钢丝绳绳芯生产厂家的技术壁垒
Technical barriers for steel wire rope core manufacturers
1. 原料选择与预处理
1. Raw material selection and pretreatment
绳芯需从源头把控：
The rope core needs to be controlled from the source:
麻纤维：选用剑麻与黄麻的混合纤维，兼顾强度与柔韧性；
Hemp fiber: a mixed fiber of sisal and jute is selected to balance strength and flexibility;
PP纤维：采用高结晶度聚丙烯原料，抗蠕变性能提升40%；
PP fiber: made of high crystallinity polypropylene raw material, with a 40% increase in creep resistance;
钢芯：采用70#高碳钢线材，经多次冷拔与热处理，确保弹性极限。
Steel core: Made of 70 # high carbon steel wire, which has undergone multiple cold drawing and heat treatments to ensure its elastic limit.
2. 生产设备与工艺精度
2. Production equipment and process accuracy
实现：纤维张力控制：误差≤±0.5N，避免绳芯密度不均；
Implementation: Fiber tension control: Error ≤ ± 0.5N, avoiding uneven rope core density;
涂层均匀性：采用真空浸渍技术，润滑脂渗透深度达纤维直径的80%；
Coating uniformity: Using vacuum impregnation technology, the penetration depth of lubricating grease reaches 80% of the fiber diameter;
尺寸稳定性：通过恒温恒湿车间生产，确保绳芯直径公差≤±0.1mm。
Dimensional stability: Produced in a constant temperature and humidity workshop, ensuring a rope core diameter tolerance of ≤± 0.1mm.
