Formula of graphite enamel glaze and production process of graphite enamel glaze

Abstract

The invention discloses a graphite enamel glaze and a production process of the graphite enamel glaze. Si3N4 is added in the graphite enamel glaze, so that the expansion coefficient of the enamel can be adjusted and the adhesive force of the enamel and the graphite can be enhanced; Pr(No3)3.6H2O can enhance the dyeing power of the graphite enamel glaze; and enamel is enameled on the graphite product, so the graphite can be protected from being oxidized greatly, the service life of the graphite product is prolonged, strength of the graphite product is improved, the graphite product is easy to clean and the like, toxic substances penetrated into food are reduced, the application field of the graphite product is improved, and oneness of the appearance of the product is improved. The oxidation probability of the graphite can be reduced; the permeation probability of harmful substances in the graphite coating product can be reduced; the introduction of the graphite enamel glaze does not influence the advantages, such as the original thermal conductivity, the plasticity, high temperature resistance and the like, of the graphite; the enamel product is safe, non-toxic and easy to wash and clean and can be widely used as eating appliances and washing appliances in daily life; and under the specific condition, the glaze is enameled on the graphite body, the advantages and characteristics of high hardness, high temperature resistance, wear resistance, insulation effect and the like can be represented, so that the enamel product has wide application.

Description

technical field [0001] The invention relates to a graphite enamel glaze and a production process thereof. Background technique [0002] Graphite has the characteristics of good chemical stability, corrosion resistance, good thermal conductivity, and low permeability, and is widely used in the production of heat exchangers, heating containers, etc. However, graphite products have defects such as easy to oxidize, easy to stain, easy to scratch, and monotonous color. At present, some graphite products are coated with graphite products. First, it is easy to scratch during use. Graphite is not the same as it is easy to fall off, and the third is that the harmful components in the paint are easy to release during the heating process; while traditional enamel products are bulky, slow heat transfer, cannot be used in microwave ovens, the cost is high, and it is not economically cost-effective. Contents of the invention [0003] The purpose of the present invention is to provide a...
