Titanium Anode rau galvanic deposition

Titanium anode rau galvanic deposition

Nyob rau hauv lub tshav pob ntawm galvanic deposition ntawm cov hlau rau kev lag luam los yog pej xeem siv, muaj ntau yam possibilities ntawm kev siv rau activatedTitaniumRaws li anode, hloov cov soluble anodes.

Tam sim no tau ntau xyoo nws tau raug siv los ua ib qho kev pabcuam anode kom ruaj khov ntawm Nickel concentration hauv Watt lossis Sulfamate da dej thiab hauv cov kua qaub tooj liab plating da dej.

Kev siv ncaj qha, hloov thiab nrog tib qhov kev ua yeeb yam ntawm platinised Titanium, ntau kim dua, hauv cov da dej kub plating, Platinum plating, Rhodium plating thiab Nickel / Palladium plating.

Tsis tas li ntawd nyob rau hauv cov dej tso dej tsis ntev los no, piv txwv li Zinc / Nickel hom, activated Titanium yog siv tshwj xeeb.

Nyob rau hauv niaj hnub zoo nkauj Chrome plating da dej los ntawm Sulphates raws li trivalent Chromium, kev siv ntawm no anode yog yuav tsum tau, nrog ib tug txheej tshwj xeeb uas tsim los txo kom tsawg kawg nkaus tsim ntawm hexavalent Chromium uas cuam tshuam tsis zoo rau kev ua tau zoo thiab qhov zoo ntawm Chromium deposited.

Nyob rau hauv lub hard Chrome plating nrog hexavalent Chrome, activated Titanium yog siv nyob rau hauv cov ntaub ntawv thaum ib tug tshwj xeeb anode geometry yuav tsum, uas cov classic anodes nyob rau hauv Lead alloy tsis tuaj yeem tsim dua. Tab sis koj yuav tsum tau ua tib zoo xav txog kev siv cov Lead anodes kom rov oxidate qhov tsis xav tau trivalent Chrome uas ua rau ntawm cathode, qhov tseeb no cov tshuaj tiv thaiv tsis yog tsim los ntawm activated Titanium vim nws tsis tshua muaj peev xwm anode.

Peb tuaj yeem tsim txhua hom txheej txheej tsim nyog rau txhua tus txheej txheem thiab nws tsim cov anodes raws li tus neeg siv khoom kos duab lossis nws tawm tswv yim nws cov kev daws teeb meem. Nws tseem tuaj yeem qhib anodes uas tsim ncaj qha los ntawm tus neeg siv khoom.

Titanium anode rau Electro galvanizing

Cov txheej txheem no yog diffused nyob rau hauv cov hlau thiab hlau kev lag luam rau zus tau tej cov electrolytically zinc-plated hlau kauj, los ntawm ib tug maj mam acid Zinc sulphate tov.

Lub kauj, nrog qhov sib txawv ntawm qhov dav ntawm ib ncig ntawm 600 mus rau 1400 hli, sai sai mus los ntawm cov kab hluav taws xob electrolytic nyob rau hauv cathodic polarisation. Anodes tuaj yeem ua rau cov zinc soluble, Lead lossis activated Titanium. Cov tom kawg muaj qhov zoo heev piv nrog rau lwm tus raws li nws ruaj khov hauv qhov loj, sib dua, tsis muaj kuab paug rau hauv chav da dej, nws tsis tas yuav tsum muaj kev saib xyuas thiab piv rau Lead nws tso cai rau kev txuag hluav taws xob, ua tsaug rau nws qhov qis dua rau cov pa tawm.

Vim tias muaj kev sib cuag ntawm cov coil thiab anode, tshwm sim los ntawm qhov sib thooj heev (< 1 cm) uas cov txheej txheem xav tau, luv Circuit Court tshwm sim uas ua rau muaj kev puas tsuaj uas cuam tshuam qhov kev ua tau zoo thiab lub sijhawm ntawm txheej txheej.

Peb tau tsim cov txheej txheem uas tshwj xeeb tshaj yog tiv taus rau hom kab mob no nrog kev tiv thaiv kev tiv thaiv ntawm titanium puag uas, tom qab lub hauv paus polarity inversions tshwm sim los ntawm luv luv circuits, poob lub passivation thiab tiv thaiv TiO2 txheej thiab nyhav corroded, nrog rau tom ntej detachment. ntawm txheej txheej.

Cov txheej txheem tshwj xeeb no, nrog Iridium, Tantalum thiab Tin Oxide tshwj xeeb yog compact thiab nws tso cai rau kev sib cais zoo heev ntawm Titanium puag los ntawm kev daws thiab yog li muaj kev cuam tshuam los ntawm kev tawm tsam ntawm cov kua qaub ntawm cov tshuaj nws tus kheej.

Titanium anode rau Electrotinning

Cov txheej txheem no zoo ib yam li electrotinning rau ntau yam, nyob rau hauv cov ntaub ntawv no cov ntaub ntawv uas yog deposited yog Tin.

Nyob rau hauv feem ntau cov nroj tsuag cov soluble tin anode yog siv, whereas lub insoluble activated Titanium anode tsuas yog tso rau hauv ib los yog ob lub hlwb, nrog rau lub hom phiaj ntawm rebalancing lub concentration ntawm Tin nyob rau hauv cov tshuaj, uas muaj ib tug nyiam ua rau kom lub qis cathode efficiency piv rau. cov anode.

Nyob rau hauv ob peb xyoos dhau los, ib tug system tau tsim nyob rau hauv uas tsuas yog insoluble anodes yog siv, whereas txhuas yog yaj nyob rau hauv ib tug tshwj xeeb yaj.

Muab qhov aggressiveness ntawm cov tshuaj tsim los ntawm methanesulfonic (MSA) thiab phenolsulfonic acid (PSA), uas zoo li yuav ua rau kom cov kev ceev ntawm Iridium Oxide thiab ntxiv rau cov nyiam los tsim ib co "overcoatings" ntawm passivating Lead Oxide ntawm lub anodes, muaj cov yuav tsum tau tsim ib tug txheej txheej formulation thiab ib tug tshwj xeeb kev kho mob rau lub hauv paus roughness uas hindered lub overcoating tuav.

Peb tuaj yeem muab ob qho kev daws teeb meem, ob qho tib si rau MSA thiab PSA rooj plaub.

Tsis tas li ntawd nws tsim cov anodes raws li tus neeg siv khoom kos duab lossis nws tsuas yog muab cov kev pabcuam rov txheej rau ntawm cov anodes hnav.
