Aluminium Sheet vs Aluminium Phaj: Thickness txhais thiab daim ntawv thov sib txawv
Aluminium Ntawv Thicknessyog thawj lub lim piam txhua tus neeg saib xyuas kev yuav khoom scrolls rau ntawm daim ntawv nug, tsis tau nws tseem yog qhov kev xaiv tsis raug tshaj plaws nyob rau hauv lub ntiaj teb aluminium lag luam.
Hauv qab no 6.35 mm (0.250 hauv.) cov khoom hu ua daim ntawv; saum toj no, lub tais.
Ib kab hauv ASTM B209, ISO 6361 thiab GB / T 3880 ua rau lub cascade ntawm metallurgical, logistical thiab kev lag luam qhov tshwm sim uas tuaj yeem ua rau nce siab - lossis deflate - qhov project nqi los ntawm ob tus lej feem pua.
Kab lus no dissect lub cascade, ntxiv plaub lub rooj sib piv siab, teb cov 12 cov lus nug feem ntau Googled los ntawm cov neeg yuav khoom, thiab qhia li cas Eco Alum Co., Ltd. txiav 1 680 t ntawm embodied CO₂ los ntawm kev hloov ntawm 10 mm plam 5 mm paj a 300 000 m² logistics ru tsev.
1. Ua li cas 6.35 mm? - Keeb kwm sau rau hauv tus lej
Hauv 1954 ASTM Committee B-07 xav tau kev txiav tawm kom pom tseeb rau qhov kub-dov muaj peev xwm ntawm 144-nti rov qab zeb tshiab.
¼ nti (6.35 mm) yog lub thinnest gauge uas yuav dov tsis muaj ntug kab nrib pleb ntawm tag nrho cov dav.
ISO luam qhov txwv hauv 1967 kom sib haum xeeb ntawm Atlantic thiab Pacific cov saw hlau.
Xya caum xyoo tom qab tus lej muaj sia nyob - tsis yog vim tias cov mills tsis tuaj yeem yob nyias cov ntsuas kub, tab sis vim hais tias txhua tus downstream code (vuam, UT, kub kho, qaug zog) yog calibrated rau nws.
2. Txheej txheem saw ntawm ib nrais muag
Daim ntaub (≤6.35 hli)
Txias-yob → Degrease → Anneal lossis tov-heat-kho → Tension-level → Trim → Eddy-tam sim no tshuaj xyuas → Chev lossis ntoo thawv.
Lub tais (>6.35 mm)
Kub-yob los yog DC-cam khwb cia → Scalp ob lub ntsej muag → Stretcher-theem (0.5-2 % yas lim) → 10 MHz ultrasonic soj ntsuam → Plasma los yog saw txiav → Stillage pob.
3. Microstructure & mechanical dhia
Cold-dov daim ntawv nqa pancaked grain nam piv ≥5:1, muab siab r-tus nqi rau kev sib sib zog nqus nqus tab sis qis dua tawg toughness.
Kub dov phaj recrystallizes rau hauv equiaxed nplej; loj grain loj nce yield zog tab sis triples yam tsawg kawg nkaus khoov vojvoog.
Lub rooj 1 ntsuas qhov dhia rau 6061-T6.

11. Daim ntawv txheeb xyuas - laminate qhov no rau koj phau ntawv sau
- Xam qhov xav tau seem modulus.
- Xaiv thinnest gauge ≤6.35 hli uas txaus siab deflection & buckling.
- Yog buckling kav, ntxiv stiffeners ua ntej dhia mus rau phaj.
- Tshawb xyuas vuam: yog tias phaj raug xaiv rau qaug zog, xav txog daim ntawv cog lus sandwich.
- Re-khiav carbon & tus nqi; daim ntawv yeej 70 % ntawm lub sijhawm.
12. Xaus - cia lub load hais lus, tsis yog tus cwj pwm
