preparation example Construction

[0035] Such as figure 2 As shown, a method for preparing a fully polished glazed tile in an embodiment includes the following steps:

[0036] Step S210: Weigh the material of the green body and add water ball milling to obtain the green body slurry. Among them, the material of the body includes the following raw materials by mass percentage: clay 18% to 32%, feldspar 30% to 50%, quartz 20% to 40%, talc 2% to 3% and sodium tripolyphosphate 0.3% ~0.5%. The fineness of the green body slurry is 0.7% to 0.9% after the 250 mesh sieve, and the mass percentage of water in the green body slurry is 32% to 34%.

[0037] Before weighing each raw material in the material of the green body, each raw material needs to be homogenized and piled up stale to stabilize the composition of the raw material and ensure the accuracy of the formula.

[0038] The fineness of the green slurry is 0.7% to 0.9% after the 250 mesh screen, which can make the whiteness of the polished tiles more uniform and the t...

Embodiment 1

[0075] The preparation of the fully polished glazed tile of this embodiment is as follows:

[0076] (1) Homogenize the raw materials in Table 1, Table 2 and Table 3 with an excavator or forklift, and after stacking them stale, weigh the green body materials according to Table 1, and add water to ball mill for 16 hours to obtain green body slurry. Among them, the fineness of the green slurry is 0.7% with a 250 mesh screen, and the mass percentage of water in the green slurry is 32%. The flow rate of the green slurry measured with a Tu-4 viscometer was 40 seconds.

[0077] (2) The green slurry is sprayed and granulated in a spray tower to obtain green powder, wherein the water mass percentage of the green powder is 6.3%, and the particle size is: 40 mesh to 80 mesh. 80%, 2.9% of particles under 100 mesh. The bulk density of the body powder is 0.93 g / ml. After the green body powder is aged at room temperature for 24 hours, it is pressed into a green body by a fully automatic hydrau...

Embodiment 2

[0086] The preparation of the fully polished glazed tile of this embodiment is as follows:

[0087] (1) Homogenize the raw materials in Table 1, Table 2 and Table 3 with an excavator or forklift, and after stacking them stale, weigh the green body materials according to Table 1, and add water to ball mill for 18 hours to obtain green body slurry. Among them, the fineness of the green slurry is 0.9% with a 250 mesh screen, and the mass percentage of water in the green slurry is 34%. The flow rate of the green slurry measured with a Tu-4 viscometer was 50 seconds.

[0088] (2) The green slurry is sprayed and granulated in a spray tower to obtain green powder, wherein the water mass percentage of the green powder is 7.2%, and the particle gradation is: 40 mesh to 80 mesh. 90%, 2% of particles under 100 mesh. The bulk density of the body powder is 1 g / ml. After the green body powder is aged at room temperature for 30 hours, it is pressed into a green body using a fully automatic hyd...

Abstract

The invention relates to a full-glazed tile. A base glaze layer is prepared from the following raw materials in percentage by weight: 15-25% of sodaclase, 5-12% of kaolin, 1-8% of aluminium hydroxide, 25-35% of quartz, 5-15% of talc, 15-20% of zirconium silicate, 0.3-1% of sodium tripolyphosphate and 4-5% of wollastonite; a cover glaze layer is prepared from the following raw materials in percentage by weight: 15-25% of sodaclase, 8-12% of kaolin, 5-9% of aluminium hydroxide, 5-15% of talc, 0.3-1% of sodium tripolyphosphate, 10-25% of potassium feldspar, 3-5% of zinc oxide, 8-20% of wollastonite and 5-18% of dolomite. The whiteness of the full-glazed tile can reach more than 80 degrees. The invention also provides a preparation method of the full-glazed tile.

Description

Technical field [0001] The invention belongs to the field of ceramic building materials, and particularly relates to a fully polished glazed brick and a preparation method thereof. Background technique [0002] Fully polished glazed tiles integrate the advantages of polished tiles and antique tiles. The glazed surface is as smooth and clean as polished tiles. At the same time, the glazed surface is rich in patterns like antique tiles, and the color is thick or gorgeous. It is characterized by transparency and does not cover the bottom. Face glaze and various flower glazes. Fully polished glazed tiles are underglaze colors, which belong to glazed tiles. It is printed after the base glaze is applied, and then a layer of transparent glaze is applied. After firing, part of the entire glaze is thrown away, leaving a part of the surface Glaze layer, printing layer, base glaze. All glazed antique tiles are fired at one time, and polished on the glazed surface is the last process. How...
