A metallic apparatus that can promote thermal conduction and coating method

Abstract

The invention discloses a metallic apparatus that can promote thermal conduction and coating method, and in three layers of coating, coating liquor in the lower coating comprises NMP solution of polyamide, water, PTFE dispersion liquid, carbon black dispersion liquid, and earth silicon dispersion liquid; the coating liquor in the middle coating comprises PTFE dispersion liquid, water, aromatic hydrocarbon, triethylamine, oleate, surfactants, carbon black dispersion liquid and mica; spray coloring agent on each coating surface by a sprayer, wherein the coloring agent is added with finely divided metal of high thermoconductivity; coat the finely divided metal of the coating surface in uneven points, then go through heat treating, so that surface of the coating and the metal coating with coloring agent form concave-convex of irregular pattern.

Description

technical field [0001] The present invention relates to a utensil containing a metal that promotes heat conduction and a coating method thereof, and more particularly relates to a utensil containing a thermal conductivity catalyst and a coating method thereof, which is to selectively coat a metal powder with high thermal conductivity to the utensil The interface of each coating layer is selectively heat-treated, so that the thermal conductivity of the appliance is improved. Background technique [0002] The general utensils whose surface needs to be coated are almost all made of metal aluminum. In the past, utensils made of metal were used, but after use, it was found that, for example, when using utensils for cooking and eating in the kitchen, or other occasions, Problems such as scratches will occur on the surface of the above-mentioned utensil. In order to prevent the occurrence of these phenomena, a device for applying a coating liquid on the surface and forming a coati...

[0007] In addition, in order to describe the coating layer, only the coating layer of the kitchen utensils in the above case is representatively selected and described, but as a result, according to the above description, all the coating layers on the surface of the utensil The purpose is only to stay on the surface of the protective device or to reflect the aesthetic effect. The composition of the coating layer itself does not have specific properties and can exert special effects on the human body. From the point of view that it will definitely come into contact with the coating layer formed on the surface of the kitchen utensils, the fact that the composition of the coating layer of the above-mentioned kitchen utensils at least affects the raw materials of the diet cannot be ignored.

[0008] However, although cooking utensils are utensils that people eat and drink for cooking, it is also important to satisfy the physical characteristics of wear resistance, but it is even more important to have properties such as antibacterial and sterilizing that have a beneficial effect on the food to be cooked. However, the above-mentioned existing coating layer is only limited to improving physical properties such as wear resistance, and the composition of the coating layer itself does not have the characteristics beneficial to the human body at all.

[0009] In addition, the three-layer coating layer that satisfies the wear resistance has the problem that the waiting time for cooking, that is, the preheating time becomes longer and the cooking efficiency decreases due to the poor thermal conductivity.
