FRIT FOR SINGLE LAYER ENAMEL COATING

摘要

FIELD: manufacturing of glass-enamel coating for steel cases of household gas and electrical equipment. ^ SUBSTANCE: claimed frit contains (mass %): SiO2 30.0-31.2; Al2O3 2.8-3.2; B2O3 14.0-15.0; CaO 0.5-0.6; TiO2 16.2-17.2; P2O5 1.5-1.9; Na2O 17.0-17.4; Li2O 8.0-8.8; K2O 6.0-8.0; MnO2 0.03-0.07; NiO 0.07-0.08; Fe2O2 0.06-0.08; CaF 0.1-0.2. Frit has melting point of 700-7800C. ^ EFFECT: light single layer enamel with minimum content of coloring oxides and lowered melting point. ^ 3 ex
