Kumvetsetsa Miyezo ya Aluminium Foil "Pinhole" Pakuyika Chakudya ndi Chifukwa Chake Mapini Ochepa Amatsimikizira Chitetezo Chapamwamba

Aluminium zojambulazo ndi chimodzi mwa zinthu zofunika kwambiri chotchinga mu phukusi lamakono chakudya. Zake kwapadera kukana chinyezi, mpweya, kutumiza kununkhira, komanso kuwala kumapangitsa kukhala kofunikira kwambiri pamakapisozi a khofi, matumba osinthasintha, kunyamula mkaka, kubweza matumba, ndi zojambulazo za matuza. Komabe, ntchito ya zojambulazo za aluminiyamu zimadalira kwambiri chizindikiro chimodzi chofunika kwambiri: chiwerengero cha pinhole.

The Aluminiyamu zojambulazo pinhole muyezo imakhala ndi gawo lalikulu pakuwunika ngati chojambulacho ndi choyenera kukhudzana mwachindunji ndi chakudya komanso kusungidwa kwanthawi yayitali. Ngakhale zibowo zazing'ono kwambiri - zomwe nthawi zambiri siziwoneka ndi maso - zimatha kufooketsa chotchinga choteteza., kufulumizitsa makutidwe ndi okosijeni a chakudya ndikuchepetsa moyo wa alumali wazinthu. Nkhaniyi ikufotokoza zisonyezo zazikulu zomwe zimagwiritsidwa ntchito padziko lonse lapansi kuyesa mapini muzojambula za aluminiyamu ndikumveketsa bwino chifukwa chake kutsika kwa pinhole ndikofunikira pakuyika kotetezeka komanso kodalirika..

Zizindikiro zazikulu za Aluminium Foil Pinhole Standard

Makampani opanga zinthu padziko lonse lapansi (chakudya, mankhwala, ndi ukhondo) yenizani ma pinhole a aluminiyamu potengera ma metric angapo oyezeka. Zizindikiro zofunika kwambiri zikuphatikizapo:

1. Pinhole Count pa Square Meter

Ichi ndiye chizindikiro chachikulu pamiyezo yambiri yapadziko lonse lapansi.
Opanga amawerengera kuchuluka kwa mabowo mkati mwa dera linalake (mwachinthu 1 m²) pansi pa kuyatsa koyendetsedwa ndi kukulitsa.

Zizindikiro zodziwika bwino zamafakitale zikuphatikiza:

• ≤ 200 mapini/m² kwa 7-9 μm chojambula cha chakudya
• ≤ 50 mapini/m² kwa 10-12 μm premium chakudya ma CD zojambulazo
• ≤ 5 mapini/m² kwa zojambulazo za matuza (8011, 8021, 8079)

The woonda zojambulazo, m'pamenenso kumakhala kovuta kwambiri kuti tipewe mabowo, ndichifukwa chake zojambula zowonda kwambiri (6-7 mmi) amawunikidwa pogwiritsa ntchito mitundu yosiyanasiyana ya kulolerana.

2. Zokwanira Zovomerezeka za Pinhole Diameter

Chidule kukula ndi zofunika monga kuchuluka.
Mitundu yodziwika bwino imaphatikizapo:

• Ma pinhole ang'onoang'ono: < 0.1 mm
• Ziphuphu zazing'ono: 0.1-0.3 mm
• Ziphuphu zazikulu: > 0.3 mm (nthawi zambiri osavomerezeka kulongedza chakudya)

Miyezo yambiri yoyika zakudya imafunikira palibe zikhomo zazikulu kuposa 0.3 mm, chifukwa izi zikhoza kusokoneza kusindikiza umphumphu ngakhale pambuyo lamination.

3. Chilema Distribution Uniformity

Ngakhale chiwerengero chonse cha pinhole chili mkati mwachidziwitso, kusonkhanitsa kungapangitse madera ofooka. Choncho, Kufanana kumawunikidwa pogawa zojambulazo m'magulu angapo ndikuwunika kuchuluka kwa vuto la komweko.

Chofunikira chenicheni:

• Palibe m'modzi 100 cm² ayenera kupitirira 20-30% chiwerengero chonse chololedwa cha pinhole.

4. Mayeso Otumiza Kuwala

Dongosolo loyang'ana mwamphamvu kwambiri limagwiritsidwa ntchito pozindikira timiyendo tating'ono kwambiri (< 0.01 mm) kuti kuyendera pamanja sikungazindikire.

