Problems solved by technology

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 coating are easy to release during the heating process; while traditional enamel products are bulky, slow heat transfer, cannot be used in microwave ovens, and are expensive and economically uneconomical.

Embodiment

[0013] Graphite enamel glaze formula consists of the following components by weight percentage:

[0014] SiO 2 45%, K 2 O4.5%, B 2 o 3 15%, MnO 2 5.5%, Na 2 O12%, Fe 2 o 3 5%, CaO 2%, CoO 0.6%, NiO 2%, TiO 2 0.6%, Si 3 N 4 0.6%, Pr(No 3 ) 3 ·6H 2 O 0.6%, clay 5%, borax 0.2%, nitrous 0.3%, nickelous oxide 0.6%, selenium powder 0.5%.

[0015] Production process of graphite enamel enamel:

[0016] 1), the SiO 2 、K 2 O.B 2 o 3 , MnO 2 、Na 2 O, Fe 2 o 3 , CaO, CoO, NiO, TiO2, Si 3 N 4 、Pr(No 3 ) 3 ·6H 2 The O component is mixed evenly in proportion, calcined and melted at a temperature of 1000-15000 °C, and then poured into cold water for continuous stirring;

[0017] 2) After cooling, it is crushed to 80-140 meshes by a pulverizer, and clay, borax, nitrous, nickelous oxide, and selenium powder are added to ball mill together to make graphite enamel enamel.

[0018] A kind of production method of graphite enamel product:

[0019] 1), the graphite heat ...

Abstract

The invention discloses a production method of a graphite enameled product. A graphite product is enameled, thus graphite can be greatly prevented from being oxidized, the service life and strength of the graphite product are enhanced, the graphite product is easy to clean, the toxic substances in the graphite product are prevented from penetrating into foods, the application field of the graphite product is broadened, and the single appearance of the product is improved, and the like. According to the invention, the oxidation of graphite and the penetration of harmful substances in the graphite coating product are lowered; the graphite product is enameled, which dose not influence the original thermal conductivity, plasticity and high temperature resistance of the graphite; by combining with the characteristics that an enameled product is safe and toxic and is easy to wash and clean, the graphite enameled product can be widely used as a food and drink vessel and a washing vessel which are used in daily life; and under the special conditions, the ceramic glaze is enameled on a graphite green body, so the enameled product exhibits good properties such as high hardness, high temperature resistance, wear resistance, good insulation and the like, thereby ensuring the wider application of the enameled product.

Description

technical field [0001] The invention relates to a production process of graphite enamel products. 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 product...
