Itekhnoloji yokukhusela i-Cathodic luhlobo lweteknoloji yokukhusela i-electrochemical, esebenzisa i-current current kwi-surface yesakhiwo sensimbi egqwesileyo. Ulwakhiwo olukhuselweyo luba yi-cathode, ngaloo ndlela lucinezela ukufuduka kwe-electron eyenzeka ngexesha lokubola kwesinyithi kunye nokuphepha okanye ukunciphisa ukwenzeka kwe-corrosion.

Itekhnoloji yokukhusela i-Cathodic inokwahlulwa ibe ngumbingelelo wokukhuselwa kwe-anode ye-cathodic kunye nokhuseleko lwangoku lwe-cathodic. Le teknoloji ikhulile kwaye isetyenziselwa ngokubanzi ukulawula ukuhlwa kwezakhiwo zetsimbi ezifana nemibhobho yentsimbi, iimpompo zamanzi, iintambo, amazibuko, iinqanawa, amazantsi etanki, izinto ezipholileyo, njl.

Ukukhuselwa kwe-anode yedini le-cathodic yinkqubo yokudibanisa iintsimbi ezimbini kunye nemisebenzi eyahlukeneyo kunye nokuyibeka kwi-electrolyte efanayo. Intsimbi esebenzayo ngakumbi ilahlekelwa zii-electron kwaye idliwe, ngelixa isinyithi esisezantsi sifumana ukhuseleko lwe-electron. Ngenxa yokubola kwezinyithi ezisebenza kakhulu ngexesha lale nkqubo, kubizwa ngokuba lukhuselo lwe-anode cathodic.

Ukhuseleko lwangoku lwangaphandle lwe-cathodic luphunyezwa ngokuguqula amandla okusingqongileyo ngomthombo wamandla wangaphandle, ukuze amandla esixhobo sokukhuselwa ahlale ephantsi kunommandla ongqongileyo, ngaloo ndlela ibe yi-cathode yendalo yonke. Ngale ndlela, izixhobo eziza kukhuselwa aziyi konakala ngenxa yokulahleka kwee-electron.

Umgaqo wokusebenza

Sebenzisa i-alloys yobhedu kunye ne-aluminium njenge-anodes kunye nenkqubo yezixhobo ezikhuselweyo njenge-cathodes. Iiyoni zobhedu ezifunyenwe kwi-electrolyzing copper anode ziyityhefu kwaye zenza indawo enetyhefu xa zixutywe namanzi olwandle. I-electrolytic aluminium anode ivelisa i-Al3 +, eyenza i-Al (OH) 3 kunye ne-OH - eveliswa yi-cathode. Olu hlobo lwe-l (OH) i-3 lufakela iiyoni zethusi ezikhutshiweyo kwaye zigeleza kwinkqubo ekhuselweyo ngamanzi olwandle. Inomthamo ophezulu we-adsorption kwaye inokusasazeka kwiindawo ezinamanzi olwandle acothayo apho zinokuhlala khona izinto eziphilayo zaselwandle, zithintele ukukhula kwazo. Xa inkqubo ye-aluminiyam ye-aluminiyam ye-anode ye-electrolyzed emanzini olwandle, umaleko oshinyeneyo we-calcium kunye ne-magnesium kwakheka kumphezulu ongaphakathi wombhobho wentsimbi njenge-cathode, kunye ne-aluminiyam hydroxide colloid eveliswa yi-electrolysis ihamba ngamanzi olwandle, yenze ifilimu ekhuselayo kudonga lwangaphakathi lombhobho. I-calcium magnesium coating kunye ne-aluminium hydroxide colloidal film ivimba ukusasazwa kweoksijini, yandisa i-polarization yoxinaniso, kwaye icothise isantya sokubola, esinokuthi sifezekise injongo ye-anti-corrosion kunye ne-anti-corrosion.
