A peeled marble tile with peeled glaze and no glaze defects and its preparation process

Abstract

The invention discloses a stripping glaze, a stripping-glaze marble ceramic tile without glaze defects and a preparation process of the marble ceramic tile. The stripping glaze comprises the followingraw materials in percentage by mass: 18-22% of potassium feldspar, 4-6% of water washed ball clay, 25-30% of quartz, 25-30% of wollastonite, 5-8% of limestone, 5-8% of zinc oxide and 10-12% of corundum powder. According to the stripping glaze used for preparing the stripping-glaze marble tile provided by the invention, the high-temperature viscosity of the stripping glaze in a high-temperature molten state is improved, and therefore the stripping-glaze marble tile without the glaze defects and of which glaze stripping effects are more vivid and natural is obtained by adopting a glaze sprayingmode.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a peeled marble tile with peeled glaze and no glaze defects and a preparation process thereof. Background technique [0002] Since the performance and process characteristics of the glaze slurry often determine the choice of spraying or pouring glaze, the current peeling glaze glazing process usually uses a high-pressure water jet machine to atomize the glaze slurry and spray it on the brick surface, and cannot The reason for adopting the method of pouring glaze is that the existing peeling glaze has low viscosity and high fluidity when fired at high temperature, which easily causes the peeled place to be completely melted and flattened. However, when choosing the glaze spraying method, the glaze spraying often limits the thickness of the glaze layer, that is, it is difficult to meet the production requirements due to the thinner glaze layer, and it is easy to prod...

Problems solved by technology

[0002] Since the performance and process characteristics of the glaze slurry often determine the choice of spraying or pouring glaze, the current peeling glaze glazing process usually uses a high-pressure water jet machine to atomize the glaze slurry and spray it on the brick surface, and cannot The reason for adopting the glaze method is that when the existing peeling glaze is fired at high temperature, its viscosity is low and its fluidity is high, which easily leads to the complete melting of the peeled off area

However, when choosing the glaze spraying method, the glaze spraying often limits the thickness of the glaze layer, that is, it is difficult to meet the production requirements due to the thinner glaze layer, and it is easy to produce problems such as yellow edges, missed throwing and throwing through during polishing, and due to The glaze layer of spray glaze is relatively thin, and the dust formed by spray glaze will cause environmental pollution and harm the health of employees

However, if you want to increase the amount of glaze spraying, it will easily lead to the phenomenon of brick explosion caused by excessive water; and in the process of spraying, due to the uneven atomization of the glaze slurry, it is easy to cause dripping glaze and uneven thickness of the glaze layer on the left and right sides. Uniformity, foaming, pinholes, etc.
