The specific embodiment
The utility model adopts following production method, comprises following steps.
A, production plane adobe body, as end base, spray one deck ground-coat enamel on base substrate.
B, on ground-coat enamel, spread one deck color grains, form color grains layer.
C, on color grains layer, spray layer of transparent cover-coat enamel, form transparent cover coat, then burn till finished product.
Wherein, the raw material weight ratio of color grains is: potassic feldspar 15-20%; Quartzy 10-15%; Zinc oxide 8-10%; Lithium carbonate 5-7%; Chromium carbonate 1-2%; Titanium oxide 10-15%; Manganese oxide 1-3%; Kaolin 10-20%; Brium carbonate 12-22%; Schweinfurt green 3-6%.
Wherein, the part by weight of ground-coat enamel is: lithium porcelain stone 10 ~ 25%, albite 15 ~ 25%, calcined kaolin 5 ~ 20%, titanium oxide 5 ~ 15%, lithium carbonate 5 ~ 15%, diopside 1 ~ 5%, frit 4 ~ 15%, wollastonite 5 ~ 10%.
Color grains in this step B is that the pre-burning of regeneration tcrude ore forms, and granular size is between 12 order to 40 mesh sieves.
Step C burns till in finished product process, and its temperature is 1190 ℃-1215 ℃.
Steps A is made base substrate by base substrate powder, and it is 6.5% ~ 8.5% that the moisture content of described base substrate powder accounts for base substrate powder quality ratio, and base substrate powder fineness is 250 mesh screen residues 0.8 ~ 1.0%;
In step C, spraying the transparent glaze slip fineness that transparent cover coat uses is 325 mesh screen residues 0.4 ~ 0.6%.
The coefficient of thermal expansion of the base substrate that steps A forms is 6.3 * 10
-6℃
-1, the coefficient of thermal expansion of the transparent cover coat in step C is 5.9 * 10
-6℃
-1.
As shown in Figure 1, in said method, for a kind of, there is colors changing hue glaze layer green compact of ceramic tile structure burning till prerequisite, it has end base 1, base 1 top in the end arranges ground-coat enamel 2, ground-coat enamel 2 tops arrange color grains layer 3, and color grains layer 3 has some color grains 31, and color grains layer 3 top arrange transparent cover-coat enamel 4.With this end base, burn till, can obtain as shown in Figure 2 a kind of and there is colors changing hue glaze layer ceramic tile, it has end base 1, base 1 top in the end is decorative layer 5, this decorative layer 5 comprises transparent cover-coat enamel 4, ground-coat enamel 2 and the colored explosion particle 32 merging, this colour explosion particle 32 adds thermosetting by color grains 31, above-mentioned transparent cover-coat enamel 4, ground-coat enamel 2 and colored explosion particle 32 mutually blending penetrate, but, its decorative layer the top is that transparent cover-coat enamel 4, bottom are ground-coat enamel 2, and ground-coat enamel 2 is connected with end base 1.The not flat structure that transparent cover-coat enamel 4 external surfaces in ceramic tile top are sharp-pointed water caltrop, the similar puffed rice of visual effect, the structure that it has concaveconvex structure and has smooth feel.Its visual effect is the stereoeffect of radial color grains change, obtains colorful glazed ceramic wall tile.
Colored explosion particle, below transparent cover-coat enamel, and has in explosion particle particle gap from the ground-coat enamel that infiltration comes up below, forms change blending effect.
Be below specific embodiment:
Embodiment 1.
