Abstract
Description
Изобретение относится к технологии силикатов и касается составов глазурей для нанесения на керамическую плитку.The invention relates to the technology of silicates and relates to compositions of glazes for application to ceramic tiles.
Известна глазурь, включающая, мас. %: SiO2 40,42-44,16; Al2O3 9,84-10,64; CaO 23,82-26,93; MgO 17,09-18,91; Na2O 2,02-2,22; К2О 1,58-1,73; Fe2O3 0,3-0,32 [1]. Термостойкость глазури составляет 9-11 теплосмен.Known glaze, including, by weight. %: SiO 2 40.42-44.16; Al 2 O 3 9.84-10.64; CaO 23.82-26.93; MgO 17.09-18.91; Na 2 O 2.02-2.22; K 2 O 1.58-1.73; Fe 2 O 3 0.3-0.32 [1]. The temperature resistance of the glaze is 9-11 heat exchange.
Известна также глазурь, содержащая, мас. %: SiO2 30,0-35,0; Al2O3 2,0-7,0; В2О3 18,0-30,0; Na2O 4,0-8,0; СеО2 4,0-12,0; пара оксидов из группы ВаО 15,0-25,0; SrO 15,0-20,0; CaO 10,0-17,0; MgO 1,0-8,0 [2]. Термостойкость глазури составляет 10-12 теплосмен.Glaze is also known, containing, by weight. %: SiO 2 30.0-35.0; Al 2 O 3 2.0-7.0; B 2 O 3 18.0-30.0; Na 2 O 4.0-8.0; CeO 2 4.0-12.0; a pair of oxides from the group BaO 15.0-25.0; SrO 15.0-20.0; CaO 10.0-17.0; MgO 1.0-8.0 [2]. The temperature resistance of the glaze is 10-12 heat cycles.
Задача изобретения состоит в повышении термостойкости глазури.The objective of the invention is to increase the heat resistance of the glaze.
Технический результат достигается тем, что в составе глазури, содержащей SiO2, Al2O3, Na2O, СеО2, ВаО, CaO, MgO, компоненты находятся при следующем соотношении, мас. %.: SiO2 30,0-35,0; Al2O3 23,0-28,0; В2О3 6,0-8,0; Na2O 4,0-8,0; СеО2 8,0-12,0; ВаО 2,0-4,0; CaO 4,0-6,0; MgO 10,0-12,0.The technical result is achieved by the fact that in the composition of the glaze containing SiO 2 , Al 2 O 3 , Na 2 O, CeO 2 , BaO, CaO, MgO, the components are in the following ratio, wt. % .: SiO 2 30.0-35.0; Al 2 O 3 23.0-28.0; B 2 O 3 6.0-8.0; Na 2 O 4.0-8.0; CeO 2 8.0-12.0; BaO 2.0-4.0; CaO 4.0-6.0; MgO 10.0-12.0.
В таблице приведены составы глазури.The table shows the glaze compositions.
Варку фритты осуществляют в электропечи при температуре 1400°С. Расплав гранулируют в воду и измельчают до полного прохождения через сетку №0056. Подготавливают глазурную суспензию с влажностью 45-47%.The frits are cooked in an electric furnace at a temperature of 1400 ° C. The melt is granulated into water and ground until it passes through mesh No. 0056. Prepare a glaze suspension with a moisture content of 45-47%.
Готовую глазурную суспензию наносят (напылением, поливом) на поверхность керамической плитки, сушат на воздухе и обжигают в электропечи при температуре 1050°С в течение 30-45 мин.The finished glaze suspension is applied (by spraying, watering) on the surface of a ceramic tile, dried in air and fired in an electric furnace at a temperature of 1050 ° C for 30-45 minutes.
