Xyoo 1911 yog lub sijhawm tseem ceeb hauv keeb kwm ntawm lub ntiaj teb ntim khoom noj.Vim hais tias xyoo no yog lub xyoo debut ntawm txhuas ntawv ci nyob rau hauv lub tshav pob ntawm cov zaub mov, thiab yog li pib nws txoj kev zoo kawg nkaus taug kev nyob rau hauv lub tshav pob ntawm cov zaub mov.Raws li ib tug pioneer hauvaluminium foil ntim, ib lub tuam txhab Swiss chocolate tau loj hlob tshaj 100 xyoo thiab tam sim no tau dhau los ua lub npe nrov (Toblerone).
Aluminium ntawv nyiajfeem ntau yog hais txog txhuas nrog lub purity ntawm ntau tshaj 99.5% thiab ib tug tuab ntawm tsawg tshaj li 0.2 millimeters, thaum txhuas ntawv ci siv rau composite cov ntaub ntawv muaj ib tug nyias thickness.Tau kawg, ntau lub teb chaws muaj cov kev cai sib txawv rau cov tuab thiab muaj pes tsawg leeg ntawm aluminium ntawv ci.Cov lus nug yog, puas tuaj yeem txhuas ntawv ci, nyias li cicada tis, muaj peev xwm ua tau haujlwm tseem ceeb ntawm kev ntim khoom noj?Qhov no kuj pib nrog lub hom phiaj ntawm kev ntim khoom noj thiab cov yam ntxwv ntawm aluminium ntawv ci.Txawm hais tias ntim khoom noj feem ntau tsis tuaj yeem noj tau, nws yog ib qho tseem ceeb ntawm cov khoom noj khoom haus.Hais txog kev ua haujlwm ntawm kev ntim khoom noj, qhov tseem ceeb tshaj plaws yog kev tiv thaiv zaub mov muaj nuj nqi.Cov zaub mov tau dhau los ua cov txheej txheem nyuaj los ntawm kev tsim khoom mus rau kev noj, uas tej zaum yuav cuam tshuam los ntawm lwm yam xws li biology, chemistry, thiab physics hauv ib puag ncig.Kev ntim khoom noj yuav tsum muaj peev xwm tswj tau qhov ruaj khov ntawm cov zaub mov zoo thiab tiv thaiv ntau yam kev tsis zoo hauv ib puag ncig.Nyob rau tib lub sijhawm, ntim khoom noj yuav tsum ua kom tau raws li qhov xav tau ntawm kev zoo nkauj, kev yooj yim, kev tiv thaiv ib puag ncig, thiab kev pheej yig.
Cia peb saib cov yam ntxwv ntawmaluminium ntawv cidua.Ua ntej, aluminium ntawv ci muaj lub zog txhua yam thiab qee qhov cuam tshuam thiab puncture kuj.Yog li ntawd, thaum lub sij hawm cia, tsheb thauj mus los, thiab lwm yam txheej txheem,aluminium foil ntim khoom nojtsis yooj yim puas vim muaj tej yam xws li compression, cuam tshuam, vibration, kub sib txawv, thiab lwm yam. Secondly, aluminium ntawv ci muaj siab barrier kev ua tau zoo, uas yog heev resistant rau tshav ntuj, kub kub, noo noo, oxygen, microorganisms, thiab lwm yam. txhua yam uas txhawb nqa zaub mov tsis zoo, thiab thaiv cov xwm txheej no tuaj yeem ua rau lub neej txee ntawm zaub mov.Thib peb, aluminium ntawv ci yog ib qho yooj yim rau txheej txheem thiab muaj tus nqi qis, uas tuaj yeem ua tau raws li qhov xav tau ntim ntawm cov khoom noj feem ntau thiab muaj cov xim dawb zoo nkauj thiab cov xim tsis zoo.Plaub, hlau aluminium nws tus kheej yog cov hlau hnyav, thiab cov ntawv txhuas nyias nyias ua tau raws li qhov yuav tsum tau ua ntawm lub teeb yuag, uas yog qhov tseem ceeb rau kev txo nqi tsheb thauj mus los.Thib tsib, aluminium ntawv ci yog tsis muaj tshuaj lom thiab tsis muaj ntxhiab, yooj yim rau rov siv dua, thiab ua tau raws li cov kev cai ntawm kev tiv thaiv ib puag ncig ntsuab thiab kev txhim kho kom ruaj khov.
