Embodiment 1
[0042] A preparation method for an enamel plate for a flue of a thermal power plant, comprising the following steps:
[0043] (1) Preparation of enamel glaze:
[0044] a. Mix raw materials: Mix the raw materials for preparing enamel glaze in solvent water evenly; the raw materials for preparing enamel glaze are composed of the following compounds in parts by mass: 100 parts of glaze, 30 parts of quartz, and 1 part of borax , 1 part of barium nitrate, 7 parts of clay, 0.5 parts of sodium nitrite, and 45 parts of water; wherein, the glaze consists of the following compounds in mass percentage:
[0045]
[0046]
[0047] b. Melting: Put the uniformly mixed above-mentioned raw materials into a crucible, and melt at 1200°C for 3 hours;
[0048] c. Chilling: Put the above-mentioned melted raw materials into water and cool them down to room temperature quickly. After the raw materials cooled to room temperature are taken out, they are dried at 100°C for 4 minutes to solidify t...
