Problems solved by technology

Although this kind of glaze is less radioactive as a bottom glaze, there are more phase-separated droplets in the glaze, and the phase-separated droplets on the surface of the bottom glaze layer are easy to wrap the coloring pigment in the ink. As a bottom glaze for inkjet printing, there is still zirconium. The same problem as the base glaze, that is, the color of the ink is not good, and the amount of ink needs to be increased to achieve the desired effect. This not only wastes ink, but also increases the probability of nozzle clogging, and also has a certain impact on production color matching

Embodiment 1

[0023] In this embodiment, boron-calcium opacified glaze is selected as the bottom glaze, which contains 0.5% by mass of anatase titanium oxide.

[0024] The chemical composition of the bottom glaze is as follows: silica 55.5%~61.5%; alumina: 8.5%~11.5%; iron oxide: ≤0.09%; calcium oxide: 7.5%~12.5%; boron oxide: 7.5%~10.5% Magnesium Oxide: ≤1.0%; Sodium Oxide: 1.0%~2.0%; Zinc Oxide: 5.0%~6.0%; Potassium Oxide: 9.0%~10.0%; Lithium Oxide: ≤1.0%; Anatase Titanium Oxide: 0.5% .

[0025] Calculate the raw material formula used according to the above formula ratio, choose potassium feldspar, quartz powder, wollastonite, kaolin, talc, boron frit, anatase type titanium oxide, zinc oxide, etc. as raw materials in this embodiment, add water ball mill, in During ball milling, 0.03% to 0.05% carboxymethyl cellulose and 0.1% to 0.3% sodium tripolyphosphate should be added to the glaze dry material. The remaining 1-2% of the 325 mesh sieve of the glaze slurry after ball milling, fluidity...

Embodiment 2

[0036] It is basically the same as Example 1, except that the bottom glaze used is a boron-phosphorous multiphase opacified glaze, and the mass fraction of anatase titanium oxide is 1.0%. It has been disclosed in the background art in B 2 o 3 / P 2 o 5 When the mass ratio is 1, there are relatively more phase-separated droplets in the glaze, the size of which is similar to that of visible light, and the dispersion is high, so that the glaze has a strong ability to refract and scatter light, and the glaze surface presents a high opalescent effect. The chemical composition is as follows:

[0037] Silica 55.5%~61.5%; Aluminum oxide: 8.5%~11.5%; Iron oxide: ≤0.09%; Calcium oxide: 1.5%~2.5%; Phosphorus pentoxide: 5.0%~9.5%; Boron oxide: 5.0% ~9.5%; Magnesium Oxide: ≤1.0%; Sodium Oxide: 1.0%~2.0%; Zinc Oxide: 5.0%~6.0%; Potassium Oxide: 9.0%~10.0%; Lithium Oxide: ≤1.0%; Anatase Titanium Oxide : 1.0%.

[0038] Calculate the raw material formula used according to the above formula...

Embodiment 3

[0041] It is basically the same as Example 1, except that the mass fraction of anatase titanium oxide in the bottom glaze is 1.5%.

[0042] The chemical composition of the bottom glaze is as follows: silica 55.5%~61.5%; alumina: 8.5%~11.5%; iron oxide: ≤0.09%; calcium oxide: 7.5%~12.5%; boron oxide: 7.5%~10.5% Magnesium Oxide: ≤1.0%; Sodium Oxide: 1.0%~2.0%; Zinc Oxide: 5.0%~6.0%; Potassium Oxide: 9.0%~10.0%; Lithium Oxide: ≤1.0%; Anatase Titanium Oxide: 1.5% .

[0043] The production test shows that the production of the selected standard color palette requires about 6.8g / piece of ink; 10 shifts of continuous production, and 0 inspections due to nozzle blockage.

Abstract

The invention provides a glazed brick production process, belonging to the technical field of building ceramic production. The production process comprises the steps of forming cloth material, applying ground coat, printing, applying cover glaze, sintering, polishing and grinding, wherein ground coat used in the ground coat applying step is phosphor-boron or boron-calcium multiphase opaque glaze, and the ground coat contains 0.5%-3% (in percent by mass) of anatase titanium oxide and 0.5%-5% of attapulgite. Compared with the prior art, the glazed brick production process provided by the invention has the advantages that the glazed brick production process is less in ink dosage, clear in color, and almost free of chromatic aberration color cast; moreover, inkjet blocking probability is lowered, cleaning and maintaining times of a spray head are reduced, production continuity is improved, and a situation of midway downtime rarely happens except from necessary maintenance.

Description

technical field [0001] The invention relates to the production technology of architectural ceramics, in particular to a production technology of polished glazed bricks. Background technique [0002] Polished glazed tile is a popular ceramic wall and floor tile product in recent years. It is printed with a bottom glaze on the brick, and then a layer of transparent top glaze is applied. After firing in the kiln, the transparent top glaze layer Polishing to obtain glazed tile products. It has the effect of in-glaze color, and the printing layer is basically not worn under the protection of the transparent glaze layer; and after polishing, the product has high gloss and good decorative effect. [0003] Inkjet printing technology is the third-generation printing technology after roller printing and screen printing. It uses an inkjet printer to print patterns on bricks according to preset patterns. At present, the inks used in ceramic inkjet printers are mostly oil-based inks, w...
