Izinto ezifakwe kwi-zinc

Ngaba kukho nantoni na oyibonileyo kumphezulu wentsimbi enombala o-orenji-mdaka?Ibizwa ngokuba ngumhlwa, olona tshaba lubi lwesinyithi, kwaye isiphumo sokusabela kweemolekyuli zetsimbi ene-ferrous kunye nokufuma.Umhlwa ubangela ukuthotywa kwezinto kwaye ekugqibeleni ube negalelo ekusileleni kweemveliso kunye namalungu oomatshini.Ukufakwa kweZincisetyenziselwa ukujongana nengxaki yokwakheka komhlwa ngokudala umqobo obhityileyo kumphezulu, ukuwuthintela ekudlekeni ngelixa usabele ngokusingqongileyo.

Kweli nqaku, siza kudlulaukusebenza kwe-zinc plating, amanyathelo abandakanyekayo, okuchaphazela izinto zokusebenza, iinzuzo, kunye nokunciphisa.

Yintoni iZinc Plating?

Enye indlela yokugqiba umphezulu wezixhobo ze-ferrous material kunye neemveliso kukufakwa kwe-zinc.Kubandakanya ukongeza umaleko obhityileyo kumphezulu ngaphandle kokubeka esichengeni uzinzo lwe-dimensional, ukushiya umphezulu ogudileyo, ongwevu.I-Zinc plating inika umtsalane ogqwesileyo wobuhle kwiimveliso, kodwa ngaphezulu koko, yenza ukuba iimveliso zixhathise umhlwa.Inkqubo ye-zinc plating idala i-coating encinci yokukhusela nge-electrodepositing zinc kwintsimbi eya kugqunywa, ekwabizwa ngokuba yi-substrate material.

Isebenza njani iZinc plating?

Xa i-zinc plating ibonakaliswe emoyeni, isabela ngeoksijini njengesinyithi sesinyithi kwaye ivelise i-zinc oxide (ZnO), ethi emva koko idibanise namanzi ukwenza i-zinc hydroxide (ZnoH).

I-twist iza ngoku xa i-atmospheric carbon dioxide kunye ne-zinc oxide zidibana zenze umaleko obhityileyo we-zinc carbonate (ZnCO3) encamathela kwi-zinc engaphantsi kwaye iyikhusele ngakumbi ekudlekeni.

Amanyathelo abandakanyekayo kwi-Zinc Plating

1.          Ukucocwa komphezulu

Inyathelo lokuqala kwi-zinc plating kukucoca umphezulu oza kucandwa ukususa uthuli, i-oyile, kunye nomhlwa ukuze umphezulu uqatywe nge-zinc ngokufanelekileyo.Ukucoca, i-alkaline detergents yizona zixhobo ezifanelekileyo ezingayi kuthobisa umphezulu.Nangona kunjalo, ukucocwa kweasidi kunokufakwa phambi kokusebenzisa izicoci zealkaline.

Ukuhlamba phakathi kwe-100 kunye ne-180 degrees C kunceda ukususa i-grime ngaphambi kokusebenzisa i-alkaline detergent yokucoca i-micro-level level.Emva kokucoca nge-detergent ye-alkaline, hlambulula indawo ngokukhawuleza ngamanzi adibeneyo ukuze ugweme ukonakalisa indawo ephambili yezinto, ezinokuthi izisombululo ze-alkaline ziyingozi.Ukuba ukucocwa komphezulu akwenziwanga ngokuchanekileyo, kunokubangela ukuba iZinc ixobuke okanye yonakaliswe.

2.          Ukukha

Iioksidi ezininzi, kuquka nomhlwa osele wenziwe, zinokuba phezu komhlaba.Ngoko ke, kubalulekile ukusebenzisa izisombululo ze-asidi ukususa ezi oksidi kunye nezikali ngaphambi kokuqhubeka ne-zinc plating.Ezona zisombululo zimbini ziqhelekileyo ezisetyenziswa kule nkqubo ziyi-sulfuric kunye ne-hydrochloric acid.Iimveliso ziphantsi kwesi sisombululo se-asidi.Ixesha lokudipha, iqondo lobushushu, kunye nokuNxinaniswa kweeasidi kuxhomekeke kuhlobo lwesinyithi kunye nobukhulu bezikali.

Ukulandela ukucolwa ngokuntywila amacandelo kwisisombululo se-asidi, ngokukhawuleza ucoce ngamanzi adibeneyo ukuphepha nayiphi na impendulo yobundlobongela kunye nokuthoba umgangatho.

3.          Ukulungiswa kwebhafu yokucoca

Isinyathelo esilandelayo silungiselela isisombululo se-electrolytic kwinkqubo ye-electroplating, eyaziwa ngokuba yibhafu yokucoca.Ibhafu sisisombululo se-ionic ye-zinc esinceda ekuphuculeni iinkqubo zokubeka.Inokuba yi-acid zinc okanye i-alkaline zinc;

I-Acid zinc: Ukusebenza okuphezulu, ukubekwa okukhawulezayo, amandla agqwesileyo okugquma, kodwa amandla okujula alambathayo kunye nokuhanjiswa kobukhulu obubuthathaka.

