8079 O-Temper 0.008mm Aluminium Ntawv Nyiaj rau Ntim Khoom Noj

1. Lub hauv paus rau phau ntawv

8079 aluminium ntawv ci yog ib qho kev ua haujlwm siab alloy foil tsim tshwj xeeb rau kev ntim khoom noj. belongs rau 8xxx series ntawm txhuas alloys (Al-Fe-Si system), no series yog dav lees paub rau nws cov kev ua tau zoo heev thiab kev nyab xeeb khoom noj. Nrog kev hloov pauv tas mus li ntawm kev ntim khoom noj niaj hnub xav tau - ua raws li kev ua haujlwm me me, lub teeb yuag, eco-phooj ywg, thiab ncua lub neej txee-ultra-nyias aluminium ntawv ci tau dhau los ua cov khoom siv tsis tseem ceeb hauv kev lag luam ntim khoom lag luam.. Nws tshwj xeeb barrier zog, yooj, thiab zaub mov-qib kev nyab xeeb ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv cov khoom noj los ntawm lwm yam xws li ya raws, oxygen, teeb, thiab tsw uas tuaj yeem degrade zoo.

2. Dab tsi yog 8079 O-Temper 0.008mm Food Packaging Foil?

2.1 8079 Aluminium Alloy

8079 yog lub tshav kub-kho tau aluminium alloy teej tug mus rau 8xxx series. Nws siv aluminium (Al) raws li lub hauv paus hlau, nrog tswj ntxiv ntawm hlau (Fe), silicon (Thiab), tus kws dai txiv manganese (Mn), thiab lwm yam kab kawm. Qhov no alloy yog tsim tshwj xeeb rau kev tsim cov ntawv nyias nyias, nrog rau kev tsom mus rau kev txhim kho kev ua tau zoo thiab qhov zoo ntawm qhov chaw-qhov tseem ceeb hauv cov ntawv ntim khoom noj uas qhov sib xws thiab kev nyab xeeb yog qhov tseem ceeb.

Cov yam ntxwv tseem ceeb ntawm 8079 aluminium alloy muaj xws li ductility zoo heev, zoo corrosion kuj, thiab ruaj khov mechanical zog tom qab annealing. Tsis zoo li lub zog muaj zog aluminium alloys, 8079 prioritizes formability thiab yooj, ua rau nws haum rau txias dov rau hauv ultra-thin foils (raws li nyias li 0.006mm) tsis muaj cracking lossis defects. Nws cov tshuaj muaj pes tsawg leeg yog nruj me ntsis tswj kom tau raws li cov qauv zaub mov, xyuas kom tsis txhob muaj teeb meem tshuaj lom thaum sib cuag zaub mov.

2.2 Temper Designation: O-Temper

Cov “O” hauv “8079 O-Tauj” sawv rau “Ib qho tseem ceeb (Mos)”. Qhov kev kub ntxhov no qhia tau hais tias cov ntawv txhuas txhuas tau dhau los ua tiav cov txheej txheem kev kho cua sov. Cov txheej txheem no softens cov khoom mus rau nws lub zog qis tshaj plaws thiab siab tshaj plaws ductility xeev. Rau ntim khoom noj, O-temper yog qhov tseem ceeb vim nws muab qhov tsim nyog softness thiab formability rau txoj folding, kev sau, thiab sealing kev ua haujlwm yam tsis muaj kev pheej hmoo ntawm cov ntawv ci tawg lossis tawg.

2.3 Cov yam ntxwv ntawm 0.008mm Thickness

Thickness ntawm 0.008mm (8 microns) distinguishes no ntawv ci los ntawm thicker zaub mov foils (E.G., 0.01mm los yog 0.012mm). Nws cov qauv ultra-thin muaj ntau yam zoo:

• Ultra-Thin Structure:Qhov ntsuas nyias ua kom lub ntim ntim, txo qhov ntim tag nrho ntawm cov khoom kawg thiab txuag chaw cia thiab kev thauj mus los. Nws yog tshwj xeeb tshaj yog haum rau me me-hom ntim, xws li ib lub hnab ntim khoom noj txom ncauj lossis mini chocolate wrappers.
• Lub teeb & Nqi-Zoo:Piv rau cov ntawv tuab tuab, 0.008mm foil siv tsawg aluminium rau ib cheeb tsam, txo cov nqi raw khoom. Nws qhov hnyav hnyav kuj txo tus nqi tsheb thauj mus los, ua rau nws xaiv kev lag luam ntau dua rau cov khoom ntim khoom loj loj.
• Zoo heev Barrier Properties:Txawm tias nws thinness, 0.008mm 8079 aluminium ntawv ci tswj qhov tshwj xeeb barrier kev ua tau zoo tiv thaiv ya raws, oxygen, teeb, thiab tsw. Qhov no yog ntaus nqi rau qhov inherent ntom ntawm aluminium, uas yog impermeable rau feem ntau gases thiab kua, xyuas kom cov zaub mov tseem tshiab thiab flavorful rau ncua sij hawm.

