Heat-resistant ceramic pot and preparation method thereof

Abstract

The invention relates to a heat-resistant ceramic pot which is composed of the following components in parts by weight: 65-80 parts of spodumene, 13-20 parts of clay, 10-16 parts of kaolin, 8-13 parts of sandstorm soil, 6-11 parts of dickite, 5-9 parts of pyrauxite, 2-7 parts of obsidian and 0-0.5 part of zoisite. The preparation method of the heat-resistant ceramic pot comprises the following steps: S1. manufacturing of billet: mixing the raw materials according to parts by weight, pugging, carrying out injection forming, trimming the billet, sending the billet into a kiln, and carrying out bisque firing to prepare a biscuit; S2. treatment of biscuit internal surface: spraying a non-stick paint on the biscuit internal surface, and baking; and S3. treatment of biscuit external surface: spraying a ceramic paint on the biscuit external surface twice, spraying a metal coating, spraying silicone oil, and finally, spraying the non-stick paint. The heat-resistant ceramic pot product has greatly enhanced high-temperature capability, can directly contact the electromagnetic oven, has the advantages of high heat transfer rate and obvious energy saving effect, and can bear the high power of the electromagnetic oven of up to 2100W.

Description

technical field [0001] The invention relates to the technical field of daily-use ceramics, in particular to a heat-resistant ceramic pot and a preparation method thereof. Background technique [0002] Induction cooker is deeply loved by consumers because of its fast heating up, controllable temperature, high thermal efficiency, no open flame, and no harmful gas generation. The induction cooker works according to the principle of electromagnetic induction. When using it, it is required that the pan used with the induction cooker must be able to conduct magnetism. Ordinary ceramic pots and pans are non-magnetic and cannot be used on induction cookers. In order to solve this problem, the more commonly used method at present is to bond a layer of metal magnetic film on the bottom of the ceramic pot, but the ceramic pot prepared by this method is slow in heat conduction and magnetic conduction, and there are defects that cannot be used on open flames. Defects, and the metal mag...

AI Technical Summary

Problems solved by technology

Ordinary ceramic pots and pans are non-magnetic and cannot be used on induction cookers.

In order to solve this problem, the more commonly used method at present is to bond a layer of metal magnetic film on the bottom of the ceramic pot, but the ceramic pot prepared by this method is slow in heat conduction and magnetic conduction, and there are defects that cannot be used on open flames. Defects, and the metal magnetic film is easy to wear and fail

In addition, when the power of the induction cooker is greater than 1200W, ordinary ceramic pots are prone to bursting due to excessive heat, and the service life is only about 6 months
