摘要
对采用负压定径技术生产大管径聚乙烯管的挤出成型工艺及其主要设备进行了研究。工艺参数包括温度、挤出速率、牵引速率,大管径聚乙烯管挤出生产线主要由挤出机、主体模具、负压定径舱、定径装置、二次冷却系统、牵引装置组成。
The extrusion molding process and main equipment for producing PE large diameter pipe with negative pressure sizing technology are studied. The technological parameters include temperature, extrusion speed and traction speed. The extraction production line for PE large diameter pipe is composed of extraction machine, body mould, negative pressure sizing compartment, sizing device, secondary cooling system and traction device.
