This UV dryer is used to instantaneously cure UV – curable coatings, inks, and adhesives applied to wood products. It is a crucial piece of equipment in coating line. It’s used to dry specially formulated coatings using ultraviolet light, replacing the traditional process of waiting hours for solvents to evaporate.
This six-lamp uv dryer is used to cure 4 sides of the coated substrates, top, bottom, left and right edges. It usually follows after a vacuum coater.
General
It enables high-speed, high-quality, and environmentally friendly wood finishing by using the power of ultraviolet light to instantly transform liquid coatings into a tough, durable solid film.
- It cures coatings in 3-10 seconds, which dramatically increases production speed, reduces floor space needed for drying racks, and allows for immediate handling and packaging.
- Uses mercury lamps or gallium lamps (for solid color) to produce the required UV spectrum.
Capacity
Up to 1,200m2/hour (depending on substrate type and dimension)
Applications
Any substrate that is applied with the UV curable coating material.
- A liquid UV coating (e.g., primer, sealer, topcoat) is applied to the wood surface via spray, roller, or curtain coater.
- The coated workpiece conveyor moves into the UV dryer cabinet.
- Inside, high-intensity UV lamps emit light at a specific wavelength.
- This UV light triggers a photochemical reaction in the coating’s photoinitiators (special molecules sensitive to UV light).
- This reaction causes the coating’s resins and monomers to cross-link and polymerize instantly (in seconds), transforming from a liquid to a solid, durable finish.
