How to Produce Filter Plate

Generally, the main components of the current plastic filter plateare polypropylene (C3H6nCAS), antioxidant, glass fiber, curing agent and other raw materials. After pre-treatment, breaking and mixing, the various components are evenly distributed. Let the polypropylene raw material be heated and melted. At 260°C~280°C, the polypropylene is stirred, heated and expanded to form a polypropylene viscous liquid. After 20~30 minutes of heating, the polypropylene viscous liquid will be It's time for the next styling.

The shape of the filter plate is the abrasive tool used, so before manufacturing the filter plate of the filter press, it is necessary to make the required filter plate mold of the filter press. Different sizes, thicknesses, and styles will have different casting molds. The polypropylene liquid is introduced into the mold, and the upper mold is pressed by a hydraulic press of several tens of MPa, so that there is no air hole in the middle of the manufactured filter plate, which increases the compactness of the filter plate. Then fix the upper and lower molds, remove the hydraulic press, store it at room temperature, wait for it to cool down, and fix the form.

The filter plate of such a filter press is basically completed. After the filter plate is cooled, a little processing will be done. Such as making water holes, upper handles, deburring, watering, etc. This is such that the filter plate can be placed on the beam of the filter press, and the filter cloth can be used.