Txawm li cas los xij, hauv kev xyaum ntim khoom noj,aluminium ntawv cifeem ntau tsis tshua siv ib leeg, vim tias txhuas ntawv ci nws tus kheej kuj muaj qee qhov tsis zoo.Piv txwv li, raws li cov ntawv txhuas txhuas yog thinned ntxiv, cov pores yuav nce ntxiv, uas yuav cuam tshuam rau kev ua haujlwm ntawm cov ntawv ci txhuas.Lub caij no, lub teeb yuag thiab mos aluminium ntawv ci muaj cov kev txwv ntawm tensile thiab shear resistance, thiab feem ntau tsis haum rau kev ntim khoom.Hmoov zoo, aluminium ntawv ci muaj qhov ua tau zoo tshaj plaws theem nrab ua haujlwm.Feem ntau, cov ntaub ntawv ntim khoom sib xyaw tuaj yeem tsim los ntawm kev sib txuas cov ntawv txhuas txhuas nrog rau lwm cov ntaub ntawv ntim khoom kom ua rau qhov tsis zoo ntawm aluminium ntawv ci thiab txhim kho cov khoom ntim zoo ntawm cov khoom ntim khoom sib xyaw.
Peb feem ntau xa mus rau ib zaj duab xis uas muaj ob los yog ntau tshaj cov ntaub ntawv raws li ib tug composite zaj duab xis, thiab ib lub hnab ntim khoom los ntawm composite zaj duab xis yog hu ua ib tug composite film bag.Feem ntau, yas,aluminium ntawv ci, ntawv thiab lwm yam ntaub ntawv tuaj yeem ua rau hauv cov yeeb yaj kiab sib xyaw los ntawm kev sib txuas los yog kev sib khi kom sov kom tau raws li qhov sib txawv ntim xav tau ntawm ntau yam khoom noj.Hauv kev ntim khoom niaj hnub no, yuav luag tag nrho cov khoom sib xyaw uas yuav tsum tau ua kom tsis muaj teeb pom kev zoo thiab muaj kev tiv thaiv siabaluminium ntawv ci li barrier txheej, vim tias cov ntawv txhuas txhuas muaj cov qauv hlau siv lead ua zoo heev thiab muaj kev cuam tshuam zoo rau txhua qhov roj.
Hauv cov khoom ntim khoom muag, muaj cov khoom ntim hu ua "nqus aluminized film".Puas yog tib yam lialuminium foil composite ntim khoom?Txawm hais tias ob qho tib si muaj txheej nyias nyias ntawm txhuas, lawv tsis yog cov khoom qub.Lub tshuab nqus tsev aluminium plating zaj duab xis yog ib txoj hauv kev ntawm evaporating thiab tso siab purity aluminium mus rau cov yas zaj duab xis hauv lub tshuab nqus tsev, thaumaluminium foil composite khoomyog tsim los ntawm aluminium ntawv ci thiab lwm yam ntaub ntawv los ntawm kev sib txuas los yog thermal bonding.
Tsis zoo lialuminium foil composite cov ntaub ntawv, aluminium txheej hauv aluminium plated zaj duab xis tsis muaj qhov cuam tshuam ntawm aluminium ntawv ci, tab sis theej substrate zaj duab xis nws tus kheej.Raws li cov txheej txheem aluminized yog thinner dua aluminium ntawv ci, tus nqi ntawm aluminized zaj duab xis yog qis dua li ntawmaluminium foil composite khoom, thiab nws daim ntawv thov kev lag luam kuj yog dav heev, tab sis nws feem ntau tsis siv rau lub tshuab nqus tsev ntim khoom.
