Kupaka utoto pogwiritsa ntchito electroplating ndi njira yosangalatsa yomwe yakhala ikugwiritsidwa ntchito kwa zaka mazana ambiri kuti zinthu zosiyanasiyana zizioneka bwino komanso kulimba. Njirayi imaphatikizapo kuyika chitsulo pamwamba pogwiritsa ntchito electrochemical reaction. Chimodzi mwazinthu zofunika kwambiri pa njirayi ndi electroplating rectifier, yomwe imagwira ntchito yofunika kwambiri pakuwonetsetsa kuti ntchito ya electroplating ikuyenda bwino komanso bwino. M'nkhaniyi, tifufuza nthawi yomwe zimatenga kuti zodzikongoletsera za electroplate zigwiritsidwe ntchito komanso kufunika kwa electroplating rectifier mkati mwa nthawi ino.
Njira yopangira ma electroplating
Tisanadziwe nthawi yomwe zimatenga kuti zodzikongoletsera zigwiritsidwe ntchito pa electroplate, ndikofunikira kumvetsetsa njira yopangira electroplate yokha. Njirayi imayamba ndi kukonzekera zodzikongoletsera, zomwe nthawi zambiri zimaphatikizapo kuyeretsa ndi kupukuta kuti muchotse dothi, mafuta, kapena ma oxide. Gawoli ndi lofunika kwambiri chifukwa zodetsa zilizonse zimatha kusokoneza kumatirira kwa chitsulocho.
Zodzikongoletsera zikakonzeka, zimaviikidwa mu yankho la electrolyte lomwe lili ndi ayoni achitsulo. Zodzikongoletserazo zimagwira ntchito ngati cathode (electrode yoyipa) mu electroplating circuit, pomwe anode (electrode yabwino) nthawi zambiri imapangidwa ndi chitsulo chomwe chidzaikidwa. Mphamvu yamagetsi ikadutsa mu yankholo, ayoni achitsulo amachepetsedwa ndikuyikidwa pamwamba pa zodzikongoletsera, ndikupanga wosanjikiza woonda wachitsulo.
Zinthu zomwe zimakhudza nthawi ya electroplating
Nthawi yofunikira yopangira zodzikongoletsera za electroplate imasiyana kwambiri kutengera zinthu zingapo:
1. Kukhuthala kwa Chophimba: Kukhuthala kwa chitsulo komwe kumafunidwa ndi chimodzi mwa zinthu zazikulu zomwe zimatsimikiza nthawi yopangira chophimba. Chophimba chokhuthala chimafuna nthawi yochulukirapo kuti chimalizidwe, pomwe chophimba chopyapyala chimatha kumalizidwa mwachangu.
2. Mtundu wa Chitsulo: Zitsulo zosiyanasiyana zimayikidwa pamitengo yosiyana. Mwachitsanzo, golide ndi siliva zingatenge nthawi yochepa kuti ziikidwe poyerekeza ndi zitsulo zolemera monga nickel kapena mkuwa.
3. Kuchuluka kwa Mphamvu ya Maginito: Kuchuluka kwa mphamvu yamagetsi yomwe imagwiritsidwa ntchito panthawi yopangira maginito kumakhudza kuchuluka kwa mphamvu yamagetsi yomwe imayikidwa. Kuchuluka kwa mphamvu yamagetsi kungapangitse kuti ntchito yopangira maginito ifulumizike, koma kungayambitsenso kuti zinthu zisakhale bwino ngati sizikuyendetsedwa bwino.
4. Kutentha kwa Electrolyte: Kutentha kwa electrolyte kumakhudza liwiro la njira yopangira ma electroplating. Kutentha kwa yankho kukakwera, kuchuluka kwa ma deposition kumawonjezeka mofulumira.
