For the sake of beauty, the dye is mostly sprayed on the surface of the outer casing to form a painted pattern. However, due to insufficient hardness of the plastic case, it is easily scratched or worn. Therefore, there are companies in the market that provide services such as electronic products such as mobile phones. However, the finished product after the coating lacks the feel of use 'and therefore cannot be accessed by most users. In order to enhance the hardness of the outer casing and to keep it lightweight, the use of metals such as aluminum alloys or aluminum-magnesium alloys as the outer shell of the product has also appeared on the market. Secondly, it is known that aluminum alloys are easily oxidized, and although the oxide layer has a 疋-passivation effect, and the long-term exposure of the junction $, the oxide layer will still be removed, and the protection effect is lost, and the purpose of the anode treatment is to use it for oxidation. The characteristics are controlled by an electrochemical method to prevent the formation of an oxide layer to prevent further oxidation of the aluminum material, and at the same time increase the mechanical properties of the surface, and the other purpose is to produce a color by different chemical conversion reactions to enhance the appearance. At present, the conventional anode treatment process mainly includes procedures such as degreasing, dip 3 201235513 silver, neutralization, anodizing and sealing. Among them, the degreasing system places the aluminum alloy workpiece in the warming degreasing liquid, washes away the oil stain on the surface of the aluminum alloy, and dips the aluminum alloy workpiece 1 times in the test liquid to remove the old natural oxide film on the surface of the alloy. ^ and produce a deuterium to remove the physical sorption of grease 'neutralization system will aluminum joint 1 workpiece times; soaked in nitric acid solution to neutralize the surface of the cleansing surface, blocking this gentry ... item 'anode treatment system will aluminum The alloy workpiece is placed in the electrolytic cell, the pile I* tower k' a τ is connected to the anode, and the direct current is used to make the electrolyte electrolytic, and the person who passes the slave to the aluminum alloy gradually oxidizes to form a porous color with appropriate color. Sexual photo I.. „ 〆 轧 rolling film, sealing system will be anodized after the surface of the alloy, the small hole of the etched oxide film is sealed, to achieve smooth, wear-resistant, corrosion-resistant performance. After that, the laser-like engraving or CNC destruction of the surface oxide film is used to form the desired pattern and text mark on the surface of the workpiece. The text is only limited to the color of the alloy itself. Cannot render other Color, and the industry is considering the texture, the color of the oxide film is often colorless or light, but in this case, the text mark is bound to be quite inconspicuous. In addition, 'the pattern and the text mark are in the way of destroying the surface oxide film. Therefore, the pattern and the text mark will inevitably lose the hardening and protection effect. To overcome the above problem, 'someone tried to multi-color on the anodized workpiece to make the pattern more change, and the odd way is roughly the following : The processing component is deoiled and washed for anode treatment 201235513 and a single-eighth & flat color is formed on the processing component. The color portion of the knife to be retained is coated with anti-corrosion touch ink, and iτ ” ^ . Placed in a nitric acid treatment tank, the surface of the uncoated ink surface is fading and etched, and then the processing element is placed in an electrolytic cell containing the _ color dye solution for anodizing. The second color is formed by the surface of the surface which is faded and corroded by the surface of the nitrate, and the same color is used to process according to the number of the desired color. When the steps are completed in a variety of colors, the ink is removed by an organic solvent, and the soil is sealed into the surface to form a protective film layer, and the layer is treated by the layer. The processing procedure is complicated and consumes a lot of X 0 The main .. m temple, and the use of a large number of dyes, in addition to increasing costs, also caused pollution. First, the processing 7C piece is subjected to the first-anodic processing coloring process, and the first color is formed on the surface of the processing element, and then the processing is performed: the removal method is to remove the second color portion and remove the first color of the portion. 'The second color of the anode treatment t color program. In addition to using the machining and cutting removal method, it is also possible to use a laser to sinter part of the surface to remove the first color of the part, and so on, according to the required number of colors, the same step, and finally the medicated water sealing Forming a surface protective film ^, in this way, is also time consuming, labor-intensive and uses more dyes, which increases the cost and causes pollution, and dyes the dye multiple times, so that the different colors are colored. Contamination occurs in the middle, resulting in a chromatic aberration, which leads to an increase in defective products. 3: Firstly, the first color is colored by the anode treatment 201235513. Then, the fading agent, such as hydrogen peroxide, is used to remove part of the color, and then anodized to perform the second color treatment on the color removal part. And so on, finally the drug seal is formed to form a surface protective film layer. However, such a process is also time consuming and labor intensive, and uses more dyes, which increases the cost and causes pollution, and dyes the dye multiple times, so that the different colors are contaminated by the coloring, thereby causing chromatic aberration. It also increases the number of defective products. SUMMARY OF THE INVENTION The main object of the present invention is to provide an anode processing coloring method which can increase the hardness of a painted layer to reduce the chance of the patterned layer being peeled off due to injury or bruising.

Due to static electricity, small ink drops after the electric field Regardless of the charge or not, the flight is straight ahead. When the 1st field deviates from the plate 1433, the amount of charge (4) will be strongly induced and the twist will be larger. On the contrary, the deflection is smaller, and the charged ink droplets will be collected in the ink collection groove. When the field is subjected to the sealing treatment, the pores 13 of the film layer 12 are sealed to form a non-adsorptive surface, or the agent or the like 4 10 201235513 is infiltrated into the pores to change or improve the characteristics of the skin layer. The sealing process involves dissolving the oxide or hydroxide in the pores or depositing other materials in the pores to form a dense surface having properties. The sealing operation can be carried out in a dichromic acid solution in addition to being carried out in water to improve corrosion resistance. Since the painted pattern 丨6 formed by the dye 15 is sealed in the film layer 12 after being sealed, the painted pattern 16 can be scratch-resistant and wear-resistant, and can be used by the user for a long time. The appearance of the outer casing can still maintain a certain quality.
