Yuav Ua Li Cas Xaiv Lub Hnab Zoo Tshaj Plaws: Phau Ntawv Qhia rau Thickness thiab Tshaj
Lub hnab ntim khoom yog qhov tseem ceeb ntawm peb lub neej niaj hnub, tiv thaiv cov khoom, khaws cia tshiab, thiab txhim kho peb cov kev paub txog kev yuav khoom. Thaum xaiv lub hnab ntim, tuab, ntsuas hauv micrometers (μm), yog qhov tseem ceeb uas cuam tshuam rau kev ua haujlwm ntev, nqi, thiab kev ua haujlwm.
Sib npaug Thickness thiab Performance
Cov hnab ntim khoom feem ntau yog los ntawm 50 - 100 μm. Piv txwv li, ntau lub hnab ntim khoom noj, zoo li cov rau granola tuav, yog 60 - 80 μm tuab. Qhov thickness no sib npaug zog thiab pheej yig. Cov hnab nyias nyias (tsawg dua 50 μm) txuag cov nqi tab sis tsis muaj kev ntseeg siab, thaum lub hnab ntim ntau tshaj 100 μm tuaj yeem loj heev thiab kim.
Thickness rau kev siv sib txawv
Kev txuag zaub mov: Cov khoom uas ploj mus zoo li cov ntses tshiab xav tau 80 - 120 μm barrier films los thaiv cov pa. Cov khoom qhuav xws li kas fes taum zoo - tiv thaiv los ntawm 60 - 80 μm hnab nrog cov zippers rov qab.
Kev ntim khoom lag luam: Cov khoom siv hluav taws xob me me siv 50 - 70 μm los tiv thaiv - lub hnab zoo li qub, thaum cov khoom siv rooj tog loj yuav tsum muaj corrugated thawv sib npaug rau 1000 - 1500 μm rau kev tiv thaiv.
Cov khoom txhua hnub: Hloov chaw ntawm cov hnab polyethylene, ntau eco - cov neeg tau txais kev paub tam sim no tig mus rau lwm txoj hauv kev xws li PLA (polylactic acid) thiab PBAT (polybutylene adipate terephthalate) hnab. Cov nroj tsuag no - raws li cov ntaub ntawv, feem ntau siv rau hauv 50 - 70 μm thicknesses rau cov khoom xws li cov ntaub so ntswg thiab cov ntaub so ntswg ntim, muab cov dej noo zoo heev thiab maj mam rau ib puag ncig. Cov hnab ntim khoom siv rov siv tau ua los ntawm kev sib xyaw ntawm PLA thiab PBAT, feem ntau nyob ib puag ncig 80 - 100 μm, sib txuas ua haujlwm ntev nrog eco - tus phooj ywg, muab kev xaiv ruaj khov rau kev siv txhua hnub.
Lwm Cov Kev Txiav Txim Siab
Khoom sivs: Tsis zoo li cov yas yas, PLA yog muab los ntawm cov khoom siv txuas ntxiv dua tshiab xws li cov hmoov nplej pob kws, muab cov rigidity zoo thiab pob tshab tab sis nrog qee qhov kev txwv nyob rau hauv qis - kub hloov tau. PBAT, ntawm qhov tod tes, yog qhov hloov tau yooj yim thiab muaj cov yeeb yaj kiab zoo heev - tsim cov khoom. Kev sib xyaw ob cov ntaub ntawv no tsim cov khoom ntim ntau yam uas tuaj yeem hloov kho rau ntau yam kev siv. Cov khoom lag luam tau nce zuj zus los ntawm PVC thiab polyethylene hauv kev pom zoo ntawm PLA thiab PBAT kev xaiv ntau dua vim muaj kev txhawj xeeb ib puag ncig.
Kev tsim khoom:Kev tswj kom zoo thaum lub sijhawm tsim khoom ua kom cov tuab tuab thiab du nto rau PLA thiab PBAT hnab, tiv thaiv cov teeb meem tsis muaj zog. Cov txheej txheem tsim tshwj xeeb yog siv los txhim kho kev ua tau zoo ntawm cov bio - cov ntaub ntawv raws li, xyuas kom lawv ua tau raws li - cov qauv zoo.
Ib puag ncig:Nrog nce eco - kev paub, cov neeg siv khoom nquag nrhiav kev ntim khoom los ntawm cov khoom siv biodegradable thiab compostable. PLA thiab PBAT hnab yog tsim los ua kom tawg raws li ib puag ncig ib puag ncig, txo lub nra ntawm qhov chaw pov tseg thiab dej hiav txwv piv rau cov khoom siv niaj hnub.
