Xa iimveliso zesinyithi zichatshazelwa ngumoya nomphunga wamanzi ixesha elide, kulula ukuba zibe sengozini yokubola okubangelwa yi-oxidative, nto leyo ebangela ukugqwala kumphezulu wesinyithi.
Ukuze kusonjululwe ingxaki yokubola kwesinyithi, abantu bayile ipeyinti yokulwa nomhlwa. Imigaqo yayo yokulwa nomhlwa ibandakanya ikakhulu umgaqo wokuthintela kunye nomgaqo wokukhusela i-cathodic.
Okokuqala, enye yemigaqo yokulwa nomhlwa yepeyinti yokulwa nomhlwa ngumgaqo wokuthintela. Ipeyinti yokulwa nomhlwa inezinto ezinokwenza ifilimu ekhuselayo. Le filimu ekhuselayo inokugubungela umphezulu wesinyithi, ivale umoya nomphunga wamanzi kwaye ithintele ekungcoleni isinyithi. Olu maleko wefilimu ekhuselayo udlala indima ekuhlukaniseni isinyithi kwindawo engaphandle, ngaloo ndlela wandisa ubomi benkonzo yeemveliso zesinyithi.
Omnye umgaqo wokuthintela umhlwa ngumgaqo wokukhusela i-cathodic. Ipeyinti yokulwa nomhlwa idla ngokuba nee-ion zesinyithi ezithile. Ezi i-ion zesinyithi zinokwenza umqobo okhuselayo we-electrochemical kumphezulu wesinyithi, ziguqule isinyithi sibe yi-anode, ngaloo ndlela zinciphisa impendulo ye-oxidation kumphezulu wesinyithi kwaye zinciphise izinga lokugqwala kwesinyithi. Le peyinti yokulwa nomhlwa inokwenza ukhuseleko lwe-cathodic njenge-zinc, i-aluminium kunye nezinye iisinyithi, ngaloo ndlela zifezekisa uthintelo olusebenzayo lwe-rust kwisinyithi.
Ngokubanzi, umgaqo wokulwa nomhlwa wepeyinti yokulwa nomhlwa ikakhulu ulibazisa ukwenzeka komhlwa wesinyithi ngokukhusela umqobo kunye ne-cathodic, kwaye ukhusela umgangatho kunye nobomi benkonzo yeemveliso zesinyithi. Ke ngoko, kwizicelo zobunjineli bokwenyani, kubaluleke kakhulu ukukhetha ipeyinti efanelekileyo yokulwa nomhlwa, enokwandisa ubomi beemveliso zesinyithi kwaye inciphise iindleko zokulungisa.
