压滤机滤板也称为复合滤芯板、聚丙烯滤板、隔膜滤板、压滤机过滤板,是采用超高分子量聚乙烯或聚丙烯树脂,并加入各种常用的助剂、抗氧化剂、交联剂混合经模压成型。模压压滤机滤板成型设备,常用1000吨、1200吨、1500吨、2000吨、2500吨等四柱液压机,采用预压、模压和保压三个阶段的压力设计并由时间分段加压进行科学分配,使设备的能量效率更加显著,成型压力高,可靠,保证了热压成型材料的成型质量,全自动制作设备自动化程度高、生产周期短、生产效率高。
2000 tons of four-column hydraulic press hot molding filter press filter plate forming process:
1. Put the dough-like raw materials processed from the extruder into the lower mold cavity of the hydraulic press, and place the raw materials evenly;
2. After feeding, start the machine to close the male mold and the female mold. The action changes from fast to slow slowly. After the mold is closed, the pressure can be increased to heat and pressurize the raw materials;
3, to avoid the product internal stratification and bubbles need to return the hydraulic press exhaust action, exhaust operation can shorten the curing time and improve the physical and mechanical properties of the product;
4, in the molding temperature to maintain a period of time thermosetting plastic curing;
5, 2000 tons of four-column hydraulic press lower top cylinder top demoulding take material;
6. The filter plate of the finished filter press after demoulding can be taken out for trimming and post-processing.
First, polypropylene is heated and melted and extruded, and the weight of the extruded material is also different according to the size of the filter plate. The polypropylene that meets the weight standard is introduced into a 2000-ton four-column hydraulic press, the formed filter plate is taken out and cooled, and then the completely cooled semi-finished filter plate is placed on a full-automatic numerical control machine tool for processing, so that the size and shape of each piece are consistent. After trimming, punching and other operations, the finished filter plate is like this. The process seems simple, but the details need to be controlled accurately.
2000吨压滤机滤板模压成型液压机采用三梁四柱式结构设计,设备主要由主机及控制机构两大部分组成。液压机主机部分包括液压缸、 横梁、立柱及充液装置等。动力机构由油箱、高压泵、控制系统、电动机、压力 阀、方向阀等组成。液压机具有独立的动力机构和电气系统,采用按钮集中控制,可实现调整、手动及半自动三种操作方式。2000吨压滤机滤板模压成型液压机工艺动作顺序为滑块:快下—慢下加压—保压延时--排气--卸压延时--回程。设备效率更加显著,成型压力高,可靠,保证了热压成型材料的成型质量。压滤机滤板成型液压机自动化程度高、生产周期短、生产效率高。配PLC伺服控制系统,精密度高,效率高,节能、环保等优点。
Selection of filter plate hydraulic press machine:
通常1.5米的滤板使用800吨液压机,1.6米的滤板使用1000吨液压机,2.5米左右的使用2000T液压机。
