Описываема эмаль плавитс при температуре 1330-1350°С. Изготовление шликера осуществл етс общеприн тым методом с применением в качестве добавок глины, буры и др. Покрытие обжигаетс при температуре 840- 850°С. Дл повыщени химической устойчивости в качестве мельничных добавок добавл ют в щликер SiO2 или ZrSi04 в количестве 20% от веса сухого эмалевого порошка. Н.нже нривод тс свойства эмали. Потери веса в % после 4-часовой обработки:The enamel described is melted at a temperature of 1330-1350 ° C. The manufacture of a slip is carried out by a conventional method using clay, borax, etc. as additives. The coating is burned at a temperature of 840-850 ° C. To increase chemical stability, as a mill additive, SiO2 or ZrSi04 is added to the slurry in the amount of 20% by weight of dry enamel powder. The properties of enamel are generally lower.
