temperature (in other fibers Fabric destruction of the temperature, the steel cord can maintain the original tensile strength of 93%); ③ tensile tension, good impact resistance. Therefore, with steel curtain
