Description

oo e

The invention of the invention relates to ceramics industry and can be used in the production of facing tiles for interior wall cladding. Known charge Cl3 for the manufacture of facing tiles, including the following components, wt.% Clay 24-32 Quartz sand 17-23 Kaolin 18-22 Bentonite2-4 Perlite8 12 Chamotte, 9-11 Dolonit or known to 8-12 The disadvantage of this composition The batch is to produce tiles with low heat resistance. Closest to the invention is a batch of 2J for the manufacture of ceramic products, including the following components, wt% Clay Kaolin Quartz-feldspar sand Lerlite-Tufolava Hedetstatka of the known charge is relatively low heat resistance and strength, significant deformation and water absorption of the tiles. The purpose of the invention is to increase the heat resistance and strength, reducing the deformation and water absorption of tiles. This goal is achieved by the fact that the charge for production of the facing tiles, including clay, perlite and tufolava, contains additional no. bentonite and porcelain battle at the following ratio of components, wt,%: Clay25-42 Perlite1-12 Tufolava38-53 Bentonite1-4 Porcelain battle7-17 Weakly argylized tufolava, so-called Bektakar stone, contains rock-forming minerals,% quartz 65-70; feldspar 25-30 and clayey matter 15-20. Facing tiles are made according to the following technology. The components of the charge are crushed to fineness, ensuring the perforation through a 006 sieve with a residue on a sieve of 2-3%, then the slip mass is dried to a moisture content of 6-7%, and from the obtained powder the tiles are pressed on a KPAS-125 press. The tiles are fired on flow-automated conveyor lines at E50-1050 ° C and, after the glaze cover has been applied, a re-watered baking is performed. The composition of the mixture for the manufacture of tiles are presented in Table. 1, Properties of facing tiles are given in table. 2, As can be seen from the table. 2, facing tiles from the proposed charge possess high rates of heat resistance and strength, as well as low rates of water absorption and deformation. The economic effect from the use of this mixture for the production of internal facing tiles will be about 50 thousand rubles. per year with a productivity of 750 thousand, m of tiles. , Table 1
