Ukusetshenziswa kwe-Electrochemistry ku-Metal Plating
I-Pendahuluan
Ekuthuthukisweni kobuchwepheshe kanye nemboni, ukugoba ngensimbi sekuyinto ebalulekile nebalulekile. Le ndlela yokugoba inezinhlelo zokusebenza eziningi ezithinta imikhakha eyahlukene yezimboni, kusukela kwezezimoto kanye ne-elekthronikhi kuya ekwakheni ngisho nobucwebe. Enye indlela esetshenziswa kakhulu ekugoba ngensimbi ubunjiniyela be-electrochemical. Lesi sihloko sizoxoxa ngezici ezahlukahlukene zokusetshenziswa kwe-electrochemical ekugoba ngensimbi, kusukela ezimisweni eziyisisekelo kuya ekusetshenzisweni kwezimboni.
Izimiso Eziyisisekelo ze-Electrochemistry
I-Electrochemistry iyigatsha le-chemistry elifunda ubudlelwano phakathi kwezehlakalo zikagesi kanye nokusabela kwamakhemikhali. Ezinqubweni ze-electrochemical, ugesi usetshenziselwa ukushayela ukusabela kwamakhemikhali okungahleliwe. Inqubo ye-electrolytic metal plating, evame ukubizwa ngokuthi i-electroplating, iwukusetshenziswa okuyinhloko kwalesi simiso esiyisisekelo se-electrochemistry. Empeleni, i-electroplating ihilela ukufakwa kwengqimba encane yensimbi phezu kobuso bento ngokunciphisa ama-ion ensimbi esixazululweni se-electrolyte ngogesi kagesi.
Isimiso esiyisisekelo sokupenda nge-electrode sihilela ama-electrode amabili (i-anode ne-cathode) acwiliswe esixazululweni se-electrolyte, lapho insimbi ezobekwa khona itholakala ngesimo se-ionic. Uma kusetshenziswa ugesi, ama-ion ensimbi aya e-cathode (i-electrode engemihle), lapho encishiswa khona futhi anamathele ebusweni bento yokusebenza, esebenza njenge-cathode.
Izinto Ezisetshenziswa Ekufakeni Ama-Electroplating
Ukukhethwa kwezinto zokusetshenziswa enkambisweni yokufakelwa i-electroplating kubalulekile futhi kuyahlukahluka kuye ngezidingo zokusetshenziswa kanye nezimboni. Ezinye izinsimbi ezivame ukusetshenziswa ekufakweni kwe-electroplating zifaka:
1. I-Nickel – Isetshenziselwa ukwandisa ukumelana nokugqwala nokuguguleka. I-Nickel plating inikeza ubuso obukhazimulayo kanye nobuhle obuhle.
2. Ithusi – Ngokuvamile lisetshenziswa njengesembozo sangaphambi kokufaka ezinye izinsimbi. Ithusi linikeza ugesi omuhle kanye nokunamathela ezingqimbeni zensimbi ezilandelayo.
3. I-Chromium – Isetshenziselwa ukuhlobisa noma ukwandisa ukumelana nokugqwala. Isembozo se-chromium sinikeza ukubukeka okukhazimulayo nokuqinile.
4. Igolide – Lisetshenziswa kakhulu embonini ye-elekthronikhi ukuthuthukisa ukuhanjiswa kukagesi kanye nokumelana nokushiswa.
5. I-Zinc – Isetshenziselwa ukuvimbela ukugqwala nokuvikela insimbi eyisisekelo ekugqwaleni ngokusebenzisa i-galvanic coating.
Indlela Yokufaka I-Electroplating
Inqubo yokufaka i-electroplating ingenziwa kusetshenziswa izindlela ezahlukahlukene, kuye ngokuthi umkhiqizo ungakanani kanye nezidingo ezithile zesicelo. Nazi ezinye zezindlela ezivamile zokufaka i-electroplating:
1. I-Barrel Electroplating – Isetshenziselwa ukugoqa izingxenye ezincane ngobuningi obukhulu. Umsebenzi ufakwa esigubheni esijikelezayo esixhunywe kuma-electrode ukuze ukugoqa kwenzeke ngokulinganayo.
2. I-Rack Electroplating - Isetshenziselwa izingxenye ezinkulu noma eziyinkimbinkimbi. Umsebenzi ubekwa ku-rack exhunywe kuma-electrode enqubo yokubopha.
3. Ukumboza Ngebhulashi – Indlela yokumboza esetshenziswa endaweni ethile esebenzisa ibhulashi ukufaka isisombululo se-electrolyte ngqo endaweni ethile. Le ndlela iwusizo ekulungiseni noma ekusetshenzisweni okukhethekile okudinga ukumboza endaweni elinganiselwe.
