▎ 摘　　要

NOVELTY - The method involves cleaning mica raw materials. A water-power crusher is used to crush a mica fluff with different grain diameters to obtain mica flakes with different particle diameters. The mica flour is sieved from -60 mesh to +80 mesh and -160 mesh to -200 mesh. A bone glue solution is prepared for preparing coarse mica powder and fine mica pulp. The coarse mina powder is made into a core paper in a round mesh paper machine. A surface paper is covered on two sides of the composite core paper. The surface paper on the surface of the two sides is covered. The composite and curing process is performed under hot pressing action of a hot pressing roller. The cured product is trimmed to obtain a finished product of high-gram mica paper USE - The method is useful for uniform papermaking of high gram weight mica paper, which is useful in cable, large electromechanical device and large motor. ADVANTAGE - The mica paper: has physical strength, insulating performance, and has good internal uniformity in plane. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a papermaking of high gram weight mica paper. 1First face paper 2Glue layer 3Core paper 4Lower filling part 5Second tissue 6Upper filling part
