Ukupeyinta imiphezulu aluminiyam kufuna ingqalelo ngenyameko ubuchule kunye nemathiriyeli ukufezekisa ezihlala, iziphumo zobungcali. Nokuba ulungisa ifanitshala yangaphandle, ulungisa iindawo zemoto, okanye usebenza kwimizi-mveliso, ulungiselelo olululo kunye nesicelo kubalulekile ekuthinteleni i-oxidation, ukuqinisekisa ukunamathela, kunye nokwandisa ubomi bokuphela kwepeyintiwe. Esi sikhokelo sibanzi sibonelela ngengqiqo yeengcali kwiindlela ezisebenzayo zokupeyinta i-aluminium, ukusuka ekulungiseleleni umphezulu ukuya kulondolozo lwexesha elide.
Ukuqonda iAluminiyam Surfaces
ialuminiyam isetyenziswa kakhulu kulwakhiwo nakwimveliso ngenxa yokuqina kwayo, iipropathi ezikhaphukhaphu, kunye nokuxhathisa kwendalo kokubola. Nangona kunjalo, umphezulu wayo ogudileyo, ongenazimbobo kunye nomgangatho okhuselweyo okhuselweyo wenza ukuba kube ngumngeni ukuncamathela kwepeyinti. Umaleko obhityileyo owenziwe ngokwendalo kwi-aluminiyam ubonelela ngokhuseleko olugqwesileyo lomhlwa kodwa udala umqobo othintela ukudityaniswa kwepeyinti okufanelekileyo.
