Lub tshuab nqus tsev ntim khoom thiab hloov pauv huab cua ntim yuav tsum muaj kev cuam tshuam siab ntawm cov khoom ntim. Nws yog ib qho tseem ceeb kom muaj kev ruaj khov nyob rau hauv ib puag ncig roj; Nruam ingress ntawm sab nraud oxygen cuam tshuam rau xim, aroma thiab zuag qhia tag nrho cov khoom noj.
EVOH high barrier membrane yog cov txheej txheem tseem ceeb ntawm cov txheej txheem sib xyaw ua ke siv los ntim cov khoom noj nqaij, nqaij nruab deg, cheese thiab lwm yam khoom noj uas yuav tsum tau tswj cov pa oxygen.
Raws li keeb kwm yav dhau los ntawm kev loj hlob sai ntawm cov khoom noj khoom haus tshiab thiab ntim khoom ua ntej, cov tuam txhab tau them nyiaj tsis yog rau kev ntim khoom zoo nkauj xwb, tab sis kuj tseem cuam tshuam rau kev ua tau zoo, sealing kev ncaj ncees thiab kev ua haujlwm zoo. Yog li ntawd, kev sib txuas EVOH nrog cov ntaub ntawv xws li PE thiab PP los ua ntau yam - txheej ntim cov qauv tau dhau los ua ib txoj hauv kev siv. Muaj peev xwm loj hauv kev ntim tshuaj thiab kev kho mob
3. Cov khoom lag luam xav tau kev ruaj ntseg siab thiab kev tiv thaiv muaj peev xwm ntawm cov khoom ntim, tshwj xeeb tshaj yog cov rhiab rau cov pa oxygen, uas yuav tsum muaj cov khoom thaiv zoo heev.
EVOH tuaj yeem siv los ua txheej txheej thaiv rau cov tshuaj lossis kev ntim khoom kho mob kom txo tau cov pa oxygen permeation thiab tsim kom muaj kev ruaj ntseg rau cov khoom. Cov ntawv thov tshwj xeeb yuav tsum tau xaiv cov khoom siv thiab siv tau raws li cov yam ntxwv ntawm cov tshuaj, cov qauv ntim khoom thiab cov kev cai tswj hwm.
Nrog rau kev thov kom muaj kev nyab xeeb, kev ruaj ntseg thiab cov khoom siv ntawm kev ntim tshuaj, kev siv cov yeeb yaj kiab siab hauv kev ntim tshuaj, cov khoom ntim sib xyaw thiab qee cov khoom siv kho mob yuav nce ntxiv.
4. Ntim cov tshuaj hauv tsev thiab cov khoom siv tu tus kheej
Tshuaj pleev ib ce, khoom siv tu tawv nqaij, khoom siv hauv tsev thiab ntau yam khoom siv tu tus kheej kuj yuav tsum tau tiv thaiv los ntawm lwm qhov chaw ib puag ncig thaum khaws cia.
Rau cov khoom uas raug oxidation los yog yuav tsum tau tshwj xeeb barrier kev ua tau zoo, ib tug multi- txheej ntim cov qauv nrog ib tug EVOH barrier txheej yuav ua hauj lwm los txhim kho kev tiv thaiv ntawm oxygen thiab lwm yam sab nraud.
Nyob rau tib lub sijhawm, cov neeg siv khoom tau nce ntxiv nrhiav ntim rau kev zoo nkauj, pob tshab, tsim qauv hnyav thiab nqa tau yooj yim. Piv nrog rau cov khoom siv tiv thaiv siab ib txwm muaj, EVOH ntau- txheej cov yeeb yaj kiab muaj kev cuam tshuam zoo tshaj plaws thaum muab cov qauv ntim tau yooj yim dua.
5. Cov Khoom Noj Tsiaj & Cov Khoom Siv Ua Lag Luam Zoo Tshaj Plaws
Nyob rau hauv xyoo tas los no, cov khoom noj tsiaj ntim rau kev ua haujlwm siab, portable, kev txhim kho kev ua haujlwm. Cov khoom noj ntub dej, nqaij, cov zaub mov tsiaj thiab siab - cov khoom muaj roj yuav tsum tau tswj nruj me ntsis ntawm cov pa oxygen thiab noo noo thaum khaws cia.
EVOH cov ntaub thaiv npog siab tuaj yeem siv rau hauv cov hnab ntim khoom noj, cov ntim khoom muag thiab cov tais, siv ntau txheej los muab cov kev tiv thaiv tsim nyog.
Tsis tas li ntawd, cov khoom xws li kas fes, txiv ntseej, nqaij thiab cheese muaj cov pa oxygen siab. Nrog rau kev nthuav dav ntawm siab -txheej txheem kev lag luam muag muag, EVOH daim ntawv thov yuav nthuav dav tshaj li cov khoom ntim khoom noj rau ntau yam khoom siv rau kev khaws cia.
6. Sustainable lub teeb yuag packaging Lub teeb yuag yuag kom tsav kev hloov kho dua tshiab
Kev txhim kho yav tom ntej ntawm EVOH cov yeeb yaj kiab siab barrier yuav tsom tsis yog tsuas yog kev cuam tshuam kev ua haujlwm, tab sis kuj nce ntxiv ntawm cov khoom siv txo qis, lub teeb yuag, thiab rov ua dua tshiab. Cov tsoos siab- cov khoom ntim khoom ntim yuav cia siab rau cov qauv sib xyaw ua ke, thiab EVOH, nrog rau lwm cov polymers, ua raws li cov txheej txheem txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej, txo cov kev siv cov ntaub ntawv thaum ua tau raws li qhov yuav tsum tau ua.
Cov kev lag luam yav tom ntej yuav nce siab ntxiv rau EVOH daim ntawv thov hauv mono-cov khoom siv, cov qauv ntim rov ua dua tshiab, rub tawm (thinning) ntim, thiab ntau dua. Txawm li cas los xij, kev rov ua dua tshiab thiab cov qauv kev xaiv yog nyob ntawm cov khoom siv rov ua dua tshiab hauv zos, cov khoom sib xyaw ua ke thiab cov qauv ntim tshwj xeeb; Nws tsis tuaj yeem tsuas yog xav tau tias txhua lub ntim ntim uas muaj cov organic sib txuas ncaj qha tuaj yeem rov ua dua tshiab.
Rau cov tuam txhab ntim khoom, lub hom phiaj yav tom ntej yuav ua rau muaj kev sib npaug ntawm kev ua haujlwm ntawm oxygen barrier, mechanical zog, thermalsealing kev ua tau zoo, cov khoom siv thiab sustainability los ntawm optimizing EVOH cov ntsiab lus, membrane qauv thiab ua technology.
