摘　　要：分析热空气硫化硅橡胶电缆绝缘层和护套层起泡的原因及控制技术。以控制电缆内空气、水分和内外压力平衡为出发点,从硅橡胶性能、水分含量、混炼工艺、结构厚度、挤出模具、电缆结构设计以及温度方面着手,研究控制硅橡胶电缆产品起泡的技术要点和方法。通过多种控制技术的实施,有效解决了热空气硫化硅橡胶电缆绝缘层和护套层起泡的问题,提升了产品品质,降低了生产成本。The root causes of blistering on the insulating layer and the sheath layer of hot air cured silicone rubber cable were analyzed and control methods were proposed.The possible factors such as the properties of silicone rubber,moisture content,mixing process parameters,part thickness,extrusion die,cable structure design and temperature,were studied.Then the control methods were proposed by considering the balance of air,moisture,internal and external pressure in the cable.Through the implementation of various control technologies,the blistering problem of insulating layer and sheath layer of hot air cured silicone rubber cable was effectively solved,the product quality was improved,and the production cost was reduced.
