增塑剂对PVC电缆料体积电阻率的影响

Effect of plasticizers on volume resistivity of PVC cable materials

通过改变增塑剂添加量,制备了不同增塑剂含量的PVC电缆料,并测试了其体积电阻率,得到PVC电缆料体积电阻率随增塑剂添加量的变化情况。同时,采用不同厂家的PVC树脂制样并进行测试,考察了增塑剂含量变化对不同厂家PVC体积电阻率的影响。

PVC cable materials with different plasticizer contents were prepared by changing the amount of plasticizer,and their volume resistivity was tested.The change in volume resistivity of PVC cable materials with the addition amount of plasticizer was obtained.Specimens were prepared from PVC resins from different manufacturers and were tested.The effect of plasticizer content on the volume resis-tivity of PVC from different manufacturers was investigated.
