DIRECT-ON ENAMEL GLASS OF BROWN COLOR

摘要

The invention relates to chemical industry, namely to compositions of enamel glass frits for the process of powder electrostatic enameling parts from thin sheet low-carbon steel. A direct-on enamel glass of brown color contains, wt. %: (NaO+KO) 13.00-14.00; (BaO+CaO) 2.00-8.00; BO13.00-18.00; SiO50.00-52.50; (FeO+MnO+CoO+CuO) 8.0-14.0; CaF3.50-4.50; ZrO0.01-2.50. The synthesized enamel glass frit has boiling temperature of 1250 °C and burning temperature of 800-840 °C, chemical resistance of enamel coatings of class A, cohesive resistance with thin sheet low-carbon steels – 4-5 points.
