Embodiment 1

[0036] Refer to attached figure 1 , the present embodiment provides a kind of tile product, and its order from bottom to top is green body layer 101, bottom glaze layer 201, surface glaze layer 301, printing layer 401, and wherein the thickness of bottom glaze layer is about 0.2mm, and surface glaze layer The layer thickness is about 0.1 mm.

[0037] The preparation method includes the following steps.

[0038] (1) Raw materials are ball milled to remove iron.

[0039] In this step, the conventional formula in the tile production technology can be selected. That is to say, the raw materials with feldspar, quartz, clay, talc and other conventional raw materials as the main components are ball milled, iron removed and stale homogenized.

[0040] (2) Spray granulation.

[0041] The stale homogenized slurry after iron removal in step (1) is put into the spray drying tower for spray granulation, and after spray granulation, granular powder is formed, and the moisture content of...

Embodiment 2

[0062] Refer to attached figure 2 , the present embodiment provides a kind of tile product, and it is body layer 101, bottom glaze layer 201, printing layer 401, surface glaze layer 301 successively from bottom to top, wherein the thickness of bottom glaze layer is 0.4mm, and the thickness of surface glaze layer is 0.4mm. 0.2mm, the top glaze layer is transparent glaze.

[0063] The preparation method of this embodiment is basically the same as that of Example 1, except that: 1. The amount of glaze used for spraying glaze on the bottom glaze layer is about double that of Example 1. 2. After the bottom glaze layer is formed, first perform inkjet printing to form the printing layer 401, and then spray the surface glaze layer. The surface glaze layer is transparent glaze, and the thickness of the surface glaze layer is 0.2mm. The transparent glaze dry material components are: 95% transparent frit produced by Guangdong Sanshui Dahong Glaze Co., Ltd., and 5% kaolin. When ball mi...

Embodiment 3

[0066] Refer to attached image 3 , in order to protect the printing layer, the present embodiment provides a kind of tile product, which is successively green body layer 101, bottom glaze layer 201, surface glaze layer 301, printing layer 401, transparent glaze protection layer 501 from bottom to top, wherein The thickness of the bottom glaze layer 201 is 0.1 mm, the thickness of the top glaze layer 301 is matt glaze, and its thickness is 0.05 mm, and the thickness of the transparent glaze protective layer 501 is 0.1 mm.

[0067] Its preparation method is basically the same as that of Example 1, except that the amount of bottom glaze and top glaze is about half of that of Example 1, and its thickness is also half of that of Example 1. Add a step of applying a transparent glaze protective layer on the printing layer, and the components of the transparent glaze are the same as those in Example 2. The dosage is about 15.5g / tablet.

[0068] In this embodiment, although a step o...

Abstract

The invention provides a ceramic chip and a manufacturing method thereof. The ceramic chip comprises a blank body layer, a ground coat layer, a surface glaze layer and a printing layer, wherein the thickness of the ground coat layer is 0.1-0.4mm, and the thickness of the surface glaze layer is 0.05-0.2mm. The manufacturing method of the ceramic chip comprises the following steps of raw material ball-milling and deironing, spray granulation, powder punch forming, bisque firing, ground coat applying, surface glaze applying, printing, secondary glaze firing, and sorting and classifying, wherein the thickness of the ground coat layer formed by the ground coat applying step is 0.1-0.4mm, the thickness of the surface glaze layer formed by the surface glaze applying step is 0.05-0.2mm, and the ground coat applying step and the surface glaze applying step are realized by a glaze spraying manner. A thinner glaze layer can releaseieve a crack defect caused by a blank and glaze matching problem, can also emphasize a stereo line effect of a blank body and can solve a glaze breakage defect caused by overlarge undulation of stereo lines. According to the ceramic chip and the manufacturing method thereof, disclosed by the invention, the blank body has high water absorption and is paved on a high place in a cement mortar adhering manner, so that the safety is ensured, the construction is convenient and quick, the construction period is short and the cost is low.

Description

technical field [0001] The invention relates to the technical field of building ceramics production, and more particularly relates to a tile and a manufacturing method thereof. Background technique [0002] In the field of architectural ceramics production technology, tiles refer to ceramic bricks with a glazed layer on the surface. The water absorption rate of the bricks is generally 10-18%. After the bisque is glazed, printed and other processes, it is fired for the second time. Of course, there are also multiple firing processes that are greater than two firings. For example, waistline tiles that require multiple glazes will be fired three or more times. As introduced in the invention patent with the application number 200910041423.7, the glazing process in the existing porcelain production process is the method of glazing, which is mostly the bell-type glazing process. Of course, the adoption of the above process is mainly related to the application range of the tiles....
