3. Cov Khoom Siv Hluav Taws Xob thiab Cov Khoom Noj Khoom Noj Qib Coated Aluminium Ntawv Nyiaj

Qhov tshwj xeeb ua tau zoo ntawm cov zaub mov qib coated aluminium ntawv ci yog qhov tshwm sim ntawm kev sib xyaw ua ke thiab kev sib cuam tshuam ntawm nws cov khoom tseem ceeb.

3.1 Aluminium Ntawv Nyiaj

Aluminium substrate tsim cov txheej txheem tseem ceeb thiab kev tiv thaiv kev tiv thaiv.

Feem ntau, aluminium ntawv ci siv hauvntim khoom nojranges nyob rau hauv thickness los ntawm6-50 micrometers (µm).

Common alloys, xws li1235i ib8011, raug xaiv rau lawv qhov zoo sib npaug ntawm malleability, lub zog, thiab purity.

Cov yam ntxwv tseem ceeb ntawm aluminium ntawv ci hauv cov ntsiab lus no suav nrog:

Impermeability:Nws muab qhov ze rau -txoj kev tsis sib haum xeeb rauoxygen, noo noo (dej vapor), lub teeb (UV thiab pom spectrum), thiab kab mob. Piv txwv li, Water Vapor Transmission Rate (WVTR) thiab Oxygen Transmission Rate (OTR) rau 9 µm txhuas ntawv nyiaj feem ntau ua tau zoo.0 g / m² / 24h thiab 0 cm³ / (m²·hnub)Feem ntau, ib qho kev ntsuas rau kev ua haujlwm tsis zoo.

Thermal conductivity:High thermal conductivity tso cai rau kom muaj cua sov los yog txias ntawm cov zaub mov ntim, tseem ceeb rau cov ntawv thov xws li ci los yog retort sterilization.

Formability & Tuag -Fold:Nws cov ductility tso cai rau nws zoo li lub thawv, lub hau, lossis cov ntaub qhwv zoo nkauj, tuav nws daim ntawv ib zaug.

Purity:Rau kev sib cuag zaub mov, cov txhuas yuav tsum tau ua raws li cov qauv purity nruj, feem ntau>99% ntshiab aluminium, los tiv thaiv cov leaching ntawm cov hlau hnyav lossis lwm yam khoom tsis zoo.

3.2 Cov txheej txheem zaub mov - hom thiab kev ua haujlwm

Coatings hloov cov hlau inert mus rau hauv ib qho kev sib txuas uas tuaj yeem raug kaw, luam tawm lossis sib koom ua ke. Cov tsev neeg coatings tseem ceeb yog:

Thaum tshav kub kub- seal lacquers (aqueous, hnyav, UV):qhuav qhuav heev -coat luj (kev lag luam raug≈ 4–8 g/m²) tuned rau qhov pib qhov kub thiab txias, kub-tack thiab tev tus cwj pwm. Lawv qhov zoo muaj xws li kev luam ntawv zoo heev thiab qis ntxiv loj; downsides muaj xws li cov neeg kho tshuab robustness qis dua ib tug tag nrho polymer zaj duab xis.

Extruded polyolefin txheej (PE / PP):thov los ntawm extrusion lamination muab cov thicker, mechanically robust sealants (hom sealant thickness≈ 15–30 µm). Lawv muaj qhov kub siab tshaj -tack thiab puas kuj thiab yog nyiam rau cov hnab, induction liners thiab retortable pob.

Primers thiab adhesion txhawb nqa:nyias txheej txheej uas txhim kho kev sib raug zoo ntawm cov hlau thiab polymer thiab txo qhov kev pheej hmoo delamination thaum tsim.

Barrier dispersions / tshwj xeeb txheej:Piv txwv li, PVdC lwm los yog PCTFE dispersions siv qhov chaw tiv thaiv tsw, tshuaj tiv thaiv los yog tsawg permeability yuav tsum tau.

Kev xaiv ntawm txheej txheej chemistry yog tsav los ntawm lub hom phiaj substrate rau foob (PP khob, PET tais, PE hnab), qhov yuav tsum tau tev profile (yooj yim-peel vs ruaj ruaj), kub raug (retort, kub-sau), thiab kev cai txwv (tsawg-migration rau pharma).

4. Cov txheej txheem tsim khoom

4.1 Aluminium foil dov thiab annealing (zeb theem)

Cov kauj ruam tseem ceeb ntawm kev tsim khoom uas cuam tshuam rau hauv qab txheej txheej zoo:

Casting thiab kub dov- teeb tsa thawj ingot qauv.

