8011 Aluminium Ntawv Nyiaj 90μm Rau Cov Cuab Yeej|HVAC Barrier

1. Taw qhia

8011 aluminium foil 90MIC rau cov pa duct yog qhov siab -kev ua tau zoo, hnyav- cov khoom siv tau teev tseg rau kev tsim cov khoom siv hluav taws xob zoo.

Cov qib tshwj xeeb no, feem ntau hu ua "heavy gauge" foil, yog tsim los ua kom muaj kev txhim kho tseem ceeb hauv kev ua haujlwm zoo tshaj tus qauv, nyias nyias.

Cov8011 : 10000000000000000000;, ib qho txhuas- hlau- silicon muaj pes tsawg leeg, muaj cov hauv paus ntawm lub zog zoo thiab kev tsim kho.

Cov90μm (0.09mm) tuabdramatically txhim kho qhov no, xa superiorpuncture thiab kua muag kuj, txhim kho cov qauv kev ncaj ncees kom zoo dua qub tuav, thiab ib qho zoopinhole-dawbnto rau guaranteed huab cua thiab noo noo barrier kev ua tau zoo.

Feem ntau muab nkag rau hauv qhov muag muag'O' (annealed) npau tawsrau qhov kev hloov pauv siab tshaj plaws, cov khoom siv no yog qhov kev xaiv zoo tshaj plaws rau kev thov HVAC daim ntawv thov hauv cov tsev lag luam, muaj qhov cua, thiab qhov chaw huv huv, qhov ntev -lub sij hawm durability, system efficiency, thiab kev nyab xeeb yog qhov tseem ceeb.

2. Tshuaj muaj pes tsawg leeg thiab cov khoom ntawm 8011 Aluminium Foil

2.1 Tshuaj muaj pes tsawg leeg

Lub 8011 aluminium alloy belongs rau Al-Fe-Si system, nrog kev tswj xyuas meej meej txiav txim siab nws qhov haum rau HVAC daim ntawv thov.

Qhov tshwj xeeb alloy rau ASTM B209 thiab GB / T 3190 tsim cov kab hauv qab no

2.2 Temper thiab Mechanical Properties

Rau daim ntawv thov cua duct, 8011 ntawv ci yog yuav luag ib txwm muab nkag rau hauv'O' (tag nrho annealed) npau taws.

Lub 'O' Temper:Qhov no yog qhov softest, feem ntau ductile xeev ntawm cov hlau, uas yog qhov tseem ceeb rau kev tsim cov ducts saj zawg zog.

Nws tso cai rau cov ntawv ci tau yooj yim laminated, corrugated, thiab helically raug mob nyob ib ncig ntawm lub steel hlau ncej yam tsis muaj cracking.

2.3 90 µm thickness optimization

Vim li cas 90 µm (0.09 mm) feem ntau tau teev tseg rau cov kav dej:

Mechanical robustness:90 µm resists tearing thaum tuav, crimping thiab seaming zoo dua li nyias nyias (xws li, 6-25 µm).

Vapor thiab puncture Performance:Cov ntawv ci tuab yog tsawg dua los tsim cov pinholes hauv kev tsim thiab kev teeb tsa; raws li ib qho kev thaiv tsis zoo nws muab ze rau - xoom vapor kis.

Formability balance:ntawm 90 µm cov ntawv ci tseem khoov thiab tsim tau yooj yim rau lub luj tshib, seams thiab dab tshos yam tsis muaj caij nplooj ntoos hlav ntau dhau -rov qab los yog tawg thaum siv khoov radii thiab cov cuab yeej.

Economic & hnyav tradingoff:muab qhov yuav tsum tau ua kom ruaj khov rau feem ntau HVAC systems tsis muaj cov khoom siv thiab tuav cov nqi ntawm cov ntawv ci + cov ntawv tuab hlau. Qhov ntom ntom ~ 2.7 g / cm³ → 90 µm coil hnyav ≈ 2.43 kg ib m² ntawm ib qho - sab ntawv ci.

