How to deal with color difference after tungsten carbide spraying processing?

The basic processing technology of carbon tungsten spraying includes substrate surface pretreatment, painting, surface heat treatment, coating sealing treatment, and coating surface treatment. After processing, there may occasionally be slight color differences. So how should we deal with slight color differences after tungsten carbide spraying? Let's take a look with the editor.

The handling of slight color difference after tungsten carbide spraying processing is as follows:

1. Gradually fading method of refutation

In the case where the primer cannot match the color of the old paint film, in order to approach the color of the old paint film during the construction process, the color of local repairs can be gradually filtered out. That is to say, when the next layer is sprayed, an equal amount of clear varnish is added to the original diluted paint, which can reduce the color difference between the old paint and the new paint.

2. Stop partial spraying method with double-layer adhesive tape

Covering the double tape technology on the spray line and applying it to the changing parts of the car body and model, such as angles. 1、 Cover the paper with the folded tape, attach it to the corner, and then attach the second tape to the first tape. After partial correction, the visual difference of brightness and darkness on both sides of the angle can be applied to slow down the color difference between old and new paint. This method is more suitable for silver background paint effect. It should be noted that when spraying two layers of tape, it should be as thin as possible. After the film becomes dull, remove the tape and polish it to avoid hard edges.

3. Apply the whole spraying method for stopping parts of car doors or body parts

Before spraying, damaged components should be lubricated and coated with primer. Secondly, using sandpaper to stop polishing the old paint film requires spraying. Scrub with solvent, then stop part of the whole spray. After partial strikes, the boundaries between application parts can be shifted. Warm reminder: If the color difference is very serious and the color will also be different after using the above methods, then you can only repaint.
