Covthickness ntawm hnyav luag hauj lwm aluminium ntawv ciyog ib qho tseem ceeb tshaj plaws uas txiav txim siab nwsmechanical zog, kua muag kuj, puncture kuj, thiab tag nrho haum rau kev lag luam kev siv. Cov neeg siv khoom lag luam, suav nrogzaub mov processors, ntim converters, rwb thaiv tsev manufacturers, thiab export packagers, cia siab rau qhov tseeb thickness specifications los xyuas kom meejdurability thiab kev ua haujlwm zoo ib yam.
Hom Thickness Range
| Foil Hom | Thickness (hli) | Thickness (Microns / µm) |
|---|---|---|
| Standard Aluminium Ntawv Nyiaj | 0.009 – 0.012 | 9 – 12 µm |
| Heavy Duty Aluminium Ntawv Nyiaj | 0.015 – 0.025 | 15 – 25 µm |
| Ntxiv Heavy Duty / Industrial Foil | 0.030 – 0.050 | 30 – 50 µm |
Nco tseg:Rau cov ntawv thov kev lag luam, ntawv ci hauv qab 15 µm feem ntau yogtsis pom zoo due to lower puncture and tear resistance. Extra heavy duty foil (>30 µm) yog siv rausiab -load wrapping, rwb thaiv tsev, thiab export ntim.
Yam Uas Txiav Txim Thickness Xaiv
Thaum xaiv lub luag haujlwm hnyav aluminium foil thickness rau cov ntawv thov kev lag luam, xav txog:
Mechanical Load
Thicker foil resiststearing thiab xuas nrig ntausthaum tuav lossis qhwv cov khoom hnyav.
Thermal Requirements
Ntawv ci siv rauci, ci, los yog siab -kub muaj txheej txheemxav tau ntau dua thickness kom muaj kev ruaj ntseg.
Barrier & Ntim Xav Tau
Thicker foil txopinholesthiab txhim khonoo noo, oxygen, thiab lub teeb barrier kev ua tau zoo, tseem ceeb rauzaub mov thiab tshuaj ntim khoom.
Lamination & Txheej
Laminated lossis coated foils rau kev siv feem ntau xav tau15-30 µm cov ntawv citxhawb nqantawv, PE, lossis cov yeeb yaj kiab tshwj xeebtsis muaj kev cuam tshuam lub zog.
Common Alloy Qib rau Industrial Heavy Duty Foil
Cov ntawv thov kev lag luam feem ntau siv cov alloys ua kelub zog, yooj, thiab corrosion kuj, suav nrog:
1050 / 1060- High purity, zoo heev corrosion kuj, haum rau zaub mov- hais txog daim ntawv thov
1100 / 1145- Mos, yoog raws, dav siv hauv cov dej num hnyav laminated ntawv
1235- Tsawg impurity cov ntsiab lus, zoo tagnrho rau laminates thiab coated lug
3003 / 3004- Manganese- ntxiv, ntau dua txhua yam muaj zog rau kev lag luam thiab kev siv rwb thaiv tsev
8011- Sib npaug lub zog thiab thaiv cov khoom rau siab - kawg ntim thiab xa tawm daim ntawv thov
Temper thiab Mechanical Considerations
O Temper (Soft):Feem ntau rau qhwv, folding, thiab sib sau
H22 / H24 (Semi-Hard):Muabsiab zog thiab kua muag kuj, haum rau industrial thiab export ntim
H18 / H19 (Nruab):Tsis tshua muaj siv nyob rau hauv cov txheej txheem muaj ntawv ci tab sis yuav siv tau rau hauv laminated los yog reinforced ntawv ci
Thickness Tswj & Standards
Heavy luag hauj lwm muaj txhuas ntawv ci yog tsim nrognruj thickness kam rau ua, feem ntau hauv±3–5%, kom paub meej:
Uniform barrier zog
Smooth lamination
Kev ua tau zoo txhua yam
Cov qauv feem ntau hais txog suav nrogASTM B-479, EN 485-2, ISO 6361, uas txhaistso cai thickness ranges, kam rau ua, thiab mechanical xav tau.
Kev Xaiv Cov Kev Qhia rau Cov Neeg Yuav Khoom
Thaum muab lub luag haujlwm hnyav aluminium ntawv ci rau kev siv:
Qhia thickness nyob rau hauvmicrons (µm)rau qhov raug
Xav txogdaim ntawv thov load thiab kub yuav tsum tau
Xaiv cov qib alloy tsim nyog raulub zog thiab corrosion kuj
Confirm temper raumechanical kev ua tau zoo
Txheeb xyuaskev ua raws li tus neeg yuav khoomnrog cov qauv thoob ntiaj teb thiab kev tswj xyuas zoo
Xaus
Raucov ntawv thov kev lag luam, hnyav luag hauj lwm aluminium ntawv nyiaj feem ntau yog los ntawm15–25 µm, nrogntxiv hnyav hnyav ntawv ci mus txog 50 µmrau siab -load, siab- kub, los yog laminated siv. Kev xaiv thickness kom raugdurability, kev ua tau zoo, thiab tus nqi -efficiency, ua nws ib qho tseem ceeb parameter raukev lag luam chav ua noj, ntim khoom lag luam, rwb thaiv tsev, thiab xa tawm -kev ua haujlwm taw qhia.
