Abstract
A mechanical reflection and irradiation system applicable to common ovens for cross-linking, induced by Excimer lamps, of UV-curable paints applied to three-dimensional elements, such as door parts, doors, panels, windows etc., with cubic elements, parallelepipeds and other solids of rotation and in any case of elements in general characterized by combinations of flat and vertical surfaces to obtain ultra-matt surfaces.
Claims16
Mechanical system for reflection and irradiation applicable to ovens for cross-linking UV-curable paints applied to a three-dimensional element or support, said mechanical system comprising a system for transporting and moving said three-dimensional element through:
- a painting area,
- a pre-gelling zone (step 3),
- a surface polymerization zone (phase 4), and
- a final polymerization zone (phase 5),
- in which at least the surface polymerization zone is provided with:
- a lower reflecting element;
- an upper reflective element;
- at least one Excimer lamp;
- one or more translation guides for moving the three-dimensional element, said translation guides being such as to space the three-dimensional element by a distance with respect to the lower reflecting element.
