Description
Technical Field
The invention relates to a glazed tile with thin broken cracks and a production process thereof.
Background
The crack glaze is an artistic glaze, and the good decorative effect of the crack glaze is deeply loved by people. The ice cracks are widely applied, can be seen everywhere on the table top of a dining table and a shelf of a tea table, and are also used in modern buildings. The reason for the crack formation is that the expansion coefficient of the blank glaze is different, and when the expansion coefficient of the glaze is larger than that of the blank, the glaze surface is subjected to larger tensile stress in the firing process, so that the glaze surface forms cracks. The traditional crackle glaze has high requirements on blank glaze, the glaze layer is required to be thick, the blank body is required to have good strength and low expansion coefficient, when the chemical composition of the blank is changed, the same glaze is applied, cracks can not be formed, or the formed cracks can not reach the expected effect, great uncertainty is provided, great waste is brought to raw materials, the production cost is high, and the large-batch production is difficult to carry out. Therefore, the development of the thin broken type crackle brick which can stably generate crackles, has high production efficiency, low cost and good crackle effect is very necessary, and the requirement of market economic development is met.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a small-crack glazed tile which is low in production difficulty and suitable for large-batch stable production and a production process thereof.
The glazed tile with the thin broken cracks comprises a tile body, wherein a ground glaze and a surface glaze are sprayed outside the tile body in sequence, and the ground glaze comprises the following components in percentage: 30-48% of albite, 5-10% of calcite, 8-10% of zirconium silicate, 6-10% of kaolin, 15-20% of quartz, 3-5% of calcined talc, 8-10% of black mud powder and 8-10% of alumina; the overglaze comprises the following components in percentage: 15 to 24 percent of albite, 46 to 53 percent of potassium feldspar, 3 to 7 percent of wollastonite, 4 to 7 percent of kaolin, 13 to 16 percent of quartz, 2 to 4 percent of dolomite and 1 to 5 percent of black mud powder.
Further, the ground glaze comprises the following components in percentage: 38% of albite, 8% of calcite, 9% of zirconium silicate, 7% of kaolin, 16% of quartz, 4% of calcined talc, 9% of black mud powder and 9% of alumina; the overglaze comprises the following components in percentage: 20% of albite, 50% of potassium feldspar, 5% of wollastonite, 5% of kaolin, 14% of quartz, 3% of dolomite and 3% of black mud powder.
The process for producing the glazed tile with the thin broken cracks comprises the following steps:
A. performing ball milling, sieving and iron removal on the component raw materials of the ground glaze to obtain ground glaze slurry;
B. performing ball milling, sieving and iron removal on the component raw materials of the overglaze to obtain overglaze slurry;
C. applying a bottom glaze to the green brick body;
D. c, spraying surface glaze on the green brick body subjected to the bottom glaze spraying in the step C;
E. and firing the green brick body subjected to overglaze glazing.
In step C, the thickness of the ground coat is 0.1 mm.
In step D, the thickness of the overglaze is 0.2 mm.
The invention has the beneficial effects that: in the invention, the thickness of the glaze layer is thinner, the requirement on the bottom blank is lower, cracks are easy to form, the consumed raw materials are less, and the cost is lower; in the firing process, the surface of the overglaze layer generates larger tensile stress to form cracks, and the base glaze can well cover the base color of the blank body, so that the base and the surface of the cracks are mutually reflected, and the color is more colorful; the glaze cracking degree is controlled by adjusting the glazing thickness, when the glaze layer is thick, the effect that cracks are broken and dense can be achieved, and when the glaze layer is relatively thin, the effects that cracks are scattered and the texture is slender can be achieved.
Detailed Description
The glazed tile with the thin broken cracks comprises a tile body, wherein a ground glaze and a surface glaze are sprayed outside the tile body in sequence, and the ground glaze comprises the following components in percentage: 30-48% of albite, 5-10% of calcite, 8-10% of zirconium silicate, 6-10% of kaolin, 15-20% of quartz, 3-5% of calcined talc, 8-10% of black mud powder and 8-10% of alumina; the overglaze comprises the following components in percentage: 15 to 24 percent of albite, 46 to 53 percent of potassium feldspar, 3 to 7 percent of wollastonite, 4 to 7 percent of kaolin, 13 to 16 percent of quartz, 2 to 4 percent of dolomite and 1 to 5 percent of black mud powder.
Further, the ground glaze comprises the following components in percentage: 38% of albite, 8% of calcite, 9% of zirconium silicate, 7% of kaolin, 16% of quartz, 4% of calcined talc, 9% of black mud powder and 9% of alumina; the overglaze comprises the following components in percentage: 20% of albite, 50% of potassium feldspar, 5% of wollastonite, 5% of kaolin, 14% of quartz, 3% of dolomite and 3% of black mud powder.
The process for producing the glazed tile with the thin broken cracks comprises the following steps:
A. performing ball milling, sieving and iron removal on the component raw materials of the ground glaze to obtain ground glaze slurry;
B. performing ball milling, sieving and iron removal on the component raw materials of the overglaze to obtain overglaze slurry;
C. applying a bottom glaze to the green brick body;
D. c, spraying surface glaze on the green brick body subjected to the bottom glaze spraying in the step C;
E. and firing the green brick body subjected to overglaze glazing.
In step C, the thickness of the ground coat is 0.1 mm.
In step D, the thickness of the overglaze is 0.2 mm.
Because the cracks are generated due to the difference of the expansion coefficients of the blank glaze, the expansion coefficient of the blank is required to be far smaller than that of the glaze, and the surface of the glaze layer generates larger tensile stress in the firing process to form the cracks. It must be considered that the expansion coefficient between the blanks is increased while the blanks are easy to crack under stress. The expansion coefficient of the ground glaze is small and the expansion coefficient of the overglaze is large by applying a layer of ground glaze with the adaptability of the ground glaze on the surface of the blank and applying a layer of overglaze with relative thickness on the ground glaze. Reduction of A1 in overglaze2o3And Sio2Content, increasing content of alkali metal oxide, increasing expansion coefficient of overglaze, controlling ball milling parameters to increase undissolved quartz particles in glaze, increasing probability of converting into cristobalite, and increasing A1 in ground glaze2o3And Sio2The content of the quartz particles in the ground glaze is ensured to be fine, the quartz particles can be dissolved in feldspar solution, and the thermal expansion coefficient of the ground glaze is reduced.
The invention is suitable for the field of production and manufacturing of the glazed tile with the broken cracks.
