Problems solved by technology

[0002] The traditional molding method of microwave oven or oven cavity is mostly spraying enamel coating or Teflon coating on the surface of the alloy cavity. However, the enamel coating must be baked at a high temperature above 800°C, and the cavity is easily caused by thermal expansion and contraction. Body deformation and use of huge energy consumption, while the heat-resistant temperature of Teflon coating is about 250 ℃, it can decompose toxic fluorine-containing gas under high temperature environment, which will cause great harm to human health, so in order to improve the above defects , it is necessary to continuously improve the molding method of the cavity

Embodiment Construction

[0018] A method for forming a cavity of a microwave oven or an oven, comprising the following steps:

[0019] (1) Prepare sheet: select and prepare sheet according to the thickness of molding cavity, described sheet is common iron plate, aluminized plate or cold-rolled plate;

[0020] (2) Firstly carry out sand blasting treatment to the surface, the pressure of the sand blasting treatment is 0.7MPa, the sand material particle size is 60-120 mesh, and then clean and package into sheets or coils;

[0021] (3) Cut the sheet or coil, bend it, and weld it after shallow stretching;

[0022] (4) After degreasing, cleaning and drying, ceramic coating is sprayed, heated and solidified, and the curing temperature is 280°C. The ceramic coating is composed of the following raw materials in parts by weight:

[0023] Silicon carbide 3, tetraethyl orthosilicate 100, boron nitride 30, inorganic toner 12, polyacrylamide 0.5, silane coupling agent Kh560 0.7, isopropyl tris(dioctyl pyrophosphat...

Abstract

The invention discloses a forming method for a microwave oven cavity or an oven cavity. The forming method comprises the following steps of preparing sheet materials; performing surface treatment on the sheet materials; performing welding and shaping, and powder ceramic coating spraying. According to the forming method, the rough sand finish surfaces of the sheet materials are prepared firstly; then a welding and forming way is adopted, and next, the ceramic coating is sprayed, so that it is ensured that the cavity is not deformed, and the ceramic coating which is low in energy consumption, high in strength, resistant to high temperature, non-viscous and easy to clean can be obtained; the sheet materials are subjected to sand blasting treatment firstly and then the powder ceramic coating is sprayed, so that the conditions of high energy consumption, high-temperature solidification and deformation, or toxic fluorine-containing gas decomposition at a high temperature of the conventional enamel coating or Teflon coating can be avoided; and in addition, the cavity forming method disclosed by the invention achieves the beneficial effects of simple process, easy operation, high use safety, and strong high-temperature resistance.

technical field [0001] The invention belongs to the field of cavity processing, and specifically designs a method for forming a cavity of a microwave oven or an oven. Background technique [0002] The traditional molding method of microwave oven or oven cavity is mostly spraying enamel coating or Teflon coating on the surface of the alloy cavity. However, the enamel coating must be baked at a high temperature above 800°C, and the cavity is easily caused by thermal expansion and contraction. Body deformation and use of huge energy consumption, while the heat-resistant temperature of Teflon coating is about 250 ℃, it can decompose toxic fluorine-containing gas under high temperature environment, which will cause great harm to human health, so in order to improve the above defects , it is necessary to continuously improve the molding method of the cavity. Contents of the invention [0003] The object of the present invention is to provide a method for forming a cavity of a m...
