(1) mixing

1、氯化聚乙烯的主链不含双键，机械塑料时主链不易切断，对其门尼粘度几乎没有影响，因此无需塑炼。

1, the backbone of chlorinated polyethylene containing double bond, mechanical plastic backbone is not easy to cut, almost no influence on the Mooney viscosity, so no plastication.

2、CPE胶既适宜开炼机混炼，又适宜密炼机混炼。用开炼机混炼之前，由于CPE为粉状，需先将CPE在70℃至90℃开炼机上薄通塑炼成半透明状，再进行混炼。CPE胶用密炼机混炼时，混炼胶的温度应控制在130℃～150℃范围为宜。如果将过氧化物直接加到密炼机中进行混炼，则密炼机温度要控制在过氧化物"起硫"温度以下。另外，CPE胶用密炼机混炼时，应有足够的装胶容量，一般应在95%以上。

2, CPE glue is suitable for mixing machine, but also suitable for mixing mixer. Before mixing with the mixer, due to the CPE powder, the need for the first CPE in 70 to 90 degrees Celsius on the mixer to thin plastic into a translucent, and then mixed. When the CPE glue is mixed with a mixer, the temperature of the mixture should be controlled in the range of 130 DEG C to 150 C. If the peroxide is directly added to the mixer for mixing, the temperature of the mixer is controlled below the temperature of the peroxide. In addition, CPE glue mixer mixing, there should be enough capacity to install glue, generally more than 95%.

（二）挤出

(two) extrusion

CPE抗焦烧性良好，可以挤出表面光滑的线缆产品。挤出机螺杆长径比小于12时，挤出有相当的难度。采用热喂料挤出，可改善线缆表面质量。当长径比大于12时，冷挤、热剂均能挤出表面光滑的线缆。在挤出温度方面由于CPE流动性不如CR好，塑化不易，因此在挤出时，机身温度控制在75℃～85℃；机头温度控制在85℃～95℃为宜。EV-SS充电桩电缆

CPE good scorch resistance, can squeeze out the smooth surface of cable products. Extrusion screw length diameter ratio is less than 12, extrusion is quite difficult. Hot extrusion can improve the surface quality of cable. When the ratio of length to diameter is greater than 12, the cold extrusion and heat agent can extrude smooth cables. In the extrusion temperature due to the CPE mobility is not as good as CR, plasticizing is not easy, so in the extrusion, the temperature of the body is controlled at 75 DEG C to 85 DEG C; the head temperature control in the temperature of 85 DEG C to C.

（三）硫化

(three) vulcanization

CPE适用于管道连续硫化。为了保证生产效率，提高硫化温度是必要的，一般在1.2～2.0MPa蒸汽压力下可连续硫化。温度过低，硫化体系用量不足或者水冷却段太短或无水冷却段，则易产生气泡。另外，CPE属于热敏性材料，在挤出和硫化阶段都应控制温度，温度过高，则易产生气孔。

CPE suitable for continuous vulcanization. In order to ensure the production efficiency, it is necessary to improve the curing temperature, which can be cured at 1.2 ~ 2.0MPa steam pressure. If the temperature is too low, the dosage of the curing system is insufficient, or the water cooling section is too short or the water cooling section is not enough, the bubble is easy to generate. In addition, CPE belongs to the heat sensitive materials in extrusion and curing stage should
