| 摘要 | PURPOSE:To produce the title steel sheet having excellent resistance to corrosion, heat, wear, and chemicals by applying a specified glaze on the surface of a steel sheet, and drying the glaze. CONSTITUTION:From 3-10 parts (solid component) of the material contg. 40-80% acrylic ester, 5-38% methacrylic ester, 1-5% org. acid-based polymer, and 0.05-0.3% surfactant or 20-40% epoxy resin and 30-50 parts of water are admixed to 100 parts of a frit for lower glazing having >=200 mesh grain size to obtain a glaze. A steel sheet is degreased, pickled, then dipped in an Ni soln., and neutralized, and the glaze is applied on the surface of the steel sheet in about 130mum thickness. The glazed steel sheet is then dried at ordinary temp. to 150 deg.C for 2-60min to obtain a covered steel sheet for enamel. The steel sheet is then formed and calcined at 500-900 deg.C, and an upper glaze is applied, dried, and calcined. | ||||||
