Варку фритты эмали осуществляют при температуре ~ 1500°С. Расплав гранулируют в воду. Гранулы размалывают мокрым способом до прохождения через сетку 0056. Полученный порошок напыляют в струе плазмы на подготовленную поверхность изделий.Enamel frit is cooked at a temperature of ~ 1500 ° C. The melt is granulated into water. The granules are milled wet until passing through a mesh 0056. The resulting powder is sprayed in a plasma jet on the prepared surface of the products.

Химическая стойкость предложенной эмали к кислотам (потери в весе в 3% растворе HNO3) составит ~3% для всех составов.The chemical resistance of the proposed enamel to acids (weight loss in a 3% HNO 3 solution) will be ~ 3% for all formulations.
