1. Kev Taw Qhia
Ua ib qho khoom siv tseem ceeb hauv kev lag luam tshuaj lom neeg, cov electrolyzers feem ntau raug xeb vim yog kev raug tshuaj lom neeg ntev ntev, cuam tshuam tsis zoo rau lawv cov kev ua tau zoo, lub neej ua haujlwm, thiab tshwj xeeb tshaj yog hem kev nyab xeeb ntawm kev tsim khoom. Yog li ntawd, kev siv cov kev ntsuas tiv thaiv xeb zoo yog qhov tseem ceeb. Tam sim no, qee lub tuam txhab siv cov ntaub ntawv xws li cov roj hmab-yas sib xyaw lossis cov roj hmab butyl vulcanized rau kev tiv thaiv, tab sis cov txiaj ntsig feem ntau tsis txaus siab. Txawm hais tias ua haujlwm tau zoo thaum pib, kev ua haujlwm tiv thaiv xeb poob qis tom qab 1-2 xyoos, ua rau muaj kev puas tsuaj loj heev. Xav txog ob qho tib si kev siv tshuab thiab kev lag luam, Iav Fiber Reinforced Polymer (GFRP) rebar yog qhov kev xaiv zoo tshaj plaws rau cov ntaub ntawv tiv thaiv xeb hauv electrolyzers. Dhau li ntawm kev muaj cov khoom siv kho tshuab zoo heev,GFRP rebarkuj qhia tau tias muaj kev tiv thaiv xeb zoo heev, tau txais kev saib xyuas dav dav los ntawm cov tuam txhab lag luam chlor-alkali. Raws li ib qho ntawm cov ntaub ntawv tiv thaiv xeb siv dav tshaj plaws, nws yog qhov tshwj xeeb tshaj yog rau cov khoom siv uas raug rau cov xov xwm xws li chlorine, alkalis, hydrochloric acid, brine, thiab dej. Tsab xov xwm no feem ntau qhia txog kev siv GFRP rebar, siv iav fiber ua lub zog txhawb nqa thiab epoxy resin ua lub matrix, hauv electrolyzers.

2. Kev Tshawb Fawb Txog Cov Yam Uas Ua Rau Muaj Kev Puas Tsuaj Los Ntawm Kev Xeb Hauv Cov Tshuab Hluav Taws Xob
Sib nrug los ntawm kev cuam tshuam los ntawm cov khoom siv, cov qauv, thiab cov txheej txheem tsim kho ntawm lub electrolyzer, kev xeb feem ntau yog los ntawm cov xov xwm corrosive sab nraud. Cov no suav nrog cov pa roj chlorine ntub dej kub siab, cov kua sodium chloride kub siab, cov kua alkali uas muaj chlorine, thiab cov pa dej chlorine uas kub siab. Ntxiv mus, cov dej ntws uas tsim thaum lub sijhawm electrolysis tuaj yeem ua rau kev xeb sai dua. Cov pa roj chlorine ntub dej kub siab uas tsim tawm hauv lub chamber anode nqa cov pa dej ntau heev. Hydrolysis ntawm cov pa roj chlorine tsim cov kua qaub hydrochloric acid uas muaj zog heev thiab cov kua qaub hypochlorous uas muaj zog oxidizing. Kev lwj ntawm cov kua qaub hypochlorous tso tawm cov pa oxygen tshiab. Cov xov xwm no muaj zog heev, thiab tshwj tsis yog titanium, feem ntau cov khoom siv hlau thiab cov khoom siv tsis yog hlau raug kev xeb hnyav hauv qhov chaw no. Peb lub Hoobkas thawj zaug siv cov plhaub hlau uas muaj roj hmab tawv ntuj rau kev tiv thaiv kev xeb. Nws qhov kub thiab txias tsis kam tsuas yog 0–80 ° C, uas qis dua qhov kub thiab txias ntawm qhov chaw corrosive. Ntxiv mus, cov roj hmab tawv ntuj tsis tiv taus kev xeb hypochlorous acid. Lub txheej sab hauv yog qhov yooj yim rau kev puas tsuaj hauv cov pa dej-kua, ua rau muaj kev puas tsuaj ntawm lub plhaub hlau.

