Abstract
This paper presents the results of developing a direct-on enamel frit that exhibits increased chemical resistance against acid and alkali environments, intended for protection of steel pipelines. Zinc oxide was introduced into the frit composition, which improved the resistance of the material due to the higher energy of the metal ion–oxygen chemical bond compared to alkali metal ions. At the same time, the addition of ZnO in the amount of 10 wt.% reduces the flow temperature of the frit. The developed frit composition meets the standard requirements in terms of spreading capacity (45 mm) and thermal coefficient of linear expansion (112 × 10 –7K–1 ). The introduction of zinc oxide in industrial borosilicate enamel in the amount of 5 wt.% leads to an increase in its chemical resistance against acids and alkalis by 4 and 8 times, respectively, compared to conventional industrial frit.
