Kana zvigadzirwa zvesimbi zvakaratidzwa kumhepo uye mvura mhute kwenguva yakareba, zviri nyore kubatwa neoxidative corrosion, zvichikonzera ngura pamusoro pesimbi.
Kuti vagadzirise dambudziko rekuora kwesimbi, vanhu vakagadzira pendi inorwisa ngura.Nheyo dzayo dzekurwisa ngura dzinonyanya kusanganisira chipingamupinyi musimboti uye cathodic kudzivirira musimboti.
Chekutanga pane zvese, imwe yeanopesana nerust misimboti yeanti-ngura pendi ndiyo inodzivirira musimboti.Anti-rust pendi ine zvinhu zvinogona kugadzira firimu rinodzivirira.Iyi firimu inodzivirira inogona kuvhara pamusoro pesimbi, ichivharira mweya uye mhute yemvura uye ichidzivirira kubva pakuora simbi.Iyi firimu yekudzivirira inoita basa rekuparadzanisa simbi kubva kune imwe nzvimbo yekunze, nekudaro kuwedzera hupenyu hwebasa rezvigadzirwa zvesimbi.
Imwe nheyo yekudzivirira ngura ndiyo nheyo ye cathodic kudzivirira.Pendi yeAntirust kazhinji ine mamwe maion simbi.Aya maion esimbi anogona kugadzira chinodzivirira che electrochemical barrier pamusoro pesimbi, kushandura simbi kuita anode, nekudaro ichidzikisa oxidation reaction pamusoro pesimbi uye kuderedza kukora kwesimbi.Iyi pendi inorwisa ngura inogona kugadzira cathodic kudzivirira senge zinc, aluminium uye mamwe masimbi, nekudaro kuwana inoshanda kudzivirira ngura kwesimbi.
Kazhinji, iyo anti-ngura musimboti wependi inorwisa ngura inonyanya kunonoka kuitika kwesimbi ngura kuburikidza ne barriers uye cathodic kudzivirira, uye inodzivirira kunaka uye hupenyu hwebasa rezvigadzirwa zvesimbi.Naizvozvo, mumashandisirwo einjiniya chaiwo, zvakakosha kwazvo kusarudza pendi yakakodzera yekudzivirira ngura, iyo inogona kuwedzera hupenyu hwezvigadzirwa zvesimbi uye kuderedza mari yekugadzirisa.
