Coloring process of a component made of dielectric or material with low conductivity and apparatus for making the same

摘要

In the present invention there is disclosed a process for dyeing a component (16) made of dielectric or a material with low conductivity. The proposed process employs a spray unit (13) of dye (20). The spray unit (13) includes a chamber that is connected to both the outlet of dye (20) and tank (46) thereof. It further includes at least one electrode (17) that is mechanically coupled and electrically connected with the component (16). Electrostatic field is generated on the basis of utilization of potential difference between the electrode (17) and another electrode being located in inner chamber of the spray unit (13), in which dye (20) is supplied from the tank (46). Dye (20) leaves after passage through the chamber the spray unit and is guided onto the component to be colored.
