Qhov tseeb txawv ntawm Kev Lag Luam
Aluminium ntawv ci yog cov khoom lag luam thoob ntiaj teb nrog cov txheej nqaim ntawm cov hlau thiab tempers, yog li cov hlau nws tus kheej hloov me ntsis ntawm ib cheeb tsam mus rau lwm qhov. Dab tsi txawv yog cov khoom architecture tsim nyob ib ncig ntawm nws. Plaub qhov sib txawv rau feem ntau ntawm cov kev sib txawv ntawm cov tsev neeg thiab cov khoom noj khoom haus: yob dav thiab hom, ntsuas, nto tiav, thiab daim ntawv pov thawj thiab daim ntawv lo thov tus neeg yuav khoom xav tau.
Yob dav thiab hom.Western European thiab North American khw muag khoom lag luam yog dominated los ntawm cov tsev neeg dav yob, feem ntau 300 hli thiab 450 hli, nkag rau hauv thawv nrog ib tug txiav ntug ua rau hauv lub ntim. Ntau lub khw hauv Esxias qhia txog kev sib koom ua ke ntawm nqaim nqaim thiab ua ntej- txiav cov ntawv, vim tias kev tswj xyuas feem thiab kev ua kom sov lossis qhwv cov khoom noj rau ib tus neeg tau txais txiaj ntsig zoo dua li cov yob dav. Khoom noj khoom haus thiab zaub mov- cov kev pabcuam hauv txhua cheeb tsam nyiam qhov ntev - cov ntawv yob ntsuas hauv kaum metres thiab hnyav dua.
Ntsuas.Cov ntawv ci hauv tsev yog feem ntau 10 txog 18 micron. Hnyav- cov qhab nia khiav ntawm li 20 mus rau 25 micron thiab tau teev tseg qhov twg qhwv yuav tsum txhawb nqa nws qhov hnyav lossis tiv taus tuav. Semi- cov thawv ntim khoom ruaj khov thiab cov khoom ntim khoom yog tuab dua. Gauge tsav tensile tus cwj pwm, puncture kuj thiab tus nqi ntawm cov hlau ib square meter, thiab nws yog ib qho tseem ceeb tshaj plaws parameter qhia thaum muab piv cov quotes los ntawm txawv keeb kwm.
Nto tiav.Bright -kho cov ntawv ci nrog lub ntsej muag ci thiab matte yog lub neej ntawd. Embossed finishes txhim kho kev xav ntawm tes thiab txo qhov thaiv ntawm cov khaubncaws sab nraud povtseg nyob rau hauv lub dispenser. Xim thiab metallised- cov nyhuv tiav yog qhov zoo nkauj heev thiab feem ntau hauv kev ntim khoom plig thiab khoom qab zib.
Alloy, Temper thiab Mechanical Requirements
Foil alloys raug xaiv rau formability, nto zoo thiab tus nqi ntau dua rau lub zog. Cov lus hauv qab no qhia txog cov ntaub ntawv feem ntau ntsib hauv ntim thiab cov ntawv ci hauv tsev, nrog rau tus qauv xa khoom siv rau txhua tus.
| Yam khoom | Hom specification | Sau ntawv |
|---|---|---|
| Alloy tsev neeg | 1235, 8079, 8011, 1145 | Hlau thiab silicon ntxiv txhawb zog hauv 8011 thiab 8079 |
| Kub | O (annealed), H18, H22 | Mos temper rau wrapping, nyuaj temper rau lidding |
| Tus qauv xa khoom (US) | ASTM B 479 Cov khoom lag luam | Annealed aluminium thiab aluminium -alloy foil |
| Tus qauv xa khoom (EU) | TS EN 546 Series | Technical tej yam kev mob ntawm tus me nyuam, khoom, tolerances |
| Qhov system npe | TS EN 573-3 | Tshuaj muaj pes tsawg leeg ntawm wrought aluminium khoom |
| Hom ntsuas | 10 mus rau 25 micron tsev neeg, 30 micron thiab siab dua ntim thiab hau | Paub meej los ntawm daim ntawv thov, tsis yog los ntawm tus cwj pwm |
| Tensile zog, mos ntawv ci | Kwv yees li ntawm 60 txog 110 MPa nyob ntawm cov hlau thiab kub | Txheeb xyuas daim ntawv pov thawj zeb |
Cov neeg yuav khoom yuav tsum hais txog cov alloy, npau taws thiab ntsuas kom meej thiab xav tau daim ntawv pov thawj zeb los siv cov hlau alloy, cov tshuaj muaj pes tsawg leeg thiab cov khoom siv ntawm cov khoom xa tuaj.
Khoom noj khoom haus- Hu rau Kev Ua Raws Cai thiab Kev Sau Npe
Cov ntawv ci uas kov cov zaub mov yog khoom noj-cov khoom sib cuag thiab raug tswj raws li qhov no. Nyob rau hauv European Union lub moj khaum yuav tsum tau zaum nyob rau hauv Regulation (EC) Tsis muaj 1935/2004, nrog plastics-raws li txheej thiab laminates soj ntsuam raws li Regulation (EU) Tsis muaj 10/2011 thiab hlau thiab hlau cov khoom soj ntsuam tiv thaiv lub teb chaws thiab Council of Europe kev taw qhia txog hlau thiab alloys. Hauv Tebchaws Meskas, cov txheej txheem siv rau cov ntawv ci yog nyob rau hauv 21 CFR 175.300 rau resinous thiab polymeric coatings, nrog rau cov ntawv tiav yuav tsum tsim nyog rau nws txoj kev npaj siv. Hauv Suav teb cov zaub mov tswj hwm{11}} cov qauv kev nyab xeeb yog GB 4806.1 rau kev nyab xeeb dav dav thiab GB 4806.9 rau cov khoom siv hlau thiab cov khoom hauv kev sib cuag nrog zaub mov, nrog GB / T 3190 siv rau cov tshuaj muaj pes tsawg leeg ntawm wrought aluminium.
