挤橡工艺参数对橡皮电线电缆产品质量的影响

Crowded rubber process parameters on rubber wire and cable products quality influence

电线电缆的挤橡是通过挤橡机的螺杆压缩,再由模具成型在导电线芯或成缆线芯上包一层整体的、紧密的、厚度均匀的绝缘或护套的工艺加工过程。绝缘层或护套层的质量除受橡皮配方、橡胶混炼质量、橡料塑性等因素的影响外,还受挤橡时的挤出温度、挤包速度、挤橡模具的质量和选配等一系列因素影响。

The crowded rubber wire and cable is through crowded rubber machine screw compressed, again by molds in conductive wire core or into the cable core packet layer of holistic and close, thickness of insulation or sheath craft processing process.Insulat- ing layer or sheath layer by the quality of rubber formulation, rubber except mixed refine plastic, rubber material quality of the in- fluence of factors outside, still be crowded the extrusion temperature, rubber squeeze packet speed, crowded rubber mold quality and matching, and a series of factors.
