Three minutes for you to understand the surface treatment steps of LED display frame

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.
