压滤板又称为聚丙烯过滤板、压滤机滤芯板、压滤机滤板、隔膜过滤板，是采用超高分子量聚乙烯树脂，并加入助剂等，配合压滤板模具，在高温高压下，一次模压成型。压滤板/压滤机滤芯板生产设备称之为压滤机滤板模压成型液压机，根据压滤板的规格尺寸，常用有800吨、1000吨、1250吨、1500吨、2000吨、2500吨等四柱液压机，是一款多功能型三梁四柱液压机，可根据工艺需求，合理设计压滤板/压滤机滤芯板所需的工作台面、开口、行程等。
The 1500-ton filter press plate/filter press filter element plate molding hydraulic press is mainly used for the overall molding of thermosetting (glass fiber reinforced plastic) plastic products and thermoplastic plastic products. There are four column type, frame type two kinds of structure for choice,. It has independent hydraulic pump station and numerical control electric control system. The hydraulic control adopts a cartridge valve integrated system, the overall body has compact structure, reliable action, good sealing performance, long service life, and convenient installation and maintenance. Filter press plate/filter press filter element plate production equipment-the electrical system of the 1500-ton four-column hydraulic press adopts button centralized control, and is equipped with three operation modes of inching, semi-automatic and fully automatic. The working pressure and working stroke can be adjusted arbitrarily according to the needs, and can complete the two forming methods of working constant pressure and working process.
Process flow of 1500 ton four-column hydraulic press molded filter press plate/filter element plate of filter press:
1. Ingredients: First, the filter plate raw materials are proportioned, mixed, stirred at high speed, and dried;
2. Extrusion: The dried raw materials are added to the extruder. After extrusion, granulation, drying, and re-extrusion, the extruder is heated in sections;
3. Weighing: The extruded material is weighed by an electronic scale and sent to a numerical control insulation box for preservation. When the box reaches 2-4 pieces;
4. Molding: The raw materials in the box are added into the mold and pressed into a hydraulic press (1500-ton four-column hydraulic press) by pressing the filter plate/filter element plate;
5. Heat preservation and pressure keeping for 4-5 hours to obtain the finished product, which can be used;
