Comparative example 4
The difference between the embodiment and the invention embodiment 1 is that the glazing amount is different, and the method specifically comprises the following steps:
the method comprises the following steps: applying a cover glaze to the semi-finished product blank according to a bell jar type glaze pouring process to form a cover glaze layer;
step two: printing patterns on the surface glaze layer in the first step in an ink-jet mode to form a decorative layer;
step three: performing bell-jar type glaze pouring on the decorative layer obtained in the second step to apply the wear-resistant glaze to form a wear-resistant glaze layer, wherein the quality control range of the wear-resistant glaze is 20 g;
step four: and drying and firing the semi-finished ceramic tile in front of a kiln, and then selecting qualified products for polishing and waxing to prepare the ceramic tile B4.

The test result shows that: the wear-resisting property of the marble ceramic tile can reach 4 levels, and SiO is controlled in the formula of the wear-resisting glaze2、Al2O3The mass proportion of CaO is beneficial to improving the wear resistance of the ceramic tileThe wear resistance can be further improved by adding ZrO2 and ZnO in the wear-resistant glaze formula. In addition, the addition of alkaline earth metals such as CaO and BaO in the wear-resistant glaze greatly affects the wear resistance, so that the wear resistance of the ceramic tile is reduced from 4 to 3. The quality range of the wear-resistant glaze also has an influence on the wear resistance, and too low quality can cause the wear resistance to be reduced.
