Izinto ezenziwe nge-zinc

Ingabe kukhona okubonile ebusweni bensimbi okunombala osawolintshi-nsundu?Kubizwa ngokuthi ukugqwala, isitha sensimbi esibi kakhulu, futhi kubangelwa ukusabela kwama-molecule ensimbi enomswakama.Ukugqwala kubangela ukuwohloka kwezinto futhi ekugcineni kube nomthelela ekungasebenzini kwemikhiqizo nezingxenye zemishini.I-Zinc Platingisetshenziselwa ukubhekana nenkinga yokwakheka kokugqwala ngokwakha umgoqo omncane ongaphezulu, ukuwuvimbela ekugqwaleni ngenkathi usabela nemvelo.

Kulesi sihloko, sizodlulaukusebenza kwe-zinc plating, izinyathelo ezihilelekile, ezithinta izici zokusebenza, izinzuzo, kanye nemikhawulo.

Iyini i-Zinc Plating?

Enye indlela yokuqeda ingaphezulu yezingxenye ze-ferrous material kanye nemikhiqizo i-zinc plating.Kubandakanya ukungeza ungqimba oluncane endaweni ngaphandle kokuphazamisa ukuqina kohlangothi, okushiya indawo empunga ebushelelezi, efiphele.I-Zinc Plating inikeza ukukhanga okuhle kakhulu emikhiqizweni, kodwa ngaphezu kwalokho, kwenza imikhiqizo imelane nokugqwala.Inqubo ye-zinc plating idala ukunamathela okuncane okuvikelayo nge-electrodepositing zinc ensimbi ezogcotshwa, ebizwa nangokuthi i-substrate material.

I-Zinc Plating isebenza kanjani?

Uma i-zinc plating ivezwa emoyeni, isabela ngomoya komoyampilo njengoba kwenza izinsimbi ezisansimbi bese ikhiqiza i-zinc oxide (ZnO), ebese ihlangana namanzi ukuze yakhe i-zinc hydroxide (ZnoH).

I-twist iza manje lapho i-atmospheric carbon dioxide ne-zinc oxide kuhlangana ukwenza ungqimba oluncane lwe-zinc carbonate (ZnCO3) olunamathela ku-zinc engaphansi futhi luphinde luyivikele ekugqwaleni.

Izinyathelo Ezihilelekile Ku-Zinc Plating

1.          Ukuhlanza indawo

Isinyathelo sokuqala se-zinc plating ukuhlanza indawo ezogqitshwa ukuze kukhishwe uthuli, uwoyela nokugqwala ukuze leyo ndawo igcotshwe nge-zinc ngokuphumelelayo.Ukuze kuhlanzwe, izinto zokuhlanza ezine-alkali zingama-ejenti angcono kakhulu angeke alulaze indawo engaphezulu.Kodwa-ke, ukuhlanza i-asidi kungasetshenziswa ngaphambi kokusebenzisa izinto zokuhlanza ezine-alkali.

Ukugeza okuphakathi kuka-100 no-180 degrees C kusiza ukususa ukungcola ngaphambi kokusebenzisa okokugeza okune-alkali ukuze kuhlanzwe izinga elincane.Ngemva kokuhlanza nge-alkaline detergent, hlambulula indawo ngokushesha ngamanzi acwengekile ukuze ugweme ukulimaza indawo eyinhloko yezinto ezibonakalayo, ezingase zilimaze izixazululo ze-alkaline.Uma ukuhlanzwa kwendawo kungenziwanga ngendlela efanele, Kungase kubangele ukucwecwa kweZinc ukuthi kuxebuke noma konakale.

2.          Ukukha

Ama-oxide amaningi, okuhlanganisa nokugqwala osekwakheke kakade, angase abe ngaphezulu.Ngakho-ke, kubalulekile ukusebenzisa izixazululo ze-asidi ukususa la ma-oxide nezikali ngaphambi kokuqhubeka nokucwenga kwe-zinc.Izixazululo ezimbili ezivame kakhulu ezisetshenziswa kule nqubo yi-sulfuric ne-hydrochloric acid.Imikhiqizo icwiliswa kulesi sixazululo se-asidi.Isikhathi sokucwilisa, izinga lokushisa, kanye Nokuminyana kwama-asidi kuncike ohlotsheni lwensimbi nogqinsi lwesikali.

Ukulandela ukucosha ngokucwilisa izingxenye kusixazululo se-asidi, hlanza ngokushesha ngamanzi acwengekile ukuze ugweme noma yikuphi ukusabela okunobudlova kanye nokululaza indawo engaphezulu.

3.          Ukulungiselela okugeza Plating

Isinyathelo esilandelayo ukulungisa isisombululo se-electrolytic senqubo ye-electroplating, eyaziwa nangokuthi ukugeza okucwengayo.Ukugeza kuyisisombululo se-ionic zinc esiza ekwenzeni ngcono izinqubo zokucwenga.Kungaba i-acid zinc noma i-alkaline zinc;

I-Acid zinc: Ukusebenza kahle okuphezulu, ukufakwa okusheshayo, amandla amahle okuvala, kodwa amandla okujikijela ampofu kanye nokusabalalisa ukushuba okubuthakathaka.

I-alkaline zinc:Ukusatshalaliswa kokuqina okuhle kakhulu okunamandla okujikijela aphakeme, kepha ukusebenza kahle kwe-plating, izinga eliphansi le-electro-deposition,

4.          Ukusethwa kwe-Electrolysis & Sethula okwamanje

Ukusetha i-Zinc-plating

Inqubo yangempela yokubeka iqala ngokwethula amandla kagesi (DC) ngemva kokukhetha i-electrolyte kuye ngezidingo zomkhiqizo kanye nokucaciswa.I-Zinc isebenza njenge-anode futhi ihlanganiswe nesiphetho esinegethivu se-substrate (cathode).Ama-Zinc ions axhumeka ku-cathode (i-Substrate) njengoba amandla kagesi egeleza kuma-electrolyte, enze ungqimba oluncane lwezinki oluvimbelayo ngaphezulu.

Ukwengeza, kunezindlela ezimbili ze-electrolysis: i-rack plating kanye ne-barrel plating (I-Rack & Barrel Plating).

·   Ama-Racks:I-substrate icwiliswa ku-electrolyte ngenkathi inamathiselwe ku-rack, Ifanele izingxenye ezinkulu

·   Umgqomo:I-substrate ifakwa emgqonyeni bese ijikeleziswa ukuze ithole i-plating efanayo.

5.          Ngemuva kokucubungula

Ukuze ususe noma yikuphi ukungcola okungase kube khona endaweni, izingxenye kufanele zihlanzwe ngamanzi acwecwe izikhathi eziningana ngemva kokuqeda ukucwenga.Ngaphambi kokuthumela imikhiqizo enamapulangwe ukuze igcinwe ngemva kokugeza, kufanele yomiswe.Uma kunesidingo, ama-passivate nama-sealant nawo angasetshenziswa ngokusekelwe ezindinganisweni ezidingekayo zokuqeda phezulu.

Izinto okufanele zicatshangelwe

Ukwazi isici kuzosiza ukulawula inqubo futhi uthole i-plating efanele.Ziningi izinto ezithinta umphumela wokucwebezelisa ku-substrate.

1.          Ukuminyana kwamanje

Ugqinsi lwezingqimba lwezinki, oludinga ukufakwa endaweni engaphansi, luthintwa ukuminyana kokudlula kwamanje kuma-electrode.Ngakho-ke, i-Higher Current izodala isendlalelo esikhudlwana kanti esamanje esiphansi sizokwenza isendlalelo esincanyana.

2.          Izinga lokushisa lokugeza lokucwenga

Esinye isici esithonya i-zinc plating ukushisa kwesisombululo se-electrolysis ( ukugeza okucwengayo).Uma izinga lokushisa liphakeme i-cathode idla ama-ion e-hydrogen ambalwa esixazululweni kuyilapho ngesikhathi esifanayo ithatha izikhanyisi ezengeziwe ukuze i-zinc plating izogqama ngenxa yokubekwa okuphezulu kwe-metallic crystal ye-zinc.

3.          Ukugxila kwe-zinc kubhavu lokucwenga

Ukugxila kwe-zinc kubhavu wokucwenga kuphinde kube nomthelela ekuthungeni kwe-plating kanye nezinga lokukhanya.Isibonelo, indawo embi kakhulu izovela ekugxiliseni okuphezulu ngoba i-zinc ions izosatshalaliswa ngokungalingani futhi ifakwe ngokushesha.Ngakolunye uhlangothi, ukugxiliswa okuphansi kuzoholela ekucwecweni okukhanyayo ngoba amakristalu amahle azofakwa kancane.

Ezinye izici zihlanganisaindawo yama-Electrodes (i-anode ne-cathode), ikhwalithi yobuso be-substrate, Ukugxila kwama-surfactants kanye nezikhanyisi kubhavu wokucwenga, ukungcola, futhi nokuningi.

Izinzuzo

Ngaphezu kokuvimbela ukugqwala, i-zinc plating inezinye izinzuzo ezimbalwa;ake sidlule kokumbalwa ngencazelo emfushane.

·        Izindleko eziphansi:Kuyindlela engabizi kakhulu yokuqeda indawo engaphezulu uma kuqhathaniswa nezinye izindlela, okuhlanganisa ukugcotshwa kwempushana, ukuqedwa kwe-oxide emnyama, nokufakwa kwesiliva.

·        Qinisa:I-zinc enamathela ezinsimbi ezisansimbi, ithusi, ithusi, nezinye izinto ezingaphansi kusiza ukukhulisa amandla alezo zinto.

·     Ukuzinza kwe-Dimensional:Ukwengeza ungqimba lwezinc ngeke kuthinte ukuqina kwezingxenye noma imikhiqizo,

·        Ubuhle be-aesthetic:Ngemuva kokucwenga, i-substrate surface izovela icwebezela futhi ikhanga, futhi imibala ingangezwa ngemva kokucubungula.

·        I-Ductility:Ngenxa yokuthi i-zinc iyinsimbi eyi-ductile, ukubumba i-substrate engaphansi kwenziwa kube lula.
