Lub tshuab lamination SINOMECH peb-hauv-ib uas tau tso tawm ntawm peb tus khub lub Hoobkas, ua ke nrog cov nplaum laminating tsis muaj kuab tshuaj los ntawm Kangda—tus tsim cov nplaum saum toj kawg nkaus hauv Suav teb—muab cov kev daws teeb meem lamination ntau yam thiab yoog tau. Nws txhawb nqa qhov chaw siab peb-txheej aluminium foil lamination nrog overhead unwinding, muaj txoj kev luv luv uas txo qhov kev pheej hmoo ntawm kev tawg ntawm aluminium foil. Tsis tas li ntawd, nws tswj cov ntawv tiaj tus-yas thiab yas-yas lamination. Thaum cov xaj rau cov qauv peb-txheej tsis txaus, lub tshuab tuaj yeem hloov mus rau ob-txheej lamination kom haum rau ntau yam kev xav tau ntau lawm. Lub tshuab laminating ntawv-yas peb-hauv-ib thib ob uas tsis muaj kuab tshuaj muaj kev sib txuas ntawv-yas, qhov rai strip thiab qhov rai positioning, nrog rau cov peev xwm lamination ntawv tuab.
Kev Qhia Txog Daim Ntawv Thov: Kev Lamination Peb-hauv-Ib Qhov Chaw Siab Aluminium-Yas
· Cov Qauv Lamination: 12μm PET / 7μm AL / 55μm PE
· Cov Nplaum Laminating: Kangda WD8262A/B Ob-Component Solvent-Free Laminating Adhesive
WD8262A/B, tsim los ntawm Shanghai Kangda, yog thawj lub tuam txhab ua cov nplaum ob yam khoom uas tsis muaj kuab lom uas siv rau kev lamination txhuas ntawv ci. Zoo rau cov ntawv PET/AL composites uas luam tawm tag nrho, nws siv Kangda New Materials' mature aluminium foil lamination technology los tsim cov qauv tsis muaj qhov tsis zoo nrog xoom qhov dawb tam sim ntawd tom qab lamination. Cov yeeb yaj kiab tiav lawm tiv taus kev retort sterilization ntawm 121°C rau 40 feeb. Txhawm rau kom ua raws li lub hom phiaj txo cov pa roj carbon hauv tebchaws thiab txo cov pa phem ib puag ncig, cov chaw tsim khoom ntim khoom loj thoob plaws Suav teb maj mam hloov cov khoom siv txhuas ntawv ci qhuav nrog cov kev xaiv lamination tsis muaj kuab lom.
Cov Ntsiab Lus Tswj Xyuas Kev Txawj Ntse rau PET + AL + PE Peb Txheej Lamination Txheej Txheem
PET+AL+PE yog ib hom khoom sib xyaw ua ke uas muaj kev thaiv siab. PET muab lub zog thiab kev luam tawm tau yooj yim; ntawv ci txhuas muab cov haujlwm tseem ceeb xws li thaiv lub teeb, tiv taus oxygen thiab rwb thaiv dej; txheej PE sab hauv ua rau kaw tau cua sov thiab kov ncaj qha nrog cov ntsiab lus. Cov qauv no siv dav hauv cov khoom noj, tshuaj txhua hnub thiab cov khoom ntim tshuaj. Cov txheej txheem lamination xav tau kev ua kom raug - kev tswj hwm cov ntsiab lus tsis raug yuav ua rau muaj qhov tsis zoo xws li delamination, npuas, wrinkles, ntawv ci txhuas tawg thiab kaw tsis zoo thaum kub. Hauv qab no yog cov lus qhia tseem ceeb ntawm kev tswj hwm cov txheej txheem:
1. Kev Kho Ua Ntej Rau Cov Khoom Siv: Lub Hauv Paus ntawm Kev Ua Kom Zoo ntawm Lamination
Kev ua haujlwm ntawm txhua lub substrates yuav tsum tau tswj hwm kom zoo.
• Cov yeeb yaj kiab PET xav tau kev kho mob corona kom ua tau raws li qhov yuav tsum tau ua ntawm qhov chaw. Cov hmoov av thiab hluav taws xob static ntawm qhov chaw yuav tsum tau tshem tawm kom tiv thaiv cov txheej nplaum tsis sib npaug thiab cov txheej sib cais.
• Cov ntawv ci txhuas yog nyias, mos, yooj yim oxidized thiab npog nrog cov roj seem dov. Yuav tsum tau ntxuav thiab tshem cov roj ua ntej, ua raws li kev ua kom corona ua haujlwm kom ua tiav qhov nro ntawm qhov chaw ntawm ≥38 mN / m. Cov ntawv ci txhuas uas muaj oxidation, pinholes lossis creases raug txwv tsis pub ua, vim tias qhov tsis zoo no yuav ua rau kev ua haujlwm ntawm kev thaiv tsis zoo.
