Description

Изобретение относитс  к составу эмали, предназначенной дл  защиты черных металлов от коррозии.This invention relates to an enamel composition designed to protect ferrous metals from corrosion.

Известна кислотостойка  эмаль, включающа  SiOg, АЬОз, NagO, K,zO, LigO, ВгОз, Сг20з, одно соединение из группы фторидов СаРг, NaaSiFs, NasAlFg, CaO.Known acid-resistant enamel, including SiOg, ABOz, NagO, K, zO, LigO, BrOz, Cr20z, one compound from the group of fluorides, SaRg, NaaSiFs, NasAlFg, CaO.

Цель изобретени -увеличение кислотостойкости эмали при повышенных температурах. Достигаетс  это тем, что она дополнительно содержит SrO, TiOa, ZrOz при следующем соотношении компонентов в вес. %:The purpose of the invention is to increase the acid resistance of enamel at elevated temperatures. This is achieved in that it additionally contains SrO, TiOa, ZrOz in the following ratio of components by weight. %:

SiOa 65--75; АЬОз 0,5-4; NagO 2-8,2; К2О 0,1 - 1,8; ЫгО 1,5-9; В2Оз 0,1-4; СггОз 0,1-4, одно соединение из группы фторидов СаРз, NazSiFe, NasAlFe 0,1-3; CaO+SrO 2-11; ТЮг 0,1-5; ZrOg 0,1-5.SiOa 65--75; ABOZ 0.5-4; NagO 2-8,2; K2O 0.1 - 1.8; YHO 1.5-9; B2O3 0.1-4; CrGOz 0.1-4, one compound from the group of fluorides CaP3, NazSiFe, NasAlFe 0.1-3; CaO + SrO 2-11; South 0.1-5; ZrOg 0.1-5.
