Gịnị bụ kpọmkwem ngwa ndapụta nke 3003 aluminom foil n'ọhịa nke nkwakọ nri?
1. Ndubata: Ntọala nke 3003 Aluminom Foil na nkwakọ ngwaahịa nri
3003 aluminom foil, Al-Mn alloy (1.0%-1.5% Mn, ≤0.7% Fe), bụ isi ihe ndabere na nkwakọ nri. Ọ na-anya isi ike n'ibu (140-160MPa oyi-akpọrepu ike tensile), ezigbo nguzogide (0.12-0.15mm / afọ na-anọpụ iche ọnụ ịgba nnu), ezi formability (10%-12% elongation), na nchekwa ọkwa nri (kwekọrọ na FDA 21 CFR §175.300 na GB 4806.8).
O doro anya, tụnyere 1060 foil na-adị ọcha, Oge nke abụọ nke Mn-induced Al₆Mn na-akwalite nguzogide corrosion (karịsịa megide nri acidic) na ike-n'ụzọ dị irè na-edozi mmebi okwu na elu okpomọkụ sterilization na miri ịbịaru Filiks.
Ozoro, megidere 5052 aluminom foil, 3003 aluminom foil akwụ ụgwọ 15%-20% Mpekarị, na-eme ka ọ dị mma maka mmepụta ihe buru ibu. Uru arụmọrụ a na-akwụ ụgwọ na-etinye ntọala siri ike maka ngwa ya zuru ebe niile na nkwakọ nri.
Crucially, mkpa bụ isi nke nkwakọ nri—gụnyere ihe mgbochi, iguzogide gburugburu ebe obibi, formability, na nchekwa — dabara na ya 3003 Aluminom foil ihe dị mkpa. Oge ugbua, ọ na-aza maka ihe dịka 35% nke aluminom foil eji na ngalaba nkwakọ nri (2024 akụkọ ụlọ ọrụ zuru ụwa ọnụ), na-ekpuchi ọnọdụ dị iche iche dị ka nri dị njikere iri, mkpụrụ ọhụrụ, na oyi na-atụ yinye lọjistik.
Iji gosi nke ọma na arụmọrụ dị iche n'etiti 3003 Aluminom foil na ndị ọzọ a na-ahụkarị aluminom na nkwakọ nri, a na-enye tebụl na-esonụ:

2. Isi Ngwa ndapụta nke 3003 Aluminom Foil na nkwakọ ngwaahịa nri
(1) Nkwakọ ọgwụ mgbochi oke ọkụ: Na-eguzogide 121-135 ℃
Mgbochi na-ekpo ọkụ dị oke mkpa maka ichekwa nri mkpọ na nri ndị a kwadebere, na-achọ ihe nkwakọ ngwaahịa na-adịgide adịgide na enweghị mmiri n'okpuru oke okpomọkụ. 3003 Aluminom foil karịrị na nke a dịruru ná njọ n'ihi na ya ≥200 ℃ nro okpomọkụ., ≥80% ogo njigide ike dị elu, na arụ ọrụ mkpuchi siri ike.
Ngwa bụ isi ebe a bụ nkwakọ ihe mejupụtara akpa retort:
- Ndoko: 3003 aluminom foil (0.03-0.05mm, H14 iwe) na-eje ozi dị ka ihe mgbochi oyi akwa, jikọtara ya na PET (elu oyi akwa, maka iguzogide ọkọ) na CPP (oyi akwa mkpuchi okpomọkụ n'ime) ime a “PET/3003 foil/CPP” ndoko;
- Uru: Oge Al₆Mn na-egbochi uto ọka na oke okpomọkụ. Post-sterilization, ike ikpo ọkụ na-adịgide ≥30N/15mm (maka GB/T 10004-2020), na nnyefe ikuku oxygen bụ ≤0.1cc/(m²·24hatm)- ịgbatị ndụ shelf nke nri ndị a kwadebere 12-18 otutu onwa;
- Ọmụmụ ihe ọmụmụ: Akara nri a kwadebere nke ọma na-eji oke 0.04mm 3003 nkwakọ ihe mejupụtara foil maka anụ ezi braised nke okpomọkụ. Mgbe 121 ℃ × 30min sterilization, ngwaahịa na-enweta ndụ nchekwa nke ọnwa 15 yana ọnụego mmebi nke <0.3%.
N'ofè retort obere akpa, arịa ndị na-eguzogide okpomọkụ bụ ngwa ọzọ bụ isi.
Tebụl na-esonụ na-achikota teknuzu paramita nke 3003 aluminom foil n'ime ọnọdụ nkwakọ ngwaahịa nri:

