Kusintha kulikonse kuli ngati zodzoladzola za anthu. Pamwamba pake pamafunika kuphimbidwa ndi zigawo zingapo kuti amalize kukongoletsa pamwamba. Makulidwe a zokutira amawonetsedwa mu ma microns. Nthawi zambiri, kutalika kwa tsitsi kumakhala ma microns makumi asanu ndi awiri kapena makumi asanu ndi atatu, ndipo zokutira zachitsulo ndi masauzande angapo. Chopangidwacho chimapangidwa ndi kuphatikiza zitsulo zosiyanasiyana ndipo chimakutidwa ndi zigawo zingapo zazitsulo zosiyanasiyana kuti amalize kupanga. ndondomeko. Nkhaniyi ikufotokoza mwachidule chidziwitso choyenera cha electroplating ndi color plating. Zomwe zili m'bukuli ndizomwe abwenzi omwe amagula ndi kupereka makina apamwamba kwambiri amapakira:
Electroplating ndi njira yomwe imagwiritsa ntchito mfundo ya electrolysis kuyika zitsulo zopyapyala kapena ma aloyi pamwamba pazitsulo zina. Ndi njira yomwe imagwiritsa ntchito electrolysis kuti ingagwirizane ndi filimu yachitsulo pamwamba pa zitsulo kapena zigawo zina zakuthupi kuti zisawonongeke zitsulo zachitsulo (monga dzimbiri), zimathandizira kuvala kukana, conductivity, reflectivity, kukana kwa dzimbiri (zitsulo zokutidwa nthawi zambiri zimakhala zitsulo zosagwira dzimbiri. ) ndikuwongolera mawonekedwe.
Mfundo yofunika
Electroplating imafuna magetsi otsika kwambiri, omwe ali ndi magetsi apamwamba omwe amapereka mphamvu ku thanki ya electroplating ndi chipangizo cha electrolytic chokhala ndi njira yopangira, zigawo zomwe ziyenera kuikidwa (cathode) ndi anode. The electroplating ndondomeko ndi ndondomeko imene ayoni zitsulo mu plating njira kuchepetsedwa kukhala maatomu zitsulo kudzera elekitirodi zimachitikira pansi pa zochita za kumunda magetsi kunja, ndi mafunsidwe zitsulo ikuchitika pa cathode.
Zogwiritsidwa ntchito
Zovala zambiri ndi zitsulo kapena ma alloys amodzi, monga titaniyamu, palladium, zinki, cadmium, golide kapena mkuwa, mkuwa, ndi zina zotero; palinso zigawo zobalalika, monga faifi tambala-silicon carbide, faifi tambala-fluorinated graphite, etc.; ndi cladding zigawo, monga zitsulo Copper-nickel-chromium wosanjikiza pa chitsulo, siliva-indidium wosanjikiza pa chitsulo, etc. Kuwonjezera chitsulo ofotokoza chitsulo, zitsulo ndi zitsulo zosapanga dzimbiri, zipangizo m'munsi kwa electroplating mulinso sanali ferrous. zitsulo, kapena mapulasitiki a ABS, polypropylene, polysulfone ndi mapulasitiki a phenolic. Komabe, mapulasitiki amayenera kuthandizidwa mwapadera komanso chithandizo chamankhwala asanayambe kupangidwa ndi electroplating.
Plating mtundu
1) Kupaka zitsulo zamtengo wapatali: monga platinamu, golide, palladium, siliva;
2) General zitsulo plating: monga kutsanzira platinamu, wakuda mfuti, faifi tambala wopanda malata cobalt, mkuwa wakale, mkuwa wofiira wakale, siliva wakale, malata akale, etc.
