Sonke siyayazi loo ntoIiprofayili ze-aluminium kwimizi-mvelisozizinto ze-alloy extrusion. Ukusebenza okungafanelekanga kwesinyathelo esinye kwimveliso kunye nenkqubo yokucubungula ngokulula kunokubangela umonakalo wezinto eziphathekayo kunye neziphene zomhlaba weprofayili. Umbala womphezulu weeprofayili eziqhelekileyo ze-aluminium kufuneka ube mhlophe osiliva. Apha ndiza kuthetha ngokufutshane malunga nezizathu zento etyheli ehlala isenzeka kumphezulu weprofayile ukongeza uburhabaxa kunye nobuthuntu.

Iprofayili yesilivere emhlophe ye-aluminium

Kukho izizathu ezibini eziphambili zokutyheli komphezulu weprofayile. Enye yindlela yokupholisa engafanelekanga ngexesha lenkqubo ye-extrusion yeprofayili, kwaye enye yindlela yonyango engafanelekanga yeprofayili. Uhlalutyo oluthile ngolu hlobo lulandelayo:

1. Iprofayili kufuneka ipholiswe emva kokuba ikhutshwe yi-die, ukwenzela ukuba kuphuculwe i-mechanical and physical properties. Isipholisi kufuneka sisetyenziswe kwinkqubo yokupholisa, kwaye izixhobo ezahlukeneyo zineziphumo ezahlukeneyo zokupholisa. Ezona zixhaphakileyo ngamanzi okanye i-oyile-based coolants. Ukuba amanzi asetyenziselwa ukupholisa okanye umlinganiselo wobhedu kwindawo yokupholisa mkhulu kakhulu, kulula ukwenza umphezulu weprofayile ujike ube tyheli. Isizathu sesokuba i-aluminiyam yinto esebenzayo yeekhemikhali zentsimbi, kwaye ithanda ukusabela kwiikhemikhali xa idibana nezinto ezisemoyeni nasemanzini.

2. Umphezulu weeprofayili ze-aluminium ye-industrial ifakwe kwifilimu ye-oxide, enokunyusa ukunyanzeliswa kwe-corrosion kunye ne-aesthetics ebusweni beeprofayili. Ngaphambi kokuba unyango oluphezulu lweprofayili, iprofayili ekhutshiweyo kufuneka icocwe ukususa ioli phezu komhlaba. Ukuba umphezulu weprofayili awucocwanga ngokufanelekileyo, kulula ukubangela ukuba ifilimu ye-oxide ibe nzima ukufaka umbala kwinkqubo elandelayo ye-oxidation, okanye umbala uya kungalingani, kwaye kuya kuba phuzi.
