Glazed tile surface treatment method and application

Abstract

The invention relates to the technical field of ceramic processes, and particularly discloses a glazed tile surface treatment method and application. The glazed tile surface treatment method comprises the following steps of mixing potassium salt, an adsorbent and an activating agent, and heating to a molten state to obtain a molten salt mixture, immersing the glazed tile in the molten salt mixed solution for surface treatment and then taking out, and acquiring the glazed tile with the surface treated. The glazed tile is immersed in the low-temperature molten salt mixture, alkali metal ions in the glaze layer and alkali metal ions in the molten salt mixture are subjected to ion exchange due to mutual diffusion, and pressure stress is generated on the surface of the glaze layer, so that the wear resistance of the glaze surface is enhanced. The adsorbent can adsorb impurity ions in the glaze layer, the activator is used for eliminating passivation of the potassium salt in the ion exchange process, so that the ion exchange rate is further improved, the wear resistance of the glazed tile is jointly enhanced through the synergistic interaction of the potassium salt, the adsorbent and the activator, and the glazed tile is suitable for surface treatment of glazed ceramic.

Description

technical field [0001] The invention relates to the technical field of ceramic technology, in particular to a surface treatment method and application of a glazed tile. Background technique [0002] Glazed tiles are ceramic tiles whose surface is glazed and fired at high temperature and pressure. Glazed tiles can be applied to a variety of decorative means, and are richer in colors and patterns than polished tiles. The main disadvantage is that they are not resistant to wear. Due to the existence of the glazed layer on the surface of the glazed tile, its hardness is not high and its wear resistance is poor, so its use is limited, especially when it is used as a floor tile, it is prone to scratches, and it is not suitable for use in public places with large traffic. [0003] At present, there are mainly the following methods for enhancing the surface wear resistance of glazed tiles in the prior art: the first is to add ultra-fine alumina or aluminum hydroxide wear-resistant ...

Problems solved by technology

Glazed tiles are suitable for a variety of decorative methods, and are richer in color and pattern than polished tiles. The main disadvantage is poor wear resistance.

Due to the existence of the glaze layer on the surface of glazed tiles, its hardness is not high and its wear resistance is poor, which limits its use, especially when used as floor tiles, it is prone to scratches and is not suitable for use in public places with a large flow of people

[0003] At present, there are mainly the following methods for enhancing the wear resistance of glazed tiles in the prior art: the first is to add ultra-fine alumina or aluminum hydroxide wear-resistant media to the glaze to improve the wear resistance of the glazed surface, but this The preparation process of this method is very complicated: one is to control the particle size of alumina or aluminum hydroxide, if it is too fine, it will be dissolved in the glass phase, and if it is too thick, it will form protrusions on the glaze; the other is to control the cooling system, the cooling system It will affect the crystallization; the third is to consider the ratio of the various components in the glaze, so that the required wear-resistant crystal phase is precipitated during the cooling process; the second is to add frit to the transparent glaze to improve the wear resistance of the glaze. This method has high requirements on the quality of the frit, which has a great influence on the melting temperature range of the glaze and the gloss and whiteness of the glaze, which is not easy to control
