Titanium lub ntuj tsis kam rau cov tshuaj tiv thaiv:
Hauv nws lub xeev ntshiab, titanium yog cov hlau tsis tshua muaj zog. Txawm li cas los xij, zoo kawg li, thaum nws los rau hauv kev sib cuag nrog cov pa, cov yeeb yaj kiab oxide tuab tam sim ntawd ua rau ntawm nws qhov chaw. Lub ntsiab tseem ceeb ntawm zaj duab xis yog titanium dioxide (TiO₂). Nws yog cov oxide zaj duab xis uas muab titanium nws zoo heev rau cov tshuaj tiv thaiv, zoo tiv thaiv ntxiv tshuaj tiv thaiv nrog ntau lub ntsiab. Qhov no yog vim li cas titanium anodes tseem tuaj yeem ua tau zoo tshaj plaws hauv kev lag luam hnyav heev. Tau kawg, thaum titanium muaj zog tiv thaiv cov tshuaj tiv thaiv, nws tsis yog invincible. Nyob rau hauv qhov kub thiab txias los yog ib puag ncig tshuaj lom neeg, nws tseem tuaj yeem cuam tshuam nrog qee yam khoom. Tom ntej no, peb yuav tshawb xyuas ntxiv cov yam ntxwv ntawm cov tshuaj tiv thaiv no thiab lawv cov kev cuam tshuam ntawm titanium anode thev naus laus zis hauv kev siv tswv yim.
Cov tshuaj tiv thaiv ntawm titanium nrog oxygen (O₂):
Nyob rau hauv chav tsev kub, titanium reacts nrog oxygen los tsim titanium dioxide (TiO₂). Cov oxide zaj duab xis no nthuav tawm kev ruaj ntseg zoo, yog li muab titanium superior corrosion kuj. Cov yam ntxwv no tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov ntawm titanium anodes, ua kom lawv lub sij hawm ntev -lub sij hawm durability nyob rau hauv kev lag luam xws li electrolytic hydrogen ntau lawm thiab dej kho, thiab tswj lawv stability txawm nyob rau hauv ib puag ncig raug corrosive hais. Cov tshuaj tiv thaiv no tsis yog tsuas yog tso lub hauv paus rau titanium qhov kev tiv thaiv corrosion tab sis kuj yog tus yuam sij rau kev siv dav dav ntawm titanium anodes nyob rau hauv ib puag ncig hnyav.
Titanium reacts nrog nitrogen (N₂) ntawm qhov kub thiab txias los tsim titanium nitride (TiN). Cov khoom siv no muaj cov tawv tawv zoo heev thiab hnav tsis kam, ua rau nws siv dav hauv txheej txheej txheej txheem. Nws yog ib qho tsim nyog sau cia tias qhov tshuaj tiv thaiv no tsis tshua muaj tshwm sim nyob rau hauv feem ntau cov ntawv thov kev lag luam ntawm titanium anodes vim tias qhov ntsuas kub ntawm cov tshuaj tiv thaiv nyob deb ntawm cov xwm txheej uas yuav tsum tau muaj rau kev tsim titanium nitride.
Titanium tsis nquag hnov mob nrog hydrogen. Txawm li cas los xij, thaum kub siab, titanium tuaj yeem nqus tau hydrogen los ua titanium hydride (TiH₂). Cov tshuaj tiv thaiv no ua rau titanium ua nkig thiab tawv, txo nws cov thawj lub zog thiab ua rau tsis ua haujlwm thaum siv. Hmoov zoo, cov kev ua haujlwm raug cai hauv kev lag luam xws li electroplating thiab kev kho dej feem ntau tsis txaus los ua rau cov tshuaj tiv thaiv no. Nyob rau hauv cov txheej txheem electrolytic hydrogen ntau lawm, kev tswj qhov kub thiab txias yog qhov tseem ceeb heev; Yog li ntawd, xaiv titanium anodes thiab siv lawv nyob rau hauv kev tswj kom zoo tuaj yeem ua kom muaj kev nyab xeeb thiab zam cov teeb meem tshwm sim los ntawm embrittlement.
