1. Mawu Oyamba
Monga chida chofunikira kwambiri pamakampani opanga mankhwala, ma electrolyzer amatha kuwonongeka chifukwa chokhala ndi nthawi yayitali pama media azamankhwala, zomwe zimasokoneza magwiridwe antchito awo, moyo wautumiki, komanso kuwopseza chitetezo chopanga. Chifukwa chake, kugwiritsa ntchito njira zothana ndi dzimbiri ndikofunikira. Pakadali pano, mabizinesi ena amagwiritsa ntchito zida zopangira mphira-pulasitiki kapena mphira wa butyl kuti atetezedwe, koma zotsatira zake nthawi zambiri sizikhala zogwira mtima. Ngakhale zogwira ntchito poyambilira, zotsutsana ndi dzimbiri zimawonongeka pambuyo pa zaka 1-2, zomwe zimapangitsa kuwonongeka kwakukulu. Poganizira zaukadaulo komanso zachuma, Glass Fiber Reinforced Polymer (GFRP) rebar ndi yabwino kusankha zida zolimbana ndi dzimbiri mu ma electrolyzer. Kuphatikiza pa kukhala ndi zida zabwino zamakina,Chithunzi cha GFRPikuwonetsanso kukana kwa dzimbiri kwamankhwala, kukopa chidwi chofala kuchokera kumabizinesi amakampani a chlor-alkali. Monga chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri polimbana ndi dzimbiri, ndizoyenera kwambiri zida zomwe zimawonetsedwa ndi media monga chlorine, alkalis, hydrochloric acid, brine, ndi madzi. Nkhaniyi ikufotokoza za kagwiritsidwe ntchito ka GFRP rebar, pogwiritsa ntchito utomoni wagalasi monga kulimbikitsa ndi utomoni wa epoxy ngati matrix, mu electrolyzers.

2. Kusanthula kwa Zowonongeka Zowonongeka mu Electrolyzers
Kupatula kukhudzidwa ndi zinthu zomwe electrolyzer yake, kapangidwe kake, ndi njira zake zomangira, dzimbiri makamaka zimachokera kuzinthu zowononga zakunja. Izi zikuphatikizapo mpweya wonyowa wa klorini wotentha kwambiri, madzi otsekemera a sodium chloride, mowa wa alkali wokhala ndi chlorine, ndi nthunzi wamadzi wa chlorine wodzaza ndi kutentha kwambiri. Kuphatikiza apo, mafunde osokera omwe amapangidwa panthawi ya electrolysis amatha kufulumizitsa dzimbiri. Mpweya wonyowa kwambiri wa klorini wopangidwa m'chipinda cha anode umanyamula nthunzi wambiri wamadzi. Hydrolysis ya mpweya wa chlorine imapanga hydrochloric acid yowononga kwambiri komanso oxidizing hypochlorous acid. Kuwola kwa asidi wa hypochlorous kumatulutsa mpweya wotuluka. Makanemawa amagwira ntchito kwambiri, kupatulapo titaniyamu, zida zambiri zachitsulo komanso zopanda zitsulo zimachita dzimbiri kwambiri pamalo ano. Chomera chathu poyamba chinkagwiritsa ntchito zipolopolo zachitsulo zokhala ndi mphira wolimba wachilengedwe pofuna kuteteza dzimbiri. Kutentha kwake kukana kutentha kunali 0-80 ° C kokha, komwe kumakhala kotsika kusiyana ndi kutentha kozungulira kwa malo owononga. Komanso, mphira wolimba wachilengedwe sulimbana ndi dzimbiri la hypochlorous acid. Chingwecho chinkawonongeka mosavuta m'malo okhala ndi nthunzi, zomwe zimapangitsa kuti chipolopolo chachitsulo chiwonongeke.

