Oil and colour manufacturers offer special UV-oils. After application and having been exposed to UV-light, the surface of the wood is dry.
Application of UV-oils and UV-lacquers is done by our roller applicator DDWO and/or DWO.
Successively to our distributor conveyor, there is installed a special UV-projector above the transport belt. Wavelength is determined by the oil manufacturer. Wood is transported under the UV-projector for immediate hardening.
For the production of UV-oiled surfaces, we proceed in general as follows:
|DDWO||application of the base coat|
|Distributor conveyor||equalizing of blotchy looking spots in the wood|
|UV-drying||drying of the base coat|
|Sanding brushes||smoothing the surface|
|Cleaning brush||removal of abrasive dust|
|DWO||application of the top coat|
|UV-drying||hardening of the top coat|
With the “Wirth” UV-dryer you can dry UV-oils, UV-filler, UV-lacquer and other media with photoinitiators.
Gallium and / or mercury lamps can be used, depending on customer’s requirements.
For surfaces which are temperature sensitive, you can use also IR filters or indirect radiation on the substrate.
