| Abstract: | In order to overcome the shortcomings of plate-and-frame which is made of cast iron or rubber, wood, common plastics, the authors have developed a new kind of material for making plate-and-frame. The polypropylene (PP) plate-and-frame strengthened by siliceous limestone has high mechanical strength and good resistant properties to chemical corrosion. This material is get from PP resin, siliceous limestone activated by coupling agent KH-550 and other assistant agents by means of mixing melt-plastieising. The producing process is extruding-die casting integrally at one time. The working properties of the press filter fitted with this kind of plates and frames are good. It is convenient to fit and dismount, and saving on filter cloth. |
