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

2. Nānā i nā mea pōʻino ʻino ma nā Electrolyzers
Ma waho aʻe o ka hoʻohuli ʻia ʻana e ka mea electrolyzer ponoʻī, ka hoʻolālā, a me nā ʻenehana kūkulu ʻana, ʻo ka corrosion ke kumu nui mai nā media corrosive waho. ʻO kēia mau mea e pili ana i ke kinoea chlorine pulu kiʻekiʻe, ka solution sodium chloride kiʻekiʻe, ka waiʻona alkali i loko o ka chlorine, a me ka mahu wai chlorine saturated kiʻekiʻe. Eia kekahi, hiki i nā au hele hewa i hana ʻia i ka wā o ke kaʻina electrolysis hiki ke hoʻolalelale i ka corrosion. ʻO ke kinoea chlorine pulu kiʻekiʻe i hana ʻia i loko o ke keʻena anode e lawe i ka nui o ka mahu wai. ʻO ka hydrolysis o ke kinoea chlorine e hoʻohua ai i ka waika hydrochloric corrosive a me ka ikaika oxidizing hypochlorous acid. ʻO ka decomposition o hypochlorous acid e hoʻokuʻu i ka oxygen nacent. ʻO kēia mau mea hoʻolaha kemika, a koe wale nō ka titanium, ʻo ka hapa nui o nā mea metala a me nā mea hao ʻole e loaʻa i ka ʻino nui i kēia kaiapuni. Ua hoʻohana mua kā mākou mea kanu i nā pūpū kila i hoʻopaʻa ʻia me ka ʻōpala paʻa maoli no ka pale ʻana i ka ʻino. ʻO 0-80°C wale nō kona pae pale wela, ʻoi aku ka haʻahaʻa ma mua o ka mahana ambient o ke kaiapuni corrosive. Eia kekahi, ʻaʻole kūpaʻa ka lāʻau paʻa maoli i ka corrosion acid hypochlorous. Hiki ke hoʻopōʻino ʻia ka ʻili i loko o nā wahi mahu-wai, e alakaʻi ana i ka perforation corrosive o ka pūpū metala.

3. Ke noi o GFRP Rebar ma Electrolyzers
3.1 Nā ʻano oGFRP Rebar
ʻO ka GFRP rebar he mea hoʻohui hou i hana ʻia e ka pultrusion, me ka hoʻohana ʻana i ka fiber aniani e like me ka hoʻoikaika a me ka resin epoxy e like me ka matrix, a ukali ʻia e ka mālama wela kiʻekiʻe a me ka mālama ʻana i ka ʻili kūikawā. Hāʻawi kēia mea waiwai i nā waiwai mechanical maikaʻi loa a me ke kūʻē ʻana i ka corrosion kemika, ʻoi aku ka maikaʻi o ka nui o nā huahana fiber i ke kūʻē ʻana i ka waika a me ka hopena alkali. Eia kekahi, ʻaʻole ia e hoʻokō, non-thermally conductive, he haʻahaʻa haʻahaʻa o ka hoʻonui wela, a loaʻa iā ia ka elasticity maikaʻi a me ka paʻakikī. ʻO ka hui pū ʻana o ka fiber aniani a me ka resin e hoʻonui i kona kūpaʻa corrosion. ʻO kēia mau waiwai kemika koʻikoʻi ka mea i makemake ʻia no ka pale corrosion i nā electrolyzers.

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

3.3 Nā Pono o ka hoʻohana ʻana i ka GFRP Rebar i nā Electrolyzers
Hoʻohana pinepine ʻia ka pale corrosion electrolyzer kuʻuna. Eia nō naʻe, kaumaha nā pahu kaʻa, lōʻihi nā manawa hoʻōla, ka hopena haʻahaʻa o ka hana ʻana ma ka pūnaewele, a hiki i nā ʻōhū a me nā ʻili like ʻole. Hiki i kēia ke alakaʻi i ka leakage electrolyte, ʻino i ke kino pahu, hoʻopau i ka hana ʻana, hoʻohaumia i ke kaiapuni, a hoʻonui i nā kumukūʻai mālama. ʻO ka hoʻohana ʻana i ka GFRP rebar ma ke ʻano he mea anti-corrosion e lanakila pono ana i kēia mau drawbacks: māmā ke kino o ka pahu, he kiʻekiʻe ka haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o ka corrosion, a me ka ʻoi aku o ka piko a me nā waiwai tensile. I ka manawa like, hāʻawi ia i nā pono e like me ka mana nui, ke ola lawelawe lōʻihi, ka mālama liʻiliʻi, a me ka maʻalahi o ka huki a me ka lawe ʻana.

4. Hōʻuluʻulu manaʻo
Hoʻokumu ʻia ka epoxyGFRP rebarhoʻohui i nā waiwai mechanical, kino, a me kemika maikaʻi o nā mea ʻelua. Ua hoʻohana nui ʻia e hoʻoponopono i nā pilikia corrosion i ka ʻoihana chlor-alkali a me nā hale paʻa e like me nā tunnels, pavements, a me nā alahaka. Ua hōʻike ka hoʻomaʻamaʻa ʻana i ka hoʻohana ʻana i kēia mea hiki ke hoʻonui nui i ke kūpaʻa corrosion a me ke ola lawelawe o nā electrolyzers, e hoʻomaikaʻi ai i ka palekana hana. Hāʻawi ʻia ka hoʻolālā hoʻolālā kūpono, kūpono ke koho ʻana a me nā ʻāpana, a ua hoʻohālikelike ʻia ke kaʻina hana, hiki i ka GFRP rebar ke hoʻonui nui i ka hana anti-corrosion o nā electrolyzers. No laila, paʻa kēia ʻenehana i nā manaʻo noiʻi ākea a kūpono i ka hoʻolaha ākea.
