Description
Изобретение относитс к технике эмалировани стальной химической аппаратуры.This invention relates to a technique for enameling steel chemical apparatus.
Известна эмаль, включающа SiO2, АЬОз, СаО, NaaO, LiaO, CaFa.Enamel is known, including SiO2, ABO3, CaO, NaaO, LiaO, CaFa.
С целью расширени интервала обжига, повышени механической прочности, кислоте- и термостойкости, она содержит следующие компоненты, в вес. %:In order to extend the firing range, increase mechanical strength, acid and heat resistance, it contains the following components, in weight. %:
