1. Dab tsi yog cov kev ua zaub mov tseem ceeb tswj hwm kev tswj hwm kev tswj hwm txhuas cov ntawv ci txhuas cov ntawv ntim khoom tawg?
Teb:Aluminium ntawv ci rau kev sib cuag cov zaub mov yuav tsum ua raws li:
FDA 21 CFR 175.300(Tebchaws Asmeskas): Kev Txwv Tsis Txhob Txhob Txhob Txhob Txhob Ua Rau<1mg/kg food
EU 10/2011(Teb chaws Europe): Poob cov kev txwv kev tsiv teb tsaws chaw (SML) ntawm 5mg al / kg zaub mov
4806.9-2016(Suav teb): xav tau<0.2mg Al/dm² migration in 4% acetic acid
JFSL 370(Nyiv): Ua haujlwm<30ppm aluminum extraction in water at 60°C
Cov ntawv pov thawj xws li NSF / ANSI 51 thiab LFGB npog ntxiv cov kev txwv hlau hnyav (PB<0.01ppm, Cd<0.005ppm).
2. Yuav ua li cas txhuas cov ntawv ci kom tsis txhob noj zaubmov tsis zoo?
Teb:Ntawv ci muab peb npaug kev tiv thaiv:
Cov Khoom Siv Teeb Meem:
Cov pa pa roj oxygen (OTR):<0.005 cm³/m²/day
Dej Vapor Xa Tus Nqi (WVTR):<0.1 g/m²/day
Antimicrobial nto:
Ntuj Oxide Txheej Chiv Cov kab mob kev loj hlob (99. 9% txo hauv E. coli)
Kev tiv thaiv lub cev:
Puncture resistance >3n / μm tuab
Tsis muaj fiber ntau tsis zoo li ntawv ntim
3. Qhov kev xav txog kev nyab xeeb thaum siv ntawv ci nrog cov khoom noj acidic?
Teb:Acidic cov zaub mov (ph<4.5) require special precautions:
Kev twv: 3x Ntau dua Aluminium Midutation nyob rau hauv lws suav sauce (pH 3.5) vs dej
Cov kev daws teeb meem:
Siv lacquered ntawv ci (epoxy lossis polyamide txheej)
Saib xyuas kub<25°C
Txwv lub sijhawm sib cuag rau<24 hours for citrus/tomato products
Kev kuaj: ISO 4531 Qhia meej 4% acetic acid immersion ntawm 100℃rau 2h li kev sim ua phem tshaj plaws
4. Yuav ua li cas siv rov ua txhuas cov ntawv pov thawj ua cov khoom noj-qib.
Teb:Cov txheej txheem ua dua tshiab yuav tsum tau raws li:
Cov Khoom Siv Purity:
Eddy tam sim no sib cais ua tiav 99.9% Al Purity
XRF scanning tshem tawm cov khoom tsis huv
Kev rhuav tshem:
Thermal degassing ntawm 600℃tshem tawm cov organic cov issidues
Ntsev Slag kev kho kom tshem tawm cov oxides
Daim ntawv muaj cai:
EFSA yuav tsum tau muaj tag nrho cov khoom siv traceability
Thib Ib-Party Apit Per EN 16984 Cov Qauv
5. Yuav ua li cas tawm thev naus laus zis txhim kho kev nyab xeeb khoom noj?
Teb:Kev nruam muaj xws li:
Nano-tsho: Sio₂ txheej txo qhov kev tsiv teb tsaws chaw los ntawm 60%
Cov ntsuas ntse:
Lub sij hawm-kub cov neeg ua haujlwm (TTIS) rau pigabables
O₂ Sensors luam tawm ncaj qha rau ntawm ntawv nyiaj
Cov Ntim Ntim:
Ag-Ion Embedded Ntawv Nyiaj Ntev Nqaij Txee Lub Neej los ntawm 5 hnub
Oxygen-Scavenging Ntawv Nyiaj (Fe-Raws) Rau Cov Tshuab Kas Fes
Thaiv kev taug qab: Cov Khoom Siv Hluav Taws Xob Pob Zeb Los Ntawm Smelter Rau Tsev Loj
