Embodiment 1
[0022] Ingredients:
[0023] Metallurgical comprehensive wastewater sedimentary sludge powder made after drying the sedimentary sludge of comprehensive metallurgical wastewater: 80 parts by weight
[0024] Modifier D: 10 parts by weight, wherein the mixing weight ratio of potassium feldspar and spodumene is 5:1
[0025] Modifier C: 10 parts by weight of diopside
[0026] Process method:
[0027] refer to figure 1 , the above ingredients are mixed and sent to a ball mill for mixing and granulation to make fine and uniform particles with a particle size of 0.5 mm and then aged for 48 hours; then sent to a mold for compression molding; after drying, bisque firing and glazing are carried out to obtain The adobe of colored glaze floor tiles is sent to a roller kiln for firing at a firing temperature of 1120°C with a cycle of 60 minutes, so that the adobes can fully undergo physical and chemical changes to obtain colored glaze floor tiles.
[0028] The samples of the above-menti...
