Description

The invention relates to the building materials industry and can be used in the production of glazed ceramic tiles.

The purpose of the invention is to increase the glacier glaze on ceramic tiles, reducing the cost of frit. - The method is carried out as follows.

Waste bakorovy refractories with an admixture of glass mass (5-10%), formed when replacing the lining of glass melting furnaces, are crushed first in a jaw crusher to pieces 2-3 cm in diameter, and then in a cone inertial crusher or other type to a particle size less than 0.5 mm.

The resulting product has the following chemical composition, May. %:

A120348.0-51.0

CaO0,4-0.8

MDO0,2-0,4

Na202.0-3.2

Zr0230.0-39.0

Рв20з0,1-0,15

According to the mineralogical composition, bakor wastes are represented by baddeleyite 30–40% and corundum 45–50%.

In the charge, the zirconium-containing frits of the zirconium concentrate are partially replaced by ground waste of bakor refractories, while in the oxide composition the frit is replaced by 20-60% ZrO2 through bakor refractories.

All components of the mixture are metered, mixed, melted in a frit-oven at 1350-1400 ° C, granulated in water. Frit is used to prepare the glaze, in the charge composition of which it is introduced in the amount of 95-100%, clay or CMC and NaCl are used as additives. Glazed tiles are burned on flow lines at 900-950 ° C for 30-40 minutes.

The invention is illustrated by specific examples in the table.

The proposed method for manufacturing a fritted frit allows to obtain an glaze coating on ceramic tiles with a high degree of clutter with a reduced consumption of scarce zircon concentrate and recycling of secondary raw materials - zirconium-containing waste of bakor refractories.
