Claims8
A ceramic paper manufacturing method comprising:
- (a) preparing raw materials;
- (b) mixing the prepared raw materials to prepare a raw material mixture;
- (c) laminating the raw material mixture on a mesh belt;
- (d) dehydrating the raw material mixture laminated on the mesh belt;
- and
- (e) drying the raw material mixture,
- wherein the raw materials comprise polycrystalline alumina fiber, a binder, retention aids, a dispersant, and a thickening agent, and
- wherein, in step (b), 9,900 to 11,000 parts by weight of water as a solvent, 70 to 95 parts by weight of the polycrystalline alumina fiber, 3 to 18 parts by weight of an organic binder, 3 to 12 parts by weight of an inorganic binder, 2 to 6 parts by weight of polyaluminium chloride (PAC), 1 to 2 parts by weight of cationic-polyacrylamide (C-PAM), 1 to 3 parts by weight of the dispersant, and 0.2 to 2.0 parts by weight of the thickening agent are mixed.
