Abstract

The invention provides a high-temperature color developing method and device for copper oxide, and belongs to the technical field of metal processing. The high-temperature color developing method for the copper oxide comprises the steps of copper utensil pretreatment, impurity removal, color developing, solution soaking, color fixing and the like, and specifically comprises the steps of grinding and polishing the surface of a copper utensil, evenly smearing silicon dioxide on the surface of the copper utensil, putting the copper utensil into a color developing device, heating for 5 minutes, taking out, washing with clear water, uniformly and slowly heating again, slowly increasing the temperature when the surface of the copper utensil is observed to be orange yellow, keeping the temperature for 1 minute when the surface of the copper utensil is bright red, taking out the copper utensil , naturally cooling, soaking the cooled copper utensil in a mixed solution for 5 minutes, taking out, uniformly and slowly heating again, keeping the temperature for 3 minutes after the surface is rosy, taking out, and naturally cooling to finish high-temperature color developing operation. According to the method disclosed by the invention, the color of the copper surface is changed, so that the copper utensil has the effects of oxidation resistance and corrosion resistance, and the appearance is brighter and more beautiful visually.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to a high-temperature color development method of copper oxide and a device thereof. Background technique [0002] Copper and copper alloys have good physical and chemical properties and have been widely used in many fields. However, copper is unstable in the air and is easily corroded. Nowadays, people are no longer satisfied with the monotonous brass color in the past as the surface decoration color , but tends to be richer in color and more elegant in style. [0003] The coloring of copper utensils can be carried out directly on the surface, or after the surface is oxidized or anodized to obtain an oxide film layer or to be plated with an appropriate coating. At present, the commonly used coloring processes include chemical oxidation coloring process and electrochemical coloring process. The chemical oxidation coloring process is to place the copper utensils...