3. Tshuaj lom neeg muaj pes tsawg leeg ntawm 8079 Aluminium Ntawv Nyiaj

Cov ntsiab lus alloying hauv 8079 ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm foil. Hlau thiab silicon yog qhov tseem ceeb tshaj plaws, txhim kho processability thaum txias dov thiab annealing. Hlau pab txhim kho cov qauv nplej, txo qhov kev pheej hmoo ntawm pinholes thiab deg tsis xws luag, thaum silicon txhim kho lub zog tsis muaj kev cuam tshuam yooj. Manganese pab txhawb rau corrosion kuj, kom ruaj ntseg thaum cov ntawv ci tiv tauj cov khoom noj acidic lossis moist. Kev tswj nruj ntawm impurities xws li tooj liab thiab magnesium yog qhov tseem ceeb rau kev ua kom tau raws li cov qauv zaub mov, raws li cov qib ntau dhau tuaj yeem nkag mus rau hauv cov zaub mov lossis ua rau tsis muaj xim.

4. Cov khoom ntawm 8079 O-Temper 0.008mm Aluminium Ntawv Nyiaj

Barrier kev ua tau zoo yog ib qho ntawm cov khoom tseem ceeb tshaj plaws ntawm cov ntawv ntim khoom noj, cuam ​​tshuam ncaj qha rau lub txee lub neej thiab kev ntim khoom zoo. 8079 O-temper 0.008mm ntawv ci muaj qhov tshwj xeeb tiv thaiv plaub yam tseem ceeb uas ua rau cov zaub mov tsis zoo:

4.1 Moisture Resistance

Aluminium ntawv ci yog inherently impermeable rau dej vapor, tiv thaiv ya raws ingress uas tuaj yeem ua rau sogginess, pwm, los yog lwj. Lub 0.008mm thickness tswj no impermeability, ua kom haum rau cov khoom noj qhuav xws li khoom noj txom ncauj, dej kas fe, thiab tshuaj yej.

4.2 Oxygen Barrier

Oxygen yog thawj qhov ua rau cov zaub mov oxidation, ua rau rancidity, kev hloov xim, thiab tsw poob. 8079 foil muab cov pa oxygen barrier zoo heev, txo cov pa oxygen kis mus rau zero, yog li ncua lub txee lub neej ntawm oxidation-sensitive zaub mov zoo li chocolate, txiv ntseej, thiab cov khoom siv mis nyuj.

4.3 Kev Tiv Thaiv Lub Teeb

Ultraviolet (UV) Lub teeb tuaj yeem degrade cov as-ham (E.G., Cov vitamins) thiab ua rau muaj xim hloov hauv cov zaub mov. Qhov opaque xwm ntawm aluminium ntawv ci thaiv txhua lub teeb, tiv thaiv cov zaub mov los ntawm cov duab-degradation thiab khaws cia nws cov khoom noj muaj txiaj ntsig thiab zoo li.

4.4 Aroma ceev

Lub impermeable qauv ntawm 8079 ntawv ci tiv thaiv qhov poob ntawm volatile aromatic compounds los ntawm cov khoom noj, kom ntseeg tau tias cov khoom khaws lawv qhov xav tau tsw thiab tsw. Nws kuj tiv thaiv cov ntxhiab tsw sab nraud los ntawm kev nkag mus rau hauv pob, tuav lub saj ntshiab.

5. Manufacturing txheej txheem ntawm 8079 Khoom noj khoom haus Ntim Ntawv

Kev tsim khoom ntawm 8079 cov ntawv ntim zaub mov pib nrog kev xaiv raw khoom nruj heev, siv high-purity aluminium ingots (≥99.7% Al) raws li lub hauv paus, nrog precisely proportioned Fe, Thiab, Mn, thiab lwm yam alloying ntsiab kom ua tau raws li cov qauv zaub mov qib thiab kev ua tau zoo. Tom qab kuaj xyuas, cov khoom nkag mus rau hauv cov txheej txheem dov.

5.1 Casting thiab Kub Rolling

Aluminium ingots yog thawj rhuab nyob rau hauv ib tug homogenizing rauv ntawm 500 ° C - 550 ° C., ces kub dov rau hauv daim hlau 6-10mm tuab.

5.2 Txias Dov Thiab Annealing

Cov phiaj no yog tom qab txias-kub ntawm chav tsev kub kom txo cov thickness rau 0.1-0.2 hli. Ib qho kev kho annealing tag nrho ua raws li (300° C-400 ° C rau 2-4 teev) kom tshem tawm cov kev ntxhov siab sab hauv thiab ua kom cov khoom muag muag, ua tiav O-temper zog.

5.3 Precision Foil Rolling thiab Finishing

Cov nplooj ntawv annealed undergo precision foil dov, nrog ntau dhau los txo cov thickness rau 0.008mm. Thoob plaws qhov txheej txheem no, dov zeb nro, hov ceev, thiab cov khoom noj-qib lubricants yog nruj me ntsis tswj kom muaj ib tug du nto thiab uniform thickness. Kawg no, cov ntawv ci yog ntxuav nrog zaub mov-qib cov kuab tshuaj, qhuav kom tshem tawm cov seem impurities, thiab raug mus rau automated thiab phau ntawv tshuaj ntsuam xyuas rau cov khoom nrog uniform thickness, tsis muaj pinholes, thiab tsis muaj qhov tsis xws luag, kom ntseeg tau tias ua tau raws li cov kev cai ntim khoom noj zoo.
