Tšebeliso ea Sodium Cyanide ho Indasteri ea Electroplating

Electroplating ke ts'ebetso ea bohlokoa indastering ea tlhahiso, e kenyelletsang ho beha karolo e tšesaane ea tšepe holim'a sesebelisoa sa tšepe ka electrolysis. Ts'ebetso ena ha e ntlafatse feela ho hanyetsa ha tšepe ea tšepe empa hape e ntlafatsa ponahalo ea eona e ntle le boleng ba bokaholimo. Sodium cyanide, motsoako oa lik'hemik'hale o chefo haholo empa o sebetsa ka mefuta-futa, o phetha karolo ea bohlokoa ho electroplating khoebo.

Lintho tsa Motheo tsa Electroplating

Electroplating e itšetlehile ka molao-motheo oa electrolysis. Ka setupong sa electroplating, tšepe ea tšepe e tla kenngoa e entsoe ka cathode, ha tšepe e tla kenngoa e sebelisoa e le anode. Ka bobeli cathode le anode li qoelisoa ka tharollo ea electrolyte e nang le li-ion tsa tšepe tsa tšepe ea plating. Ha motlakase o fetisoa ka electrolyte, li-ion tsa tšepe tse ka har'a tharollo li hoheloa ke cathode (sesebelisoa sa mosebetsi) 'me se behoa holim'a sona, se etsa sekhahla se tšesaane, se ts'oanang sa tšepe ea plating.

Karolo ea Sodium Cyanide ho Electroplating

Sodium cyanide (NaCN) e sebelisoa haholo ho electroplating e le a Complexing Agent. E na le bokhoni ba ho etsa li-complexes tse tsitsitseng tse nang le li-ion tse sa tšoaneng tsa tšepe. Tabeng ea electroplating, lisebelisoa tsena tsa tšepe - cyanide li na le melemo e mengata:

1. Boleng bo ntlafetseng ba Plating: Metal - cyanide complexes e entsoeng ke Sodium cyanide thusa ho finyella ho feta junifomo le boreleli tšepe deposition holim'a workpiece. Ka mohlala, ka electroplating ea koporo, motsoako oa koporo - cyanide o etsa bonnete ba hore li-ion tsa koporo li kenngoa ka ho lekana, e leng se etsang hore ho be le sekhahla sa koporo se teteaneng le se khomarelang. Sena ke sa bohlokoa bakeng sa lits'ebetso moo ho ts'epahala ha lesela le pota-potiloeng ho leng bohlokoa, joalo ka indastering ea lisebelisoa tsa elektroniki bakeng sa likhokahano tsa plating.

2. Tšebeliso e Ntlafetseng: Tšebeliso ea sodium cyanide ka tharollo ea electrolyte e ntlafatsa matla a ho lahlela a bate ea plating. Matla a ho lahlela a bolela bokhoni ba tharollo ea plating ea ho kenya lesela le ts'oanang la tšepe holim'a sesebelisoa sa mosebetsi, esita le likarolong tse rarahaneng tse nang le li-recesses le li-protrusions. Lisebelisoa tsa tšepe - cyanide li ka fihla likarolong tsohle tsa mosebetsi, ho netefatsa hore li koahetsoe ka ho feletseng. Sena se molemo haholo liindastering tse kang tsa likoloi, moo likarolo tse nang le li-geometri tse rarahaneng li hlokang ho petoa bakeng sa tšireletso ea kutu.

3. Bath e tsitsitseng ea Plating: Sodium cyanide e thusa ho boloka botsitso ba bate ea electroplating. E laola mahloriso a li-ion tsa tšepe tse sa lefelloeng ka tharollo, ho thibela ho thehoa ha li-deposit tsa tšepe tse sa sebetseng hantle - tse khomaretsoeng kapa tsa boleng bo tlaase. Ka ho etsa li-complexes tse tsitsitseng, e lumella hore ho be le mokhoa o laoloang le o tsitsitseng oa electroplating.

