Abstract
Working method for a system for partial mirroring of glass tubes and said system, made up by an tube supply facility, a chain where the mirroring is carried out in different fixed stations and a tube output facility, in which the main partial mirroring steps are the following: cleaning the glass tube sensitizing the surface washing optional activation or super-sensitization step washing plating washing drying in the case of external partial mirroring, the following steps are added: depositing the copper layer washing depositing anti-corrosion paint depositing mechanical and UV protective paint curing the paint external drying of the tube