Cov kev ua tau zoo tshwj xeeb feem ntau teeb tsa tuab ± 5% (piv txwv li, 85.5–94.5 µm) tshwj tsis yog qhov project tej yam kev mob hu rau kev tswj nruj dua.

3. Kev tsim cov txheej txheem ntawm 90μm 8011 Aluminium Foil

3.1 Casting thiab Rolling

Kev tsim tawm ntawm 90μm 8011 ntawv ci rau HVAC daim ntawv thov pib nrog nruam nruam ntawm 6-8 hli tuab daim ntawv, ua raws los ntawm ntau- theem txias txo:

Txheej txheem Parameter:

Melting thiab Refining:

Kub: 720-750℃nrog argon degassing

Filtration: Ceramic foam filters (30–50 ppi) removing inclusions >20μm

Cov ntsiab lus hydrogen:<0.15 ml/100g Al to prevent porosity

Kub Rolling:

Txo los ntawm 6mm mus rau 2.5mm ntawm 350-400 degree

Kev tswj kom txias kom ua tiav cov qauv zoo ib yam (ASTM grain loj 5-7)

Txias Rolling Sequence:

Theem 1: 2.5mm → 1.2mm (intermediate anneal ntawm 350℃/ 4h)

Theem 2: 1.2mm → 0.3mm (intermediate anneal ntawm 340℃/ 5h)

Theem 3: 0.3mm → 0.09mm (qhov kawg thickness, H24 temper)

3.2 Thermal kho thiab annealing

Tom qab txias dov cov khoom yuav yog:

Tag nrho los yog ib nrab annealed (O temper)kom tau txais qhov siab tshaj plaws ductility rau kev sib sib zog nqus; los yog

Nyias tawv tawv (H-mob)thaum yuav tsum tau muaj zog ntxiv.

Annealing cycles (kub thiab lub sijhawm) tswj cov khoom siv kho tshuab thiab txo cov kev pheej hmoo ntawm ntug kev tawg thaum slitting thiab sib sau.

Ua rau Mechanical Properties hauv O Temper:

3.3 Slitting thiab ntug zoo tswj

Kev ua tiav kawg suav nrog precisionslittingmus rau qhov yuav tsum tau muaj dav, trimming ntawm burrs, thiab recoiling rau teev kauj ID / OD.

Ntug zoo yog qhov tseem ceeb rau cov khoom siv hluav taws xob - cov npoo ntxhib ua rau muaj teeb meem ntawm daim kab xev thiab ua rau muaj kev pheej hmoo ntawm seam to.

Zoo mills tshuaj xyuas ntug roughness thiab muab kev tiv thaiv ntim los tiv thaiv coil teeb cim thiab puas.

4. Qhov tseem ceeb ntawm 8011 Aluminium Foil 90μm rau Cov Tub Hluav Taws Xob

Qhov tshwj xeeb ntawm 90μm 8011-H24 txhuas ntawv ci muab cov txiaj ntsig kev ua tau zoo nyob thoob plaws ntau qhov haujlwm engineering:

Mechanical Durability:

Lub zog tensile 120-170 MPa muab 60% ntau dua rau kev tsim kua muag thaum lub sijhawm teeb tsa piv rau 50μm lwm txoj kev, qhov tseem ceeb thaum rub cov ducts hloov tau los ntawm cov kab noj hniav hauv qab nthab nrog kev pheej hmoo puas tsuaj.

Puncture kuj ntawm 40-60N ( ntsuas los ntawm ASTM D5748 kheej kheej sojntsuam) tiv thaiv kev puas tsuaj los ntawm kev sib cuag nrog kev tsim kho fasteners.

Barrier Performance:

Nrog dej vapor kis tus nqi (WVTR)<0.1 g/m²·day and oxygen transmission rate (OTR) <0.01 cm³/m²·day, the 90μm specification maintains insulation dryness even in high-humidity climates (85% RH, 30°C), preserving thermal conductivity of fiberglass insulation at rated 0.035 W/m·K rather than degraded 0.055 W/m·K from moisture absorption.

