在去年的多国包装机械展览会的一次技术交流中,意大利的一家公司介绍了一种五层共挤复合片材的生产技术和生产设备,令人耳目一新。这套设备的主要生产过程是这样的;由五台挤出机同时工作,将料挤出,挤出的料流入有五条流道一个出口的连接器。在连接器中,熔融料层合,层合后的料从连接器流出进入模头,再由模唇流出成幅宽为1000毫米,厚度为1.07毫米的片材,通过压光冷却辊滚压,最终拉伸成宽约1200毫米,厚0.3~0.4毫米的片,由收卷装置
In a technical exchange last year at the Multinational Packaging Machinery Exhibition, an Italian company introduced a refreshing new technology and production equipment for a five-layer co-extruded composite sheet. The main production process of this equipment is such that the five extruders work simultaneously to extrude the material and the extruded material flows into an outlet with five runners. In the connector, the melt is laminated, the laminated material flows out of the connector into the die and out of the die lip into a sheet having a width of 1000 mm and a thickness of 1.07 mm, which is rolled by calendering the cooling roll , Finally stretched into a width of about 1200 mm, a thickness of 0.3 to 0.4 mm sheet by the winding device