3. Daim ntawv thov ntawm GFRP Rebar hauv Electrolyzers
3.1 Cov yam ntxwv ntawmGFRP Rebar
GFRP rebar yog cov khoom siv sib xyaw tshiab tsim los ntawm pultrusion, siv cov iav fiber ua lub zog txhawb nqa thiab epoxy resin ua lub matrix, ua raws li kev kho kub siab thiab kev kho qhov chaw tshwj xeeb. Cov khoom siv no muaj cov khoom siv kho tshuab zoo heev thiab kev tiv thaiv xeb tshuaj zoo heev, tshwj xeeb tshaj yog ua tau zoo dua li feem ntau cov khoom fiber hauv kev tiv thaiv cov kua qaub thiab alkali. Tsis tas li ntawd, nws tsis yog conductive, tsis thermally conductive, muaj cov coefficient qis ntawm thermal nthuav dav, thiab muaj elasticity zoo thiab toughness. Kev sib xyaw ua ke ntawm iav fiber thiab resin ntxiv txhim kho nws txoj kev tiv thaiv xeb. Nws yog cov khoom siv tshuaj lom neeg tseem ceeb no uas ua rau nws yog cov khoom siv nyiam rau kev tiv thaiv xeb hauv electrolyzers.

Hauv lub tshuab electrolyzer, GFRP rebars tau teeb tsa sib luag hauv cov phab ntsa tank, thiab cov vinyl ester resin concrete tau nchuav rau ntawm lawv. Tom qab khov, qhov no tsim ib qho qauv sib xyaw. Qhov kev tsim no ua rau lub cev tank muaj zog dua, tiv taus acid thiab alkali corrosion, thiab cov khoom rwb thaiv tsev. Nws kuj ua rau lub tank muaj qhov chaw sab hauv ntau dua, txo qhov zaus txij nkawm, thiab ntev lub neej kev pabcuam. Nws yog qhov tsim nyog rau cov txheej txheem electrolysis uas xav tau lub zog siab thiab kev ua haujlwm tensile.

3.3 Cov txiaj ntsig ntawm kev siv GFRP Rebar hauv electrolyzers
Kev tiv thaiv xeb los ntawm electrolyzer feem ntau siv cov txheej txheem ua los ntawm cov pob zeb ua los ntawm cov resin. Txawm li cas los xij, cov thoob dej ua los ntawm cov pob zeb ua los ntawm cov pob zeb no hnyav, muaj lub sijhawm kho ntev, ua rau kev tsim kho tsis zoo, thiab yooj yim muaj npuas thiab cov nplaim tsis sib luag. Qhov no tuaj yeem ua rau cov electrolyte xau, ua rau lub cev lub tank xeb, cuam tshuam kev tsim khoom, ua rau ib puag ncig tsis huv, thiab raug nqi kho ntau. Kev siv GFRP rebar ua cov khoom siv tiv thaiv xeb ua tau zoo kov yeej cov teeb meem no: lub cev lub tank tsis hnyav, muaj peev xwm thauj khoom tau zoo, tiv taus xeb zoo heev, thiab cov khoom khoov thiab tensile zoo heev. Tib lub sijhawm, nws muaj cov txiaj ntsig xws li muaj peev xwm loj, lub neej ua haujlwm ntev, kev saib xyuas tsawg kawg nkaus, thiab yooj yim ntawm kev nqa thiab kev thauj mus los.

4. Cov Lus Qhia Luv Luv
Ua los ntawm epoxyGFRP rebarua ke cov khoom siv kho tshuab, lub cev, thiab tshuaj lom neeg zoo heev ntawm ob qho khoom. Nws tau siv dav dav los daws cov teeb meem xeb hauv kev lag luam chlor-alkali thiab hauv cov qauv pob zeb xws li qhov av, txoj kev taug kev, thiab cov choj. Kev xyaum tau qhia tias kev siv cov khoom no tuaj yeem txhim kho qhov kev tiv thaiv xeb thiab lub neej ua haujlwm ntawm cov electrolyzers, yog li txhim kho kev nyab xeeb ntawm kev tsim khoom. Yog tias qhov kev tsim qauv tsim nyog, kev xaiv cov khoom siv thiab cov feem pua ​​​​​​yog tsim nyog, thiab cov txheej txheem tsim kho tau raug qauv, GFRP rebar tuaj yeem txhim kho qhov kev ua tau zoo tiv thaiv xeb ntawm cov electrolyzers. Yog li ntawd, cov thev naus laus zis no tuav cov kev cia siab dav dav thiab tsim nyog rau kev txhawb nqa dav dav.
