1. Taw qhia
Raws li ib qho tseem ceeb ntawm cov cuab yeej siv hauv kev lag luam tshuaj, cov khoom siv hluav taws xob muaj feem cuam tshuam rau kev xeb vim kev cuam tshuam rau cov tshuaj lom neeg mus sij hawm ntev, cuam tshuam rau lawv cov kev ua tau zoo, kev pab lub neej, thiab tshwj xeeb tshaj yog tsim kev nyab xeeb. Yog li ntawd, kev siv cov tshuaj tiv thaiv corrosion yog qhov tseem ceeb. Tam sim no, qee lub tuam txhab siv cov ntaub ntawv xws li roj hmab-yas sib xyaw lossis vulcanized butyl roj hmab rau kev tiv thaiv, tab sis cov txiaj ntsig feem ntau tsis txaus siab. Thaum pib ua haujlwm zoo, kev ua haujlwm tiv thaiv corrosion ua rau poob qis tom qab 1-2 xyoos, ua rau muaj kev puas tsuaj loj. Xav txog ob qho tib si kev lag luam thiab kev lag luam, iav Fiber Reinforced Polymer (GFRP) rebar yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv tiv thaiv corrosion hauv electrolyzers. Dhau li muaj cov khoom siv kho tshuab zoo heev,GFRP rovkuj qhia tau zoo heev tshuaj corrosion kuj, garnering dav saib los ntawm chlor-alkali kev lag luam qhauj. Raws li ib qho ntawm cov khoom siv corrosion-resistant ntau tshaj plaws, nws yog tshwj xeeb tshaj yog haum rau cov khoom siv los ntawm kev tshaj tawm xws li chlorine, alkalis, hydrochloric acid, brine, thiab dej. Cov kab lus no feem ntau qhia txog daim ntawv thov ntawm GFRP rebar, siv cov iav fiber ntau raws li qhov kev txhawb zog thiab epoxy resin li matrix, hauv electrolyzers.

2. Kev soj ntsuam ntawm Corrosion Damage Factors hauv Electrolyzers
Sib nrug los ntawm kev cuam tshuam los ntawm electrolyzer tus kheej cov khoom, qauv, thiab kev tsim kho, corrosion feem ntau stems los ntawm lwm yam corrosive media. Cov no suav nrog cov roj chlorine uas kub kub, kub-kub sodium chloride tov, chlorine-muaj alkali cawv, thiab kub-saturated chlorine dej vapor. Tsis tas li ntawd, cov stray tam sim no generated thaum lub sij hawm electrolysis txheej txheem yuav ua rau kom corrosion. Qhov kub-kub ntub dej chlorine gas tsim nyob rau hauv lub anode chamber nqa ib tug loj npaum li cas ntawm cov dej vapor. Hydrolysis ntawm cov roj chlorine ua rau corrosive hydrochloric acid heev thiab muaj zog oxidizing hypochlorous acid. Lub decomposition ntawm hypochlorous acid tso tawm nascent oxygen. Cov xov xwm no yog cov tshuaj lom neeg muaj zog heev, thiab tshwj tsis yog titanium, feem ntau cov khoom siv hlau thiab cov hlau tsis yog hlau raug kev puas tsuaj loj hauv ib puag ncig. Peb cov nroj tsuag Ameslikas siv steel shells lined nrog ntuj tawv roj hmab rau kev tiv thaiv corrosion. Nws qhov ntsuas kub tsis kam tsuas yog 0-80 ° C, uas yog qis dua qhov ntsuas kub ntawm qhov chaw corrosive. Ntxiv mus, ntuj tawv roj hmab tsis resistant rau hypochlorous acid corrosion. Cov hauv ob sab phlu tau raug puas tsuaj nyob rau hauv vapor-kua ib puag ncig, ua rau corrosive perforation ntawm lub plhaub hlau.

