Ma ke ʻano he ʻāpana lako koʻikoʻi i ka ʻoihana kemika, ua maʻalahi nā electrolyzers i ka pala ma muli o ka hōʻike lōʻihi ʻana i nā mea kemika, e hoʻopilikia maikaʻi ʻole ana i kā lākou hana, ke ola lawelawe, a me ka hoʻoweliweli ʻana i ka palekana hana. No laila, he mea nui ka hoʻokō ʻana i nā hana anti-corrosion kūpono. I kēia manawa, hoʻohana kekahi mau ʻoihana i nā mea e like me nā composites rubber-plastic a i ʻole ka vulcanized butyl rubber no ka pale ʻana, akā ʻaʻole maikaʻi nā hopena. ʻOiai he pono i ka hoʻomaka ʻana, ua emi nui ka hana anti-corrosion ma hope o 1-2 mau makahiki, e alakaʻi ana i ka pōʻino nui. Ke noʻonoʻo nei i nā kumu loea a me ka hoʻokele waiwai, ʻo Glass Fiber Reinforced Polymer (GFRP) rebar kahi koho kūpono no nā mea pale i ka pala i nā electrolyzers. Ma waho aʻe o ka loaʻa ʻana o nā waiwai mechanical maikaʻi loa,Paʻa GFRPhōʻike pū kekahi i ke kūpaʻa kemika koʻikoʻi i ka palaho, e loaʻa ana ka nānā nui ʻia mai nā ʻoihana ʻoihana chlor-alkali. Ma ke ʻano he hoʻokahi o nā mea pale i ka palaho i hoʻohana nui ʻia, kūpono loa ia no nā lako i hōʻike ʻia i nā media e like me ka chlorine, alkalis, hydrochloric acid, brine, a me ka wai. Hoʻolauna mua kēia ʻatikala i ka hoʻohana ʻana o ka GFRP rebar, me ka hoʻohana ʻana i ka fiber aniani ma ke ʻano he hoʻoikaika a me ka epoxy resin ma ke ʻano he matrix, i nā electrolyzers.

2. Ka nānā ʻana i nā kumu hōʻino ʻino i nā Electrolyzers
Ma waho aʻe o ka hoʻohuli ʻia e ka mea ponoʻī o ka electrolyzer, ka hoʻonohonoho ʻana, a me nā ʻano hana kūkulu, ʻo ka palaho ke kumu nui mai nā mea hoʻoheheʻe waho. ʻO kēia mau mea e komo pū me ke kinoea chlorine pulu wela kiʻekiʻe, ka hopena sodium chloride wela kiʻekiʻe, ka wai alkali i loaʻa i ka chlorine, a me ka mahu wai chlorine saturated wela kiʻekiʻe. Eia kekahi, hiki i nā kahe i hana ʻia i ka wā o ke kaʻina hana electrolysis ke hoʻolalelale i ka palaho. ʻO ke kinoea chlorine pulu wela kiʻekiʻe i hana ʻia i loko o ke keʻena anode e lawe i kahi nui o ka mahu wai. ʻO ka hydrolysis o ke kinoea chlorine e hana i ka waikawa hydrochloric corrosive kiʻekiʻe a me ka waikawa hypochlorous oxidizing ikaika. Hoʻokuʻu ka decomposition o ka waikawa hypochlorous i ka oxygen nascent. He hana kemika nui kēia mau mea, a koe wale nō ka titanium, ʻo ka hapa nui o nā mea metala a me nā mea ʻole metala e ʻeha nui i kēia kaiapuni. Ua hoʻohana mua kā mākou hale hana i nā pūpū kila i uhi ʻia me ka rubber paʻakikī maoli no ka pale ʻana i ka palaho. ʻO kona pae kū'ē wela he 0-80°C wale nō, ʻoi aku ka haʻahaʻa ma mua o ka mahana ambient o ke kaiapuni corrosive. Eia kekahi, ʻaʻole kū'ē ka rubber paʻakikī maoli i ka palaho waikawa hypochlorous. Ua maʻalahi ka lining i ka hōʻino ʻia i nā kaiapuni mahu-wai, e alakaʻi ana i ka perforation corrosive o ka pūpū metala.

