I-Water Cooling Pulse Periodic Reverse 415V Electrolysis Power Supply
1. Umgomo oyisisekelo we-periodic reverse pulse plating
Enkambweni ye-pulse plating, lapho i-current ivuliwe, i-electrochemical polarization iyanda, i-ion yensimbi eduze nendawo ye-cathode ifakwe ngokugcwele, futhi ungqimba lokucwenga lucwebezeliswe kahle futhi lugqamile; lapho i-current ivaliwe, ama-ion okukhipha eduze nendawo ye-cathode abuyela ekugxilweni kokuqala. I-polarization yokuhlushwa iqedwa.
I-Periodic commutation pulse plating ngokuvamile kwaziwa ngokuthi i-pulse plating ephindwe kabili (okungukuthi, i-bidirectional). Yethula isethi ye-reverse pulse current ngemva kokukhipha isethi yamanje yokushaya eya phambili. Ubude be-pulse eya phambili yinde futhi ubude be-pulse obubuyela emuva bufushane. Ukusatshalaliswa kwamanje kwe-anode engalingani kakhulu okubangelwa i-pulse ehlehlayo yesikhathi esifushane kuzobangela ingxenye ye-convex ye-coating ukuthi incibilike ngokuqinile futhi ibe isicaba. Ukushintshwa kwe-wave wave okujwayelekile ngezikhathi ezithile kuboniswa ngezansi.
Izici
Ngokusebenzisa umsebenzi wokulawula isikhathi, ukulungiselelwa kulula futhi kulula, futhi isikhathi sokusebenza se-polarity yamanje enhle nesibi singasethwa ngokungafanele ngokuvumelana nezidingo zenqubo yokucwenga.
Inezimo ezintathu zokusebenza zokushintshwa komjikelezo okuzenzakalelayo, okuhle nokubi, kanye nokuhlehla, futhi ingashintsha ngokuzenzakalelayo i-polarity yokuphumayo kwamanje.
Ukuphakama kwe-periodic commutation pulse plating
1 I-Reverse pulse current ithuthukisa ukusatshalaliswa kogqinsi kwento enamathelayo, ukujiya kwento enamathelayo kuyafana, futhi ukulevelina kuhle.
2 Ukuqedwa kwe-anode kwe-reverse pulse kwenza ukuhlangana kwama-ion ensimbi endaweni ye-cathode kukhuphuke ngokushesha, okuvumela ukusetshenziswa kwe-high pulse yamanje ukuminyana kumjikelezo we-cathode olandelayo, futhi ukuminyana okuphezulu kwe-pulse kwamanje kwenza isivinini sokwakheka i-crystal nucleus ngokushesha kunezinga lokukhula kwekristalu, ngakho-ke I-coating iminyene futhi ikhanya, ine-porosity ephansi.
3. I-reverse pulse anode stripping kunciphisa kakhulu ukunamathela kokungcola okuphilayo (okuhlanganisa i-brightener) ekugqokeni, ngakho-ke ukugqoka kunokuhlanzeka okuphezulu kanye nokumelana okuqinile nokushintsha umbala, okugqame kakhulu ekufakweni kwesiliva kwe-cyanide.
4. I-Reverse pulse current i-oxidize i-hydrogen equkethwe ku-coating, engaqeda i-hydrogen embrittlement (njengokungathi i-reverse pulse ingasusa i-hydrogen e-co-deposited ngesikhathi se-electrodeposition ye-palladium) noma inciphise ukucindezeleka kwangaphakathi.
5. I-periodic reverse pulse current igcina ingaphezulu lengxenye epuletiwe isesimweni esisebenzayo ngaso sonke isikhathi, ukuze kutholakale ungqimba lokucwenga olunamandla okubopha okuhle.
6. I-Reverse pulse iyasiza ukunciphisa ukushuba kwangempela kwesendlalelo sokusabalalisa futhi ithuthukise ukusebenza kahle kwamanje kwe-cathode. Ngakho-ke, imingcele efanele ye-pulse izoqhubekisela phambili ukusheshisa izinga lokubekwa kwe-coating.
7 Ohlelweni lokucwenga olungakuvumeli noma inani elincane lezithasiselo, i-pulse plating ephindwe kabili ingathola ukunamathela okuhle, okubushelelezi, nokushelelayo.
Ngenxa yalokho, izinkomba zokusebenza ze-coating ezifana nokumelana nokushisa, ukumelana nokugqoka, ukushisela, ukuqina, ukumelana nokugqwala, ukuguquguquka, ukumelana nokuguquguquka, nokushelela kuye kwanda kakhulu, futhi kungasindisa kakhulu izinsimbi ezingavamile neziyigugu (cishe 20% -50). %) bese ulondoloza izithasiselo (ezifana ne-Bright silver cyanide plating cishe ngo-50% -80%)
