1. Siv qhov xav tau ntawmtitanium anode
Raws li qhov xav tau tiag tiag ntawm cov neeg siv khoom, thaum cov txheej txheem tooj liab plating yog hloov los ntawm phosphor tooj liab pob rau titanium anode, qhov kev thov tseem ceeb yog kom ua tau zoo thiab ruaj khov kho cov electroplating uniformity, uas yuav ua rau kev txhim kho zoo; Qhov thib ob, nws yuav tsum tau ua kom qhov zoo ntawm titanium anode ruaj khov thiab tuaj yeem ncav cuag qhov kev cia siab ntawm lub neej kev pab cuam thiab ruaj khov additive noj theem nyob rau lub sij hawm no kom paub meej tias cov nqi khiav hauj lwm tswj tau. Yog li ntawd, hauv cov ntsiab lus, cov kev cai tseem ceeb yog raws li hauv qab no: zoo heev electroplating uniformity, ruaj khov kev pab cuam lub neej, thiab controllable additive noj theem.
Rau cov tuam txhab anode, yuav ua li cas txhais cov neeg xav tau kev pab rau hauv cov kev cai sab hauv rau cov khoom tsim yog qhov tseem ceeb tshaj plaws rau cov tuam txhab anode los kawm thiab muab kev txhawb nqa sib xws. titanium substrate thiab txheej txheej ua rau feem ntau ntawm cov qauv titanium anode. Raws li cov kev cai tshwj xeeb, cov kev xav tau ntawm electroplating uniformity feem ntau yog txiav txim siab los ntawm cov neeg kho tshuab tsim ntawm titanium substrate, thaum lwm qhov ob qhov yuav tsum tau muaj feem cuam tshuam nrog kev tsim txheej txheej.
2. Tsim cov titanium anode paug uniformity
Lub ntsiab mechanical tsim ntawm titanium anode yuav tsum tau sib txuam nrog cov khoom siv, thiab cov khoom tseem ceeb yog ua tiav los ntawm cov khoom siv. Cov chaw tsim tshuaj paus anode yuav tsum muab cov lus qhia sib xws thiab kev txhawb nqa ntawm yuav ua li cas txhawm rau txhim kho tus qauv ntawm titanium anode tawm kev sib xws, feem ntau los ntawm cov hauv qab no.
i. Teeb meem tiv thaiv
Nyob rau hauv kev tsim ntawm titanium anode tawm uniformity, thawj lub ntsiab lus uas yuav tsum tau muaj kev txhawj xeeb yog lub resistivity ntawm titanium cov ntaub ntawv. Lub resistivity ntawm ntshiab titanium yog hais txog 0.47 μ Ω · m, ze rau 30 lub sij hawm ntawm ntshiab tooj liab nyob rau hauv tib yam mob. Thaum siv lub pob tooj liab phosphor, lub anode tam sim no tau qhia los ntawm sab sauv ntawm lub pob tawb titanium, thiab tom qab ntawd ua los ntawm cov pob tooj liab hauv tag nrho cov anode (hauv qhov tseem ceeb, nws tuaj yeem txiav txim siab tias tam sim no yog ua los ntawm tooj liab). Yog li ntawd, qhov sib txawv conductivity ntawm sab sauv thiab sab qis yog me me, uas tuaj yeem tsis quav ntsej. Thaum siv titanium anode, qhov conductivity ntawm titanium kuj tsis zoo, tshwj xeeb tshaj yog thaum titanium anode ua haujlwm ntawm qhov ceev tam sim no, thiab tam sim no kis tau los ntawm sab sauv ntawm anode mus rau sab qis, qhov kev tiv thaiv ntawm titanium nws tus kheej. yuav ua rau muaj qhov txo qis hauv qhov voltage ntawm sab saum toj mus rau hauv qab. Nyob rau hauv txoj kev no, qhov tso tawm tam sim no ceev nyob rau hauv qab ntawm titanium anode yuav txo qis tshaj qhov nyob rau sab saum toj ntawm titanium anode.
