Embodiment

[0011] A preparation process of a colored antibacterial stainless steel gas stove panel of the present embodiment comprises the following steps:

[0012] 1) Pretreatment of stainless steel parts before coloring, grinding, polishing, degreasing and activation of the surface of stainless steel parts;

[0013] 2) Put the stainless steel parts pretreated before coloring into the coloring solution, and carry out chemical oxidation coloring on the stainless steel parts. Chemical coloring, the coloring solution used is composed of: CrO 3 : 250g·L -1 , H 2 SO 4 : 4490g·L -1 , ZnSO 4 : 5g·L -1 , MnSO 4 : 4g·L -1 , (NH 4 ) 6 Mo 7 o 24 4H 2 O: 7g L -1 , OP-10: 6.25mL·L -1 ;The coloring temperature condition is 85°C;

[0014] 3) Copper electroplating is carried out on the surface of stainless steel parts after chemical oxidation and coloring to obtain colored antibacterial stainless steel.

Abstract

The invention discloses a preparation process of a color antibacterial stainless steel gas stove panel, which comprises the following steps: pretreating the stainless steel parts before coloring, polishing, polishing, degreasing and activating the surface of the stainless steel parts; The treated stainless steel parts are put into the coloring solution, and the stainless steel parts are chemically oxidized and colored. The coloring solution used is a sulfuric acid-chromic anhydride system coloring solution. Electroplate copper on the surface of the finished stainless steel parts to obtain colored antibacterial stainless steel.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a preparation process of a colored antibacterial stainless steel gas stove panel. Background technique [0002] Because of the aesthetics and cleanliness that stainless steel surfaces provide, surfaces such as building materials, transportation vehicles, household appliances, kitchen equipment, and more are often decorated with stainless steel. Colored stainless steel is generally welcomed by people because of its full aesthetic feeling and its higher use and ornamental value. Colored stainless steel not only has excellent decorative properties, but also has excellent wear resistance, corrosion resistance, heat resistance, ultraviolet radiation resistance and good mechanical processing properties. Therefore, stainless steel coloring technology has created another new field of surface treatment. Contents of the invention [0003] In order to overcome the above-m...