Txias dov mus rau strip gauge- ntau dhau mus kom txog qhov tuab tuab; nto oxide thiab cov cim rau cov menyuam yog tsim nyob rau theem no.

Annealing cov kauj ruam- tswj temper thiab recrystallization kom ua tiav lub hom phiaj ductility thiab tuag -fold cov khoom.

Nto xov / tu- tshem tawm cov roj zeb thiab cov pa paug; nto tiav (ci vs npub) xaiv rau txheej lossis luam ntawv xav tau.

Cov yam ntxwv zoo yuav tsum tau los ntawm cov mills: thickness uniformity los yog daim ntawv qhia; pinhole suav; thiab kev ruaj ntseg ntawm kev kub ntxhov nyob rau hauv coils.

4.2 Txheej Daim Ntawv Thov Txheej Txheem

Kev xaiv txheej txheej yog nyob ntawm hom txheej txheej, nws cov viscosity, thiab qhov xav tau thickness thiab tiav.

Gravure Txheej:Siv cov engraved cov menyuam mus rau qhov tseeb, zoo ib yam ntawm cov kua txheej rau ntawm cov ntawv ci. Zoo tagnrho rau nyias, cov khaubncaws sab nraud povtseg thiab cov qauv txheej.

Reverse Roll Txheej:Ua haujlwm cov txheej txheem ntawm cov menyuam uas cov txheej txheej txheej rotates nyob rau hauv qhov kev taw qhia ntawm tus neeg thov cov menyuam, kom ntseeg tau tias zoo ib yam, nyias txheej, tshwj xeeb tshaj yog thoob plaws webs.

Flexographic txheej:Siv lub phaj nyem hloov pauv hloov cov txheej txheem, feem ntau siv rau kev luam ntawv tab sis kuj siv rau cov txheej txheem ua haujlwm, muab ntau yam.

Extrusion txheej:Rau cov khaubncaws sab nraud povtseg tuab (piv txwv li, PE), molten polymer yog extruded los ntawm ib lub qhov tuag ncaj qha mus rau qhov txav aluminium ntawv ci web, tsim ib txheej txuas ntxiv. Txoj kev no muaj txiaj ntsig zoo rau kev tsim cov cua sov- foob txheej.

Tom qab txheej txheej, cov ntawv ci dhau los ntawm kev ziab lossis kho qhov cub kom ua kom cov txheej txheej, evaporate cov kuab tshuaj (yog cov kuab tshuaj-raws li), thiab hla - txuas polymers.

Cov kauj ruam no yog qhov tseem ceeb rau kev ua kom muaj kev ruaj ntseg ntawm txheej txheej, adhesion, thiab ua tiav cov khoom noj khoom haus tag nrho los ntawm kev tshem tawm cov tshuaj tsis haum tshuaj organic (VOCs).

4.3 Slitting thiab rerolling

Tom qab txheej thiab curing, master rolls yog slit rau converter widths. Lub tswv yim zoo slitting tiv thaiv ntug kev puas tsuaj uas tuaj yeem ua rau lub vev xaib tawg lossis ntug - pib delamination.

Khaws thiab thauj cov coated yob nyob rau hauv qhuav, plua plav-dawb tej yam kev mob nrog tiv thaiv npog - av noo thiab mechanical shocks ua rau tsis xws luag.

4.4 Hauv - txheej txheem Kev Tswj Xyuas Zoo

Kev tswj hwm nruj nruj yog kos thoob plaws hauv cov saw hlau tsim khoom:

Txheej Nyhav / Thickness:Ntsuas tsis tu ncua online siv cov sensors (piv txwv li, beta gauges) thiab offline los ntawm kev ntsuas gravimetric.

Kev Ntsuas Adhesion:Standardized xeem (piv txwv li, daim kab xev xeem, tev xeem) xyuas cov kev sib raug zoo zog ntawm cov txheej thiab txhuas.

Kev tshuaj xyuas qhov muag:Automated optical soj ntsuam tshuab kuaj xyuas qhov tsis xws luag, pinholes (tus pinhole suav ntawm<10 pinholes/m²yog ib qho kev thov rau kev thov ntawm 9µm), thiab txheej txheej tsis sib xws.

Kev Xeem Sealability:Rau cov cua sov-cov ntaub ntawv pov thawj coated, cov qauv raug kaw thiab kuaj xyuas lub zog foob (piv txwv li,tev lub zog ntawm 5-15 N / 15mmnyob ntawm daim ntawv thov) thiab kub tack.

Kev kuaj kev tsiv teb tsaws chaw (Offline):Cov qauv yuav raug kuaj xyuas kev tsiv teb tsaws chaw siv cov khoom noj simulants kom ua raws li cov kev cai txwv.
