Description

Изобретение относится к технологии силикатов, в частности к составам эмалей, применяемых для получения защитного покрытия на металлических изделиях. The invention relates to the technology of silicates, in particular to compositions of enamels used to obtain a protective coating on metal products.

Известна эмаль, содержащая следующие компоненты, мас. % : SiO2 33,0-38,0; Al2O3 3,5-8,5; B2O3 15,5-18,0; Na2O 15,5-19,2; CаО 3,5-6,4; Cr2O3 0,5-2,7; P2O5 5,3-6,9; MgO 3,0-7,7; Fe2O3 0,2-3,5; ZnO 3,3-5,8 [1] . Растекаемость такой эмали составляет при 800оС 33-35 мм. Температура обжига эмали 780-820оС.Known enamel containing the following components, wt. %: SiO 2 33.0-38.0; Al 2 O 3 3.5-8.5; B 2 O 3 15.5-18.0; Na 2 O 15.5-19.2; CaO 3.5-6.4; Cr 2 O 3 0.5-2.7; P 2 O 5 5.3-6.9; MgO 3.0-7.7; Fe 2 O 3 0.2-3.5; ZnO 3.3-5.8 [1]. Spreadability is such enamel at 800 ° C of 33-35 mm. Enamel firing temperature 780-820 о С.

Цель изобретения - повышение растекаемости и снижение температуры обжига эмали. The purpose of the invention is to increase the flowability and lowering the temperature of enamel burning.

Цель достигается тем, что эмаль содержит следующие компоненты, мас. % : SiO2 31,0-32,0; Al2O3 3,9-4,5; В2О3 11,0-12,0; Na2O 17,2-18,0; CaO 5,8-6,5; Cr2O3 1,0-1,5; P2O5 5,9-6,9; MgO 4,3-5,3; Fe2O3 2,0-2,8; ZnO 6,4-7,1; PbO 6,8-8,0.The goal is achieved in that the enamel contains the following components, wt. %: SiO 2 31.0-32.0; Al 2 O 3 3.9-4.5; B 2 O 3 11.0-12.0; Na 2 O 17.2-18.0; CaO 5.8-6.5; Cr 2 O 3 1.0-1.5; P 2 O 5 5.9-6.9; MgO 4.3-5.3; Fe 2 O 3 2.0-2.8; ZnO 6.4-7.1; PbO 6.8-8.0.

В таблице приведены конкретные составы предложенной эмали. The table shows the specific compositions of the proposed enamel.

Растекаемость предложенной эмали при 760оС для 1 и 3 составов составляет 40 мм; для 2 состава - 43 мм.Spreadability proposed enamel at 760 ° C for formulations 1 and 3 is 40 mm; for 2 compositions - 43 mm.

Обжиг эмали может быть проведен при 750-770оС.Firing enamel can be carried out at 750-770 about C.
