Ubuchwepheshe bokuvikela i-Cathodic wuhlobo lobuchwepheshe bokuvikela i-electrochemical, obusebenzisa amandla angaphandle ebusweni besakhiwo sensimbi egqwalile. Isakhiwo esivikelwe siba yi-cathode, ngaleyo ndlela sicindezela ukufuduka kwe-electron okwenzeka ngesikhathi sokugqwala kwensimbi nokugwema noma ukunciphisa ukugqwala.

Ubuchwepheshe bokuvikela i-Cathodic bungahlukaniswa ngokuvikelwa komhlatshelo kwe-anode cathodic kanye nokuvikelwa kwamanje kwe-cathodic okuhlaba umxhwele. Lobu buchwepheshe buvuthiwe futhi busetshenziswa kabanzi ekulawuleni ukugqwala kwezakhiwo zensimbi njengamapayipi ensimbi, amaphampu amanzi, izintambo, izikhumulo zemikhumbi, imikhumbi, izinqe zamathangi, izipholile, njll. enhlabathini, emanzini olwandle, emanzini ahlanzekile, nasemithonjeni yamakhemikhali.

Ukuvikelwa kwe-anode yomhlatshelo kuyinqubo yokuxhuma izinsimbi ezimbili ngemisebenzi ehlukene futhi uzibeke ku-electrolyte efanayo. Insimbi esebenza kakhulu ilahlekelwa ama-electron futhi igqwalile, kuyilapho insimbi engasasebenzi kakhulu ithola ukuvikelwa kwama-electron. Ngenxa yokugqwala kwezinsimbi ezisebenza kakhulu phakathi nale nqubo, kubizwa ngokuthi ukuvikelwa kwe-anode cathodic yomhlatshelo.

Ukuvikelwa kwamanje kwangaphandle kwe-cathodic kufinyelelwa ngokushintsha amandla emvelo ezungezile ngokusebenzisa umthombo wamandla wangaphandle, ukuze amandla ezinto zokusebenza okufanele avikelwe ahlale ephansi kunaleyo ndawo ezungezile, ngaleyo ndlela ibe i-cathode yendawo yonke. Ngale ndlela, okokusebenza okuzovikelwa ngeke kugle ngenxa yokulahleka kwama-electron.

Isimiso sokusebenza

Sebenzisa ama-alloys ethusi ne-aluminium njengama-anode kanye nesistimu yempahla evikelekile njengama-cathodes. Ama-ion ethusi atholakala kuma-anode ethusi e-electrolyzing anobuthi futhi enza indawo enobuthi lapho exutshwe namanzi olwandle. I-electrolytic aluminium anode ikhiqiza i-Al3+, eyenza i-Al (OH) 3 ne-OH - ekhiqizwa yi-cathode. Lolu hlobo lwe-l (OH) 3 luhlanganisa ama-ion ethusi akhululiwe futhi lugeleza ohlelweni oluvikelekile ngamanzi olwandle. Inomthamo ophezulu wokukhanga futhi ingasakazeka ezindaweni ezinamanzi olwandle ahamba kancane lapho okuhlala khona izilwane zasolwandle, okuvimbela ukukhula kwazo. Lapho uhlelo lwe-aluminiyamu ye-anode yethusi lufakwa ngogesi emanzini olwandle, kwakheka ungqimba oluminyene lwe-calcium ne-magnesium endaweni engaphakathi yepayipi lensimbi njenge-cathode, futhi i-aluminium hydroxide colloid ekhiqizwa i-electrolysis igeleza ngamanzi olwandle, yakhe ifilimu evikelayo odongeni lwangaphakathi lwepayipi. Icwecwe le-calcium magnesium nefilimu ye-aluminium hydroxide colloidal ivimba ukusakazeka komoyampilo, ikhuphule i-polarization, futhi yehlise izinga lokugqwala, elingafinyelela inhloso yokunqanda ukubola nokuqeda ukugqwala.
