Xa iimveliso zetsimbi zibonakaliswe kumoya womoya kunye nomphunga wamanzi ixesha elide, zichaphazeleka lula kwi-corrosion ye-oxidative, okubangela i-rust kwi-metal surface.
Ukuze kusonjululwe ingxaki yokubola kwesinyithi, abantu baqulunqa ipeyinti echasene nomhlwa.Imigaqo yayo yokuchasana nomhlwa ikakhulu ibandakanya umgaqo womqobo kunye nomgaqo wokukhusela we-cathodic.
Okokuqala, enye yemigaqo echasene ne-rust yepeyinti ye-anti-rust ngumgaqo wokuthintela.Ipeyinti ye-anti-rust iqulethe izinto ezinokuthi zenze ifilimu yokukhusela.Le filimu ekhuselayo inokugubungela umphezulu wesinyithi, ivalele umoya kunye nomphunga wamanzi kwaye ibathintele ekungcoleni isinyithi.Olu luhlu lwefilimu ekhuselayo ludlala indima ekuhlukaniseni isinyithi kwindawo yangaphandle, ngaloo ndlela ukwandisa ubomi benkonzo yeemveliso zetsimbi.
Omnye umgaqo wokuthintela umhlwa ngumgaqo wokukhusela i-cathodic.Ipeyinti ye-Antirust idla ngokuba nee-ion ezithile zetsimbi.Ezi ion zetsimbi zinokwenza umqobo okhuselayo we-electrochemical kumphezulu wesinyithi, ukuguqula isinyithi sibe yi-anode, ngaloo ndlela kuncitshiswe ukusabela kwe-oxidation kwindawo yesinyithi kunye nokunciphisa izinga lokubola kwesinyithi.Le peyinti yokuchasa umhlwa inokwenza ukhuseleko lwe-cathodic olufana ne-zinc, i-aluminiyam kunye nezinye iintsimbi, ngaloo ndlela ifezekisa uthintelo olusebenzayo lwentsimbi.
Ngokubanzi, umgaqo-anti-rust yepeyinti anti-umhlwa ikakhulu ulibazisa ukwenzeka intsimbi umhlwa ngokusebenzisa umqobo kunye nokhuseleko cathodic, kwaye ikhusela umgangatho kunye nobomi benkonzo yeemveliso zetsimbi.Ke ngoko, kwizicelo zobunjineli bokwenyani, kubaluleke kakhulu ukukhetha ipeyinti efanelekileyo echasene nomhlwa, enokwandisa ubomi beemveliso zetsimbi kunye nokunciphisa iindleko zokugcinwa.