Izicelo Embonini
Izithuthi
Imboni yezimoto ingenye yabasebenzisi abakhulu bobuchwepheshe be-electrochemical ekufakeni izinsimbi. Izingxenye zezimoto ezifana nama-bumpers, ama-rim, kanye nama-engine bay zivame ukufakwa izinsimbi ukuze kwandiswe ukumelana nokugqwala, kuthuthukiswe ubuhle, futhi kunikeze isikhathi eside sokuphila. I-Chromium plating ngaphandle kwezimoto, isibonelo, inganikeza ukukhanya okuhlala isikhathi eside futhi ivikele izingxenye ezindaweni zangaphandle ezinzima.
electronics
Embonini ye-elekthronikhi, i-electroplating isetshenziselwa ukuqinisekisa ukuthi izingxenye zikagesi zinokudluliswa okuphezulu komoya futhi ziyamelana nokushiswa komoya. Ukudluliswa kwegolide kuma-contact kagesi namabhodi wesekethe aphrintiwe (ama-PCB) kuvamile ukuqinisekisa ukusebenza kahle kanye nokuphila isikhathi eside kwenkonzo. Igolide lisetshenziselwa ukumelana nokugqwala kwalo kanye nokudluliswa okuphezulu komoya, okubaluleke kakhulu kumadivayisi kagesi asebenza kahle kakhulu.
Konstruksi
Imboni yokwakha iphinde isebenzise kakhulu ubuchwepheshe bokufaka i-electroplating. Ukwembozwa kwensimbi kumathuluzi okwakha, imishini, kanye nezingxenye zesakhiwo ezifana nama-bolts namantongomane kuqinisekisa ukuthi le mishini nezinto zokwakha zihlala isikhathi eside futhi ziqinile ngokumelene nezinto eziyingozi zemvelo. Isibonelo, insimbi yesakhiwo ye-zinc noma i-galvanizing iphumelela kakhulu ekuvimbeleni ukugqwala, okungenza buthaka amandla ezinto zokwakha.
Ubucwebe
Imboni yobucwebe ingomunye wemikhakha esebenzisa i-electroplating ukudala ukubukeka okuhle kakhulu kwekhwalithi ephezulu emikhiqizweni yayo. Ukufaka izinsimbi eziyigugu njengegolide nesiliva ebucwebeni obenziwe ngezinto eziyisisekelo ezingabizi kakhulu kungakhiqiza imikhiqizo eqediwe emihle nengabizi kakhulu. Inqubo yokufaka i-plating ivumela nemibala ehlukahlukene kanye nokuthungwa ebusweni bobucwebe, okudala imiklamo ekhanga abathengi.
Izinselele Nokusungula Izinto Ezintsha
Nakuba i-electroplating iyindlela ephumelela kakhulu futhi eguquguqukayo, ibhekene nezinselele eziningana ezinkulu. Enye yalezi izinkinga zemvelo. Inqubo ye-electroplating isebenzisa amakhemikhali ayingozi angangcolisa imvelo uma ingaphathwa kahle. Ukuphathwa kwemfucuza kanye nokusetshenziswa kabusha kwamakhemikhali kubalulekile ekusimeni kule mboni.
Ukusungula izinto ezintsha kubuchwepheshe bokufaka ama-electroplating kuyaqhubeka nokukhula ukuze kuxazululwe lezi zinselele. Ukusetshenziswa kwamakhemikhali anobungani nemvelo kanye nobuchwepheshe bokwelapha amanzi amdaka obusebenza kahle kakhulu kuyizinto ezibalulekile ocwaningweni lwamanje. Ngaphezu kwalokho, amasu okufaka ama-electroplating athuthukile njenge-nanoelectroplating nawo ayathuthukiswa ukuze ahlinzeke ngezingubo ezinembile nezisebenzayo.
Isiphetho
Izembozo ze-electrochemical zinikeza ikhambi elisebenziseka ngezindlela eziningi elisetshenziswa ezimbonini ezahlukahlukene ukuthuthukisa ukuqina komkhiqizo, ubuhle, kanye nokusebenza kwawo. Lezi zindlela zisebenzisa izimiso eziyisisekelo ze-electrochemistry ukudala izendlalelo zensimbi ezincane ezinezici ezifiselekayo. Naphezu kwezinselele zemvelo, ukusungula izinto ezintsha kwezobuchwepheshe kanye nemikhuba enobungani nemvelo kuzoqhubeka nokuqhuba intuthuko kulo mkhakha. Ngakho-ke, izembozo ze-electrochemical zizoqhubeka nokudlala indima ebalulekile ekuthuthukisweni kwezimboni kanye nobuchwepheshe esikhathini esizayo.
