Abstract

The invention provides a gas appliance burner cap surface enameling process. The gas appliance burner cap surface enameling process comprises the following steps that S1, glaze is prepared from the following raw materials: nickel oxide, alumina, cobalt oxide, sodium oxide, borax, sodium nitrite, clay, quartz powder, cobalt black, nickel and water; S2, mixing and ball-milling the raw materials to obtain glaze slip; S3, sanding the surface of a burner cap blank; S4, neutralizing and washing the surface of the burner cap blank; and S5, spraying the glaze slip obtained in the step S2 on the surface of the burner cap, and then drying, sintering and cooling. Through combination of the glaze formula and the process, a marble ceramic tile with excellent simulation degree is obtained. According tothe gas appliance burner cap surface enameling process, glaze slip raw materials are selected and optimized, and an improved enamel process is matched, so that the problem that the surface of a combustion stove is likely to corrode and rust is solved, the surface film thickness of the burner cap of the combustion stove is uniform and compact, the burner cap is more attractive, the environment is not polluted in the combustion process, and the problems of coating shedding and the like in the combustion process are solved.

Description

technical field [0001] The invention belongs to the field of surface enamel of metal products, and in particular relates to a surface enamel process of a fire cover of a burning appliance. Background technique [0002] Enamel, also known as enamel, is a composite material in which inorganic vitreous materials are condensed on the base metal by melting and firmly combined with the metal. Enamel is an inorganic glass enamel coated and fired on the surface of a metal base. Enamel coating on the metal surface can prevent the metal from rusting, so that the metal will not form an oxide layer on the surface when it is heated and can resist the erosion of various liquids. Enamel exhibits excellent properties such as high hardness, high temperature resistance, wear resistance and insulation on the metal body, making enamel products more widely used. The enamel coating can react with the metal matrix during the sintering process to form a chemical bond at the interface. Diffusion ...
