Description
Изобретение относитс к области эмалировани металлов, а именно к созданию эмалей, широко примен емых дл получени защитных и декоратив-ных покрытий во многих област х про мышленности, в том числе в архитек туре и строительстве, судостроении, электробытовом машиностроении и др. Известен состав эмали, содержащий , вес.%: TiOa 11-13;Р205 3-5; 3-5; 15-20; S i О 3041; «20 3-8; Noi,.,0 5-10 ij . Недостатком этого состава вл етс низка химическа устойчивость покрыти и повышенна температура об жига. Наиболее близким вл етс состав эмали, содержащий, вес,%: StO 39,5-41,3; 1.3-2,0; BgOa 1820; NQgO 9,8-10,2; KgO 1,8-2,2; MgO 0,6-0,9; TiOo 15,6-17;p205 1Л-1,5;МазАЕРй 2,5-4,5; Zr-o 4-6 12, Недостатком этого состава вл етс повышенна температура обжига. Целью изобретени вл етс снижение температуры обжига. Она достигаетс тем, что эмаль, содержаща 5«02 Т Оа , , , .B OiKg О ,Na2.0,Mga дополнительно содержи , при следующем соотношении онентов зес 5iO,j. 7,5-15 TiOj, 15-17,5 22,5-30 10-12,5 10-15 0,5-3 12,5-15 0,5-3 0,5-3. же приведены составы эмали, сощие , вес,% : л приготовлени эмалевого шлиберут , вес.ч; фритта 100; глилуховской 3; воды 47. В качестаправочного средства примен рт щенный раствор поташа.The invention relates to the field of metal enameling, namely to the creation of enamels, widely used to produce protective and decorative coatings in many areas of industry, including architecture and construction, shipbuilding, electrical engineering, etc. containing, wt%: TiOa 11-13; P205 3-5; 3-5; 15-20; S i O 3041; “20 3-8; Noi., 0 5-10 ij. The disadvantage of this composition is the low chemical resistance of the coating and the increased temperature of the calcining. The closest is the enamel composition containing, by weight,%: StO 39.5-41.3; 1.3-2.0; BgOa 1820; NQgO 9.8-10.2; KgO 1.8-2.2; MgO 0.6-0.9; TiOo 15.6-17; p205 1L-1.5; MazAER 2.5-4.5; Zr-o 4-6 12, The disadvantage of this composition is an increased calcining temperature. The aim of the invention is to reduce the burning temperature. It is achieved by the fact that enamel containing 5 "02 T Oa,,, .B OiKg O, Na2.0, Mga is additionally contained, in the following ratio of onents 5es O, j. 7.5-15 TiOj, 15-17.5 22.5-30 10-12.5 10-15 0.5-3-3.5.5-15 0.5-3 0.5-3. The compositions of enamel are also given, sotsie, wt.%: l of preparation of enamel shear, weight.h; frit 100; Hlilukhov 3; 47. As a quality-applying agent, use a puppy solution of potash.
Эмали нанос т на загрунтованные стальные пластинки, методом окунани . Обжиг покрыти провод т в муфельной печи в течение 10 мин. Образцы обжц631478Enamels are applied to primed steel plates by dipping. Roasting of the coating is carried out in a muffle furnace for 10 minutes. Samples obzts631478
гают при температуре от 720 до .с интервалом обжига через 20с.They are heated at a temperature of from 720 to. With a firing interval of 20 s.
Описьоваемые составы обладают следукадими свойствами (см. таблицу).The compositions described have posledible properties (see table).
