Aluminiumis inoshandiswa zvakanyanya mumaindasitiri akasiyana nekuda kwehuremu hwayo, kusimba, uye yakanakisa corrosion kuramba. Zvisinei, haina kudzivirirwa zvachose mukuora. Muchikamu chino, tichakurukura marudzi e-corrosion anokanganisa, uye nzira dzekudzivirira kuparara.

Sei Aluminium Corrosion Yakashata?

Aluminium inofarirwa mumashandisirwo akasiyana nekuda kwekuderera kwayo, ichiita kuti ireruke kupfuura mamwe simbi sesimbi. Iyo inozivikanwa zvakare neyakanakisa yekupisa uye yemagetsi conductivity zvivakwa. Nekudaro, inobatwa nemhando dzakasiyana dzekuora, kusanganisira gomba, galvanic, uye inter-granular corrosion. Pitting corrosion inoitika apo makomba madiki anoumba pamusoro pesimbi nekuda kwekusangana nenzvimbo dzine hukasha. Galvanic corrosion inoitika apo aruminiyamu inosangana nesimbi dzakasiyana pamberi pe electrolyte, ichigadzira sero rekuora. Inter-granular corrosion inokanganisa aruminiyamu alloys, ichideredza zvinhu pamwe nemiganhu yezviyo.

Mazano ekuti ungaita sei kudzivirira gomba

Kudzivirira aluminium corrosion, machira ekudzivirira anoshanda zvakanyanya.Anodizing, pendi, uye poda coatingkupa chipingamupinyi pakati pesimbi nemhoteredzo yayo inoparadza, kudzivirira unyoro uye zvimwe zvinoparadza zvisasvika pamusoro. Kugara uchicheneswa nesipo yakapfava nemvura kunogona kubvisa tsvina yaunganirwa netsvina, kudzivirira kukwira kwecorrosion. Makemikari anehasha uye abrasive cleaners anofanirwa kudziviswa sezvo anogona kukuvadza iyo inodzivirira layer.

Kuchengetedza aluminium kubva pakubata zvakananga nesimbi dzakasiyana kunoderedza njodzi yekuora kwegalvanic. Insulating zvinhu zvakaita sepurasitiki kana rubber gaskets zvinogona kushandiswa kudzivirira kusangana kwakananga pakati pealuminium nedzimwe simbi. Pamusoro pezvo, kudzora kuratidzwa kunzvimbo dzinoparadza kwakakosha. Kuita kufefetera zvakanaka uye kudzora mwando kunogona kuderedza mwando uye kuvapo kwemakemikari anoparadza kana magasi.

Mukupedzisa, nepo aluminium ine zvakawanda zvakanaka, inotapukirwa nekuora. Pitting, galvanic, uye inter-granular corrosion ndiwo marudzi akajairika anokanganisa aluminium. Kuisa marashi ekudzivirira, kuchengetedza hutsanana, kudzivirira kusangana nesimbi dzakasiyana, uye kudzora kuratidzwa kunzvimbo dzinoita ngura inzira dzinoshanda dzekudzivirira. Nekushandisa matanho aya, hupenyu uye kushanda kwealuminium kunogona kukwidziridzwa, kuve nechokwadi kuti inoenderera ichishandiswa mukushandisa kwakasiyana.

Kana iwe uine mimwe mibvunzo nezve kudzivirira aluminium corrosion, sunungukataura nesukudzidza zvakawanda. Kudzivirira inogara iri zano riri nani pane kubata nekuora kana yangopinda.