3. Hoʻohana ʻia ʻana o GFRP Rebar i nā Electrolyzers
3.1 Nā ʻano oPaʻa GFRP
ʻO ka GFRP rebar kahi mea hui hou i hana ʻia e ka pultrusion, me ka hoʻohana ʻana i ka fiber aniani ma ke ʻano he hoʻoikaika a me ka epoxy resin ma ke ʻano he matrix, ukali ʻia e ka hoʻōla wela kiʻekiʻe a me ka mālama ʻili kūikawā. Hāʻawi kēia mea i nā waiwai mechanical maikaʻi loa a me ke kūpaʻa kemika corrosion koʻikoʻi, ʻoi aku ka maikaʻi ma mua o ka hapa nui o nā huahana fiber i ke kūpaʻa ʻana i nā hopena waikawa a me alkali. Eia kekahi, ʻaʻole ia he conductive, ʻaʻole he thermally conductive, he haʻahaʻa ka coefficient o ka hoʻonui thermal, a loaʻa iā ia ka elasticity a me ka paʻakikī maikaʻi. ʻO ka hui pū ʻana o ka fiber aniani a me ka resin e hoʻonui hou i kona kūpaʻa corrosion. ʻO kēia mau waiwai kemika koʻikoʻi e hoʻolilo iā ia i mea makemake ʻia no ka pale ʻana i ka corrosion i nā electrolyzers.

I loko o ka electrolyzer, ua hoʻonohonoho like ʻia nā rebars GFRP i loko o nā paia o ka pahu, a ua ninini ʻia ka sima resin vinyl ester ma waena o lākou. Ma hope o ka paʻa ʻana, hana kēia i kahi ʻano hoʻohui. Hoʻonui nui kēia hoʻolālā i ka paʻa o ke kino o ka pahu, ke kūʻē ʻana i ka pala waikawa a me ka alkali, a me nā waiwai insulation. Hoʻonui pū ia i ka hakahaka o loko o ka pahu, hoʻemi i ka pinepine o ka mālama ʻana, a hoʻolōʻihi i ke ola lawelawe. He kūpono loa ia no nā kaʻina hana electrolysis e koi ana i ka ikaika kiʻekiʻe a me ka hana tensile.

3.3 Nā Pōmaikaʻi o ka Hoʻohana ʻana i ka GFRP Rebar i nā Electrolyzers
Hoʻohana pinepine ka pale ʻana i ka palaho electrolyzer kuʻuna i nā ʻano hana sima resin-cast. Eia nō naʻe, he kaumaha nā pahu sima, he lōʻihi ka wā hoʻōla, hopena i ka hana kūkulu haʻahaʻa ma kahi, a he maʻalahi i nā pehu a me nā ʻili like ʻole. Hiki i kēia ke alakaʻi i ka electrolyte leakage, ka palaho ʻana i ke kino o ka pahu, ka hoʻopilikia ʻana i ka hana ʻana, ka haumia ʻana i ke kaiapuni, a me ka loaʻa ʻana o nā kumukūʻai mālama kiʻekiʻe. ʻO ka hoʻohana ʻana i ka GFRP rebar ma ke ʻano he mea anti-corrosion e lanakila pono ai i kēia mau hemahema: he māmā ke kino o ka pahu, he kiʻekiʻe ka hiki ke lawe i ka ukana, ke kūpaʻa maikaʻi loa i ka palaho, a me nā waiwai kūlou a me nā tensile kiʻekiʻe. I ka manawa like, hāʻawi ia i nā pono e like me ka nui o ka hiki, ke ola lawelawe lōʻihi, ka mālama liʻiliʻi, a me ka maʻalahi o ka hāpai ʻana a me ka lawe ʻana.

4. Hōʻuluʻulu Manaʻo
Hoʻokumu ʻia ma ka EpoxyPaʻa GFRPHoʻohui i nā waiwai mechanical, physical, a me kemika maikaʻi loa o nā ʻāpana ʻelua. Ua hoʻohana nui ʻia e hoʻoponopono i nā pilikia corrosion i ka ʻoihana chlor-alkali a i nā hale sima e like me nā tunnels, nā alanui, a me nā papahele alahaka. Ua hōʻike ʻia ka hoʻomaʻamaʻa ʻana e hiki i ka hoʻopili ʻana i kēia mea ke hoʻonui nui i ke kūpaʻa ʻana i ka corrosion a me ke ola lawelawe o nā electrolyzers, a laila e hoʻomaikaʻi ana i ka palekana hana. Inā kūpono ka hoʻolālā kūkulu, kūpono ke koho ʻana o nā mea a me nā ʻāpana, a ua hoʻohālikelike ʻia ke kaʻina hana kūkulu, hiki i ka GFRP rebar ke hoʻonui nui i ka hana anti-corrosion o nā electrolyzers. No laila, paʻa kēia ʻenehana i nā manaʻolana noi ākea a kūpono i ka hoʻolaha ākea.
