Description

Изобретение относится к производству эмалей, которые могут быть использованы для покрытия изделий из чугуна и стали, в частности деталей оборудования пищевой, химической, нефтяной промышленности.The invention relates to the production of enamels that can be used to coat products from iron and steel, in particular parts of equipment for the food, chemical, and petroleum industries.

Известна эмаль, содержащая, мас. %: SiO2 58,05-58,83; Na2O 15,16-15,41; B2O3 9,85-10,18; Al2O3 5,36-5,53; СаО 4,97-6,09; MgO 1,24-1,42; K2O 1,4-1,62; MnO 0,44-0,47; СоО 0,3-0,31; ВаО 1,77-2,03; NiO 0,3-0,31 [1].Known enamel containing, by weight. %: SiO 2 58.05-58.83; Na 2 O 15.16-15.41; B 2 O 3 9.85-10.18; Al 2 O 3 5.36-5.53; CaO 4.97-6.09; MgO 1.24-1.42; K 2 O 1.4-1.62; MnO 0.44-0.47; CoO 0.3-0.31; BaO 1.77-2.03; NiO 0.3-0.31 [1].

Задачей изобретения является повышение кислотостойкости эмали.The objective of the invention is to increase the acid resistance of enamel.

Технический результат достигается тем, что эмаль, включающая SiO2, Na2O, B2O3, Al2O3, СаО, MgO, СоО, NiO, дополнительно содержит ZrO2 и Nd2O3 при следующем соотношении компонентов, мас. %: SiO2 58,0-61,0; Na2O 4,0-5,0; B2O3 9,8-10,6; Al2O3 13,0-15,0; СаО 3,2-4,0; MgO 1,0-2,0; СоО 0,1-0,2; NiO 0,1-0,3; ZrO2 5,5-6,2; Nd2O3 0,2-0,4.The technical result is achieved in that the enamel, including SiO 2 , Na 2 O, B 2 O 3 , Al 2 O 3 , CaO, MgO, CoO, NiO, additionally contains ZrO 2 and Nd 2 O 3 in the following ratio of components, wt. %: SiO 2 58.0-61.0; Na 2 O 4.0-5.0; B 2 O 3 9.8-10.6; Al 2 O 3 13.0-15.0; CaO 3.2-4.0; MgO 1.0-2.0; CoO 0.1-0.2; NiO 0.1-0.3; ZrO 2 5.5-6.2; Nd 2 O 3 0.2-0.4.

В таблице приведены составы эмали.The table shows the composition of the enamel.

Варку фритты эмали осуществляют при температуре 1430-1470°С. Расплав гранулируют в воду. Гранулы размалывают мокрым способом до прохождения через сетку 0056. Полученный шликер с влажностью 44-50% наносят (напыляют) на подготовленную поверхность изделий и закрепляют оплавлением.Enamel frit is cooked at a temperature of 1430-1470 ° C. The melt is granulated into water. The granules are milled wet until passing through a mesh 0056. The resulting slurry with a moisture content of 44-50% is applied (sprayed) to the prepared surface of the products and fixed by reflow.
