Madzi Kuzirala Kugunda Periodic Reverse 415V Electrolysis Power Supply

1. Mfundo yofunikira ya periodic reverse pulse plating

Mu ndondomeko ya pulse plating, pamene panopa imatsegulidwa, polarization ya electrochemical imawonjezeka, ma ion zitsulo pafupi ndi malo a cathode amaikidwa mokwanira, ndipo plating wosanjikiza ndi finely crystallized ndi yowala; pamene panopa kuzimitsidwa, ayoni kumaliseche pafupi ndi cathode dera kubwerera ndende koyamba. The ndende polarization inathetsedwa.
Periodic commutation pulse plating imadziwika kuti double (ie bidirectional) pulse plating. Imayambitsa gulu la reverse pulse current pambuyo potulutsa seti ya kugunda kwapatsogolo. Kutalika kwa kugunda kwapatsogolo ndi kwanthawi yayitali ndipo kugunda kwapambuyo kumakhala kwaufupi. Kugawidwa kwa anode komwe sikuli yunifolomu komwe kumachitika chifukwa cha kugunda kwakanthawi kochepa kumapangitsa kuti gawo lopindika la zokutira lisungunuke mwamphamvu ndikuphwanyidwa. Mawonekedwe a periodic commutation pulse waveform akuwonetsedwa pansipa.

Mawonekedwe
Pogwiritsa ntchito kuwongolera nthawi, kuyika kwake ndikosavuta komanso kosavuta, ndipo nthawi yogwira ntchito yabwino komanso yoyipa yaposachedwa imatha kukhazikitsidwa mosasamala malinga ndi zofunikira za plating.
Ili ndi zigawo zitatu zogwirira ntchito zosinthira zodziwikiratu, zabwino ndi zoyipa, ndikubwerera m'mbuyo, ndipo zimatha kusintha zokha polarity ya zomwe zimatulutsa.

Kupambana kwa periodic commutation pulse plating
1 Reverse pulse current imathandizira kugawa kwa makulidwe a zokutira, makulidwe a zokutira ndi yunifolomu, ndipo mulingo wake ndi wabwino.
2 Kusungunuka kwa anode kwa reverse pulse kumapangitsa kuti ma ayoni achitsulo pamtundu wa cathode akweze mwachangu, zomwe zimapangitsa kuti pakhale kugunda kwamphamvu kwapanthawiyo pakadutsa kachulukidwe ka cathode, ndipo kuchuluka kwamphamvu kwamphamvu kwapano kumapangitsa kupanga liwiro la phata la kristalo mofulumira kuposa kukula kwa kristalo, kotero Chophimbacho ndi chowuma komanso chowala, chokhala ndi porosity yochepa.
3. Reverse pulse anode stripping amachepetsa kwambiri kumamatira kwa zonyansa za organic (kuphatikiza chowunikira) mu zokutira, kotero kuti zokutira zimakhala ndi chiyero chambiri komanso kukana kwamphamvu kusinthika, komwe kumawonekera kwambiri mu plating ya siliva ya cyanide.
4. The n'zosiyana zimachitika panopa oxidize wa haidrojeni zili ❖ kuyanika, amene angathe kuthetsa hydrogen embrittlement (monga n'zosiyana zimachitika akhoza kuchotsa co-deposited haidrojeni pa electrodeposition wa palladium) kapena kuchepetsa nkhawa mkati.
5. The periodic reverse pulse current imasunga pamwamba pa gawo lopukutidwa kuti likhale logwira ntchito nthawi zonse, kotero kuti plating wosanjikiza ndi mphamvu yabwino yolumikizana ingapezeke.
6. Reverse pulse ndiwothandiza kuchepetsa makulidwe enieni a kusanjikizana ndikuwongolera cathode panopa. Chifukwa chake, magawo oyenera a pulse adzapititsa patsogolo kuchuluka kwa zokutira.
7 Mu plating system yomwe siyilola kapena zowonjezera pang'ono, kuyika kwapawiri kungathe kupeza zokutira zabwino, zosalala, komanso zosalala.
Zotsatira zake, zizindikiro zogwirira ntchito za ❖ kuyanika, monga kukana kutentha, kukana kuvala, kuwotcherera, kulimba, kukana dzimbiri, madulidwe, kukana kusinthika, ndi kusalala kwachulukirachulukira, ndipo zimatha kupulumutsa kwambiri zitsulo zamtengo wapatali (pafupifupi 20% -50). %) ndikusunga zowonjezera (monga Bright silver cyanide plating ndi pafupifupi 50% -80%)
