Iindaba

I-Aluminiumis isetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yobunzima bayo, ukuqina, kunye nokumelana nokugqwesa okugqwesileyo. Nangona kunjalo, ayikhuselekanga ngokupheleleyo kwi-corrosion. Kweli nqaku, siza kuxubusha iintlobo ze-corrosion ezichaphazelayo, kunye neendlela zokuthintela ukubola.

Kutheni iAluminium Corrosion ingalunganga?

I-aluminiyam ithandwa kwizicelo ezahlukeneyo ngenxa yobuninzi bayo obuphantsi, iyenza ibe khaphukhaphu kunezinye iintsimbi njengentsimbi. Ikwayaziwa ngeempawu zayo ezibalaseleyo zobushushu kunye nombane. Nangona kunjalo, ichaphazeleka kwiindidi ezahlukeneyo zomhlwa, kubandakanya i-pitting, igalvanic, kunye ne-inter-granular corrosion. I-Pitting Corrosion yenzeke xa imingxuma emincinci ibumba kumphezulu wesinyithi ngenxa yokuvezwa kwimo engqongileyo enobundlobongela. I-galvanic corrosion yenzeke xa i-aluminiyam idibana neentsimbi ezingafaniyo phambi kwe-electrolyte, idala iseli yokubola. I-Inter-granular corrosion ichaphazela i-aluminium alloys, yenza buthathaka izinto eziphathekayo kunye nemida yeenkozo.

Iingcebiso malunga nendlela yokuphepha ukubola

Ukuthintela ukubola kwe-aluminium, iingubo ezikhuselayo zisebenza kakhulu.I-anodizing, ukupeyinta, kunye nokugquma umguboukubonelela ngomqobo phakathi kwesinyithi kunye nendalo yayo eyingozi, ukuthintela umswakama kunye nezinye izinto ezinobungozi ekufikeleleni phezulu. Ukucocwa rhoqo ngesepha ethambileyo kunye namanzi kunokususa ukungcola okuqokelelweyo kunye nokungcola, ukuthintela ukukhawuleza kokubola. Iikhemikhali ezinoburharha kunye nezicoci ze-abrasive kufuneka ziphetshwe njengoko zingonakalisa umaleko wokukhusela.

Ukukhusela i-aluminiyam ekudibaneni ngokuthe ngqo kunye neentsimbi ezingafaniyo kunciphisa umngcipheko we-galvanic corrosion. Izinto zokugquma ezifana neplastiki okanye iigasthi zerabha zingasetyenziselwa ukuthintela ukudibana ngokuthe ngqo phakathi kwealuminiyam kunye nezinye iintsimbi. Ukongeza, ukulawula ukuvezwa kwimo engqongileyo eyonakalisayo kubalulekile. Ukusebenzisa iindlela ezifanelekileyo zokungenisa umoya kunye nokulawula ukufuma kunokunciphisa amanqanaba okufuma kunye nobukho beekhemikhali ezidliwayo okanye iigesi.

Ukuqukumbela, ngelixa i-aluminiyam ineenzuzo ezininzi, ichaphazeleka kukuhlwa. I-pitting, igalvanic, kunye ne-inter-granular corrosion ziintlobo eziqhelekileyo ezichaphazela i-aluminium. Ukusebenzisa iingubo ezikhuselayo, ukugcina ucoceko, ukuphepha ukudibanisa neentsimbi ezingafaniyo, kunye nokulawula ukuvezwa kwindawo enobungozi ziindlela ezisebenzayo zokuthintela. Ngokuphumeza le milinganiselo, ixesha lokuphila kunye nokusebenza kwe-aluminium kunokwandiswa, ukuqinisekisa ukusetyenziswa kwayo okuqhubekayo kwizicelo ezahlukeneyo.

Ukuba uneminye imibuzo malunga nokuthintela ukubola kwe-aluminiyam, zikhululekeQhagamshelana nathiukufunda ngakumbi. Ukuthintela kuhlala kulicebo elingcono kunokujongana nomhlwa xa sele uqalile.
