Electronic cigarette as a new thing, materials, technology are in a new stage of exploration. electronic cigarette.Appearance effectAt present, it is the direction of electronic cigarette manufacturers to explore. With many new brands to join the ranks of electronic cigarettes, known as the integration of technology and fashionGradientA craze is being declared in e-cigarettes. Many electronic cigarette brands are beginning to adopt the gradient color, electronic cigarette cigarette rod gradient color is generally how to achieve it in 2018 can be described as the mobile phone back plate popular color, but in the electronic cigarette application began to explode. So far, electronic cigarettes have a lot of appearance process can choose. according to our understanding,The most common appearance effect is gradient color, and the process of gradient color is mainly anodic oxidation process.

anodic oxidationIs to form a layer on the metal surfaceoxide filmPure anodic oxidation only includes the process of generating an anodic oxide film. If you need to color the metal, you need to go through dyeing and sealing to achieve the effect of coloring.

Gradientis throughRegulating the coloring time of dyes in the dyeing tankThe dye enters the molecular gap of the oxide film during the dyeing process. The longer the dyeing time, the more dyes enter, and the deeper the color is dyed.The computer controls the time that the dyeing site stays in the dye, such as gradually pulling the workpiece away from the dye, and the uniform gradient effect can be achieved.

Specific steps are as follows:

(a) surface pretreatment of the metal workpiece;

(B) anodizing the metal workpiece to form an anodized film containing dense pores on the surface of the metal workpiece;

(c) Provide a first coloring liquid to the metal workpiece after anodization.First uniform base color treatment;

(d) providing a second coloring liquid for the metal workpiece after anodic oxidation.Gradient color processing for the second time, and make the second coloring liquid.Time of contact with the metal workpiecePreset direction along sample coloring surfacegradual change, so that the number of dye molecules entering the anode oxidation film hole in different positions gradually changes;

(e) The metal workpiece colored by the step c and the step d is rinsed clean, sealed and dried to protect the coloring effect formed.

Of course, there are still many processes that can realize gradient color, such as spraying, PVD coating, UV transfer printing, silk screen printing, color printing, etc,Only from the aspects of mass production difficulty and product yield, it is more cost-effective to realize the gradual color appearance of electronic cigarettes through anodic oxidation.
