Study on Preparation and Properties of Enamel Material

Abstract

Reference to the domestic and foreign relevant technical data, the paper design and manufacture enamel materials with a temperature resistant shock resistance and acid resistance excellent chemical stability, research on microscopic morphology of the enamel surface by scanning electron microscope, the experiment results showed: mill addition certain amount of zirconium silicate crystal in enamel material, enable enamel material to form composite materials of amorphous material and zirconium silicate crystals, it can effectively improve its temperature shock property; it is necessary to improve the enamel material temperature resistance shock property, but also maintain its excellent acid resistance, there is a optimal weight range mill addition into zirconium silicate crystal. I. INSTRUCTION Enamel is one or more layers of glass glaze that deep overbite in the metal surface, composite solid combination that metal and inorganic oxides firing at high temperature. Enamel coating is a kind of amorphous inorganic non- metallic materials, the surface is smooth, with good corrosion resistance. It has the strength of steel, extensibility and glass acid and alkali corrosion resistance, not easy to contaminate the products, easy cleaning and other advantages, it can give the material surface abrasion resistance, corrosion resistance, heat resistance, radiation resistance, and optical, electric, thermal, magnetic and other special performance, so as to improve the performance, extended to the service life. This paper systematically developed enamel formula, prepared enamel good acid resistance, and zirconium silicate crystal is introduced into the enamel by mill addition method, the preparation of composite enamel materials not only excellent acid resistance, and high temperature resistant blast performance is also very good, fully able to meet the requirements of desulfurization of heat exchanger heat exchange plate technology. The paper analyze the enamel materials uses scanning electron microscope morphology, and research on the effect of surface structure of the enamel materials on enamel material performance.
