Description

Изобретение относится к технологии силикатов, а именно к производству глазури, которая может быть использована для покрытия плиток, керамических изделий декоративно-художественного и бытового назначения. The invention relates to the technology of silicates, namely to the production of glaze, which can be used for coating tiles, ceramic products for decorative, artistic and domestic purposes.

Известна глазурь, включающая, мас. SiO2 52,9-53,5; Al2O3 10,8-11,2; B2O3 18,1-19,5; SrO 11,9-12,5; CaO 1,7-1,8; MgO 0,3-0,4; K2O 1,6-1,7; Na2O 1,9-2,0; Fe2O3 0,4-0,5; TiO2 0,1-0,2 [1]
Недостатком глазури является низкая термостойкость 10 теплосмен.Known glaze, including, by weight. SiO 2 52.9-53.5; Al 2 O 3 10.8-11.2; B 2 O 3 18.1-19.5; SrO 11.9-12.5; CaO 1.7-1.8; MgO 0.3-0.4; K 2 O 1.6-1.7; Na 2 O 1.9-2.0; Fe 2 O 3 0.4-0.5; TiO 2 0.1-0.2 [1]
The disadvantage of glaze is low heat resistance 10 heat exchange.

Наиболее близкой к изобретению является глазурь, включающая, мас. SiO2 50,21-52,60; Al2O3 7,50-7,96; B2O3 12,07-12,66; SrO 11,27-11,81; CaO 1,87-1,92; K2O 0,31-0,38; Na2O 11,86-12,43; MgO 0,21-0,25; TiO2 0,10-4,57 [2]
Недостатком глазури является низкая термостойкость 5-7 теплосмен.Closest to the invention is the glaze, including, by weight. SiO 2 50.21-52.60; Al 2 O 3 7.50-7.96; B 2 O 3 12.07-12.66; SrO 11.27-11.81; CaO 1.87-1.92; K 2 O 0.31-0.38; Na 2 O 11.86-12.43; MgO 0.21-0.25; TiO 2 0.10-4.57 [2]
The disadvantage of glaze is the low heat resistance of 5-7 heat exchange.

Техническим результатом является повышение термостойкости. The technical result is an increase in heat resistance.

Это достигается тем, что глазурь включает следующие компоненты, мас. SiO2 52,0-54,0; Al2O3 3,5-5,6; CaO 13,5-16,0; MgO 1,0-3,0; Na2O 0,1-0,2; K2O 6,0-7,0; B2O3 10,9-11,9; SrO 2,0-4,0; TiO2 4,0-6,0.This is achieved by the fact that the glaze includes the following components, wt. SiO 2 52.0-54.0; Al 2 O 3 3.5-5.6; CaO 13.5-16.0; MgO 1.0-3.0; Na 2 O 0.1-0.2; K 2 O 6.0-7.0; B 2 O 3 10.9-11.9; SrO 2.0-4.0; TiO 2 4.0-6.0.

В таблице приведены составы глазури. The table shows the glaze compositions.

Глазурь готовят по следующей технологии. Glaze is prepared according to the following technology.

Взвешенные в указанных соотношениях компоненты варят при температуре 1400оС, фритту гранулируют и подвергают мокрому помолу. Суспензию наносят на керамические изделия и обжигают при 900оС.Weighed components in the indicated ratios is cooked at a temperature of 1400 ° C, and granulated frit is wet-milled. The suspension is applied to ceramic products and fired at 900 about C.
