1. Isingeniso
Njengengxenye ebalulekile yemishini embonini yamakhemikhali, ama-electrolyzer athambekele ekugqwaleni ngenxa yokuchayeka isikhathi eside kumakhemikhali, okuthinta kabi ukusebenza kwawo, impilo yesevisi, futhi ikakhulukazi ukusongela ukuphepha kokukhiqiza. Ngakho-ke, ukusebenzisa izindlela zokulwa nokugqwala ezisebenzayo kubalulekile. Njengamanje, amanye amabhizinisi asebenzisa izinto ezifana nezinhlanganisela zerabha-plastiki noma irabha ye-butyl evulcanized ukuze avikeleke, kodwa imiphumela ivame ukungagculisi. Nakuba isebenza kahle ekuqaleni, ukusebenza kokulwa nokugqwala konakala kakhulu ngemva kweminyaka eyi-1-2, okuholela emonakalweni omkhulu. Uma sibheka izici zobuchwepheshe nezomnotho, i-Glass Fiber Reinforced Polymer (GFRP) rebar iyindlela efanelekile yezinto ezingamelana nokugqwala kuma-electrolyzer. Ngaphandle kokuba nezakhiwo ezinhle kakhulu zemishini,Ibha ye-GFRPfuthi ikhombisa ukumelana nokugqwala kwamakhemikhali okuvelele, okuthola ukunakwa okubanzi emabhizinisini ezimboni ze-chlor-alkali. Njengenye yezinto ezisetshenziswa kakhulu ezingagqwali, ifaneleka kakhulu imishini evezwe ezintweni ezifana ne-chlorine, i-alkalis, i-hydrochloric acid, i-brine, namanzi. Lesi sihloko sethula ngokuyinhloko ukusetshenziswa kwe-GFRP rebar, kusetshenziswa i-glass fiber njenge-reinforcement kanye ne-epoxy resin njenge-matrix, kuma-electrolyzer.

2. Ukuhlaziywa Kwezinto Ezibangela Umonakalo Wokugqwala Kuma-Electrolyzer
Ngaphandle kokuthonywa yizinto zokwakha, isakhiwo, kanye namasu okwakha e-electrolyzer, ukugqwala kubangelwa kakhulu yizinto zangaphandle ezigqwalisayo. Lokhu kufaka phakathi igesi ye-chlorine emanzi eshisa kakhulu, isisombululo se-sodium chloride eshisa kakhulu, utshwala be-alkali obuqukethe i-chlorine, kanye nomhwamuko wamanzi we-chlorine ogcwele eshisa kakhulu. Ngaphezu kwalokho, imisinga elahlekile ekhiqizwa ngesikhathi senqubo ye-electrolysis ingasheshisa ukugqwala. Igesi ye-chlorine emanzi eshisa kakhulu ekhiqizwa ekamelweni le-anode ithwala inani elikhulu lomhwamuko wamanzi. I-hydrolysis yegesi ye-chlorine ikhiqiza i-hydrochloric acid egqwalisayo kakhulu kanye ne-hypochlorous acid enamandla kakhulu. Ukubola kwe-hypochlorous acid kukhipha i-oxygen esafufusa. Lezi zinto zisebenza kakhulu ngamakhemikhali, futhi ngaphandle kwe-titanium, izinto eziningi zensimbi nezingezona ezensimbi zihlushwa ukugqwala okukhulu kule ndawo. Isitshalo sethu ekuqaleni sasisebenzisa amagobolondo ensimbi afakwe irabha eqinile yemvelo ukuvikela ukugqwala. Ibanga layo lokumelana nokushisa laliyi-0–80°C kuphela, okuphansi kunokushisa okuzungezile kwendawo egqwalisayo. Ngaphezu kwalokho, irabha eqinile yemvelo ayimelani nokugqwala kwe-hypochlorous acid. Ulwelwesi lwalusengozini yokulimala ezindaweni ezinomswakama-oketshezi, okwaholela ekubhobokeni kwegobolondo lensimbi.

