Nrog rau kev loj hlob sai ntawm peb lub neej,PLA ntawv khobtab tom ua nrov.Kas fes thiab mis nyuj tshuaj yej muaj kev lag luam zoo, cov khob ntawv pov tseg thiab lub hau tau ua haujlwm zoo rau nws.Feem ntau ntawm cov neeg siv khoom nyiam siv PLA ntawv khob, vim tias daim ntawv PLA tsis muaj dej, thiab nws tuaj yeem tuav cov khob kom qhuav, nyab xeeb thiab tsis muaj mob.Qhov zoo ntawm PLA ntawv khob yuav qhia hauv qab no.

1.PLA ntawv khobmuaj dej tsis kam, zoo huab cua permeability.Lub khob no muaj lub zog saum npoo siab thiab lub zog interlaminar, vim tias qhov nkag mus yog siab dua lwm cov ntaub ntawv.PLA ntawv khob yog cov tshuaj tua kab mob, thiab tuaj yeem nqus tau ammonia.

2. Qhov noeco tus phooj ywg ntawv khob lag luam wholesalebelongs rau daim ntawv zaub mov, thiab nws muaj qhov zoo ntawm mildew pov thawj, dej nqus thiab dej tsis kam.Cov ntaub qhwv zaj duab xis yog tsim los ntawm cov txheej txheem tshwj xeeb nrog cov protein ua txheej rau ntawm daim ntawv, uas tuaj yeem tiv taus qhov kub thiab txias, tiv thaiv kev yaig, yooj yim rau kev ua zaub mov, thiab tsis muaj kuab paug rau ib puag ncig.

3. Polylactic acid (PLA) yog cov khoom siv biodegradable tshiab thiab rov ua dua tshiab, uas yog tsim los ntawm cov hmoov txhuv nplej siab los ntawm cov khoom siv cog qoob loo (xws li pob kws, cassava, thiab lwm yam).Cov hmoov txhuv nplej siab yog saccharized kom tau cov piam thaj, uas yog tom qab ntawd fermented los ntawm qee yam kab mob los tsim cov purity lactic acid, thiab ces cov lactic acid yog synthesized kom tau polylactic acid.PLApov tseg daim ntawv khobmuaj biodegradability zoo thiab tuaj yeem degraded tag nrho rau carbon dioxide thiab dej los ntawm cov kab mob hauv cov kab mob hauv cov xwm txheej tshwj xeeb, ua rau tsis muaj kuab paug rau ib puag ncig.

PLA daim ntawv khob siv cov khoom siv hluav taws xob txuas ntxiv dua tshiab los ua cov khoom siv raw, uas txo qhov kev cia siab ntawm cov khoom siv roj ib txwm muaj thiab ua raws li qhov yuav tsum tau muaj ntawm kev txhim kho thoob ntiaj teb.Nws muaj ob qho tib si zoo ntawm hluavtaws fiber ntau thiab ntuj fiber ntau, thiab cov yam ntxwv hauv kev ua kom zoo nkauj thiab lom lom.Piv nrog cov pa fiber ntau, pob kws fiber ntau muaj ntau yam khoom tshwj xeeb, ua rau nws nyiam thiab muaj nuj nqis los ntawm cov neeg siv khoom.
