  The present invention relates to an apparatus coating method and a coating apparatus using magnetic force, and more particularly to an apparatus coating method and a coating apparatus that allow unevenness to be formed on the surface of a kitchen appliance using magnetic force. .

  Common instruments that need to be coated on the surface are generally made of a metal such as aluminum. In the early days, the metal itself was used untreated, but during use, for example in the case of kitchen utensils, the surface of the utensils was damaged when cooking or otherwise. In order to prevent the problem of sticking and the like, an apparatus in which a coating liquid is applied to the surface and a coating layer is formed on the surface has been developed. With the development of various types of coating solutions, instruments with various types of coating layers formed on the surface have appeared.

  Usually, kitchen appliances have a coating layer that is heat-treated after a coating 10a made of a binder, a solvent, and a filler is applied to the surface.

  The coating layer is divided into a primer coat, a mid coat, and a top coat according to the order of coating and laminating on the kitchen utensil surface.

  That is, the primer coat refers to a coating layer to be coated on the surface of the kitchen appliance, the mid coat is coated on the primer coat and has a double coating layer together with the primer coat, and the top coat is It is coated on top of the midcoat and has a triple coating layer along with the primer coat and midcoat.

  Here, the kitchen appliance can be used by selecting each coating layer.