Owongolera ndi opanga apamwamba akudalira kwambiri machitidwe owonera okha, kumene zojambulazo zimafufuzidwa pa liwiro loposa 200 m / wanga.

5. Kugwirizana kwa Mafuta-Stain ndi Rolling-Defect Correlation

Zotsalira za mafuta, zokopa, fumbi particles, ndi zinyalala zachitsulo pakugubuduza zimatha kuyambitsa kapena kukulitsa mapini. Miyezo ina imalumikizana ndi kuipitsidwa ndi kachulukidwe ka pinhole konenedweratu.

Malire a kalasi ya kuipitsidwa akuphatikizapo:

• Kuchuluka kachulukidwe wamawanga ≤ 3 malo / m²
• No mosalekeza zikanda zakuya kuposa 2 μm

Kulumikizana kwamtunduwu kumatsimikizira kuti zoopsa za pinhole zimayendetsedwa pamizu.

Chifukwa Chake Zowonongeka Zochepa Za Pinhole Zimatsimikizira Chitetezo Chabwino Choyika Chakudya

1. Kuchita Bwino kwa Oxygen ndi Water Vapor Barrier Performance

Chojambula cha aluminiyamu sichingafanane ndi mphamvu yotchinga kokha pamene chiri chonse.
Phiri lililonse limapanga njira yolunjika ya mpweya ndi chinyezi, kuchepetsa kwambiri alumali moyo kwa:

• Mtedza
• Khofi
• Mkaka waufa
• Zokometsera
• Zakudya zophikidwa ndi vacuum
• Zokometsera zamadzimadzi

Kuchuluka kwa okosijeni wazakudya kumawonjezeka mwachangu ngakhale kutayikira kwapang'onopang'ono kumakhalapo.

2. Kusunga Kununkhira Kwabwinoko ndi Kukhazikika kwa Flavour

Zonunkhira, tiyi, ndipo khofi amakhudzidwa kwambiri ndi kutayika kwa fungo.
Pinhole-induced micro-permeation imatha kuyambitsa:

• Kuwonongeka kwa fungo
• Kuchuluka kwa mafuta ochulukirapo
• "Stale" kapena fungo losasangalatsa mu khofi ndi mbewu zokazinga

Ma pinholes ochepa = kusunga fungo lamphamvu.

3. Kupititsa patsogolo Kukaniza kwa Bacterial ndi Chemical Contamination

Ngakhale mabakiteriya sangathe kudutsa zojambulazo mosavuta, pinholes akhoza kulola:

• Zowonongeka zazing'ono zowulutsidwa ndi mpweya
• Nkhungu spores
• Nthunzi wamankhwala
• Package-line humidity ingress

Izi ndizofunikira makamaka pamalaminates ambiri omwe amagwiritsidwa ntchito popanga ma retort ndi aseptic.

4. Kulumikizana Kwabwinoko kwa Lamination ndi Mphamvu Zamapangidwe

Pamene pinholes alipo, zomatira malowedwe pa lamination amakhala wosagwirizana, kupanga madera omangika ofooka. Popita nthawi, Izi zitha kukhala:

• Kuzenga
• Mapangidwe a bubble
• Chojambula chosokonekera pansi pa kusindikiza kwa kutentha

Kuchulukitsa kotsika kumayambitsa kukhazikika kwa nthawi yayitali.

5. Mawonekedwe oyenera ndi mawonekedwe amtundu

Mapulogalamu a Premium amafunikira kuwunika komwe kumawonetsa mtundu. Kuchulukitsa kwambiri nthawi zambiri kumakhala kogwirizana ndi zolakwika zapamwamba monga:

• Mizere yozungulira
• Kukundani
• Ming'alu yaying'ono
• Kuwala kosagwirizana

Zochepa zochepa zimawulula bwino kukwera bwino ndikuponyera, Kulimbikitsanso mbiri ya wopanga.

Zida Zamakampani Zogwiritsidwa Ntchito Kuti Mupeze Mapini Ochepa

Njira zina zopangira ma alloys ndi zomangira zimakondedwa ngati milingo yotsika kwambiri ya pinhole ikufunika:

Kukonzekera koyenera, kufinya, ndi kugubuduza kwa masitepe ambiri ndikofunikira kuti mawonekedwe a zojambulazo azikhala okhazikika komanso kuchepetsa zolakwika.
