Ki sa ki eleman yo alyaj prensipal nan papye aliminyòm?
Eleman yo alyaj prensipal yo fè (Fe, 0.1-1%) ak Silisyòm (Si, 0.1-0.5%) amelyore fòs . Manganèz (Mn, 0.05-0.2%) ka ajoute pou amelyore pratik.} (<0.1%) occasionally appears for thermal stability. High-purity foils (e.g., 1145 alloy) maintain >99 . 4% aliminyòm kontni . eleman tras tankou Titàn (TI) rafine estrikti grenn pandan Distribisyon.
Ki jan fè kontni afekte pwopriyete papye?
Iron forms insoluble Al-Fe intermetallic compounds, increasing tensile strength. Excessive iron (>1%) diminye duktilite, sa ki lakòz fann pandan woule . optimal kont kontni (0.3-0.7%) balans fòs ak formability . li amelyore rezistans FOIL a pitting korozyon . fè tou diminye tanperati rkristalizasyon pandan anal {{}}.
Poukisa Silisyòm ajoute nan alyaj papye?
Silicon enhances hardness and reduces hot tearing during casting. It improves rolling efficiency by preventing sticking to rollers. Si content >0 . 3% Ogmante rezistivite elektrik FOIL a . Konbine avèk fè, li fòme al-Fe-Si faz pou estabilite . Foils manje-klas limite Si pou fè pou evite sifas brutality.
Ki sa ki enpurte yo kontwole nan papye wo-pite?
Copper dwe rete anba a 0 . 05% pou anpeche korozyon galvanik. Zenk (Zn) limite a<0.02% for medical packaging. Heavy metals like lead (Pb) and cadmium (Cd) are minimized per FDA standards. Oxygen content affects oxide layer uniformity. Tight control ensures compliance with ASTM B479.
Ki jan varyasyon alyaj enpak resiklaj?
Bouyon melanje-alyaj mande pou klasman yo kenbe nivo pite . fè-rich alyaj (e . g ., 8011) tolere plis resikle kontni {{6} pèmèt egzak separasyon alyaj . sistèm fèmen-bouk priyorite 1000/8000- alyaj seri pou efikasite .
