Koj puas tau ntsib cov teeb meem zoo li no: ua tib zoo xaiv lub hnab nqus tsev, uas koj xav tias yuav khaws cov khoom tshiab thiab tsw ntawm cov khoom, tab sis vim yog xaiv cov khoom siv tsis raug, lub txee lub neej luv luv, lub ntim tau puas, thiab txawm tias cov khoom lag luam raug cuam tshuam?
Hauv lub ntiaj teb ntawm lub tshuab nqus tsev ntim khoom, kev xaiv cov khoom siv yog thawj kauj ruam tseem ceeb uas txiav txim siab ua tiav lossis tsis ua tiav. Nws cuam tshuam ncaj qha rau cov khoom thaiv, cov khoom siv dag zog, cov nyhuv sealing, nrog rau cov nqi thiab cov duab khoom. Kev xaiv cov khoom siv lub tshuab nqus tsev zoo tsis yog tsuas yog ua kom cov khoom lag luam txee lub neej zoo xwb tab sis kuj tseem txhim kho cov khoom lag luam thiab cov neeg siv khoom ntseeg siab.
Txawm hais tias tib cov ntaub ntawv muaj ntau, lawv qhov kev ua tau zoo yog txwv thiab feem ntau tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua. Piv txwv li, ib lub hnab polyethylene (PE) yooj yooj yim thiab muaj tus nqi qis, tab sis nws qhov kev ua tau zoo ntawm cov pa thiab dej vapor barrier yog qhov nruab nrab. Peb cov ntaub ntawv qhia tau hais tias lub tshuab nqus tsev ntim cov nqaij uas siv lub thickness ntawm PE nyob rau hauv lub tub yees tej zaum yuav muaj ib tug txee lub neej luv luv los ntawm 30% - 50% piv rau ntim nrog siab barrier composite cov ntaub ntawv. Qhov no cuam tshuam ncaj qha rau cov khoom txee lub neej thiab lub peev xwm los txo qhov poob.
Ntau- txheej cov ntaub ntawv sib xyaw yog cov ntsiab lus tseem ceeb rau kev ua haujlwm siab - lub tshuab nqus tsev ntim khoom.
Los ntawm kev sib txuas cov yeeb yaj kiab sib txawv (xws li nylon / PE, polyester / PE, thiab lwm yam), qhov zoo ntawm txhua qhov tuaj yeem ua ke. Piv txwv li:
Polyamide (PA): Muaj kev tiv thaiv zoo heev thiab tawv, ua rau nws tsim nyog rau ntim khoom nrog cov pob txha lossis cov npoo ntse.
Polyester (PET) lossis biaxially oriented polyamide (BOPA): Muab cov hnab ntim nrog cov tawv tawv zoo heev, cov khoom luam ntawv thiab kev ua haujlwm siab roj.
Polyethylene (PE) los yog cua tshuab polypropylene (CPP): Raws li cov cua sov- txheej sealing, nws muab ruaj khov thiab txhim khu kev qha sealing thiab muaj cov dej noo zoo- cov khoom pov thawj.
Kev lag luam xav tau kev ntim khoom tau nce ntxiv, ua rau muaj qhov tshwm sim ntawm cov khoom tshwj xeeb xws li cov pa oxygen siab (EVOH co-extruded film), antibacterial coatings, thiab degradable biobased cov ntaub ntawv (xws li PBAT / PLA composites).