• Cov yeeb yaj kiab PE sab hauv yuav tsum tau ziab kom qhuav tag nrog cov dej noo tswj kom qis dua 0.05% kom tsis txhob ua kom dawb thiab npuas tom qab lamination. Cov dej nag ntawm qhov chaw yuav tsum tau tshem tawm kom ntseeg tau tias muaj kev sib txuas ruaj khov.
2. Kev Tswj Xyuas Qhov Nruj Thaum Lub Sijhawm Tsim Khoom (Qhov Tseem Ceeb Tshaj Plaws)
Yuav tsum muaj ib txoj cai sib txawv ntawm qhov sib zog sib txawv rau txhua txheej:
• PET muaj qhov ruaj khov heev; qhov kev sib zog rub tawm yog teem rau ntawm 90–110 N nrog qhov ceev ceev ruaj khov, sib npaug kom tswj tau cov nplaim zaj duab xis tiaj tiaj kom tsis txhob muaj kev hloov pauv.
• Cov ntawv ci txhuas tsis yooj yim ncab thiab yooj yim ncab thaum muaj kev nruj. Yuav tsum muaj kev nruj qis, ruaj khov ntawm 40–70 N. Kev pib siv tshuab, kaw lub tshuab thiab kev hloov kho qhov ceev yuav tsum maj mam kom tsis txhob muaj kev tawg me me thiab kev hloov pauv tensile los ntawm lub zog rub tam sim ntawd.
• Cov yeeb yaj kiab PE mos yuav tsum muaj qhov chaw nruj qis kom tiv thaiv kev ntsws tom qab ncab, uas ua rau cov khoom tiav lawm warpage thiab sib cais ntawm cov txheej. Kev nruj ntawm winding siv cov qauv txo qis kom tsis txhob muaj cov kab nrib pleb hauv paus thiab cov khoom poob.
3. Kev Sib Tw Tseeb ntawm Cov Txheej Txheem thiab Lamination
Kev siv cov txheej txheem lamination qhuav yog qhov txheej txheem zoo tshaj plaws nrog cov nplaum polyurethane ob-component. Kev tswj hwm nruj ntawm qhov sib xyaw ntawm cov nplaum thiab viscosity ua kom muaj kev ua tau zoo heev.
• Qhov hnyav ntawm cov txheej pleev ib yam tseem nyob li ntawm 3–5 g/m². Yog tias cov txheej pleev tsis txaus ces yuav ua rau cov nplaum tsis sib txuas zoo, tiam sis cov txheej pleev ntau dhau ua rau cov nplaum sib sau ua ke, thaiv thiab muaj ntxhiab tsw phem.
• Kev txheej txheem lamination ruaj khov: Muab PET lo rau nrog ntawv ci txhuas ua ntej, kho rau 2-4 teev, tom qab ntawd laminate nrog PE. Kev lamination ntau txheej tib lub sijhawm yuav ua rau cov nplaum tsis sib xws.
• Qhov kub ntawm kev lamination raug tswj ntawm 60–80°C nrog rau qhov siab nruab nrab, sib npaug. Qhov kub qis ua rau cov nplaum tsis khov tag; qhov kub ntau dhau ua rau cov zaj duab xis hloov pauv thermal thiab ua rau cov ntawv ci txhuas tawg.
4. Cov Lus Qhia Tseem Ceeb Txog Kev Kho Thiab Kev Ua Tom Qab Ua tiav
Cov khoom laminated uas ua tiav lawm raug xa mus rau chav kho kom sov tas li ntawm 40–50°C rau 24–48 teev kom cov nplaum sib txuas thiab kho tau tag nrho. Qhov no ua rau lub zog ntawm cov khaubncaws sab nraud povtseg ntawm cov khaubncaws sab nraud povtseg zoo dua qub thiab tshem tawm cov kev pheej hmoo ntawm kev tawg mus ntev.
Kev txiav thiab ua lub hnab tsuas yog ua tom qab nws qhuav tag. Cov khoom ntse tawv yuav tsum tsis txhob kov cov ntawv ci txhuas kom tiv thaiv kev puas tsuaj rau lub qhov.
Cov khoom tiav lawm yuav tsum tau khaws cia rau hauv qhov chaw uas tsis muaj teeb, qhuav thiab tsis muaj qhov kub thiab txias heev kom tsis txhob muaj cov pa roj carbon dioxide oxidation thiab cov kua nplaum hydrolysis tsis ua haujlwm. Yuav tsum tshem tawm cov plua plav thoob plaws hauv lub hoobkas kom tiv thaiv cov plua plav nkag mus rau hauv cov khaubncaws sab nraud povtseg, uas ua rau muaj qhov tawg thiab npuas, kom ntseeg tau tias cov khoom tiav lawm ua tau raws li cov qauv kev ruaj khov ntawm kev thaiv thiab lamination.
