Embodiment 1

[0050] 1. Press bricks.

[0051] 2. Kiln drying, the drying time is 1h, and the moisture content of the dried billet is controlled within 0.5%.

[0052] 3. Spray the surface glaze, the specific gravity of the surface glaze is 1.40, and the amount of glaze applied is 450g / m 2 ; SiO 2 : 58.2%, Al 2 o 3 : 24.16%, Fe 2 o 3 : 0.31%, TiO 2 : 0.14%, CaO: 0.35%, MgO: 0.18%, K 2 O: 4.44%, Na 2 O: 2.73%, ZrO 2 : 6.12%, loss on ignition: 3.37%.

[0053] 4. Inkjet printing pattern.

[0054] 5. Glue spraying glue for digital machine glue machine (purchased from Siti Berndt Company) glue volume 35-60g / m 2 .

[0055] 6. After digital glue spraying, 2-5s inner cloth frit dry granule glaze, the amount of frit dry granule glaze is 900g / m 2 , the chemical composition of frit dry glaze is: SiO 2 : 57.8%, Al 2 o 3 : 7.93%, CaO: 11.01%, MgO: 0.62%, K 2 O: 6.85%, Na 2 O: 1.94%, ZnO: 11.9%, BaO: 1.61%, loss on ignition: 0.34%. The particle gradation of the fritted dry glaze is as f...

Embodiment 2

[0062] Substantially the same as Example 1, the difference is that the chemical composition of the fritted dry granular glaze is: SiO 2 : 56.81%, Al 2 o 3 : 8.95%, CaO: 11.06%, MgO: 0.57%, K 2 O: 6.55%, Na 2 O: 1.65%, ZnO: 11.81%, BaO: 1.36%, loss on ignition: 0.36%.

[0063] Using the chemical composition of the fritted dry glaze, the quality and effect of the brick surface are compared with Example 1, there is no significant difference, the color of the brick surface is bright and pure, and the thickness of the glaze layer on the brick surface reaches 0.2-0.4mm thick after polishing, and it is transparent It has a strong anti-fouling effect, and the glaze layer has almost no fine bubbles when observed through a magnifying glass, and the antifouling effect is very good. There is no water ripple phenomenon of ordinary glazed tiles, and the flatness is very good.

Embodiment 3

[0065] Basically the same as in Example 1, the difference is that the particle gradation of the fritted dry glaze is: 60 mesh: 50.8%, 60-80 mesh: 32.1%, 80-100 mesh: 10.6%, 100-140 mesh: 3.1%, under 140 mesh: 3.4%.

[0066] Dry granules with the same chemical composition as in Example 1, according to the particle gradation, the dry granules are evenly distributed in the production process, and the quality and effect of the brick surface after firing and polishing are compared with those in Example 1. There is no obvious difference, and the color of the brick surface is bright and pure. , After polishing, the thickness of the glaze layer on the brick surface reaches 0.2-0.4mm thick, and it has a strong sense of transparency. The glaze layer has almost no fine bubbles when observed through a magnifying glass, and the antifouling effect is very good. There is no water ripple phenomenon of ordinary glazed tiles, and the flatness is very good.

Abstract

The invention relates to a super flat frit dry granular graze fully-polished brick and a preparation method thereof. The preparation method comprises the following steps: (1) laying a frit dry granular glaze on the surface of a brick blank and fixing the frit dry granular glaze; and 2) conducting firing and polishing on the brick blank obtained in the step (1).

Description

technical field [0001] The invention relates to an ultra-flat frit dry-grain glaze full-throw brick and a preparation method thereof, belonging to the field of ceramic brick production. Background technique [0002] As the main building decoration material, ceramic tiles are widely used in engineering fields and home decoration. Fully glazed ceramic tiles are deeply loved by consumers in the market due to their bright surface. At present, the full glaze of most fully glazed ceramic tiles is mainly produced by spraying glaze or pouring glaze. The thickness of the transparent glaze layer is 0.1-0.2mm, and the wear resistance is worse than that of polished tiles. Therefore, with the use of time Over time, a certain degree of scratches will appear on the brick surface, the brightness will decrease, and even the transparent glaze layer will wear through. The current production method of wet glazing limits the thickness of the transparent glaze layer, and the flatness of the poli...