Labeling sib txawv ua raws li kev cai es tsis yog kab lis kev cai. Cov lus tshaj tawm txog kev rov ua dua tshiab, cov ntsiab lus rov ua dua tshiab, qhov cub- qhov ntsuas kub tsis zoo thiab lub freezer haum yog yuav tsum tau los yog txwv nyob ntawm kev ua lag luam, thiab cov lus thov xws li "microwave safe" lossis "qhov cub nyab xeeb rau qhov ntsuas kub" yuav tsum tau txais kev txhawb nqa los ntawm cov ntaub ntawv ntsuas rau cov laminate tiav, tsis yog rau lub hauv paus ntawv ci ib leeg.
Channel Structure thiab yuav ua li cas nws zoo li xav tau
Qhov kev thov rau ib hom ntawv taug qab qhov tseem ceeb ua noj thiab zaub mov- cov qauv muag khoom hauv txhua lub khw. Qhov twg qhov cub roasting yog cov txheej txheem tseem ceeb hauv tsev, dav hnyav - ntsuas rolls nrog kub siab kam rau ua. Qhov twg steaming, grilling los yog txoj kev - zaub mov kev pab cuam yog dav, nqaim rolls, daim ntawv interleaves thiab laminated ntawv ci kom ceev - pab wrapping yuav ib tug loj dua. Lub tsev kawm ntawv thiab catering ntim hauv tsev so, airlines thiab tsev kho mob tsav tsheb ntev -cov ntawv yob, cov ntim ntim thiab ib nrab- cov thawv ntim khoom nruj, thiab cov kab no feem ntau qhia cov ntaub ntawv ua raws cai thiab ntsuas ntsuas nruj dua li cov khw muag khoom.
Rau ib tus neeg muag khoom lossis tus neeg muag khoom, qhov kev cuam tshuam zoo yog tias ib tsev neeg SKU tsis tshua muaj kev hloov pauv hauv kev lag luam. Cov hlau specification tej zaum yuav zoo tib yam, tab sis yob dav, core txoj kab uas hla, dispenser carton, daim ntawv lo ntawv thiab ua raws li tag nrho cov yuav tsum tau muab txhais rau ib lub lag luam ua ntej cov khoom hais.
Cov lus nug nquag
Q:Puas yog tsev neeg aluminium foil tib yam khoom thoob ntiaj teb?
A: Cov alloys thiab tempers yog dav zoo ib yam, tab sis yob dav, ntsuas, core loj, ntim thiab daim ntawv thov cov ntaub ntawv txawv los ntawm kev ua lag luam, thiab cov variables txiav txim seb ib tug SKU yuav muag nyob rau hauv ob peb cheeb tsam.
Q:Dab tsi gauge yog standard tsev ntawv ci?
A: Feem ntau cov ntawv ci hauv tsev yog 10 mus rau 18 micron rau cov qauv qib thiab txog 20 txog 25 micron rau cov qib hnyav -cov dej num. Thawv thiab lidding Tshuag yog thicker dua.
Q:Tus txheej txheem twg npog aluminium foil rau ntim?
A: ASTM B479 npog annealed aluminium thiab aluminium-alloy foil rau ntim hauv Teb Chaws Asmeskas system, thaum EN 546 series txhais cov txheej txheem ntawm kev xa khoom thiab kev ua siab ntev hauv Tebchaws Europe.
Q:Tus neeg yuav khoom yuav tsum qhia dab tsi thaum muab cov ntawv ci?
A: Alloy designation, temper, gauge nrog kam rau ua, nto tiav, yob dav, core inch, splice zaus, zaub mov -hu rau txoj kev ua raws cai thiab lub zeb daim ntawv pov thawj yuav tsum tau rau cov khoom xa tuaj.
Q:Puas yog foil xav tau ntawv pov thawj tshwj xeeb los kov cov zaub mov?
A: Yog. Cov kab lus tiav yuav tsum ua raws li cov khoom noj uas siv tau-kev tiv tauj rau hauv cov khw muag khoom, xws li Kev Cai (EC) Tsis muaj 1935/2004 thiab Txoj Cai (EU) Tsis muaj 10/2011 hauv EU, 21 CFR 175.300 rau cov txheej hauv Teb Chaws Asmeskas, lossis GB 6.948.1 hauv Suav teb.
Q:Cov ntawv ci tuaj yeem siv tau tom qab siv zaub mov?
A: Cov ntawv ci huv, tsis muaj coated tuaj yeem rov ua dua tshiab thiab khaws cov khoom seem siab. Cov kab mob hnyav heev los yog cov ntawv laminated yog qhov nyuaj rau rov qab los, uas yog vim li cas kev sau zoo tseem ceeb dua li metallurgy.
