Abstract

FIELD: chemistry.
SUBSTANCE: two layers of glaze suspension are applied successively, dried and burned. Before applying the lower layer of opacified glaze suspension, silicon carbide screened through sieve No 008 in amount of 0.5-5% of suspension weight is introduced in it. Initial softening temperature of the top layer of transparent glaze suspension is lower than softening temperature of the lower layer by 30-50°C. The lower glaze layer is applied by dipping or coating, the top layer is applied by spraying.
EFFECT: simplified technology for production of articles.

Description

Изобретение относится к производству керамических художественных изделий.The invention relates to the production of ceramic art products.

Известен способ получения декоративного глазурного покрытия на поверхности керамического изделия, включающий последовательное нанесение двух слоев глазурной суспензии, причем верхний слой глазурной суспензии, содержащий вызывающую его усадку добавку пластичной глины или гидрата глинозема, наносят на нижний слой после его сушки и обжига. Во время сушки и обжига верхнего слоя глазурной суспензии он дает усадку, вследствие чего трескается и разрывается [1].A known method for producing a decorative glaze coating on the surface of a ceramic product, comprising applying two layers of the glaze suspension in series, the upper layer of the glaze suspension containing the shrinkage additive adding plastic clay or alumina hydrate, is applied to the lower layer after drying and firing. During drying and firing of the upper layer of the glaze suspension, it shrinks, as a result of which it cracks and breaks [1].

Такая технология получения декоративного глазурного покрытия на поверхности керамического изделия требует двукратного обжига.Such a technology for producing a decorative glaze coating on the surface of a ceramic product requires double firing.

Задачей изобретения является упрощение способа получения декоративного глазурного покрытия на поверхности керамического изделия.The objective of the invention is to simplify the method of obtaining a decorative glaze coating on the surface of a ceramic product.

Технический результат достигается тем, что по способу получения декоративного глазурного покрытия на поверхности керамического изделия, включающему последовательное нанесение двух слоев глазурной суспензии, сушку, обжиг, перед нанесением нижнего слоя глушеной глазурной суспензий в нее вводят просеянный через сито №008 карбид кремния в количестве 0,5-5% от массы суспензии, причем температура начала размягчения верхнего слоя прозрачной глазурной суспензии на 30-50°С ниже температуры размягчения нижнего слоя. Нижний слой глазури наносят окунанием или поливом, а верхний - напылением.The technical result is achieved by the fact that according to the method for producing a decorative glaze coating on the surface of a ceramic product, including the sequential application of two layers of the glaze suspension, drying, firing, before applying the lower layer of the glazed glaze suspensions, silicon carbide sieved through a No. 008 sieve in the amount of 0, 5-5% by weight of the suspension, and the temperature of the onset of softening of the upper layer of a transparent glaze suspension is 30-50 ° C lower than the softening temperature of the lower layer. The lower layer of glaze is applied by dipping or watering, and the upper layer is sprayed.

Способ поясняется следующими примерами.The method is illustrated by the following examples.

1. Подготавливают глазурные суспензии с влажностью 43-50%, например глушеной глазури синего (температура начала размягчения 700°С) цвета и прозрачной бесцветной (температура начала размягчения 670°С) глазури. В глазурную суспензию синего цвета вводят просеянный через сито №008 карбид кремния в количестве 0,5% от ее массы. На поверхность керамического изделия (плитки) наносят (поливом) слой глазурной суспензии синего цвета, сушат, после чего наносят (напыляют) слой прозрачной глазурной суспензии. Затем осуществляют сушку и обжиг изделия при температуре 870°С. При обжиге за счет частичного разложения карбида кремния оба слоя глазури деформируются.1. Prepare glaze suspensions with a moisture content of 43-50%, for example, a glazed blue glaze (softening start temperature 700 ° C) and transparent colorless (670 ° C softening start temperature) glaze. Silicon carbide sieved through a No. 008 sieve is introduced into a blue glaze suspension in an amount of 0.5% of its mass. A layer of a blue glaze suspension is applied (by irrigation) to the surface of a ceramic product (tile), dried, and then a layer of a transparent glaze suspension is applied (sprayed). Then carry out the drying and firing of the product at a temperature of 870 ° C. During firing due to the partial decomposition of silicon carbide, both layers of the glaze are deformed.

2. Подготавливают глазурные суспензии с влажностью 43-50%, например глушеной глазури черного (температура начала размягчения 720°С) цвета и прозрачной зеленого цвета (температура начала размягчения 670°С) глазури. В глазурную суспензию черного цвета вводят просеянный через сито №008 карбид кремния в количестве 5% от ее массы. На поверхность керамического изделия (тарелки) наносят (окунанием) слой глазурной суспензии черного цвета, сушат, после чего наносят (напыляют) слой прозрачной зеленой глазурной суспензии. Затем осуществляют сушку и обжиг изделия при температуре 950°С. При обжиге за счет частичного разложения карбида кремния оба слоя глазури деформируются.2. Prepare glaze suspensions with a moisture content of 43-50%, for example, a black glaze of a black (softening start temperature of 720 ° C) color and a transparent green color (softening start temperature of 670 ° C) of the glaze. 5% of the mass of silicon carbide sieved through a No. 008 sieve is introduced into a black glaze suspension. A layer of black glaze suspension is applied (by dipping) to the surface of the ceramic product (plate), dried, and then a layer of transparent green glaze suspension is applied (sprayed). Then carry out the drying and firing of the product at a temperature of 950 ° C. During firing due to the partial decomposition of silicon carbide, both layers of the glaze are deformed.

Предложенный способ не сложен, предусматривает однократный обжиг керамических изделий.The proposed method is not complicated, provides for a single firing of ceramic products.
