Metsi Cooling Pulse Periodic Reverse 415V Electrolysis Power Supply
1. Molao-motheo oa motheo oa periodic reverse pulse plating
Ts'ebetsong ea pulse plating, ha hona joale ho buloa, polarization ea electrochemical ea eketseha, li-ion tsa tšepe tse haufi le sebaka sa cathode li kenngoa ka ho feletseng, 'me lesela la plating le khabisoa hantle ebile le khanyang; ha hona joale e tima, li-ion tsa ho tsoa haufi le sebaka sa cathode li khutlela mahloriso a pele. Polarization ea mahloriso e felisitsoe.
Periodic commutation pulse plating hangata e tsejoa e le double (ie bidirectional) pulse plating. E hlahisa sete ea reverse pulse current ka mor'a ho ntša sete ea pele pulse current. Nako ea ho otla ha pelo e eang pele ke nako e telele 'me nako ea ho otla ka morao e khutšoanyane. Kabo ea hona joale ea anode e sa ts'oaneng haholo e bakoang ke sekhahla sa nako e khuts'oane se tla etsa hore karolo ea convex ea lesela e qhibilihe ka matla le ho ba sephara. Sebopeho se tloaelehileng sa nako le nako sa pulse waveform se bontšitsoe ka tlase.
Likaroloana
U sebelisa ts'ebetso ea ho laola nako, tlhophiso e bonolo ebile e bonolo, 'me nako ea ts'ebetso ea polarity e ntle le e mpe ea hona joale e ka beoa ka mokhoa o ikhethileng ho latela litlhoko tsa ts'ebetso ea plating.
E na le libaka tse tharo tse sebetsang tsa ho feto-fetoha ha potoloho ea othomathike, e ntle le e mpe, le ho kheloha, 'me e ka fetola polarity ea tlhahiso ea hona joale.
Bokhabane ba periodic commutation pulse plating
1 Reverse pulse current e ntlafatsa kabo ea botenya ea koae, botenya ba ho roala bo lekana, 'me boemo bo botle.
2 Ho qhibiliha ha anode ea mokokotlo o ka morao ho etsa hore ho hlophisoa ha li-ion tsa tšepe ka holim'a cathode ho phahame ka potlako, e leng se loketseng ho sebelisoa ha sekhahla se phahameng sa maqhubu nakong ea potoloho e latelang ea cathode, 'me sekhahla se phahameng sa pulse hona joale se etsa hore lebelo la ho thehoa. nucleus ea kristale ka potlako ho feta tekanyo ea ho hōla ha kristale, kahoo Thepa e teteaneng ebile e khanyang, e nang le porosity e tlaase.
3. Reverse pulse anode stripping e fokotsa haholo ho khomarela litšila tsa lintho tse phelang (ho kenyeletsoa le brightener) ka ho roala, kahoo ho roala ho na le bohloeki bo phahameng le ho hanyetsa ka matla ho fetoha ha mebala, e leng ntho e hlahelletseng ka ho khetheha ho plating ea silevera ea cyanide.
4. The reverse pulse hona joale oxidizes ea haedrojene e nang le barbotage, e ka felisa hydrogen embrittlement (jwalo ka pulse reverse ka tlosa co-deposited hydrogen nakong electrodeposition ea palladium) kapa fokotsa khatello ea kelello ka hare.
5. Nako ea nako ea morao-rao ea pulse e boloka bokaholimo ba karolo e pentiloeng e le boemong bo sebetsang ka linako tsohle, e le hore ho ka fumanoa lera la plating le nang le matla a ho kopanya hantle.
6. Reverse pulse e thusa ho fokotsa botenya ba sebele ba lera la phallo le ho ntlafatsa katleho ea hona joale ea cathode. Ka hona, li-parameter tse nepahetseng tsa pulse li tla potlakisa le ho feta lebelo la deposition ea ho roala.
7 Ka har'a sistimi e sa lumelleng kapa e nyane ea li-additives, plating e habeli ea pulse e ka fumana seaparo se setle, se boreleli le se boreleli.
Ka lebaka leo, matšoao a ts'ebetso ea ho roala joalo ka ho hanyetsa mocheso, ho hanyetsa ho roala, ho cheselletsa, ho tiea, ho hanyetsa kutu, conductivity, ho hanyetsa ho fetoha ha mmala, le ho boreleli ho eketsehile ka mokhoa o tsotehang, 'me e ka pholosa haholo litšepe tse sa tloaelehang le tsa bohlokoa (hoo e ka bang 20% -50). %) le ho boloka li-additives (tse kang Bright silver cyanide plating ke hoo e ka bang 50% -80%).