Malinga ndi zovuta za ndondomekoyi
1) Mitundu yambiri yopaka utoto: platinamu, golide, palladium, siliva, platinamu, mfuti yakuda, malata opanda faifi tambala, nickel wa ngale, kupaka utoto wakuda;
2) Kuyika kwapadera: plating yachikale (kuphatikiza patina wothira mafuta, patina wopaka utoto, patina wopangidwa ndi ulusi), mitundu iwiri, kupaka mchenga, kuyika burashi, ndi zina zambiri.
1 platinamu
Ndichitsulo chokwera mtengo komanso chosowa. Mtundu wake ndi woyera wasiliva. Ili ndi katundu wokhazikika, kukana kwabwino kwa kuvala, kuuma kwakukulu ndi nthawi yosungira mtundu wautali. Ndi imodzi mwamitundu yabwino kwambiri ya electroplating. makulidwe ndi pamwamba 0,03 microns, ndi palladium zambiri ntchito ngati wosanjikiza pansi kukhala ndi zotsatira zabwino synergistic, ndi chisindikizo akhoza kusungidwa kwa zaka zoposa 5.
2 platinamu wotsanzira
Chitsulo cha electroplating ndi copper-tin alloy (Cu / Zn), ndipo platinamu yotsanzira imatchedwanso white copper-tin. Mtundu uli pafupi kwambiri ndi golide woyera komanso wachikasu pang'ono kuposa golide woyera. Zinthuzo ndi zofewa komanso zamoyo, ndipo zokutira pamwamba ndizosavuta kuzimiririka. Ngati yatsekedwa, ikhoza kusiyidwa kwa theka la chaka.
3 golide
Golide (Au) ndi chitsulo chamtengo wapatali. Wamba kukongoletsa plating. Zosakaniza zosiyanasiyana zimabwera mumitundu yosiyanasiyana: 24K, 18K, 14K. Ndipo mu dongosolo ili kuchokera ku chikasu kupita ku wobiriwira, padzakhala kusiyana pakati pa makulidwe osiyanasiyana. Ili ndi zinthu zokhazikika ndipo kuuma kwake nthawi zambiri kumakhala 1/4-1/6 ya platinamu. Kukana kwake kuvala kumakhala pafupifupi. Chifukwa chake, moyo wa alumali wamtundu wake ndi wapakati. Golide wa rose amapangidwa ndi golide-mkuwa alloy. Malingana ndi kuchuluka kwake, mtunduwo uli pakati pa golide wachikasu ndi wofiira. Poyerekeza ndi golide wina, imakhala yosangalatsa, yovuta kulamulira mtundu wake, ndipo nthawi zambiri imakhala yosiyana mitundu. Nthawi yosungiramo mtundu nayonso si yabwino ngati mitundu ina ya golide ndipo imasintha mtundu mosavuta.
4 siliva
Siliva (Ag) ndi chitsulo choyera chomwe chimagwira ntchito kwambiri. Siliva amasintha mtundu mosavuta akakumana ndi ma sulfide ndi ma chlorides mumlengalenga. Silver plating nthawi zambiri imagwiritsa ntchito chitetezo cha electrolytic ndi electrophoresis chitetezo kuti zitsimikizire moyo wa plating. Pakati pawo, moyo wautumiki wa chitetezo cha electrophoresis ndiutali kuposa wa electrolysis, koma ndi chikasu pang'ono, zinthu zonyezimira zimakhala ndi mapini ang'onoang'ono, ndipo mtengowo udzawonjezeka. Electrophoresis imapangidwa pa 150 ° C, ndipo zinthu zotetezedwa ndi izo sizophweka kukonzanso ndipo nthawi zambiri zimachotsedwa. Silver electrophoresis ikhoza kusungidwa kwa chaka choposa 1 popanda kusintha.
5 mfuti yakuda
Metal material nickel/zinc alloy Ni/Zn), wotchedwanso mfuti yakuda kapena nickel wakuda. Mtundu wa plating ndi wakuda, wotuwa pang'ono. Kukhazikika kwapamwamba ndikwabwino, koma kumakonda kukongoletsa pamilingo yotsika. Mtundu wa plating uwu umakhala ndi faifi tambala ndipo sungagwiritsidwe ntchito pakupanga zinthu zopanda faifi. Kupaka utoto sikophweka kukonzanso ndikusintha.
