Inguva yakareba sei aluminium oxidize uye corrode mushure mekushandisa?
Chinhu chikuru chealuminium ialuminium uye chikamu chiduku chezvikamu zvealloy. Vamwe vanhu vanofunga kuti aluminium haisi nyore kuisa oxidize nekuti pave paine shanduko shoma muvara. Muchokwadi, aluminium isimbi inoshanda kwazvo, iri nyore kuita oxidize pane iron. Chikonzero nei isingaonekwe imhaka yekuti iyo aluminium oxide yakaumbwa mushure meiyo oxidation haina ruvara uye yakajeka. Uye iyi dhizaini yeoxide firimu inotsaura iyo yemukati aruminiyamu uye kubatwa kwemhepo, saka haizoramba ichiwedzera oxidize, uye nekudaro kudzivirira iyo aluminium substrate. Saka aluminium inogara yakasimba kunyangwe isina kurapwa kwepamusoro.
Asi iyo oxide firimu haipindike, aluminium oxide inoshanda kune asidhi uye alkali, munzvimbo ine mhepo inoparadza, iyo oxide firimu inoparadzwa nyore nyore, zvichikonzera kuora kwealuminum substrate, kukuvara. Kana ikashandiswa panze, kuratidzwa kwezuva, uye mvura inonaya ine acid inoita kuti kuora kwearuminiyamu kuwedzere. Saka inguva yakadii iyo aluminium mbiri ichave oxidize uye corrode kana ikashandiswa zvinoenderana nenharaunda uye nepamusoro pekurapa kwayo. Kugadziriswa kwepamusoro kwealuminium profiles kunosanganisira anodic oxidation, electrophoresis, spraying, electroplating, nezvimwewo inopesana nekuora kunyange munzvimbo yakaoma yekunze, uye hupenyu hwebasa rekuchengetedza hunogona kusvika makore makumi maviri nemashanu.
