Description

A UV coating equipment for wood veneer panels

Technical Field

The utility model relates to the technical field of UV coating, in particular to a UV coating device for a wood veneer panel.

Background Art

UV board is a board whose surface is protected by UV treatment. UV paint is ultraviolet light-curing paint, also known as photoinitiated coating.
