Problems solved by technology

[0002] The production process of aluminum alloy cookware includes the step of electrolytic coloring. In the traditional production process, after the aluminum alloy cookware is electrolytically colored by copper salt, it will be placed in high-temperature hot water to cure the color of the surface of the cookware. However, the aluminum alloy that has just completed electrolytic coloring The color of the cookware will change after a few minutes in the air or water, and the cured color effect obtained is not ideal, which will affect the appearance of the aluminum alloy cookware

Embodiment Construction

[0018] An electrolytic coloring process for aluminum alloy cookware, comprising the following steps: 1), polishing, such as figure 1 As shown, the surface of the workpiece 2 to be processed is polished mechanically, so that the surface of the workpiece 2 reaches the mirror brightness. The abrasive type used for polishing is ultrafine powder liquid wax, and the polishing wheel 1 is a flannelette wheel. The peripheral speed in the polishing process is 20~100m / s, pressure 0.5~4kg / cm 2 , the polishing time is 0.5~5min, and a smooth barrier layer 21 is formed on the surface of the workpiece 2 after polishing; 2) Cleaning, using low-pressure rotary stepping jet cleaning technology, using a degreasing agent with high cleaning power and high-efficiency surface-active cleaning agent Clean the surface of the polished workpiece 2, and maintain the mirror effect of the workpiece 2 while cleaning the surface of the workpiece 2; 3), oxidize the workpiece 2 with a smooth surface obtained in ...

Abstract

The invention discloses an electrolytic coloring technique of an aluminum alloy cooker, which comprises the following steps: 1) polishing: carrying out surface polishing on a workpiece to be processed; 2) cleaning: cleaning the workpiece surface; 3) oxidation: using a sulfuric acid direct-current anodization technique to generate a colorless high-transparency anode oxide film on the workpiece surface, wherein the oxide film is uniformly distributed with micropores; 4) electrolytic coloring: putting the workpiece with the oxide film obtained in the step 3 into a cupric salt electrolyte, and electrifying for electrolysis, so that the ionized copper ions are attached to the micropores of the surface oxide film of the aluminum alloy cooker to form a color layer; 5) color fixation: soaking the colored workpiece in hot water for 1-2 minutes; and 6) sanding the surface of the workpiece obtained in the step 5 so that the copper ions are sealed in the oxide film. By using the technique disclosed by the invention, after the cooker is colored, the color layer is effectively protected, so that the cooker can have bright color for a long time, and can not become discolored; and thus, the aesthetic degree and use safety of the cooker are enhanced.

Description

technical field [0001] The invention relates to a cooking process for cooking utensils, in particular to an electrolytic coloring process for aluminum alloy cooking utensils. Background technique [0002] The production process of aluminum alloy cookware includes the step of electrolytic coloring. In the traditional production process, after the aluminum alloy cookware is electrolytically colored by copper salt, it will be placed in high-temperature hot water to cure the color of the surface of the cookware. However, the aluminum alloy that has just completed electrolytic coloring The color of the cookware will change after a few minutes in the air or water, and the resulting cured color effect is not ideal, which affects the appearance of the aluminum alloy cookware. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide an electrolytic coloring process for aluminum alloy cookware, so that the surface col...
