LED panel is a kind of display screen used to display text, graphics, images, animations, quotations, videos, video signals and other information by controlling semiconductor LED. Today, I'm going to talk about the surface treatment steps of LED display frame.
1. Passivation. The technological process is: after galvanizing → washing → polishing → washing → passivation → washing → sealing → drying (aging).
2. Staining after passivation. The technological process is: passivation → washing → dyeing → washing → drying.
3. Phosphating. The technological process is: galvanizing → washing → adjusting → phosphating → sealing → drying.
4. Hydrogen treatment after galvanizing. The technological process is as follows: galvanizing → washing → oxygen removal → polishing → washing → passivation → washing → drying.
The above is about the surface treatment steps of LED display frame, hoping to help you. Let's see you next time.
