Titanium anode rau tooj liab rov qab los ntawm etching tov

Ir-Ta titanium anode yog ib hom sib xyaw hlau oxide (MMO) coated titanium anode uas yog siv rau hauv ntau yam kev siv hluav taws xob xws li electroplating, dej kho, thiab kev tiv thaiv cathodic.

"Ir" sawv cev rau Iridium, "Ta" sawv cev rau Tantalum, thiab cov anode yog ua los ntawm titanium ua cov khoom siv substrate. Lub anode yog coated nrog ib txheej ntawm tov-hlau oxide uas muaj ob qho tib si iridium thiab tantalum oxides. MMO txheej txhim kho cov anode tsis kam rau corrosion thiab txhim kho nws cov khoom electrocatalytic.

Nws yog feem ntau siv nyob rau hauv hnyav thiab corrosive ib puag ncig xws li seawater los yog acidic daws, vim lawv siab tsis kam mus corrosion. Lawv muaj lub neej ntev thiab tuaj yeem ua haujlwm tau zoo rau lub sijhawm ntev yam tsis xav tau kev saib xyuas lossis hloov pauv.

Nws feem ntau yuav siv tau rau tooj liab rov qab los ntawm etching tov, raws li tau tham ua ntej. Ir-Ta txheej ntawm titanium anode txhim kho nws cov khoom electrocatalytic, uas ua rau cov tshuaj tiv thaiv ntawm cov tshuaj etching thiab tooj liab tau zoo.

Kev piav qhia ntawm Titanium anode rau tooj liab rov qab los ntawm etching tov

1.Application cheeb tsam: Thaum lub sij hawm tsim cov txheej txheem ntawm PCB kev lag luam, ib tug loj npaum li cas ntawm micro-etching tov, etching tov, tooj liab nitrate thiab lwm yam tooj liab uas muaj ntau concentrations yog tsim.

2. Daim ntawv thov system:

3. Tam sim no ceev: (200-400) A / m2

4. Lub neej ua haujlwm: 12-24 hli

5. Txheej txheem khiav:

A. Micro-etching kua (Cu2SO4 + H2O2) Oxygen-breaking electrolytic cell (decomposing H2O2) Electrodeposited tooj liab

B. Alkaline etching solution Extraction txheej txheem tooj liab sulfate + sulfuric acid

C. Acid etching solution Ion membrane electrolysis (tooj liab deposition) Tail gas treatment (absorption of chlorine gas)

6. Electrochemical kev ua tau zoo thiab kev sim lub neej (siv tus qauv HG / T2471-2007 Q / CLTN-2012)

7. Khoom siv keeb kwm yav dhau thiab kev taw qhia:

Thaum lub sij hawm tsim cov txheej txheem ntawm PCB kev lag luam, ib tug loj npaum li cas ntawm micro-etching tov, etching tov, tooj liab nitrate thiab lwm yam hlau uas muaj ntau ntau ntawm tooj liab thiab lwm yam hlau yog tsim. Tus nqi rov ua dua tshiab yog siab, thiab qee qhov me me ntawm tooj liab hnyav hlau kuj tseem muaj nyob hauv cov dej khib nyiab. Ntawm qhov tod tes, nws ua rau muaj kev puas tsuaj loj, thiab ntawm qhov tod tes, cov hlau hnyav xau mus rau hauv av thiab dej tom qab tso tawm, uas yuav ua rau muaj kuab paug loj thiab ua rau muaj kev puas tsuaj rau ib puag ncig ntuj uas peb nyob thiab peb tus kheej noj qab haus huv. .1) Micro etching daws

Micro-etching tov suav nrog sodium persulfate / sulfuric acid system thiab hydrogen peroxide / sulfuric acid system. Nyob rau hauv xyoo tas los no, nws tau dav siv nyob rau hauv PCB nto kho txheej txheem, xws li: PTH txheej txheem, electroplating txheej txheem, puab txheej pretreatment, ntsuab roj ua ntej ua, OSP ua thiab lwm yam ntau lawm kab, ncaj electrolysis yuav ua puas lub anode txheej.

2) Etching tov

Thaum lub sij hawm lub rooj tsav xwm hluav taws xob (PCB) etching txheej txheem, cov ntsiab lus tooj liab hauv etchant maj mam nce. Yuav kom ua tiav qhov zoo tshaj plaws etching nyhuv, cov tshuaj etching yuav tsum muaj 120 mus rau 180 grams ntawm tooj liab thiab cov nqi sib xws ntawm etching ntsev (NH4CI) thiab ammonia (NH3) ib liter ntawm etching tov. Lub etching tov regeneration voj voog system yog acidic thiab alkaline. Ob lub tshuab tuaj yeem muab faib ua txoj kev rho tawm thiab ncaj qha electrolytic txoj kev. Ib tug loj npaum li cas tom qab siv etching tov uas yuav tsum tau muab tshem tawm yuav txo tau thiab regenerated rau hauv ib tug reusable etching tov. Yog li ntawd, qhov tso tawm ntawm cov kua dej pov tseg tuaj yeem txo qis, cov nqi rov qab tuaj yeem txo tus nqi tsim khoom, thiab cov khoom siv hluav taws xob zoo electrolytic tooj liab tuaj yeem raug rho tawm.

Qhov zoo ntawm titanium anode rau tooj liab rov qab los ntawm etching tov

1. 1. Kev ua haujlwm siab rau corrosion: Ir-Ta txheej ntawm titanium anode txhim kho nws cov kev tiv thaiv corrosion, txawm nyob rau hauv ib puag ncig hnyav tshuaj. Qhov no txhais tau hais tias cov anode tuaj yeem tiv taus ntev ntev rau cov tshuaj etching yam tsis muaj degrading los yog paug cov txheej txheem tooj liab rov qab.

2. 2. Kev ua kom zoo tooj liab rov qab: Cov khoom siv electrocatalytic ntawm Ir-Ta txheej txhim kho kev ua tau zoo thiab kev ua tau zoo ntawm cov txheej txheem tooj liab rov qab, uas tuaj yeem ua rau muaj txiaj ntsig ntau dua thiab cov nqi qis dua.

3. 3. Lub neej ntev: MMO coated titanium anodes muaj lub neej ntev, uas txhais tau tias lawv tuaj yeem siv rau ntau lub voj voog ntawm cov txheej txheem tooj liab ua ntej yuav tsum tau hloov.

4. 4. Kev saib xyuas tsis tshua muaj: Ir-Ta titanium anodes yuav tsum tau saib xyuas me ntsis lossis tu, uas tuaj yeem pab txo cov nqi khiav haujlwm.

Zuag qhia tag nrho, nws yog ib qho kev txhim khu kev qha thiab muaj txiaj ntsig zoo rau tooj liab rov qab los ntawm cov tshuaj etching vim lawv cov kev tiv thaiv siab rau corrosion, muaj zog electrocatalytic zog, lub neej ntev, thiab kev saib xyuas tsis tshua muaj.
