Iphrofayili ye-aluminium inezinhlobonhlobo zezicelo, kepha ngenxa yokwakheka kwayo okuhlukile kwe-alloy, kuzoba nzima ukulawula ukuqedwa kwenqubo ye-extrusion, ngaleyo ndlela izobangela ubuduli, ngocwaningo ukukhanya kwemikhiqizo yephrofayili ye-aluminium kungathuthukiswa kathathu. izici:
1. Isilinganiso sokwakheka kwengxubevange yezinto ezibonakalayo: khulisa okuqukethwe kwezinto zamakhemikhali ithusi ne-magnesium, isilinganiso esinconyiwe sithi: Si0.55-0.65, Fe<0.17, Cu0.3-0.35, Mg1.0-1.1.
2. Lawula inqubo ye-extrusion futhi uthuthukise izinga lokushisa le-outlet ye-extrusion yephrofayela ye-aluminium.Kunconywa ukuthi izinga lokushisa le-aluminium rod libe ngu-510-530 ℃ futhi izinga lokushisa le-outlet libe ngu-530-550℃.
3. Shintsha inqubo yokwelapha ngaphambilini yokudaya i-anodic oxidation, uwoyela wokucosha kuphela wamaphrofayili e-aluminium, hhayi ukugqwala kwe-alkali.
Phawula:
Ukumbozwa kwephrofayela ye-aluminium ngokuvamile kuvamise ukuba yimpuphu enamathelayo kanye nopende.
Ngomphumela okhanyayo nocwebezelayo:
1. Sebenzisa isibhamu esihle sokufutha, futhi uma inani lempushana yokufafaza liba likhulu, inkungu iba ngcono kakhulu (umphumela wokukhipha oyiyunifomu)
2. Isicwebezelisi esiphezulu (isicwebezelisi esingu-95 nangaphezulu) okuyimpushana (umbala ozikhethela sona) noma upende ngopende omuhle we-fluorocarbon
