PREPARATION OF COLORED COATED METAL WIRE

摘要

PURPOSE:To improve manufacturing efficiency, by coating a colored ultraviolet curable resin solution containing a small amount of a fluorine compound to a coated metal wire preliminarily coated with an uncolored coating material and irradiating the coating layer with ultraviolet rays. CONSTITUTION:An uncolored enamel wire C is delivered from a winder 7 to be sent to a painting part 8 and coated with a colored ultraviolet curable resin solution. Thereafter, the coating layer is irradiated with ultraviolet rays in an ultraviolet irradiation apparatus 9 to obtain a colored enamel wire D. Two sets of reflective mirrors are radially provided in the ultraviolet irradiation apparatus 9 and an ultraviolet lamp is positioned at a first focus and the uncolored enamel wire C is allowed to pass the second focus thereof. The colored enamel wire D is taken up by a winder 13 at last.
