1. Intshayelelo
Njengesixhobo esibalulekileyo kushishino lweekhemikhali, ii-electrolyzers zisengozini yokugqwala ngenxa yokuvezwa ixesha elide kwi-chemical media, nto leyo echaphazela kakubi ukusebenza kwazo, ubomi benkonzo, kwaye isongela ngakumbi ukhuseleko lwemveliso. Ke ngoko, ukusebenzisa amanyathelo asebenzayo okulwa nokugqwala kubalulekile. Okwangoku, amanye amashishini asebenzisa izinto ezifana nee-composites zerabha-plastiki okanye irabha ye-butyl evulcanized ukukhusela, kodwa iziphumo zihlala zinganeliseki. Nangona zisebenza ekuqaleni, ukusebenza kokulwa nokugqwala konakala kakhulu emva kweminyaka eli-1-2, nto leyo ekhokelela kumonakalo omkhulu. Xa kujongwa zombini izinto zobugcisa kunye nezoqoqosho, i-Glass Fiber Reinforced Polymer (GFRP) rebar lukhetho olufanelekileyo lwezinto ezilwa nokugqwala kwi-electrolyzers. Ngaphandle kokuba neempawu ezintle zoomatshini,I-GFRP rebarikwabonisa ukumelana okubalaseleyo nokugqwala kweekhemikhali, nto leyo efumana ingqalelo ebanzi kwiinkampani zoshishino lwe-chlor-alkali. Njengenye yezona zinto zisetyenziswa kakhulu ekumelaneni nokugqwala, ifanelekile ngakumbi kwizixhobo ezivezwe kwiindawo ezifana ne-chlorine, i-alkalis, i-hydrochloric acid, i-brine, kunye namanzi. Eli nqaku lizisa ngokuyintloko ukusetyenziswa kwe-GFRP rebar, kusetyenziswa i-glass fiber njenge-reinforcement kunye ne-epoxy resin njenge-matrix, kwi-electrolyzers.

2. Uhlalutyo lwezinto ezibangela umonakalo kwi-electrolyzers
Ngaphandle kokuphenjelelwa zizinto ze-electrolyzer, ulwakhiwo, kunye neendlela zokwakha, ukugqwala ngokuyintloko kuvela kwimidiya yangaphandle egqwalisayo. Ezi ziquka igesi ye-chlorine emanzi enobushushu obuphezulu, isisombululo se-sodium chloride esinobushushu obuphezulu, utywala be-alkali obune-chlorine, kunye nomphunga wamanzi we-chlorine ogcwele ubushushu obuphezulu. Ngaphezu koko, imisinga elahlekileyo eveliswa ngexesha lenkqubo ye-electrolysis inokukhawulezisa ukugqwala. Igesi ye-chlorine emanzi enobushushu obuphezulu eveliswa kwigumbi le-anode ithwala umphunga wamanzi omninzi. I-hydrolysis yegesi ye-chlorine ivelisa i-hydrochloric acid egqwalisayo kakhulu kunye ne-hypochlorous acid enamandla. Ukubola kwe-hypochlorous acid kukhupha ioksijini esandula ukuzalwa. Ezi midiya zisebenza kakhulu kwiikhemikhali, kwaye ngaphandle kwe-titanium, uninzi lwezinto zesinyithi nezingezizo zesinyithi zithwaxwa kukugqwala okukhulu kule ndawo. Isityalo sethu ekuqaleni sasisebenzisa amaqokobhe esinyithi agqunywe ngerabha eqinileyo yendalo ukukhusela ukugqwala. Uluhlu lwayo lokumelana nobushushu lwaluyi-0–80°C kuphela, oluphantsi kunobushushu obuqhelekileyo bendawo egqwalisayo. Ngaphezu koko, irabha eqinileyo yendalo ayixhathisi ukugqwala kwe-hypochlorous acid. Ingaphakathi lalinokonakala kwiindawo ezishushu nomphunga, nto leyo eyabangela ukuba iqokobhe lesinyithi ligqobhoke.

3. Ukusetyenziswa kwe-GFRP Rebar kwii-Electrolyzers
3.1 Iimpawu zeI-GFRP Rebar
I-GFRP rebar yinto entsha edityanisiweyo eyenziwe yi-pultrusion, isebenzisa i-glass fiber njenge-reinforcement kunye ne-epoxy resin njenge-matrix, ilandelwa kukuphiliswa kobushushu obuphezulu kunye nonyango olukhethekileyo lomphezulu. Le nto inika iipropati ezibalaseleyo zoomatshini kunye nokumelana nokugqwala kweekhemikhali okubalaseleyo, ngakumbi ukwenza ngcono iimveliso zefayibha ekuchaseni izisombululo ze-asidi kunye ne-alkali. Ukongeza, ayiqhubi, ayiqhubi ubushushu, inomlinganiselo ophantsi wokwandiswa kobushushu, kwaye inokuqina okuhle kunye nokuqina. Ukudibanisa i-glass fiber kunye ne-resin kuphucula ngakumbi ukumelana kwayo nokugqwala. Zizo kanye ezi mpawu zibalulekileyo zeekhemikhali ezenza ukuba ibe yinto ekhethwayo yokukhusela ukugqwala kwii-electrolyzers.

Ngaphakathi kwi-electrolyzer, ii-GFRP rebar zicwangciswe ngaxeshanye ngaphakathi kweendonga zetanki, kwaye i-vinyl ester resin concrete igalelwa phakathi kwazo. Emva kokuqina, oku kwenza isakhiwo esidibeneyo. Olu yilo luphucula kakhulu ukuqina komzimba wetanki, ukumelana nokugqwala kwe-asidi kunye ne-alkali, kunye neepropati zokuthintela ukugquma. Kwakhona kwandisa indawo yangaphakathi yetanki, kunciphisa amaxesha okugcinwa, kwaye kwandisa ubomi benkonzo. Ifanelekile ngokukodwa kwiinkqubo ze-electrolysis ezifuna amandla aphezulu kunye nokusebenza okuxineneyo.

3.3 Iingenelo zokusebenzisa i-GFRP Rebar kwii-Electrolyzers
Ukhuseleko lokugqwala kwe-electrolyzer yendabuko ludla ngokusebenzisa iindlela zekhonkrithi ezenziwe nge-resin. Nangona kunjalo, iitanki zekhonkrithi zinzima, zinexesha elide lokuzinza, zibangela ukusebenza okuphantsi kolwakhiwo kwindawo, kwaye zidla ngokuba namaqamza kunye nemiphezulu engalinganiyo. Oku kunokukhokelela ekuvuthweni kwe-electrolyte, ukugqwala umzimba wetanki, ukuphazamisa imveliso, ukungcolisa okusingqongileyo, kunye neendleko eziphezulu zokulungisa. Ukusebenzisa i-GFRP rebar njengesixhobo sokulwa nokugqwala kuyazoyisa ngempumelelo ezi ngxaki: umzimba wetanki ulula, unomthamo ophezulu wokuthwala umthwalo, ukumelana nokugqwala okugqwesileyo, kunye neempawu ezigqwesileyo zokugoba kunye nokuxinana. Kwangaxeshanye, inika izibonelelo ezinje ngomthamo omkhulu, ubomi benkonzo ende, ulondolozo oluncinci, kunye nokulula kokuphakamisa kunye nokuthuthwa.
