Description
Изобретение относитс к составу эмали, предназначенной дл защиты стали от воздействи гор чего щелочного раствора.This invention relates to an enamel composition designed to protect steel from the effects of hot alkaline solution.
Известен состав эмали, включающий SiO2, ВгОз, АЬОз, СаО, MgO, NajO.The known composition of the enamel, including SiO2, VgOz, Aloz, CaO, MgO, NajO.
Цель изобретени - повысить щелочестойкость эмали.The purpose of the invention is to increase the alkali resistance of enamel.
Это достигаетс тем, что эмаль содержит указанные компоненты в следующих количествах (в вес. %):This is achieved in that the enamel contains these components in the following amounts (in wt.%):
SiO250-60SiO250-60
ВгОз15-25VgOz15-25
АЬОз2-6ABOz2-6
СаО3-6CaO3-6
MgO1-5MgO1-5
ЫагО10-20YagO10-20
и кроме того, сверх 100% цирконат редкоземельных элементов, напримерand besides, in excess of 100% zirconate rare earth elements, for example
Pr2Zr2O70,5-10.Pr2Zr2O70,5-10.
фритту с добавкой сверх 100% глины 5% и 50% воды загружают в фарфоровый барабан дл размола и получени водного щликера .A frit with the addition of 5% clay and 50% water in excess of 100% is loaded into a porcelain drum to grind and produce an aqueous slick.
Эмалевый щликер нанос т на защищаемые детали напылением, высущивают и обжигаютThe enamel slip is sprayed onto the parts to be protected, dried and burned.
при температуре 850°С в течение 5-15 мин, в зависимости от размера детали.at a temperature of 850 ° C for 5-15 minutes, depending on the size of the part.
Описываема эмаль обладает высокойThe enamel described has a high
стойкостью к щелочным гор чим растворам иresistance to alkaline hot solutions and
5 хорощими технологическими свойствами5 good technological properties
(сцеплением с грунтом, сплощностью и т. д.).(adhesion with ground, flatness, etc.).
При испытании покрыти в гор чем растворе 1 Н. NaOH+1 п. Ыа2СОз в течение длительного времени потер веса покрыти из 0 описываемой эмали составл ла 2,5 мг/см-.When testing the coating in a hot solution of 1 N. NaOH + 1 p. Na2CO3 for a long time, the weight loss of the coating from 0 of the described enamel was 2.5 mg / cm.
