Description
54) ЭМАЛЬ54) ENAMEL
Изобретение относитс к технике получени антикоррозионных цветных эмалевых покрытий на стальных издели х хоз йственно-бытового назначени , газовой апиаратуры и облицовочных плитках.The invention relates to a technique for producing anticorrosive colored enamel coatings on steel products for household purposes, gas aparature and tiles.
Известна покровна эмаль, содеожаща , Bec.%:Si02 7,8-57,6,.,2-15,8;Coating enamel is known, containing, Bec.%: Si02 7.8-57.6,., 2-15.8;
BgOj 5,О-6,4;Са.О O,5-O,6;MgU О,2-О,3; F 7,8-9,1;НаJi 15,6-21,6 1, Цветныепо крыти на их основе получают при добавке на помол фритт керамических пигментов н минеральных красителей при обжиге покрытий в интервале температур 820-86О°С.BgOj 5, O-6.4; Ca.O O, 5-O, 6; MgU O, 2-O, 3; F 7.8-9.1; NaJI 15.6-21.6 1; Colored coatings based on them are obtained by adding to the grinding of frits of ceramic pigments and mineral dyes during roasting of coatings in the temperature range of 820-86 ° C.
Известен состав эмали, включающийKnown composition of enamel, including
Si02,Na.O .B205,NG,jAeT6,CaO 2.Si02, Na.O .B205, NG, jAeT6, CaO 2.
Недостатком известных глазурей вл ет с низкий коэффициент термического расширени и высока температура начала разм гчени и обжига.A disadvantage of the known glazes is the low coefficient of thermal expansion and the high softening and firing temperature.
Цель изобретени - повышение коэффициента термического расширени и понижениеThe purpose of the invention is to increase the coefficient of thermal expansion and decrease
температуры качапа разм гчени , а та1Кже температуры обжига.softening temperature, and also calcining temperature.
Это достигаетс тем, что эмаль дополнительно содержит Мег О, In О, No С С при следующем соотношении компонентов, вес.%: SLOa 47,2-48,5; M,,2-4, 18,720 ,4;В.,0 13,6-14,2; fa5AfFg 9,8-11,1; СаО 0,6-0,9;Mg;D О,6-1.О;2пО 1,О-2Д; NaM 0,8-1,5.This is achieved by the fact that the enamel additionally contains Meg O, In O, and No C C in the following ratio of components, wt.%: SLOa 47.2-48.5; M ,, 2-4, 18,720, 4; V., 0 13.6-14.2; fa5AfFg 9.8-11.1; CaO 0.6-0.9; Mg; D O, 6-1.O; 2pO 1, O-2D; NaM 0.8-1.5.
Варку эмалей осуществл ют из технических сырьевых материалов в течение 45-6О мин при 12ОО-122О°С. Расплав гранулируют на воду. Помол фритт производ т мокрым способом с добавкой глины и пигментов . Шликер нанос т на загрунтованные издели и после сушки обжигают в интервале температур 7ОО-82ОС.The enamels are cooked from technical raw materials for 45-6 ° C at 12OO-122 ° C. The melt is granulated into water. The grinding of the frits is done wet with the addition of clay and pigments. The slip is applied to the primed products and, after drying, burned in the temperature range 7OO-82OC.
В таблице 1 приведены составы эмалей,Table 1 shows the compositions of enamels,
В таблице 2 приведены свойства эмалей и покрытий.Table 2 shows the properties of enamels and coatings.
Добавл на помол керс1мические пигменты , можно получать цветные покрыти .By adding kersemic pigments to the grinding, colored coatings can be obtained.
