PROCESS OF APPLICATION OF ELECTRODEPOSITED COATINGS ON SOLAR MIRRORS BY FILLING Russian patent published in 2015 - IPC C25D5/02 C25D5/08 C25D7/08 F24J2/10 C09D5/24 

FIELD: process engineering.

SUBSTANCE: invention relates to application of conducting surface over the first solar mirror light reflecting coating surface. Note here that solar mirror comprises substrate with first surface and second, opposite surface. Light reflecting coating has second surface opposite the first one. Note here that said second surface is applied over the first one. Proposed method comprises placing the first conducting liquid material above the first zone of light reflecting coating first surface and placing the second conducting liquid material above the second zone of light reflecting coating second surface wherein one of said liquid materials contains the composition of electrodeposited coating. First and second conducting liquid materials are kept spaced apart and with no contact to get third zone of the first surface located between first and second zones as well as for making of electric circuit extending through the first liquid material, third zone of conducting surface and through second liquid material. Then, electric current is fed via said electric circuit to deposit protective coating over the light reflecting coating first surface that contains electrodeposited coating composition. Proposed device comprises coating application structure. Said structure comprises first channel for application of conducting coating to produce the liquid first curtain for coating application. Said structure comprises second channel for application of conducting coating to produce the liquid second curtain for coating application. Third channel serves to receive the first air blade arranged between first and second channels. Fourth conducting channel is designed to get the third liquid curtain for application of coating. Fifth channel is designed to get second air blade arranged between second and fourth channels. Also, this device includes motorised system designed to displace said structure and solar mirror relative to each other and feed system to displace first ion-containing liquid to first and fourth channels and, via the latter, to displace second ion-containing fluid to third channel and there through and for displacement of pressurised air via second and fifth channels. Note here that after activation of said feed system curtain of the first ion-containing liquid via first and fourth channels the curtain of second ion-containing liquid if displaced via second channel while pressurised air flows through third and fifth channels. After actuation of motorised system the portions of light reflecting channel first surface are displaced through the liquid curtain from first channel, pressurised air of third channel, liquid curtain from second channel, air shield of fifth channel and liquid curtain from fourth channel. Note also that pressurised air of third channel maintained first preset spacing at first surface of light reflecting coating between liquid curtains from first and second channels. Note that pressurised air of fifth channel maintains second preset spacing at first surface of light reflecting coasting between liquid curtains from second and fourth channels.

EFFECT: more homogeneous electrodeposited coating.
