    • PURPOSE: A steel cord of a pneumatic radial tire is provided to keep technical advantage of the existing core-parallel 2+5 structure and to improve the durability of the tire by removing stress concentration on a core filament by two-dimensionally deforming the core filament. CONSTITUTION: A steel cord applied for a belt or a carcass comprising a pneumatic radial tire has a 2+5 structure composed of two core filaments arranged in parallel to each other and five sheath filaments for covering the core filaments. Two core filaments are deformed two-dimensionally. The diameter of the core filament is 0.15¯0.30 mm. The diameter of the sheath filament is 0.22¯0.40 mm. The diameter ratio(Dc/Ds) of the core filament and the sheath filament is 0.5
    • 目的:提供充气子午线轮胎的钢丝帘线,以保持现有的芯平行2 + 5结构的技术优势,并通过将芯丝二维变形来消除芯丝上的应力集中度来提高轮胎的耐久性 。 构成:用于包括充气子午线轮胎的皮带或胎体的钢丝帘线具有由彼此平行布置的两根芯丝组成的2 + 5结构和用于覆盖芯丝的五根护套长丝。 两根芯丝二维变形。 芯丝的直径为0.15〜0.30mm。 护套长丝的直径为0.22〜0.40mm。 芯丝和外皮长丝的直径比(Dc / Ds)为0.5≤Dc/ Ds <= 0.85。 护套长丝的扭曲长度(Ls)为10.0 <= Ls <= 20.0mm。

    • PURPOSE: A reinforcing steel cord for rubber products such as steel belted radial tires or conveyor belts having improved rubber penetration and ageing adhesive force to rubber material by improving the mechanism of a twisted core to minimize the continuous contact of the core and external wires and forming sufficient interspaces between the core and the external wires is provided, which is most preferably used as a reinforcing material for steel belted radial tires. CONSTITUTION: In the steel cord, the pitch of the twisted core is set to allow the core to be twisted 0.2 to 2 times within the pitch of the cord, thus preferably forming sufficient interspaces between the core and the external wires in addition to the interspaces between the external wires. Since the rubber material is completely filled in the steel cord due to such interspaces, the steel cord is remarkably improved in buckling fatigue resistance, rubber penetration, air permeability, rubber adhesive force, ageing adhesive force relative to rubber, protection of brass coated surfaces of wires, and workability during a process of producing rubber products.
    • 目的:一种用于橡胶制品的增强钢丝绳,例如钢带子午线轮胎或输送带,通过改进扭绞芯的机构,改善橡胶的渗透性和对橡胶材料的老化粘合力,使芯和外部电线的连续接触最小化并形成 提供了芯和外部线之间的足够的间隙,其最优选地用作钢带子午线轮胎的增强材料。 构成:在钢帘线中,扭绞芯的间距被设定为允许芯在帘线的间距内扭转0.2至2倍,因此除了间隙之外,优选地在芯和外部线之间形成足够的间隙 外部电线之间。 由于橡胶材料由于这种间隙而完全填充在钢帘线中,所以钢帘线在抗弯疲劳性,橡胶渗透性,透气性,橡胶粘合力,相对于橡胶的老化粘合力方面显着提高,黄铜涂层表面的保护 电线,以及在生产橡胶制品的过程中的可加工性。
