Cov Lus Qhia: Daim ntawv no txheeb xyuas qhov teeb meem dawb ntawm cov yeeb yaj kiab sib xyaw ntawm PET / VMCPP thiab PET / VMPET / PE thaum lawv sib xyaw, thiab qhia txog cov kev daws teeb meem sib xws.
Aluminium coated composite zaj duab xis yog cov khoom ntim muag muag nrog "txhuas luster" tsim los ntawm kev sib xyaw ua ke ntawm aluminium coated films (feem ntau VMPET / VMBOPP, VMCPP / VMPE, thiab lwm yam, ntawm cov VMPET thiab VMCPP feem ntau siv) nrog cov yas pob tshab.Nws yog siv rau ntim khoom noj, khoom noj khoom haus, tshuaj pleev ib ce, thiab lwm yam khoom.Vim nws zoo heev metallic luster, yooj yim, affordability, thiab kuj zoo barrier kev ua tau zoo, nws tau lug siv (zoo barrier zog dua yas composite films, pheej yig dua thiab lighter tshaj aluminium-yas composite films).Txawm li cas los xij, cov pob dawb feem ntau tshwm sim thaum lub sij hawm tsim cov aluminium plated composite films.Qhov no tshwj xeeb tshaj yog pom nyob rau hauv cov khoom siv ua yeeb yaj kiab nrog PET / VMCPP thiab PET / VMPET / PE cov qauv.
1, Qhov ua rau thiab kev daws teeb meem ntawm "dawb pob"
Kev piav qhia ntawm "qhov chaw dawb" tshwm sim: Muaj cov pob dawb pom tseeb ntawm qhov pom ntawm cov yeeb yaj kiab sib xyaw, uas tuaj yeem muab faib ua ntu zus thiab sib xws.Tshwj xeeb tshaj yog rau cov uas tsis yog cov ntawv sau ua yeeb yaj kiab thiab tag nrho phaj dawb number case los yog lub teeb xim ink composite films, nws yog qhov pom tseeb dua.
1.1 Tsis txaus nto nro ntawm aluminium plating sab ntawm aluminium txheej.
Feem ntau, kev ntsuam xyuas qhov nro yuav tsum tau nqa tawm ntawm corona nto ntawm zaj duab xis siv ua ntej sib xyaw, tab sis qee zaum qhov kev ntsuam xyuas ntawm cov txheej txheem aluminium yog tsis quav ntsej.Tshwj xeeb tshaj yog rau VMCPP cov yeeb yaj kiab, vim tias muaj peev xwm los nag lossis daus ntawm cov khoom siv me me hauv CPP puag zaj duab xis, aluminium plated nto ntawm VMCPP cov yeeb yaj kiab khaws cia rau ib lub sijhawm yog qhov tsis txaus.
1.2 Tsis zoo leveling ntawm nplaum
Cov kuab tshuaj raws li cov nplaum yuav tsum xaiv qhov kev ua haujlwm zoo tshaj plaws ntawm kev daws teeb meem raws li cov khoom siv los xyuas kom pom cov kua nplaum zoo.Thiab kev ntsuas viscosity yuav tsum tau muab coj los siv thaum lub sijhawm ua cov txheej txheem sib xyaw ua ke.Thaum cov viscosity nce ntau, cov kuab tshuaj yuav tsum tau ntxiv tam sim ntawd.Cov lag luam nrog cov xwm txheej tuaj yeem xaiv cov khoom siv tsis siv neeg lub twj tso kua nplaum kaw.Qhov ntsuas kub zoo tshaj plaws rau cov kua nplaum tsis muaj kuab lom yuav tsum raug xaiv raws li cov khoom siv phau ntawv.Tsis tas li ntawd, xav txog qhov teeb meem ntawm lub sijhawm ua kom tsis muaj kuab lom, tom qab lub sijhawm ntev, cov kua nplaum hauv cov menyuam ntsuas yuav tsum raug tso tawm raws sijhawm.
1.3 Cov txheej txheem tsis zoo
Rau cov qauv PET / VMCPP, vim lub thickness me me thiab yooj yim extensibility ntawm VMCPP zaj duab xis, lub lamination cov menyuam siab yuav tsum tsis txhob siab dhau thaum lamination, thiab winding nro yuav tsum tsis txhob siab dhau.Txawm li cas los xij, thaum tus qauv PET / VMCPP yog sib xyaw, vim qhov tseeb tias PET zaj duab xis yog cov yeeb yaj kiab nruj, nws raug nquahu kom nce lub laminating roller siab thiab winding nro kom tsim nyog thaum sib xyaw.
Cov txheej txheem sib xyaw ua ke yuav tsum tau tsim raws li qhov xwm txheej ntawm cov khoom siv sib xyaw thaum sib txawv aluminium txheej txheej txheem sib xyaw.
