Steel Cord Construction Trends and the Developments in Bekaert钢帘线结构市场趋势及贝卡尔特的新产品开发 Contents 内容 Why Steel Cord Reinforced Radial Tires ? 为何选用钢帘线增强子午胎？ Steel Cord Construction Trends and Bekaert Developments 钢帘线结构市场趋势及贝卡尔特的新品开发 - Belts of Passenger Tires 乘用胎带束层 - Belts of Light / Small truck Tires 轻型/小型卡车胎带束层 - Belts of Medium/Heavy Truck Tires 中型/重型卡车胎带束层 - Carcasses of Truck Tires 卡车胎胎体 Why Radials ? 为何用子午胎？Endurance 耐久性 Radial tires run much cooler under all conditions (high speeds , high loads) and show higher durability compared to bias tires. 子午胎在所有的条件下（高速，重载）服役温度更低，因而较斜胶胎具有更好的耐久性 Why Radials ? 为何用子午胎？ Fuel Economy 燃油经济性 Radial tires and especially steel reinforced radials have lower Rolling Resistance leading to better fuel economy.Lower aspect ratio helps further. 子午胎尤其是钢帘线增强的子午胎因其滚动阻力较小而具有较佳的燃油经济性。小的高宽比对此有进一步的贡献。 Why Radials ? 为何用子午胎？ Value for the Money 花钱值不值 Why Radials ? 为何用子午胎？ Lower tire cost 轮胎成本更低 Why Radials? 为何用子午胎？ Retreadibility 可翻性 Radial Truck and bus tires get ,in the average, more than one retreads in USA. As a result , 55-60% of all tires are retreaded ones. 在美国，子午卡车胎及公共汽车胎平均翻修一次以上。因而在所有正在使用的轮胎中大约有55-60%被翻修一次。 Steel Cord Construction Trends 钢帘线结构趋势Belts of Passenger Tires 乘用胎带束层 Nx1 type cords allowing rubber penetration gained popularity in recent years over m+n types 近年来渗胶良好的 NX1型帘线较M+N型更为普及 HT types became almost an industry standard. 高强度几乎成为行业标准 Bekaert Developments 贝卡尔特新品开发 Belt Constructions- Passenger Tires 乘用胎带束层 nx1 Type Betru Cords: NX1 型贝特鲁帘线 It improves rubber penetration without excessive increase of diameter and cord elongation at low loads(LLE). 较传统帘线它改善了渗胶性能而并未很大程度地增大帘线直径及低载荷延伸 Insulation compound requirement goes down and ply gages are low. Cord processability in tire plants also improves. 带束层胶料的用量降低因而帘布更薄。帘线在轮胎厂的工艺性能亦得到了改善 Strength and Fatigue Level losses are negligible. So , Betru preforming can be used both for belt and carcass reinforcement. 帘线的强度及疲劳性能的损失可以忽略不计