5. Ubwino wa chosinthira magetsi: Chosinthira magetsi ndi chinthu chofunikira kwambiri chomwe chimasintha magetsi osinthasintha (AC) kukhala magetsi olunjika (DC) kuti agwiritsidwe ntchito poyendetsa magetsi. Chosinthira magetsi chapamwamba kwambiri chimatsimikizira kuti magetsi azikhala okhazikika komanso ogwirizana, zomwe ndizofunikira kuti magetsi azigwiritsidwa ntchito mofanana. Ngati chosinthira magetsi sichikugwira ntchito bwino, chimayambitsa kusinthasintha kwa magetsi, zomwe zimakhudza kuchuluka kwa madzi ndi mtundu wonse wa magetsi.
Nthawi Yachizolowezi Yopangira Zodzikongoletsera Zamagetsi
Poganizira zinthu zomwe zili pamwambapa, nthawi yofunikira yopangira zodzikongoletsera za electroplate imatha kusiyana kuyambira mphindi zochepa mpaka maola angapo. Mwachitsanzo:
Kupaka Ma Electroplating Opepuka: Ngati mukufuna kugwiritsa ntchito golide kapena siliva wochepa pokongoletsa, njirayi ingatenge mphindi 10 mpaka 30. Izi nthawi zambiri zimakhala zokwanira pa zodzikongoletsera zomwe sizimavalidwa kawirikawiri.
Kuphimba kwapakati: Kuti kukhale kolimba kwambiri, monga golide kapena nickel wokhuthala, njira yophimba ingatenge mphindi 30 mpaka maola awiri. Nthawi ino ipanga chophimba cholimba chomwe chingapirire kuwonongeka ndi kung'ambika tsiku ndi tsiku.
Kuphimba Kokhuthala: Ngati pakufunika makulidwe akuluakulu, monga ntchito zamafakitale kapena zodzikongoletsera zapamwamba, njirayi ingatenge maola angapo. Izi ndi zoona makamaka pazinthu zomwe zimafunika kupirira nyengo zovuta kapena kugwiritsidwa ntchito pafupipafupi.
Kufunika kwa Kulamulira Ubwino
Kaya nthawi yatha bwanji, kuwongolera khalidwe ndikofunikira kwambiri pakupanga ma electroplating. Kugwiritsa ntchito chosinthira chodalirika cha ma electroplating ndikofunikira kuti magetsi aziyenda bwino nthawi zonse, zomwe zimakhudza mwachindunji ubwino wa pulasitiki. Mphamvu yosasinthasintha ingayambitse ma plating osafanana, kusagwirizana bwino komanso zolakwika monga kuphulika kwa matuza kapena matuza.
Kuphatikiza apo, kukonza ndi kuwunikira nthawi zonse chosinthira magetsi ndikofunikira kuti zitsimikizire kuti zikugwira ntchito bwino. Izi zikuphatikizapo kuyang'ana ngati pali zizindikiro zakuwonongeka kapena kulephera ndikusintha ziwalo zina ngati pakufunika kutero.
Mwachidule, nthawi yofunikira yopangira zodzikongoletsera za electroplate ingasiyane kwambiri kutengera zinthu zingapo, kuphatikizapo makulidwe ofunikira a chophimba, mtundu wa chitsulo chomwe chimagwiritsidwa ntchito, ndi mtundu wa chosinthira ma plating. Ngakhale kuti chosinthira ma plating chopepuka chingatenge mphindi zochepa chabe, kugwiritsa ntchito kwakukulu kungapangitse kuti ntchitoyi ichitike mpaka maola angapo. Kumvetsetsa zinthu izi ndikofunikira kwa okongoletsa miyala ndi okonda zosangalatsa, chifukwa zimathandiza kukonzekera bwino ndikuchita bwino njira yosinthira ma electroplating. Mwa kuonetsetsa kuti chosinthira ma plating chopangidwa bwino chikugwiritsidwa ntchito ndikusungidwa bwino, munthu amatha kupeza zodzikongoletsera zokongola komanso zolimba zomwe zidzakhalepo kwa nthawi yayitali.