3. Ukusetshenziswa kwe-GFRP Rebar kuma-Electrolyzer
3.1 Izici zeIbha ye-GFRP
I-GFRP rebar iyinto entsha ehlanganisiwe eyenziwe yi-pultrusion, isebenzisa i-glass fiber njenge-reinforcement kanye ne-epoxy resin njenge-matrix, kulandelwe ukuphiliswa kokushisa okuphezulu kanye nokwelashwa okukhethekile kwendawo. Le nto inikeza izakhiwo ezinhle kakhulu zemishini kanye nokumelana nokugqwala kwamakhemikhali okuvelele, ikakhulukazi idlula imikhiqizo eminingi ye-fiber ekumelana nezixazululo ze-asidi ne-alkali. Ngaphezu kwalokho, ayiqhubi, ayiqhubi ukushisa, ine-coefficient ephansi yokwanda kokushisa, futhi inokuqina okuhle nokuqina. Inhlanganisela ye-glass fiber kanye ne-resin ithuthukisa kakhulu ukumelana kwayo nokugqwala. Yilezi zakhiwo zamakhemikhali ezivelele ezenza kube yinto ekhethwayo yokuvikela ukugqwala kuma-electrolyzer.

Ngaphakathi kwe-electrolyzer, ama-rebar e-GFRP ahlelwe ngokuhambisana ngaphakathi kwezindonga zethangi, bese kuthiwa ukhonkolo we-vinyl ester resin phakathi kwawo. Ngemva kokuqina, lokhu kwakha isakhiwo esihlanganisiwe. Lo mklamo uthuthukisa kakhulu ukuqina komzimba wethangi, ukumelana nokugqwala kwe-asidi ne-alkali, kanye nezakhiwo zokuvimbela. Futhi kwandisa isikhala sangaphakathi sethangi, kunciphisa imvamisa yokugcinwa, futhi kwandise impilo yesevisi. Ifaneleka kakhulu ezinqubweni ze-electrolysis ezidinga amandla aphezulu kanye nokusebenza okuqinile.

3.3 Izinzuzo Zokusebenzisa i-GFRP Rebar kuma-Electrolyzer
Ukuvikelwa kokugqwala kwe-electrolyzer yendabuko kuvame ukusebenzisa izindlela zekhonkrithi ezibunjwe nge-resin. Kodwa-ke, amathangi ekhonkrithi asinda, anesikhathi eside sokuqina, aholela ekusebenzeni kahle kokwakhiwa endaweni, futhi avame ukuba nama-bubbles kanye nezindawo ezingalingani. Lokhu kungaholela ekuvuza kwe-electrolyte, kugqwalise umzimba wethangi, kuphazamise ukukhiqizwa, kungcolise imvelo, futhi kubangele izindleko eziphezulu zokulungisa. Ukusebenzisa i-GFRP rebar njengento yokulwa nokugqwala kunqoba ngempumelelo lezi zingqinamba: umzimba wethangi ulula, unamandla aphezulu okuthwala umthwalo, ukumelana okuhle kakhulu nokugqwala, kanye nezakhiwo ezinhle zokugoba nokuthamba. Ngesikhathi esifanayo, inikeza izinzuzo ezifana nomthamo omkhulu, impilo yesevisi ende, ukulungiswa okuncane, kanye nokulula kokuphakamisa nokuthutha.

4. Isifinyezo
Okusekelwe ku-epoxyIbha ye-GFRPIhlanganisa izakhiwo ezinhle kakhulu zemishini, zomzimba, kanye nezamakhemikhali zazo zombili izingxenye. Isetshenziswe kabanzi ukuxazulula izinkinga zokugqwala embonini ye-chlor-alkali kanye nasezindlini zekhonkrithi ezifana nemigudu, imigwaqo, kanye nama-bridge decks. Umkhuba ukhombisile ukuthi ukusebenzisa le nto kungathuthukisa kakhulu ukumelana nokugqwala kanye nempilo yesevisi yama-electrolyzer, ngaleyo ndlela kuthuthukiswe ukuphepha kokukhiqiza. Uma nje ukwakheka kwesakhiwo kunengqondo, ukukhethwa kwezinto kanye nezilinganiso kufanelekile, futhi inqubo yokwakha ijwayelekile, i-GFRP rebar ingathuthukisa kakhulu ukusebenza kwama-electrolyzer okulwa nokugqwala. Ngenxa yalokho, lobu buchwepheshe bunamathemba amaningi okusetshenziswa futhi bufanele ukukhuthazwa kabanzi.
