Zusammenfassung: | The invention relates to a molding process of different quantitative mica materials, and the molding process specifically comprises the following steps: pulping: sorting a mica raw material, removing impurities, and then stripping the mica raw material by a hydraulic pulping method to form fine mica scales so as to obtain primary mica slurry; fine selection: separating the mica primary slurry through a cyclone to obtain mica flake slurry meeting requirements, and then dehydrating the mica flake slurry through a fixed screen to finally obtain qualified mica slurry; making paper, namely making the qualified mica pulp into mica paper through a rotary screen paper making machine; the method comprises the following steps of: cutting and pressing, stacking a plurality of pieces of mica paper into a mica plate blank with a certain thickness, coating a layer of glue on the surface of the mica paper before each piece of mica paper is stacked, then cutting off partial thickness of mica paper on the two sides of the mic |