3. Daim ntawv thov ntawm GFRP Rebar hauv Electrolyzers
3.1 Cov yam ntxwv ntawmGFRP Cov
GFRP rebar yog cov khoom sib xyaw tshiab uas tsim los ntawm pultrusion, siv cov iav fiber ntau raws li qhov kev txhawb zog thiab epoxy resin raws li matrix, ua raws li kev kub kub thiab kev kho mob tshwj xeeb. Cov khoom siv no muaj cov khoom siv zoo heev thiab cov tshuaj tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog cov khoom siv fiber ntau hauv cov tshuaj tiv thaiv acid thiab alkali. Tsis tas li ntawd, nws yog non-conductive, non-thermally conductive, tsis tshua muaj coefficient ntawm thermal expansion, thiab muaj zoo elasticity thiab toughness. Kev sib xyaw ua ke ntawm cov iav fiber ntau thiab cov resin ntxiv txhim kho nws cov corrosion kuj. Nws yog qhov tseeb ntawm cov khoom siv tshuaj lom neeg uas ua rau nws nyiam cov khoom siv rau kev tiv thaiv corrosion hauv electrolyzers.

Nyob rau hauv lub electrolyzer, GFRP rebars yog teem rau tib lub sij hawm nyob rau hauv lub tank phab ntsa, thiab vinyl ester resin pob zeb yog poured ntawm lawv. Tom qab solidification, qhov no tsim ib qho qauv. Qhov kev tsim no tseem ceeb txhim kho lub cev lub cev muaj zog, tiv taus cov kua qaub thiab alkali corrosion, thiab rwb thaiv tsev. Nws kuj ua rau kom qhov chaw sab hauv ntawm lub tank, txo kev tu ntau zaus, thiab ncua kev pab cuam lub neej. Nws yog tshwj xeeb tshaj yog haum rau cov txheej txheem electrolysis uas yuav tsum tau muaj zog thiab tensile kev ua tau zoo.

3.3 Qhov zoo ntawm Kev Siv GFRP Rebar hauv Electrolyzers
Ib txwm siv electrolyzer corrosion tiv thaiv feem ntau siv cov txheej txheem cob-cam khwb cia. Txawm li cas los xij, cov twj tso kua mis pob zeb hnyav hnyav, muaj lub sijhawm kho ntev, ua rau muaj kev tsim kho ntawm qhov chaw qis, thiab ua rau muaj npuas thiab tsis sib xws. Qhov no tuaj yeem ua rau electrolyte to, corroding lub tank lub cev, cuam tshuam kev tsim khoom, ua paug rau ib puag ncig, thiab ua rau cov nqi kho mob siab. Siv GFRP rebar ua cov khoom siv los tiv thaiv corrosion zoo kov yeej cov teeb meem no: lub tank lub cev yog lub teeb yuag, muaj peev xwm thauj khoom siab, zoo heev corrosion resistance, thiab superior dabtsi yog khoov thiab tensile zog. Ib txhij, nws muaj qhov zoo xws li lub peev xwm loj, lub neej ua haujlwm ntev, kev saib xyuas tsawg, thiab yooj yim ntawm hoisting thiab kev thauj mus los.

4. Cov ntsiab lus
Epoxy-basedGFRP rovcombines cov khoom siv zoo heev, lub cev, thiab tshuaj lom neeg ntawm ob qho tib si. Nws tau siv dav siv los daws cov teeb meem corrosion hauv kev lag luam chlor-alkali thiab hauv cov vaj tse pob zeb xws li tunnels, pavements, thiab choj decks. Kev xyaum tau pom tias kev siv cov khoom siv no tuaj yeem txhim kho qhov kev tiv thaiv corrosion thiab kev pab cuam lub neej ntawm electrolyzers, yog li txhim kho kev ruaj ntseg ntau lawm. Muab cov qauv tsim tsim nyog, kev xaiv cov khoom siv thiab kev faib ua feem yog qhov tsim nyog, thiab cov txheej txheem tsim kho yog tus qauv, GFRP rebar tuaj yeem txhim kho kev tiv thaiv corrosion ntawm electrolyzers. Yog li ntawd, qhov kev siv tshuab no tuav cov ntawv thov dav dav thiab tsim nyog rau kev nthuav dav dav.
