Metalized thermal lamination zaj duab xisyog ib qho kev sib xyaw ua ke ntawm cov khoom ntim khoom tsim los ntawm kev siv cov txheej txheem tshwj xeeb los pleev xim rau saum npoo ntawm cov yas zaj duab xis nrog ib txheej nyias nyias ntawm cov hlau txhuas, uas feem ntau siv cov txheej txheem yog lub tshuab nqus tsev aluminium plating, uas yog, cov hlau aluminium melts. thiab evaporates ntawm qhov kub thiab txias nyob rau hauv lub tshuab nqus tsev siab, kom lub vapor nag lossis daus ntawm aluminium deposits rau saum npoo ntawm cov yas zaj duab xis, thiaj li hais tias lub nto ntawm cov yas zaj duab xis muaj ib tug metallic luster.Vim nws muaj ob qho tib si cov yam ntxwv ntawm cov yas zaj duab xis thiab hlau, nws yog ib qho pheej yig thiab zoo nkauj, kev ua tau zoo heev thiab cov khoom siv ntim khoom.
Hauv qab no yog cov kev ua yeeb yam ntawm nws:
1.Qhov tshwm sim
Qhov saum npoo ntawmmetalized pre-txheej zaj duab xisyuav tsum tiaj tus thiab du, tsis muaj wrinkles lossis tsuas yog me me ntawm cov pleats nyob;tsis pom tseeb uneven, impurities thiab txhav blocks;tsis muaj cov cim, npuas, qhov thiab lwm yam tsis xws luag;tsis pub pom tseeb glitter, Yin thiab Yang nto thiab lwm yam tshwm sim.
2.Thickness ntawm metalized zaj duab xis
Lub thickness ntawm lubaluminized tshav kub laminating zaj duab xis yuav tsum yog uniform, lub thickness sib txawv ntawm transverse thiab longitudinal yuav tsum yog me me, thiab cov deviation faib yog ntau uniform.Tsis muaj qhov pom tseeb convex tav ntawm lub nruas, txwv tsis pub nws yooj yim rau wrinkle thaum laminating.
3.Thickness ntawm txhuas txheej
Lub thickness ntawm aluminium txheej yog ncaj qha ntsig txog cov cuab yeej barrier ntawm lubmetalized composite zaj duab xis.Nrog rau qhov nce ntawm cov tuab ntawm aluminium txheej, kev xa tawm ntawm cov pa oxygen, dej vapor, lub teeb, thiab lwm yam, maj mam txo qis, thiab sib raug zoo, cov cuab yeej thaiv ntawm aluminium plating zaj duab xis kuj tseem txhim kho.Yog li ntawd, lub thickness ntawm aluminium txheej yuav tsum tau raws li tus qauv yuav tsum tau, thiab lub txheej yuav tsum uniform, txwv tsis pub nws yuav tsis ua kom tiav qhov kev cia siab barrier nyhuv.
4.Adhesion
Aluminium txheej yuav tsum muaj zog adhesion thiab zoo firmness, txwv tsis pub nws yog ib qho yooj yim rau dealuminize thiab ua rau muaj teeb meem zoo.Nyob rau hauv cov txheej txheem ntawm lub tshuab nqus tsev zooaluminium laminating zaj duab xis, ib qho nyiaj ntawm primer kua nplaum yuav tsum tau siv rau ntawm txhuas nto ntawm aluminium puag zaj duab xis ua ntej txhawm rau txhim kho lub zog sib txuas ntawm aluminium txheej thiab substrate zaj duab xis, thiaj li kom ntseeg tau tias cov txheej txheem txhuas ruaj khov thiab tsis yooj yim rau poob. .Tom qab ntawd, txheej txheej txheej txheej aluminium kuj tseem yuav tsum tau coated nrog ob lub ntsiab lus polyurethane nplaum ua cov txheej txheej saum toj kawg nkaus los tiv thaiv cov txheej txheej aluminium los ntawm kev hnav.
5. Lub cev thiab txhua yam khoom
Covmetalized thermal laminating zaj duab xisNws yuav tsum muaj lub zog ntawm cov neeg kho tshuab thaum lub sij hawm ua cov txheej txheem sib xyaw, yog li nws yuav tsum muaj qee yam kev siv zog thiab kev hloov pauv, thiab yuav tsum muaj lub zog tensile zoo, elongation, tearing zog, cuam tshuam lub zog, zoo heev folding kuj thiab toughness thiab lwm yam khoom los xyuas kom meej tias nws Nws tsis yooj yim rau knead, crumple, tawg thiab lwm yam tshwm sim thaum lub sij hawm ua cov khoom sib xyaw.
6.Moisture permeability
Moisture transmittance qhia qhov permeability ntawmaluminium EVA adhesion zaj duab xisrau dej vapor nyob rau hauv tej yam kev mob, uas qhia txog cov dej tsis kam ntawm aluminium thermal laminating zaj duab xis mus rau ib qho twg.Piv txwv li, noo noo permeability ntawm 12 um polyester metalized heat lamination zaj duab xis (VMPET) yog nruab nrab ntawm 0.3g /㎡·24h ~ 0.6g /㎡·24h (kub 30 ℃, txheeb ze av noo 90%);Cov dej noo permeability ntawm CPP aluminized zaj duab xis (VMCPP) nrog lub thickness ntawm 25 um yog nruab nrab ntawm 1.0g /㎡·24h thiab 1.5g /㎡·24h (kub 30 ℃, txheeb ze humidity 90%).
7.Oxygen permeability
Oxygen permeability sawv cev rau tus nqi ntawm cov pa nkag ntawm aluminium thermal lamination zaj duab xis nyob rau hauv tej yam kev mob, uas qhia txog qhov luaj li cas ntawm barrier ntawm metalized thermal lamination zaj duab xis rau oxygen, xws li cov pa permeability ntawm polyester aluminium pre-coated zaj duab xis nrog ib tug tuab. ntawm 25 um yog hais txog 1.24 ml / ㎡ · 24h (kub 23 ℃, txheeb ze av noo yog 90%).
8.Qhov loj ntawm qhov nro saum npoo
Txhawm rau ua kom tus number case thiab cov nplaum nplaum muaj qhov zoo wettability thiab adhesion ntawm qhov chaw ntawm aluminium composite zaj duab xis, nws yuav tsum tau hais tias qhov nro ntawm lub metalized pre-coated zaj duab xis yuav tsum ncav cuag ib tus qauv, txwv tsis pub nws yuav cuam tshuam rau adhesion thiab adhesion ntawm tus number case thiab nplaum rau ntawm qhov chaw, yog li cuam tshuam rau qhov zoo ntawm cov khoom luam tawm thiab cov khoom sib xyaw.Piv txwv li, nto nro ntawm polyesteraluminium thermal lamination zaj duab xis(VMPET) yuav tsum ncav cuag ntau tshaj 45 dynes, tsawg kawg yog 42 dynes.