6 nickel
Nickel (Ni) ndi yotuwa-yoyera ndipo ndi chitsulo cholimba kwambiri komanso cholimba. Nthawi zambiri amagwiritsidwa ntchito ngati chosindikizira cha electroplating kuti apititse patsogolo moyo wautumiki wa electroplating. Ili ndi luso loyeretsa bwino mumlengalenga ndipo imatha kukana dzimbiri kuchokera mumlengalenga. Nickel ndi yolimba komanso yosasunthika, kotero siyoyenera kuzinthu zomwe zimafuna kupunduka panthawi ya electroplating. Zinthu zopangidwa ndi nickel zikapunduka, zokutira zimang'ambika. Nickel ikhoza kuyambitsa kusagwirizana ndi khungu mwa anthu ena.
7 Kupaka tin-cobalt kopanda Nickel
Zomwe zimapangidwa ndi tin-cobalt alloy (Sn/Co). Mtundu wake ndi wakuda, pafupi ndi mfuti yakuda (yotuwa pang'ono kuposa mfuti yakuda), ndipo ndi plating yakuda yopanda faifi. Pamwambapa ndi okhazikika, ndipo otsika mlingo wa electroplating sachedwa mtundu. Kupaka utoto sikophweka kukonzanso ndikusintha.
8 ngale
Zinthu zake ndi faifi tambala, wotchedwanso mchenga faifi tambala. Nthawi zambiri amagwiritsidwa ntchito ngati chisanadze chokutidwa pansi wosanjikiza wa mtundu chifunga ndondomeko. Mtundu wotuwa, wagalasi wosanyezimira, wokhala ndi mawonekedwe ofewa ngati nkhungu, ngati satin. Mlingo wa atomization ndi wosakhazikika. Popanda chitetezo chapadera, chifukwa cha chikoka cha zinthu zopangira mchenga, pakhoza kukhala kusinthika pokhudzana ndi khungu.
9 mtundu wa chifunga
Zimakhazikitsidwa ndi nickel ya ngale kuti iwonjezere mtundu wa pamwamba. Imakhala ndi chifunga ndipo ndi ya matte. Njira yake yopangira ma electroplating ndi nickel ya ngale. Chifukwa mphamvu ya atomization ya ngale ya nickel ndizovuta kuwongolera, mtundu wapamtunda sugwirizana komanso umakonda kusiyanasiyana kwamitundu. Mtundu wa plating uwu sungagwiritsidwe ntchito ndi plating wopanda faifi tambala kapena ndi mwala pambuyo plating. Mtundu wa plating uwu ndi wosavuta kutulutsa oxidize, choncho chisamaliro chapadera chiyenera kuperekedwa ku chitetezo.
10 zopaka waya za brush
Pambuyo pazitsulo zamkuwa, mizere imatsukidwa pamkuwa, ndiyeno mtundu wa pamwamba umawonjezeredwa. Pali lingaliro la mizere. Maonekedwe ake ndi ofanana ndi mtundu wamba wamba, koma kusiyana kwake ndikuti pali mizere pamwamba. Mawaya akutsuka sangakhale plating wopanda faifi tambala. Chifukwa cha plating wopanda faifi tambala, moyo wawo sungakhale wotsimikizika.
11 kuwomba mchenga
Sandblasting ndi imodzi mwa njira za electroplating chifunga mtundu. The copper plating ndi sandblasted ndiyeno electroplated. Pamwamba pa matte ndi mchenga, ndipo mtundu womwewo wa matte umawoneka bwino kuposa momwe mchenga umakhalira. Monga plating burashi, plating wopanda faifi tambala singachite.
