摘要
分析了低发泡聚氯乙烯结皮板材的挤出生产技术。在低发泡聚氯乙烯结皮板材生产中,选用螺杆特性硬的双螺杆挤出机、无发泡死角的模头,选用聚合度700~800,K值55~68的PVC原料,以及复合型发泡剂,挤出温度控制在140~160℃,可以生产性能比较优异的制品。
The extrusion technology of skinning foamed PVC sheets was analyzed.In the extrusion of skinning foamed PVC sheets,selection of degree of polymerization in 700~800,K value in the 55~68 PVC raw materials and composite foam,extrusion temperature control in 140~160 ℃,high quality skinning foamed PVC sheets can be produced.
