IPC: B05B13/02
Filed: 2002-03-12
Abstract: <P>PROBLEM TO BE SOLVED: To automate a coating process for silver films and to improve quality by preventing 'yellowing' of the silver films.  <P>SOLUTION: In the process that works W are conveyed to a specified direction by a conveyer 3, an aqueous silver nitrate solution jetted from a spray unit 54 for jetting the aqueous silver nitrate solution, an aqueous ammonia water solution jetted from a spray unit 55 for jetting the aqueous ammonia water solution and a reducing liquid jetted from a spray unit 51 for jetting the reducing liquid mix on the surfaces of the works W and precipitate the silver. The excess liquid is flushed away by the pure water jetted from pure water spray units 53 and 56 and therefore the silver films are continuously and successively formed at a uniform film thickness on the surfaces of the works W. The silver films are completely removed of moisture by a drying unit 6 and therefore the yellowing occurring in the moisture of the silver film surfaces is prevented and the silver luster of a high grade can be obtained.  <P>COPYRIGHT: (C)2003,JPO