Thermal Efficiency:

High reflectivity (>85% ntawm infrared wavelengths) txo cov hluav taws kub kub nce hauv cov kav dej txias los ntawm 15-20% piv rau cov tsis muaj insulated lossis kraft- ntsib lwm txoj hauv kev, ua rau tag nrho HVAC lub zog txuag lub hom phiaj.

Lub thermal conductivity ntawm 210-220 W / (m·K) ua kom yooj yim rau qhov kub thiab txias sib npaug, tiv thaiv thermal lag hauv qhov sib txawv ntawm huab cua ntim (VAV).

Corrosion Resistance:

Lub Al-Fe-Si matrix muab kev tiv thaiv los ntawm atmospheric corrosion (qhov hnyav poob<0.1 mg/cm² in 1,000-hour salt spray testing per ASTM B117), with optional chromate-free conversion coatings or hydrophilic lacquers extending service life in coastal or industrial atmospheres .

Fabrication Compatibility:

3-5% elongation yam ntxwv ua rau muab kauv tsim rau hauv cov kav dej hloov tau nrog 50-1,000mm diameters yam tsis muaj ntug tawg, thaum tswj kom muaj zog txaus rau tus kheej - txhawb nqa spans ntawm 1.2-1.5m hauv cov ntawv thov ductboard nruj.

Economic Optimization:

Ntawm 2.71 g / cm³ ceev, 90μm ntawv nyiaj ntxiv tsuas yog 0.244 kg / m² rau qhov hnyav, txo cov qauv kev txhawb nqa los ntawm 30-40% piv rau galvanized steel (7.85 g / cm³) thaum muab qhov sib npaug vapor barrier kev ua tau zoo.

5. Kev siv ntawm 8011 Aluminium Foil 90 Microns nyob rau hauv Cua Duct Systems

5.1 Commercial Building HVAC Systems

Hauv cov tsev lag luam, qhov twg HVAC systems suav txog 40-60% ntawm tag nrho cov kev siv hluav taws xob, 90μm 8011 ntawv ci ua haujlwm rau sab nrauv vapor barrier hauv AL-PET-AL laminated saj zawg zog ducts.

Cov kev qhia tshwj xeeb ua tau raws li ASHRAE 90.1 lub zog tus qauv kev cai rau cov dej xau (Class 6,<3 L/s·m² at 250 Pa) through superior seam integrity.

Hom Configuration:

FAQs

1. Puas yog 90mic aluminium foil tseem suav tias yog "hloov"?
Yog lawm. Txawm tias ntawm 0.09mm, 8011 alloy nyob rau hauv nws 'O' temper yog tsis tshua muaj muag thiab ductile. Nws tuaj yeem khoov tau yooj yim thiab tsim rau hauv cov duab helical ntawm cov kav dej hloov tau yooj yim.

Thaum nws yog me ntsis nruj dua li 20mic ntawv ci, nws qhov yooj yim dua yog qhov tsim nyog rau nws lub hom phiaj.

2. Puas yog 90mic foil ua rau cov kav dej ntsiag to?
Indirectly, yog. Qhov ntau dua rigidity ntawm 90mic ntawv ci pab cov kav dej tuav nws cov ntaub ntawv puag ncig txawm tias nyob rau hauv nruj khoov, uas txhawb nqa airflow smoother (tsawg turbulence).

Qhov no tuaj yeem ua rau txo qis hauv huab cua nrov (soosing suab) piv rau cov kav dej nyias nyias uas yuav vau lossis kink.

3. Puas yog cov ntawv ci no siv rau ob qho tib si sab hauv thiab sab nrauv ntawm cov kab hluav taws xob insulated?
Yog lawm. Nws yog qhov kev xaiv zoo tshaj plaws rau ob qho tib si. Raws li lub hauv paus ntsiab lus, nws muab ib tug ruaj, airtight channel rau huab cua.

Raws li lub tsho sab nrauv (vapor barrier) dhau ntawm cov rwb thaiv tsev, nws qhov siab puncture kuj yog qhov zoo dua qub, tiv thaiv cov txheej txheem rwb thaiv tsev me me los ntawm kev puas tsuaj thaum lub sijhawm teeb tsa.