(2) Ngwakọta nri nri: Oke ikuku
Njuka (0-4℃) na oyi (-18℃ to -30 ℃) Ngwakọta nri nwere nsogbu nri pụrụ iche: Ihe dị ala na ntinye mmiri na akara site na nri nri. 3003 Aluminom foil na-ezute ihe ndị a na-eji ≥9% na -30 ℃ na ℃15n na-emegide ya (maka GB/T 31985-2015).
Maka nri oyi, kpụrụ ụdọ bụ nnukwu ngwa:
- Otu esi emeputa ihe: 3003 aluminom foil (0.05-0.07mm, H112 temp) na-adọta miri emi, ya na textures miri emi nke 1-2mm iji kwalite nkwado nhazi;
- Emume ngosi: Ọ na-egosi enweghị ebrittlement mgbe 3 ọnwa nke nchekwa na -25 ℃ na ọ dịghị cracks mgbe 10 cycles nke 180 ° ekwe, na nkwụsị nke 18-22N. Ntụkwasị obi a enyerela ya aka ijide ya 60% nke ahịa Pizza tray jụrụ oyi zuru ụwa ọnụ.
Maka ngwaahịa anụ jụrụ oyi kpọmkwem, A na-ahọrọ ngwugwu ihe mejupụtara:
- Ndoko: 3003 aluminom foil (0.025-0.03mm, Isi iwe) jikọtara ya na PA (n'ihi na puncture iguzogide) na PE (maka ikpo ọkụ) ime a “PA/3003 foil/PE” ndoko;

(3) Nkwakọ nri dị njikere-iri / ngwa ngwa: Dị fechaa & Kemgbamaokwu
Nri nri dị njikere iri nri na nkwakọ ngwaahịa ngwa ngwa chọrọ njirimara isi abụọ: dị fechaa imewe (iji belata ego) na mfe akpụ (maka ụdị dị iche iche). 3003 Aluminom foil kacha nta ọkpụrụkpụ nke 0.018mm na omimi ịbịaru ruru nke ≥1:3 mee ka ọ dabara nke ọma.
Akpa mgbochi nri dị njikere iri nri bụ ngwa a na-ahụkarị na igbe nri ngwa ngwa mkpofu bụ isi ngwaahịa ọzọ na udi a, dị ka nkọwa zuru ezu na tebụl n'elu.
(4) Nkwakọ nri pụrụ iche na-arụ ọrụ: Ngwọta ahaziri
Maka nri nwere ihe pụrụ iche chọrọ (E.G., ngwaahịa ụmụ ọhụrụ, ntụ ntụ ntụ), 3003 Enwere ike gbanwee foil aluminum site na usoro pụrụ iche iji gboo mkpa ezubere iche, dị ka ngwugwu aseptic maka nri mgbakwunye ụmụaka na nkwakọ ihe mgbochi dị elu maka nri ntụ ntụ.
3. Arụmọrụ Uru nke 3003 Aluminom foil
(1) Uru mejupụtara: Mn Element ike
Ihe nke Mn na 3003 Aluminom foil na-etolite usoro 0.5-1.0μm Al₆Mn, nke na-egbochi Cl na Ac⁻ mbuze (a na-ahụkarị na nri acidic nwere pH 3-5). Nke a na-ebelata ọnụ ọgụgụ corrosion ya site na 40%-50% atụlere yana 1060 foil, na-egbochi mmebi nkwakọ ngwaahịa nke ọma.
Ọzọ, Mn na-enyere ma ihe ngwọta siri ike na-ewusi ike na mgbasawanye ike - na-ejigide ductility ma na-abawanye ike site na 30%-40% ikwu na 1060 foil. Nhazi a na-eme ka ọ dị mma maka ọnọdụ okpomọkụ dị elu na nke miri emi.