3. Kugwiritsa ntchito GFRP Rebar mu Electrolyzers
3.1 Makhalidwe aGFRP Rebar
GFRP rebar ndi chinthu chatsopano chopangidwa ndi pultrusion, chogwiritsira ntchito galasi fiber monga kulimbikitsa ndi epoxy resin monga matrix, kutsatiridwa ndi kuchiritsa kwa kutentha kwambiri ndi chithandizo chapadera chapamwamba. Izi zimapereka mawonekedwe abwino amakina komanso kukana kwa dzimbiri kwamankhwala, makamaka kuposa zinthu zambiri zama fiber polimbana ndi asidi ndi alkali. Kuonjezera apo, si conductive, non-thermally conductive, ali ndi coefficient yochepa ya kukula kwa matenthedwe, ndipo imakhala ndi kusungunuka bwino ndi kulimba. Kuphatikiza kwa utomoni wagalasi ndi utomoni kumawonjezera kukana kwa dzimbiri. Ndizinthu zodziwika bwino zamankhwala izi zomwe zimapangitsa kukhala chinthu chomwe chimakondedwa kwambiri poteteza dzimbiri mu ma electrolyzer.

Mkati mwa electrolyzer, ma GFRP rebars amakonzedwa mofanana mkati mwa makoma a thanki, ndipo vinyl ester resin konkire imatsanuliridwa pakati pawo. Pambuyo kulimbitsa, izi zimapanga dongosolo lofunikira. Kapangidwe kameneka kamapangitsa kuti tanki ikhale yolimba, kukana dzimbiri la asidi ndi alkali, komanso kutsekereza katundu. Imawonjezeranso malo amkati mwa thanki, imachepetsa kukonzanso pafupipafupi, ndikuwonjezera moyo wautumiki. Ndikoyenera makamaka pamayendedwe a electrolysis omwe amafunikira mphamvu zambiri komanso magwiridwe antchito.

3.3 Ubwino Wogwiritsa Ntchito GFRP Rebar mu Electrolyzers
Chitetezo chachikhalidwe cha electrolyzer corrosion nthawi zambiri chimagwiritsa ntchito njira zopangira konkriti. Komabe, matanki a konkriti ndi olemetsa, amakhala ndi nthawi yayitali yochiritsa, zomwe zimapangitsa kuti pakhale ntchito yomanga pamalopo, ndipo amakonda kuthyoka komanso malo osafanana. Izi zitha kupangitsa kuti ma electrolyte atayike, kuwononga tanki, kusokoneza kupanga, kuwononga chilengedwe, komanso kuwononga ndalama zambiri kukonza. Kugwiritsa ntchito rebar ya GFRP ngati anti-corrosion kumathetsa zovuta izi: thankiyo ndi yopepuka, imatha kunyamula katundu wambiri, kukana kwa dzimbiri, komanso kupindika kwapamwamba komanso kulimba. Nthawi yomweyo, imapereka zabwino monga kuchuluka kwakukulu, moyo wautali wautumiki, kukonza pang'ono, komanso kumasuka kokweza ndi mayendedwe.

4. Mwachidule
Epoxy-basedChithunzi cha GFRPamaphatikiza mawotchi, thupi, ndi mankhwala azinthu zonse ziwirizi. Amagwiritsidwa ntchito kwambiri pothana ndi zovuta za dzimbiri m'makampani a chlor-alkali komanso m'mapangidwe a konkire monga ma tunnel, mapaipi, ndi ma milatho. Zochita zasonyeza kuti kugwiritsa ntchito nkhaniyi kungathandize kwambiri kukana dzimbiri ndi moyo utumiki wa electrolyzers, potero kukonza chitetezo kupanga. Malinga ndi kapangidwe kake ndi koyenera, kusankha kwazinthu ndi kuchuluka kwake kuli koyenera, ndipo njira yomangayo ndiyokhazikika, GFRP rebar imatha kupititsa patsogolo ntchito zotsutsana ndi dzimbiri zama electrolyzer. Chifukwa chake, ukadaulo uwu uli ndi mwayi wogwiritsa ntchito kwambiri ndipo ndiyoyenera kukwezedwa kwambiri.
