1. Isingeniso
Njengengcezu yesisetshenziswa esibalulekile embonini yamakhemikhali, ama-electrolyzer athambekele ekugqwaleni ngenxa yokuchayeka isikhathi eside emithonjeni yamakhemikhali, okuthinta kabi ukusebenza kwawo, impilo yesevisi, futhi okusongela ukuphepha kokukhiqiza ikakhulukazi. Ngakho-ke, ukusebenzisa izindlela eziphumelelayo zokulwa nokugqwala kubalulekile. Okwamanje, amanye amabhizinisi asebenzisa izinto ezifana nezinhlanganisela zerabha-zepulasitiki noma irabha ye-butyl ecijile ukuze zivikeleke, kodwa imiphumela ngokuvamile ayigculisi. Nakuba kuphumelela ekuqaleni, ukusebenza kwe-anti-corrosion kwehla kakhulu ngemva kweminyaka engu-1-2, okuholela ekulimaleni okukhulu. Uma kucatshangelwa zombili izici zobuchwepheshe nezomnotho, ibha ye-Glass Fiber Reinforced Polymer (GFRP) iyinketho efanelekile yezinto ezimelana nokugqwala kuma-electrolyzer. Ngaphandle kokuba nezinto ezinhle kakhulu zemishini,Ibha ye-GFRPfuthi ikhombisa ukumelana nokugqwala kwamakhemikhali okuvelele, ithola ukunakwa okusabalele okuvela emabhizinisini emboni ye-chlor-alkali. Njengenye yezinto ezisetshenziswa kakhulu ukumelana nokugqwala, ifaneleka kakhulu okokusebenza okuvezwe emithonjeni yezindaba efana ne-chlorine, i-alkali, i-hydrochloric acid, i-brine, namanzi. Lesi sihloko sethula ngokuyinhloko ukusetshenziswa kwe-GFRP rebar, kusetshenziswa i-glass fibre njengesiqinisi kanye ne-epoxy resin njenge-matrix, kuma-electrolyzer.

2. Ukuhlaziywa Kwezinto Zokulimala Kokugqwala Kuma-Electrolyzers
Ngaphandle kokuthonywa yi-electrolyzer's material, ukwakheka, namasu okwakha, ukugqwala ngokuyinhloko kubangelwa imidiya yangaphandle egqwalayo. Lokhu kuhlanganisa igesi ye-chlorine emanzi enezinga lokushisa eliphezulu, isixazululo se-sodium chloride enezinga lokushisa eliphezulu, utshwala obune-alkali obune-chlorine, kanye nomhwamuko wamanzi we-chlorine ogcwele izinga lokushisa eliphezulu. Ngaphezu kwalokho, imisinga elahlekile ekhiqizwa ngesikhathi senqubo ye-electrolysis ingasheshisa ukugqwala. Igesi ye-chlorine emanzi enezinga eliphezulu lokushisa eliphezulu ekhiqizwa ekamelweni le-anode ithwala inani elikhulu lomhwamuko wamanzi. I-Hydrolysis yegesi ye-chlorine ikhiqiza i-hydrochloric acid edla kakhulu futhi i-oxidizing i-hypochlorous acid enamandla. Ukubola kwe-hypochlorous acid kukhipha umoya-mpilo osafufusa. Lezi zindaba zisebenza kakhulu ngamakhemikhali, futhi ngaphandle kwe-titanium, izinto eziningi eziyinsimbi nezingezona ezensimbi zigqwala kakhulu kule ndawo. Isitshalo sethu ekuqaleni sasisebenzisa amagobolondo ensimbi afakwe irabha eqinile yemvelo ukuze kuvikelwe ukugqwala. Ibanga layo lokumelana nezinga lokushisa lalingu-0–80°C kuphela, elingaphansi kwezinga lokushisa elizungezile lendawo edlayo. Ngaphezu kwalokho, irabha eqinile yemvelo ayimelani ne-hypochlorous acid corrosion. Ulwelwesi belusengozini yokulimala ezindaweni eziwuketshezi oluwuketshezi, okuholela ekubhobokeni okugqwalile kwegobolondo lensimbi.

