挤出压延法生产宽幅胶片的装备研制

The equipment development of wide rubber sheet by extrusion calender

采用挤出压延法生产宽幅胶片,并将传统的"塑炼—压延—成型"过程整合到一条生产线中,可大幅提高宽幅胶片的质量和生产效率;采用双挤出系统、组合式机头和分离式流道板,大幅减低了制造难度;机头采用三维设计,并采用高聚物流变有限元分析软件对物料在机头内的流动进行模拟仿真,大大提高了设计的准确性,缩短了设计周期,降低了研制成本。

Producting wide rubber sheet by extrusion calendering,it integrates conventional 'plasticate-calendering-building' process into one production line,the quality of wide rubber sheet and productivity has risen greatly.Adopt dual extruding system、combination head、separable runner plate,the difficulty of manufacture were reduced.3-D was used in the design of head,adopt polymer rheology nonlinear FEM software to simulate the materiel flow in head,the precision of design has risen greatly,the design cycle is reduced,the development cost is reduced.
