Yiziphi izici ngokuvamile ezithinta i-sodium cyanide copper plating?

I-sodium cyanide I-Copper plating kungokwesiko I-Electroplating indlela esetshenziswa kabanzi ezimbonini ezahlukahlukene, ikakhulukazi kwezokukhiqiza ubucwebe be-elekthronikhi. Lolu hlelo lubandakanya ukusetshenziswa kwe-a Isixazululo se-Pating esebenza njenge-ejenti eyinkimbinkimbi, ngokuyinhloko eyakhiwe ama-ion ethusi kanye nenani elithile I-cyanide yamahhala, konke kugcinwa endaweni ene-alkaline enamandla. Nakuba le ndlela ibonakale iphumelela, izici ezimbalwa zingathonya kakhulu izinga lomkhiqizo wokugcina. Ukuqonda lezi zici kubalulekile ekuthuthukiseni inqubo yokucwenga kanye nokuqinisekisa imiphumela yekhwalithi ephezulu.

1.Ukulawula Ukushisa

Enye yezinto ezibaluleke kakhulu ezithinta I-sodium cyanide i-copper plating yizinga lokushisa lesisombululo se-plating. Izinga lokushisa elilungile lale nqubo ngokuvamile liphakathi kuka-50°C kuya ku-65°C. Ngaphakathi kwalolu hlu, ukusebenza kahle kwamanje kwe-cathode kukhuliswa, okuholela ekufakweni okufanayo kanye nediphozithi yethusi ephezulu.

Uma izinga lokushisa liphansi kakhulu, ukusebenza kahle kwamanje kwe-cathode kuyehla, okuholela ekhwalithini yokucwenga empofu. Ngakolunye uhlangothi, amazinga okushisa aphakeme ngokweqile angaholela ekuboleni kwesisombululo sokucwenga, kukhiqizwe imikhiqizo engathandeki efana ne-sodium carbonate ne-ammonia. Le mikhiqizo ingathinta kabi inqubo yokucwenga kanye nekhwalithi yokunamathela kokugcina. Ngakho-ke, ukugcina izinga lokushisa elifanele kubalulekile ukuze kuzuzwe imiphumela efanelekile yokucwenga.

2. Ukuphathwa Kwamanje Kokuminyana

Ukuminyana kwamanje kungenye into ebalulekile ethonya ukusebenza kahle kanye nekhwalithi ye I-Sodium Cyanide i-copper Plating. Ukuminyana kwamanje kubhekisela enanini lamandla kagesi asetshenziswa endaweni ngayinye yeyunithi ye-cathode. Ukwandisa ukuminyana kwamanje kungaholela ekunciphiseni kokubili ukusebenza kahle kwamanje kwe-cathode ne-anode.

Lapho ukuminyana kwamanje kwe-anode kuba phezulu kakhulu, kungaholela ekudlulisweni kwe-anode, isimo lapho i-anode ingasabeli kahle futhi ivimbe inqubo yokucwenga. Ukuze unciphise le nkinga, ukusetshenziswa kwamandla okushintshashintsha ngezikhathi ezithile kungaba yinzuzo. Le nqubo ivumela ukukhuphuka okulawulwayo kokuminyana kwamanje, okuvumela ukuphathwa okungcono kwenqubo yokucwenga kanye nekhwalithi yokunamathela ethuthukisiwe.

3. Iqhaza Le-Cyclic Reverses Power Supply

Ukuqaliswa kokunikezwa kwamandla okubuyisela emuva umjikelezo kunqubo ye-electroplating kungathuthukisa kakhulu ikhwalithi ye-copper coating. Le ndlela ivumela ukulungiswa kwe-anode yamanje, okungaholela ekunciphiseni kwe-porosity yokugqoka. Ukumboza okuncane okunezimbotshana kuvame ukufiseleka kakhulu, njengoba kunikeza isivikelo esingcono ekugqwaleni futhi kuthuthukise ukuqina kukonke kwendawo ecwecwe.

Ukwengeza, ukusetshenziswa kwamandla okubuyisela umjikelezo we-cyclic kungathuthukisa ukusebenza kweleveli yesisombululo sokucwenga. Ngokungeza inani elincane lokukhanyisa usawoti wensimbi kwisisombululo, kungenzeka ukufeza ukugqoka kwethusi okukhanyayo okunezici ezinhle kakhulu zokulinganisa. Le nhlanganisela yamasu ingaholela ekuqedeni kwekhwalithi ephezulu okuhlangabezana nezidingo eziqinile zezinhlelo zokusebenza ezahlukahlukene.

4. Ukungcola Nokuphatha Kwakho

Ukuba khona kokungcola kusixazululo se-plating kungaba nomthelela omubi kwikhwalithi yediphozi yethusi. Okunye kokungcola okuvame ukuhlangana nakho i-sodium cyanide i-copper plating yi-carbonate. Uma okuqukethwe kwe-carbonate kudlula u-70g/L, kubalulekile ukukususa ukuze kugcinwe ubuqotho benqubo yokucwenga.

Indlela ejwayelekile yokukhipha i-carbonate eyeqile ihlanganisa ukupholisa isixazululo se-plating sibe ngaphansi kuka-0°C, okuvumela i-carbonate ukuthi icwebeze ngokwemvelo. Nakuba le ndlela iqondile futhi isebenza kahle, kubalulekile ukuqaphela ukuthi cishe i-10% kasawoti wensimbi ingase ilahleke phakathi nenqubo ye-crystallization. Ngakho-ke, kufanele kucatshangelwe ngokucophelela abaphathi bokungcola ukuze kuqinisekiswe ukuthi isixazululo sokucwenga sihlala sisebenza kahle nokuthi ikhwalithi yomkhiqizo wokugcina ayiphazamiseki.

Isiphetho

I-sodium cyanide copper plating iyindlela esetshenziswa kakhulu ye-electroplating enikeza izinzuzo eziningi ngokuya ngokusebenza kahle kanye nekhwalithi. Kodwa-ke, impumelelo yale nqubo incike kakhulu ezintweni ezimbalwa ezibalulekile, okuhlanganisa ukulawulwa kwezinga lokushisa, ukuphathwa kwamanje kokuminyana, ukusetshenziswa kwamandla okuhlehlisa umjikelezo, kanye nokuphathwa kokungcola.

Ngokuqonda nokwandisa lezi zici, abakhiqizi bangathuthukisa ikhwalithi yezingubo zabo zethusi, baqinisekise ukuthi bahlangabezana nezidingo ezinzima zezimboni ezihlukahlukene. Njengoba ubuchwepheshe buqhubeka buthuthuka, ucwaningo oluqhubekayo kanye nentuthuko emkhakheni we-electroplating cishe kuzoholela ekuthuthukisweni okwengeziwe kwenqubo yokucwenga yethusi ye-sodium cyanide, kuvula indlela yekhwalithi ephezulu kakhulu nezindlela zokukhiqiza ezisebenza kahle kakhulu.

Kafushane, ukuphathwa ngokucophelela kwezinga lokushisa, ukuminyana kwamanje, amasu okunikezwa kwamandla kagesi, namazinga okungcola kubalulekile ukuze kuzuzwe imiphumela emihle ekucwecweni kwethusi kwe-sodium cyanide. Ngokugxila kulezi zici ezibalulekile, abakhiqizi bangaqinisekisa ukuthi izinqubo zabo ze-electroplating zikhiqiza izembatho zethusi ezisezingeni eliphezulu, ezihlala isikhathi eside, nezithembekile ezihlangabezana nezidingo zamakhasimende abo.
