Description

Изобретение относится к составам керамических масс, используемых в производстве фасадной плитки.The invention relates to compositions of ceramic masses used in the manufacture of facade tiles.

Известна керамическая масса следующего состава, мас.%: глина огнеупорная 50,0-80,0; доменный шлак 20,0-50,0 [1].Known ceramic mass of the following composition, wt.%: Refractory clay 50.0-80.0; blast furnace slag 20.0-50.0 [1].

Задача изобретения - снижение температуры обжига изделий, полученных из керамической массы.The objective of the invention is to reduce the firing temperature of products obtained from ceramic mass.

Технический результат достигается тем, что керамическая масса, включающая глину, доменный шлак, дополнительно содержит фосфорит и волластонит при следующем соотношении компонентов, мас.%: глина кирпичная 83,0-84,0; доменный шлак 6,0-7,0; фосфорит 6,0-7,0; волластонит 3,0-4,0.The technical result is achieved in that the ceramic mass, including clay, blast furnace slag, additionally contains phosphorite and wollastonite in the following ratio of components, wt.%: Brick clay 83.0-84.0; blast furnace slag 6.0-7.0; phosphorite 6.0-7.0; wollastonite 3.0-4.0.

В таблице приведены составы керамической массы.The table shows the composition of the ceramic mass.

В составе керамической массы может быть использована глина кирпичная любых месторождений, например глина Мало-Ступкинского месторождения, характеризующаяся следующим химическим составом, мас.%: SiO2 52,0-75,1; Al2O3 12,67-21,94; Fe2O3 2,7-6,44; CaO 1,76-7,07; MgO 1,08-5,42; SO3 0,87; п.п.п. 3,01-4,2.In the composition of the ceramic mass, clay clay of any deposits can be used, for example, clay of the Malo-Stupkinskoye deposit, characterized by the following chemical composition, wt.%: SiO 2 52.0-75.1; Al 2 O 3 12.67-21.94; Fe 2 O 3 2.7-6.44; CaO 1.76-7.07; MgO 1.08-5.42; SO 3 0.87; p.p.p. 3.01-4.2.

Доменный шлак характеризуется следующим химическим составом, мас.%: SiO2 36,0-41,0; Al2O3 8,0-11,0; FeO 0,2-0,7; CaO 40,0-48,0; MgO 6,0-10,0; MnO 0,1-1,0; SO3 0,5-2,2. Фосфорит - осадочная горная порода, состоящая из тонкозернистой смеси апатита с примесью кварца, карбоната, глинистых частиц и др. Волластонит - минерал, метасиликат кальция, содержащий, мас.%: SiO2 51,75; CaO 48,25.Blast furnace slag is characterized by the following chemical composition, in weight%: SiO 2 36,0-41,0;. Al 2 O 3 8.0-11.0; FeO 0.2-0.7; CaO 40.0-48.0; MgO 6.0-10.0; MnO 0.1-1.0; SO 3 0.5-2.2. Phosphorite is a sedimentary rock consisting of a fine-grained mixture of apatite with an admixture of quartz, carbonate, clay particles, etc. Wollastonite is a mineral, calcium metasilicate, containing, wt.%: SiO 2 51.75; CaO 48.25.

Компоненты дозируют в требуемых количествах, по отдельности размалывают до прохождения через сито №0,14, смешивают и готовят керамическую массу с влажностью 18-22%. Из полученной керамической массы пластическим способом формуют плитку, которую сушат и обжигают при температуре 950-970°C. Поверхность плитки оплавляют низкотемпературной плазмой до образования на ней стекловидного слоя.The components are dosed in the required quantities, individually grinded before passing through a No. 0.14 sieve, mixed and a ceramic mass is prepared with a moisture content of 18-22%. From the obtained ceramic mass, a tile is molded in a plastic way, which is dried and fired at a temperature of 950-970 ° C. The surface of the tile is fused with low-temperature plasma until a glassy layer forms on it.
