Kupanga galasi

Pamwamba pa galasi lowoneka bwino la galasi limakonzedwa ndi plating yasiliva yopanda electroless ndi vacuum evaporation. Njira yomwe imagwiritsidwa ntchito kwambiri ndi electroless silver plating. Njirayi ndikusungunula siliva nitrate m'madzi, kuwonjezera madzi ammonia ndi sodium hydroxide solution ndikuchepetsa ku silver hydroxide ammonia mchere wowirikiza kuti mupange njira yopangira siliva. Gwiritsani ntchito invert shuga kapena formaldehyde, potaziyamu sodium tartrate solution ngati madzi ochepetsera. Pambuyo galasi kudula, m'mphepete (akupera ndi opukutidwa ngati n'koyenera), pamwamba kutsukidwa, sensitized ndi dilute stannous kolorayidi njira, ndiye kutsukidwa, ndiyeno kusakaniza siliva plating njira ndi kuchepetsa njira yomweyo impregnate pamwamba, galasi pamwamba Sambani pambuyo. mapangidwe, ndiye plating yamkuwa ndi utoto woteteza ungagwiritsidwe ntchito. Njira ya vacuum evaporation ndi kuyeretsa galasi ndikuyiyika mu chipangizo cha evaporation ndi digiri ya vacuum ya 0.1-10-4Pa. Waya wa tungsten wozungulira amakhala ndi mphamvu, ndipo kutentha kwakukulu komwe kumapangidwa kumapangitsa kuti aloyi ya aluminiyamu yozungulira ikhale nthunzi kukhala mpweya, womwe umayikidwa pagalasi kuti apange galasi pamwamba. Mfuti ya elekitironi itha kugwiritsidwanso ntchito m'malo motenthetsa waya wa tungsten. Njira ya vacuum evaporation imathanso kukonza chitsulo chosalala kukhala pagalasi.