Hauv kev tsim anode, thawj qhov kev txiav txim siab yog yuav ua li cas txo qhov poob qis los ntawm kev ua haujlwm ntev ntawm titanium cov ntaub ntawv. Nws tuaj yeem ua kom zoo tshaj plaws los ntawm ob qho hauv qab no: ① txo cov kev tiv thaiv kev tiv thaiv, siv cov ntaub ntawv dav dua thiab tuab dua titanium rau kev ua haujlwm tam sim no, lossis siv cov khoom siv titanium tooj liab los pab tam sim no; ② Scatter cov ntsiab lus tam sim no, thiab teeb tsa ntau lub ntsiab lus tam sim no ntawm qhov chaw anode kom tsis txhob kis tau tus mob ntev.
ii. Lub hom phiaj optimization ntawm anode substrate hom
Tam sim no, hauv kev tsim ntawm titanium anode, muaj ob hom anode substrate: ib qho yog titanium phaj, thiab lwm yam yog titanium mesh.
Titanium mesh yog ua los ntawm titanium phaj los ntawm kev xuas nrig ntaus thiab kos duab, thiab nws cov txiaj ntsig tseem ceeb yog nyob rau hauv ob yam: ua ntej, piv nrog titanium phaj, titanium cov khoom siv tau txais kev cawmdim; Qhov thib ob, vim tias cov titanium mesh feem ntau yog coated rau ob sab, txawm tias nws tsis fim sab nraub qaum ntawm cov khoom, vim tias cov khoom siv mesh yog cov qauv hollow, cov txheej sab nraub qaum kuj tseem tuaj yeem koom nrog hauv qhov paug tawm, yog li cov khoom siv hluav taws xob zoo. tag nrho cov mesh anode loj dua li ntawm titanium phaj, uas tuaj yeem txo qhov ceev tam sim no raws li qhov tseeb anode ua haujlwm. Lub zog txhua yam ntawm cov reticulated anode feem ntau yog qhov phem dua, thiab nws cov resistivity siab dua li ntawm cov phaj anode. Txhawm rau daws cov teeb meem saum toj no, qhov flatness thiab paug tsis sib xws ntawm titanium mesh anode tuaj yeem txhim kho tau zoo los ntawm kev tsim cov thav duab tsim nyog thiab optimizing txoj hauj lwm ntawm cov pob qij txha.
Qhov zoo tshaj plaws ntawm kev siv lub phaj anode yog tias lub substrate ntawm phaj anode tuaj yeem rov qab siv dua. Tom qab cov txheej txheem anode ua tsis tiav, cov txheej txheej seem tuaj yeem raug stripped, substrate nto tuaj yeem ntxuav kom huv si, thiab tom qab ntawd cov txheej tuaj yeem rov ua dua. Nyob rau hauv txoj kev no, tus nqi siv mus sij hawm ntev tuaj yeem txuag tau rau qee yam hauv kev siv yav tom ntej ntawm lub anode (txawm hais tias qhov kev nqis peev ib zaug yuav loj dua me ntsis). Ntawm qhov tod tes, lub thickness ntawm phaj anode substrate feem ntau yog 2 hli thiab 3 hli, thaum lub mesh anode feem ntau haum rau kos los ntawm 1 hli titanium phaj (muaj ib tug hollow nyob rau hauv nruab nrab), yog li cov conductivity ntawm phaj anode yog. zoo dua li ntawm mesh anode. Lub flatness kuj yuav zoo dua, thiab phaj anode tus txheeb ze mechanical zog yog siab dua li ntawm cov mesh anode. Txawm li cas los xij, qhov no tsis txhais tau hais tias qhov sib txawv ntawm cov phaj anode zoo dua li cov mesh anode. Nyob rau hauv sib piv, tag nrho cov neeg kho tshuab tsim ntawm phaj anode yog yooj yim dua li ntawm cov mesh anode (nrog ib tug ncej). Txawm li cas los xij, tseem muaj chaw rau kev ua kom zoo dua ntawm kev faib cov phaj anode tam sim no nkag mus rau cov ntsiab lus yog tias nws yuav tsum tau hloov mus rau cov kev xav tau ntawm electroplating ntau dua.
