| 挤塑板生产设备由两组挤出机串联而成，主要设备有喂料系统；75平行双螺杆挤出机；换网器；150挤出机；发泡剂高压注入系统；模具；定型牵引机组；输送架；边条切割机；长度切割锯组成。辅助设备还有挤塑板表面拉毛机；回收造粒机；边缘成型机；开槽机；自动包装机等。 The Extrusion board production equipment consists of two groups of extruders in series, the main equipment is feeding system; 75 parallel twin-screw extruder; screen changer; 150 extruder; high-pressure injection system of foaming agent; mold; set traction unit; conveying frame; edge cutting machine; length cutting saw. The auxiliary equipment includes the surface roughing machine of Extrusion board, the recycling granulator, the edge molding machine, the slotting machine, the automatic packaging machine, etc. 挤塑板的生产工艺包括以下方面：通用级聚苯乙烯与成核剂、助燃剂等通过喂料机进入第一级塑料挤出机，在挤塑机内充分塑化后再注入发泡剂（常用的是氟利昂，环保型的二氧化碳发泡剂也在逐步推广中），发泡剂在第二级挤出机中与其他原料充分混合和冷却后通过模具挤出，在模具挤出后压力迅速释放，被塑料包裹的发泡剂迅速膨胀形成密闭的泡孔，在泡孔的作用下聚苯乙烯塑料形成了有蜂窝状密闭泡孔的发泡板。再经过定型牵引机将板材定型为所需的厚度和宽度，经过切割成型即可。 The production process of extruded board includes the following aspects: general polystyrene and nucleating agent, combustion supporting agent, etc. enter the first stage plastic extruder through the feeder, fully plasticize in the extruder, and then inject the foaming agent (Freon is commonly used, environmental friendly carbon dioxide foaming agent is also gradually promoted), and the foaming agent is fully mixed and cooled with other raw materials in the second stage extruder Through die extrusion, after die extrusion, the pressure is released rapidly, and the foaming agent wrapped by plastic expands rapidly to form a closed bubble hole. Under the action of bubble hole, polystyrene plastic forms a bubble plate with honeycomb closed bubble hole. After that, the plate is set to the required thickness and width by the setting tractor, and then it can be cut and formed. |