I-alkaline zinc:Ukusabalalisa ubukhulu obugqwesileyo obunamandla okujula okuphezulu, kodwa ukusebenza okuncinci kokutyalwa, isantya esisezantsi se-electro-deposition,

4.          Electrolysis Setup & Ukwazisa yangoku

Ukusekwa kweZinc-plating

Eyona nkqubo yokubeka iqala ngokwazisa umsinga wombane (DC) emva kokukhetha i-electrolyte ngokuxhomekeke kwiimfuno zemveliso kunye neenkcukacha.I-Zinc isebenza njenge-anode kwaye idityaniswe kwi-terminal engafanelekanga ye-substrate (i-cathode).I-Zinc ions idibanisa kwi-cathode (i-Substrate) njengoko umbane wombane uhamba nge-electrolytes, wenze umqobo omncinci we-zinc phezu komhlaba.

Ukongezelela, kukho iindlela ezimbini ze-electrolysis: i-rack plating kunye ne-barrel plating (iRack & Barrel plating).

·   IiRakhi:I-substrate ifakwe kwi-electrolyte ngelixa ifakwe kwi-rack, Ifanelekile kwiindawo ezinkulu

·   Umphanda:I-substrate ifakwe kwi-barrel kwaye emva koko ijikelezwe ukufumana i-plating efanayo.

5.          Emva kokulungiswa

Ukuphelisa naluphi na ungcoliseko olunokubakho kumphezulu, iindawo kufuneka zicocwe ngamanzi adityanisiweyo amaxesha amaninzi emva kokuba iplating igqityiwe.Ngaphambi kokuthumela iimveliso ezifakwe kwiiplati ukuze zigcinwe emva kokuhlamba, kufuneka zomiswe.Ukuba kuyimfuneko, i-passivates kunye ne-sealants nazo zingaqeshwa ngokusekelwe kwimigangatho efunekayo yokugqiba umphezulu.

Izinto ekufuneka ziqwalaselwe

Ukwazi eyona nto kuya kunceda ukulawula inkqubo kunye nokufumana iplating efanelekileyo.Izinto ezininzi zichaphazela umphumo wokubekwa kwi-substrate.

1.          Ukuxinana kwangoku

Ubunzima be-zinc layer, okufuneka bufakwe kwi-substrate surface, buchaphazeleka ngokuxinwa kwangoku okudlula kwi-electrodes.Ke ngoko, i-Higher Current iya kudala umaleko otyebileyo ngelixa umsinga osezantsi uza kwenza umaleko omncinci.

2.          Ubushushu bebhafu yokubeka

Enye into echaphazela i-zinc plating yiqondo lokushisa kwesisombululo se-electrolysis (i-Pating bath).Ukuba ubushushu buphezulu i-cathode idla ii-ion ze-hydrogen ezimbalwa kwisisombululo ngelixa kwangaxeshanye ithatha izikhanyisi ezininzi ukuze i-zinc plating iqaqambe ngakumbi ngenxa yokubekwa okuphezulu kwekristale yentsimbi ye-zinc.

3.          Ukugxilwa kwe-zinc kwindawo yokuhlambela

Ugxininiso lwezinc kwindawo yokuhlambela yokwambatha lukwachaphazela ukuthungwa kweplating kunye neqondo lokuqaqamba.Umzekelo, umphezulu orhabaxa uya kubangelwa kugxininiso oluphezulu ngenxa yokuba i-zinc ions iya kusasazwa ngokungalinganiyo kwaye idipozithi ngokukhawuleza.Kwelinye icala, ukugxininiswa okuphantsi kuya kubangela ukucwenga okuqaqambileyo kuba iikristale ezintle ziya kufakwa kancinci.

Ezinye izinto ziqukaindawo yee-Electrodes (i-anode kunye ne-cathode), umgangatho womphezulu we-substrate, ukuNxibeleniswa kwee-surfactants kunye nezikhanyisi kwindawo yokuhlambela, ungcoliseko., kunye nokuninzi.

Iingenelo

Ukongeza ekuthinteleni umhlwa, i-zinc plating inezinye izibonelelo ezininzi;masiye phezu ezimbalwa ngengcaciso emfutshane.

·        Ixabiso eliphantsi:Yindlela engabizi kakhulu yokugqiba umphezulu xa kuthelekiswa nezinye iindlela, kubandakanywa ukugquma umgubo, ukugqitywa kwe-oxide emnyama, kunye nesilivere yokucwenga.

·        Yomeleza:I-zinc yokwambathisa kwisinyithi, ubhedu, ubhedu, kunye nezinye ii-substrates zinceda ukwandisa amandla ezo zixhobo.

·     Uzinzo lweDimensional:Ukongeza umaleko we-zinc akuyi kuchaphazela izinto okanye uzinzo lomda weemveliso,

·        Ubuhle bobuhle:Emva kokufakwa, umphezulu we-substrate uya kubonakala ukhazimle kwaye ukhangayo, kwaye imibala inokongezwa emva kokulungiswa.

·        I-Ductility:Ngenxa yokuba i-zinc iyintsimbi ye-ductile, ukubunjwa kwe-substrate engaphantsi kwenziwa lula.
