Aluminium honeycomb core, raws li lub teeb yuag thiab siab - cov khoom siv hluav taws xob muaj zog, yuav tsum muaj cov txheej txheem tsim khoom los xyuas kom meej cov khoom zoo thiab kev ua tau zoo. Kab lus no qhia txog cov txheej txheem tsim ua haujlwm rau kev tsim kho-qib aluminium honeycomb cores.
1. Raw Khoom Npaj
Aluminium Foil Xaiv:
Siv 3003/5052 series aluminium alloy ntawv ci
Thickness: 0.03-0.1 hli
Tensile zog Ntau dua los yog sib npaug rau 150MPa
Pre-Kev kho mob:
Degreasing (alkaline kua, pH 9-11)
Tshuaj oxidation los tsim ib txheej 0.5-1μm oxide
Slitting:
Dav -cov ntawv foil (1200–1500mm) hlais rau hauv qhov dav dav (10–50mm)
2. Cov Txheej Txheem Txheej Txheem
Adhesive Txheej:
Hloov kho epoxy resin nplaum
Ob npaug - sab txheej: 8-12g / m²
Patterned roller hloov kom ntseeg tau tias uniformity
Lamination & Nias:
Kub: 120-150 degree
Siab: 0.8-1.2MPa
Duration: 30–60 minutes
Daim ntawv txheem hexagonal hlwb (sab ntev: 3-10mm)
Stretching & Curing:
Stretch ratio: 300-500%
Kev kho cua sov ib txhij (180℃× 2h)
3. Tshaj tawm -Kev ua haujlwm
Precision Txiav:
CNC waterjet txiav (± 0.2mm raug)
Qhov siab tshaj plaws vaj huam sib luag loj: 6000 × 1500mm
Kev kho saum npoo:
Anodizing (txheej thickness: 10-15μm)
PVDF txheej (3-coat, 2-ci txheej txheem)
Kev Xeem Zoo:
Flatwise compression zog (Ntau dua lossis sib npaug rau 1.5MPa)
Hluav taws kub tsis kam (GB8624 Class A2)
Thermal conductivity (tsawg dua los yog sib npaug rau 0.05W / (m·K))
4. Cov Kev Tswj Xyuas Zoo
Ib puag ncig: Tswj kub (23 ± 2 degree) thiab av noo (50 ± 5% RH)
Hauv - txheej txheem tshuaj xyuas: X-ray scanning kom muaj kev ncaj ncees
Kev pov thawj zaum kawg: Kev kuaj ntsev ntsev (2000 teev ib pob)
Kev lag luam yog nce mus rauntau hom ntawv (8m + panels).thiabthinner foils (0.02 hli)., thaum eco-cov dej phooj ywg-raws li cov nplaum tam sim no suav rau40% ntawm kev tsim khoom. Cov neeg tsim khoom paub txog cov txheej txheem no tau txais kev sib tw hauvfacades, qab nthab, thiab lwm yam kev siv architectural.