Lisebelisoa tse khethehileng tsa Sodium Cyanide ho Electroplating

1. Ho roala Koporo: Ka electroplating ea koporo, Sodium cyanide e sebelisoa ho etsa koporo - cyanide complexes. Sena se bohlokoa ka ho khetheha ha u roala holim'a li-substrates tse kang zinki - alloy die - castings. Zinc - alloy die - castings e sebelisoa haholo ha ho etsoa lintho tse khabisitsoeng, li-zippers le likarolo tse nyane tsa mochini. Kaha zinki - alloy e kotsing ea ho bola ka har'a litharollo tsa acidic plating, ts'ebetso ea cyanide-based copper - plating hangata e sebelisoa joalo ka mohato oa pele ho plating. The lera koporo depositi ho sebelisa cyanide - e nang le electrolyte sireletsa zinki - alloy substrate ho tloha acidic tikoloho ya dithulaganyo latelang plating, tse kang nickel plating, 'me e boetse e ntlafatsa adhesion ea nickel lera.

2. Silver Plating: Sodium cyanide e boetse e sebelisoa ka silevera ea electroplating. Li-complexes tsa silevera - cyanide li thehoa ka har'a electrolyte, e etsang hore ho be le chelete e boreleli le e khanyang ea silevera. Lintho tse entsoeng ka silevera li sebelisoa hangata indastering ea mabenyane, tlhahiso ea li-tableware, le likhokahano tsa motlakase. Ts'ebeliso ea sodium cyanide ho electroplating ea silevera e netefatsa pheletso ea boleng bo holimo, 'me lesela la silevera le na le ponahalo e ntle haholo le ho hanyetsa kutu.

3. Plato ea Zinc: Le hoja ho entsoe boiteko ba ho hlahisa mekhoa ea ho roala li-non-cyanide zinc, maemong a mang, electroplating ea zinc e thehiloeng ho cyanide e ntse e sebelisoa. Li-zinc - cyanide complexes tse entsoeng ka thuso ea sodium cyanide li fana ka matla a matle a ho lahlela 'me li lumella ho behoa ha lesela le tšoanang la zinki. Zinc plating e sebelisoa haholo bakeng sa ts'ireletso ea kutu ea likarolo tsa tšepe le tšepe, joalo ka liindasteri tsa kaho le tsa likoloi.

Mehopolo ea Ts'ireletso

Leha e na le melemo e mengata ho electroplating, sodium cyanide ke ntho e chefo haholo. E ntša khase ea hydrogen cyanide ha e kopana le asiti kapa metsi. Ka hona, mehato e tiileng ea polokeho e tlameha ho beoa litsing tsa electroplating tse sebelisang sodium cyanide:

1. Tšoaro e Nepahetseng le Polokelo: Sodium cyanide e lokela ho bolokoa sebakeng se sireletsehileng, se nang le moea o motle, hole le li-acids le mongobo. Basebetsi ba tšoarang sodium cyanide ba tlameha ho koetlisoa ka mekhoa e nepahetseng ea ho tšoara, ho kopanyelletsa le tšebeliso ea thepa ea ho itšireletsa e kang liatlana, likhalase le tšireletso ea phefumoloho.

2. Merero ea Karabelo ea Tšohanyetso: Limela tsa Electroplating li lokela ho ba le meralo e felletseng ea karabelo ea tšohanyetso haeba ho ka qhalana ka phoso kapa ho ntšoa ha sodium cyanide. Merero ena e lokela ho kenyelletsa mekhoa ea ho tlosa sebaka seo, ho fokotsa cyanide, le ho fana ka thuso ea bongaka ho basebetsi ba amehileng.

3. Tšireletso ea tikoloho: Metsi a litšila a tsoang lits'ebetsong tsa electroplating tse nang le sodium cyanide a tlameha ho ts'oaroa hantle ho tlosa cyanide pele e ntšetsoa tikolohong. Mekhoa ea phekolo e ka kenyelletsa k'hemik'hale ea oxidation, e fetolang cyanide ho metsoako e seng kotsi haholo.

Qetellong, sodium cyanide e bapala karolo ea bohlokoa indastering ea electroplating, e nolofalletsang tlhahiso ea lihlahisoa tsa boleng bo holimo, tse tšoarellang, le tse khahlehang ka mokhoa o motle. Leha ho le joalo, tšebeliso ea eona e tlameha ho laoloa ka hloko ho netefatsa polokeho ea basebetsi le tšireletso ea tikoloho. Ha theknoloji e ntse e hatela pele, ho ntse ho etsoa boiteko ba ho theha mekhoa e meng, e seng chefo e fokolang bakeng sa electroplating, empa hajoale, sodium cyanide e ntse e le karolo ea bohlokoa lits'ebetsong tse ngata tsa electroplating.