1.4 Cov khoom txawv teb chaws nkag mus rau hauv cov yeeb yaj kiab sib xyaw ua rau "dawb pob"
Cov khoom txawv teb chaws feem ntau suav nrog cov plua plav, roj hmab, lossis cov khib nyiab.Cov plua plav thiab cov khib nyiab feem ntau yog los ntawm kev cob qhia, thiab feem ntau yuav tshwm sim thaum lub rhiav kev huv si tsis zoo.Cov khoom siv roj hmab feem ntau yog los ntawm cov roj hmab discs, txheej chais, lossis cov hlua khi.Yog tias cov nroj tsuag sib xyaw tsis yog qhov chaw ua haujlwm tsis muaj plua plav, nws tseem yuav tsum tau sim ua kom huv thiab huv ntawm cov khoom sib xyaw ua haujlwm, nruab cov khoom siv tshem tawm plua plav lossis cov khoom siv lim dej (cov cuab yeej txheej, phau ntawv qhia cov menyuam, cov cuab yeej sib txuas thiab lwm yam khoom siv) rau kev tu.Tshwj xeeb tshaj yog cov menyuam txheej, scraper, flattening roller, thiab lwm yam yuav tsum tau ntxuav tsis tu ncua.
1.5 Cov av noo nyob rau hauv lub rhiav ntau lawm ua rau "dawb pob"
Tshwj xeeb tshaj yog thaum lub caij los nag, thaum lub rooj cob qhia cov av noo yog ≥ 80%, cov yeeb yaj kiab sib xyaw yog qhov ua rau "dawb pob" tshwm sim.Nruab ib lub ntsuas kub thiab av noo nyob rau hauv lub rhiav los sau cov kev hloov ntawm kub thiab av noo, thiab xam qhov tshwm sim ntawm cov pob dawb tshwm.Cov lag luam nrog cov xwm txheej tuaj yeem xav txog kev txhim kho cov khoom siv dehumidification.Rau cov txheej txheem ntau txheej nrog cov khoom thaiv zoo, nws yog qhov yuav tsum tau txiav txim siab ncua kev tsim khoom lossis tsim ib txheej txheej ntau lossis sib txuas sib txuas.Tsis tas li ntawd, thaum ua kom ntseeg tau qhov kev ua tau zoo ntawm cov nplaum, nws raug pom zoo kom txo qis tus neeg saib xyuas siv kom tsim nyog, feem ntau yog 5%.
1.6 Gluing nto
Thaum tsis pom qhov txawv txav tsis pom tseeb thiab qhov teeb meem ntawm "dawb pob" tsis tuaj yeem daws tau, cov txheej txheem txheej txheej ntawm aluminium txheej sab tuaj yeem txiav txim siab.Tab sis cov txheej txheem no muaj kev txwv tseem ceeb.Tshwj xeeb tshaj yog thaum VMCPP los yog VMPET txhuas txheej yog raug tshav kub thiab nro nyob rau hauv qhov cub, nws yog nquag mus tensile deformation, thiab cov txheej txheem sib xyaw yuav tsum tau kho.Tsis tas li ntawd, lub tev lub zog ntawm aluminium plating txheej yuav txo qis.
1.7 Kev piav qhia tshwj xeeb rau qhov xwm txheej uas tsis muaj qhov txawv txav tau pom tom qab kaw, tab sis "dawb pob" tshwm sim tom qab kev loj hlob:
Hom teeb meem no yog nquag tshwm sim nyob rau hauv cov khoom sib xyaw ua ke nrog cov khoom thaiv zoo.Rau PET / VMCPP thiab PET / VMPET / PE cov qauv, yog tias cov qauv membrane yog tuab, lossis thaum siv KBOPP lossis KPET films, nws yooj yim los tsim "dawb pob" tom qab kev laus.
High barrier composite films ntawm lwm cov qauv kuj ua rau tib yam teeb meem.Piv txwv suav nrog siv cov ntawv txhuas tuab lossis cov yeeb yaj kiab nyias xws li KNY.
Lub ntsiab yog vim li cas rau qhov "dawb qhov chaw" tshwm sim yog hais tias muaj roj to hauv lub composite daim nyias nyias.Cov pa roj no tuaj yeem yog cov dej ntws ntawm cov kuab tshuaj seem lossis cov pa roj carbon dioxide ntau dhau los ntawm cov tshuaj tiv thaiv ntawm cov tshuaj tua kab mob thiab dej vapor.Tom qab cov roj ntau dhau lawm, vim tias cov khoom thaiv zoo ntawm cov yeeb yaj kiab sib xyaw, nws tsis tuaj yeem tso tawm, ua rau pom "dawb pob" ( npuas) hauv cov txheej txheem sib xyaw.
Kev daws: Thaum compounding hnyav raws li nplaum, cov txheej txheem tsis xws li qhov cub kub, huab cua ntim, thiab lub siab tsis zoo yuav tsum tau teeb tsa kom zoo kom ntseeg tau tias tsis muaj cov kuab lom nyob hauv cov nplaum nplaum.Tswj cov av noo nyob rau hauv lub rhiav thiab xaiv ib tug kaw nplaum txheej system.Xav txog kev siv cov tshuaj tua kab mob uas tsis tsim cov npuas.Tsis tas li ntawd, thaum siv cov kuab tshuaj raws li cov nplaum nplaum, nws yog ib qho tsim nyog los ntsuas cov dej noo hauv cov kuab tshuaj, nrog rau qhov yuav tsum tau muaj cov ntsiab lus noo noo ≤ 0.03%.
Cov saum toj no yog cov lus qhia txog qhov tshwm sim ntawm "dawb pob" hauv cov yeeb yaj kiab sib xyaw, tab sis muaj ntau yam laj thawj uas tuaj yeem ua rau muaj teeb meem zoo li no hauv kev tsim khoom tiag tiag, thiab nws yuav tsum tau txiav txim siab thiab txhim kho raws li qhov tseeb ntawm cov khoom tsim tawm.