Titanium reacts hnyav nrog halogens (F₂, Cl₂, Br₂, I₂), xws li fluorine, chlorine, thiab bromine, tsim titanium halides. Cov tshuaj tiv thaiv no yog tus cwj pwm los ntawm lawv qhov ntsuas kub qis, uas yog qhov tseem ceeb tshwj xeeb hauv qee yam kev siv electrochemical. Piv txwv li, nyob rau hauv chlor-alkali ntau lawm, thaum siv titanium anodes, cov tshuaj tiv thaiv ntawm titanium thiab chlorine yuav tsum tau ua tib zoo saib xyuas kom ruaj ntseg thiab durability ntawm lub anode. Cov tshuaj tiv thaiv no ua rau titanium tetrachloride (TiCl₄), uas yog volatile thiab yuav tsum tau tiv thaiv thaum electrolysis. Txhawm rau kom muaj kev ruaj ntseg ntawm titanium anodes hauv chlorine- thaj chaw nplua nuj, txheej txheej tshwj xeeb tuaj yeem siv los kho cov anodes, txo qhov tshwm sim ntawm cov tshuaj tiv thaiv no.
Titanium Reaction nrog Acids: Txawm hais tias titanium pom zoo corrosion kuj rau ntau cov kua qaub, nws tseem tuaj yeem cuam tshuam nrog lawv nyob rau hauv qee yam mob. Tshwj xeeb ntawm qhov kub thiab txias, hydrochloric acid (HCl) thiab sulfuric acid (H₂SO₄) ua rau kom cov txheej txheem corrosion ntawm titanium. Txawm hais tias cov tshuaj tiv thaiv no kuj qeeb, txhawm rau txhim kho corrosion kuj ntawm titanium anodes, cov ntaub ntawv tiv thaiv xws li platinum lossis iridium feem ntau yog siv los tiv thaiv kev xeb. Hauv cov ntawv thov tseem ceeb xws li electroplating thiab kev kho dej, qhov tsis zoo ntawm titanium-cov tshuaj tiv thaiv acid yuav tsum tau saib xyuas tshwj xeeb. Txhawm rau txhim kho corrosion tsis kam ntawm titanium, sib xyaw hlau oxide (MMO) txheej tshuab feem ntau yog siv los tiv thaiv.
Titanium Reaction nrog Alkaline Solutions: Titanium nthuav tawm zoo heev corrosion kuj rau feem ntau alkaline daws. Qhov no yog vim li cas titanium anodes ua tau zoo tshwj xeeb hauv qhov chaw muaj zog alkaline, xws li cov txheej txheem electrochemical uas muaj sodium hydroxide (NaOH) hauv kev kho dej. Nyob rau hauv cov xwm txheej no, oxide zaj duab xis ntawm titanium nto tseem ruaj khov, tiv thaiv cov tshuaj tiv thaiv tseem ceeb.
Titanium reacts nrog carbon (C) ntawm qhov kub thiab txias los tsim titanium carbide (TiC). Titanium carbide paub txog nws cov hardness tsis tshua muaj siab thiab feem ntau siv rau hauv kev tsim cov cuab yeej txiav. Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias hauv cov ntawv thov kev lag luam, qhov kub thiab txias tsim los ntawm kev siv titanium anodes feem ntau qis dua qhov ntsuas kub uas yuav tsum tau ua rau kev tsim cov titanium carbide.
Vim li cas thiaj xaiv Titanium-Based Anodes?
Titanium yog heev nyiam nyob rau hauv kev lag luam daim ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv electrochemical daim ntaub ntawv, vim nws tshwj xeeb reactivity. Qhov kev ua tau zoo ntawm titanium anodes yog los ntawm ntau qhov txiaj ntsig tseem ceeb: Kev Tiv Thaiv Zoo Tshaj Plaws: Titanium tsim cov oxide zaj duab xis ruaj khov nyob rau hauv ob qho tib si acidic thiab alkaline ib puag ncig, muab kev tiv thaiv muaj zog thiab ua kom ntev - lub sijhawm ua haujlwm ruaj khov, txo cov nqi tu thiab sijhawm poob. Flexible Customization: Titanium anodes tuaj yeem kho nrog ntau yam ntaub ntawv kom tau raws li kev xav tau ntawm kev lag luam sib txawv. Piv txwv li, platinum-coated titanium anodes ua tau zoo heev hauv cov tshuaj chlorine- nplua nuj ib puag ncig, thaum MMO-coated titanium anodes qhia tau zoo dua nyob rau hauv lwm yam kev siv electrochemical. Lub cev muaj zog: Titanium tuav lub zog siab ntawm qhov kub thiab txias, ua rau nws zoo tagnrho rau kev lag luam uas xav tau kev ua haujlwm siab, xws li hydrogen electrolysis thiab dej kho. Environmental Advantages: Kev ua haujlwm siab ntawm titanium anodes tsis tsuas yog txuag lub zog tab sis kuj txo cov nqi khiav lag luam. Nyob rau tib lub sijhawm, lawv pab txhawb rau cov txheej txheem ib puag ncig zoo dua thiab txo qis kev cia siab rau cov tshuaj lom neeg.
