分析了聚偏氟乙烯(PVDF)试制生产工艺流程和生产工艺控制要点,探讨了挤出加工温度对管材性能的影响,确定PVDF的加工工艺,并对试制产品的性能进行了检测。检测结果表明,PVDF产品具有良好的机械性能和良好的热性能,同时还具有良好抗蠕变性能和抗老化性能、极低的渗透性,能够满足海底复合软管的使用要求。
The key points of production process and production process of PVDF were analyzed. The influence of extrusion processing temperature on the properties of the pipe was discussed. The processing technology of PVDF was determined and the performance of the prototype was tested. The test results show that PVDF products have good mechanical properties and good thermal properties, but also have good creep resistance and anti-aging properties, low permeability, to meet the requirements of submarine composite hose.