3. Ukusetshenziswa kwe-GFRP Rebar kuma-Electrolyzers
3.1 Izimpawu zeI-GFRP Rebar
I-rebar ye-GFRP iyinhlanganisela entsha yezinto ekhiqizwa i-pultrusion, isebenzisa i-glass fiber njenge-reinforcement kanye ne-epoxy resin njenge-matrix, elandelwa ukuphulukiswa kwezinga lokushisa eliphezulu nokwelashwa okukhethekile kwendawo. Le nto ihlinzeka ngezakhiwo ezinhle kakhulu zemishini kanye nokumelana nokugqwala kwamakhemikhali okuvelele, ikakhulukazi okudlula imikhiqizo eminingi yefiber ukumelana nezixazululo ze-asidi ne-alkali. Ukwengeza, ayi-conductive, ayihambisani ne-thermally, ine-coefficient ephansi yokwanda okushisayo, futhi inokunwebeka okuhle nokuqina. Inhlanganisela ye-glass fibre kanye ne-resin ithuthukisa futhi ukumelana kwayo nokugqwala. Yilezi zakhiwo zamakhemikhali ezivelele eziyenza ibe yinto ekhethwayo yokuvikela ukugqwala kuma-electrolyzer.

Ngaphakathi kwe-electrolyzer, ama-rebar e-GFRP ahlelwa ngokuhambisana ngaphakathi kwezindonga zethangi, futhi ukhonkolo we-vinyl ester resin uthululelwa phakathi kwawo. Ngemva kokuqiniswa, lokhu kwakha isakhiwo esibalulekile. Lo mklamo uthuthukisa kakhulu ukuqina komzimba wethangi, ukumelana nokugqwala kwe-asidi nokugqwala kwe-alkali, kanye nezakhiwo zokuvikela. Iphinde yandise isikhala sangaphakathi sethangi, inciphise imvamisa yokulungisa, futhi inwebe impilo yesevisi. Ilungele ikakhulukazi izinqubo ze-electrolysis ezidinga amandla aphezulu nokusebenza okuqinile.

3.3 Izinzuzo Zokusebenzisa Ibha ye-GFRP kuma-Electrolyzers
Ukuvikela ukugqwala kwe-electrolyzer kwendabuko kuvame ukusebenzisa izindlela zokukhonkolo ezisakazwa nge-resin. Kodwa-ke, amathangi kakhonkolo asindayo, anezikhathi ezinde zokuphulukisa, aholela ekusebenzeni kahle kokwakhiwa kwendawo, futhi athambekele ekubeni namabhamuza nezindawo ezingalingani. Lokhu kungaholela ekuvuzeni kwe-electrolyte, ukugqwala komzimba wethangi, ukuphazamisa ukukhiqizwa, ukungcolisa imvelo, kanye nokufaka izindleko eziphezulu zokunakekela. Ukusebenzisa i-rebar ye-GFRP njengento evimbela ukugqwala kunqoba ngempumelelo lezi zihibe: umzimba wethangi awusindi, unamandla okuthwala umthwalo omkhulu, ukumelana nokugqwala okuhle kakhulu, kanye nezakhiwo ezigobayo neziqinile. Ngesikhathi esifanayo, inikeza izinzuzo ezifana nomthamo omkhulu, impilo yesevisi ende, ukulungiswa okuncane, kanye nokulula kokuphakamisa nokuhamba.

4. Isifinyezo
I-epoxy-basedIbha ye-GFRPihlanganisa izici ezinhle kakhulu zomshini, zomzimba, kanye namakhemikhali azo zombili izingxenye. Isetshenziswe kabanzi ukuxazulula izinkinga zokugqwala embonini ye-chlor-alkali kanye nezakhiwo zikakhonkolo ezifana namahubhu, ama-pavements, namadekhi amabhuloho. Ukuzijwayeza kubonise ukuthi ukusebenzisa le nto kungathuthukisa kakhulu ukumelana nokugqwala nempilo yesevisi yama-electrolyzer, ngaleyo ndlela kuthuthukise ukuphepha kokukhiqiza. Kuncike ekutheni idizayini yesakhiwo inengqondo, ukukhethwa kwempahla nezilinganiso kufanelekile, futhi inqubo yokwakha imisiwe, i-rebar ye-GFRP ingathuthukisa kakhulu ukusebenza kokunqanda ukugqwala kwama-electrolyzer. Ngakho-ke, lobu buchwepheshe buphethe amathemba okusebenza abanzi futhi bufanele ukukhuthazwa okusabalele.
