Icwecwe leAluminiyam vs iPleti yeAluminiyam: Ukutyeba Inkcazo kunye noMahluko weSicelo
I-Alumrium yephephasisihluzo sokuqala wonke umphathi wokuthenga uskrolela kwifomu yombuzo, kodwa iseyeyona parameter ikhethwe kakubi kurhwebo lwe-aluminiyam yehlabathi.
Ngezantsi 6.35 mm (0.250 kwi.) imveliso ibizwa ngokuba ishidi; ngaphezu kwayo, iplate.
Loo mgca omnye kwi-ASTM B209, ISO 6361 kunye ne-GB/T 3880 ibangela i-cascade ye-metallurgical, iziphumo zolungiselelo kunye nezorhwebo ezinokunyusa-okanye zithobe-iindleko zeprojekthi ngeepesenti ezinamadijithi amabini.
Eli nqaku licalula i-cascade, wongeza iitheyibhile ezine zokuthelekisa ezinezigqibo eziphezulu, iphendula i 12 imibuzo ehlala iGoogled ngabathengi, kwaye ibonisa indlela i-Eco Alum Co., Ltd. ilungisiwe 1 680 t ye-CO₂ equlethwe ngokutshintsha ukusuka 10 mm ipleyiti ukuya 5 mm iphepha kwi a 300 000 m² uphahla lolungiselelo.
1. Ngoba 6.35 mm? – Imbali ibhalwe kwinani
Ngaphakathi 1954 IKomiti ye-ASTM B-07 idinga ukunqunyulwa okucacileyo kokukwazi ukuqengqeleka kushushu kwi-144-intshi entsha yokubuyisela umva.
¼ intshi (6.35 mm) yayiyeyona geyiji ibhityileyo eyayinokuqengqeleka ngaphandle kweentanda kububanzi obupheleleyo.
I-ISO ikhuphele umda kwi 1967 ukulungelelanisa amakhonkco obonelelo ngeAtlantiki kunye nePasifiki.
Kwiminyaka engama-70 kamva eli nani lisaphila—kungekhona ngenxa yokuba izixhobo zokusila zingakwazi ukuqengqeleka zibe ncinane iigeyiji ezishushu, kodwa ngenxa yokuba yonke ikhowudi esezantsi (ilding, UT, ukunyanga ukushisa, ukudinwa) ilungelelaniswe kuyo.
2. Inkqubo chain ngokujonga nje
Iphepha (≤6.35 mm)
Ukuqengqeleka okubandayo → Ukwehlisa igrisi → I-Aneal okanye isisombululo-heat-cheat.
Iplate (>6.35 mm)
I-Hot-roll okanye i-DC-cast → Khuphuka ubuso bobabini → Inqanaba le-Stretcher (0.5–2 % ubunzima beplastiki) → 10 Ukuhlolwa kwe-ultrasonic MHz → iPlasma okanye isarha esikiweyo → Ipakethi yokumisa.
3. ULWAZI LWE & Ukutsiba koomatshini
Ishiti elipholileyo ithwala i-pancaked grain aspect ratio ≥5:1, inika ixabiso eliphezulu le-r kumzobo onzulu kodwa ukuqina kokwaphuka okusezantsi.
Ipleyiti eqengqelekisiweyo ijika ibe ziinkozo ezilinganayo; ubukhulu bengqolowa bunyusa amandla esivuno kodwa buphinda-phindwe kathathu ubuncinci beradiyasi.

11. Uluhlu lokukhangela lokuyila - laminate oku kwincwadi yakho yamanqaku
- Bala imodyuli yecandelo elifunekayo.
- Khetha eyona gauji i-thinnest ≤6.35 mm eyanelisa ukuphambuka & ukugquma.
- Ukuba i-buckling iyalawula, yongeza izinto eziqinileyo phambi kokuba utsibe epleyitini.
- Jonga iwelding: ukuba ipleyiti ikhethelwe ukudinwa, cinga ngesangweji yeshiti elidityanisiweyo.
- Sebenzisa kwakhona ikhabhoni & iindleko; sheet winile 70 % ixesha.
12. Isiphelo - vumela umthwalo uthethe, hayi umkhwa
NyangaI-Alumrium yephephanjengenguqu yasimahla, hayi umbhalo osemazantsi welifa.
I 6.35 mm umda uvula amakhonkco obonelelo amabini ahambelanayo anexabiso elahlukileyo, ikhabhoni kunye neenyawo zexesha elikhokelayo.
Qala yonke iprojekthi ngeTheyibhile 3 kunye noluhlu lokutshekisha lwe-Eco Alum; 30-50 % ukugcinwa kwezinto eziphathekayo kunye neeveki zeshedyuli ziyisiqhelo.
