Thaum koj unwrap koj takeout, thawj yam uas koj feem ntau ntsib yog pob tshab los yog translucent yas ntim. Hom ntim no feem ntau yog tsim los ntawm polypropylene (PP) lossis polyethylene (PE); lub qub yog feem ntau pom nyob rau hauv cov thawv ntim khoom noj, thaum lub tom kawg yog dav siv rau cov hnab yas. PP yog kub heev- tiv taus (sab kub siab tshaj 120 degree), ua rau nws haum rau tuav cov zaub mov kub tsis yooj yim deforming; PE, hloov pauv, yog mos thiab sib sib zog nqus, nquag siv rau cov hnab ntim rov qab los yog cling zaj duab xis. Txawm li cas los xij, qhov tsis zoo ntawm lub ntim yas yog nws qhov tsis kam rau degradation; Tsis tas li ntawd, qee cov plastics tsis zoo yuav muaj cov yas yas, ua rau muaj kev pheej hmoo rau kev noj qab haus huv los ntawm kev sib cuag nrog zaub mov ntev.
Daim ntawv-Plastic Composites: Ib qho "Intermediate Solution" Balancing Eco-Plasticity thiab Practicality
Nyob rau hauv xyoo tas los no, daim ntawv - cov khoom ntim yas sib xyaw tau txais kev muaj koob meej. Hom ntim no nta ib txheej txheej ntawm kraft daim ntawv sib koom ua ke rau ib sab hauv ntawm PE lossis txhuas ntawv ci, muab cov roj thiab dej tsis kam thaum khaws cov ntawv zoo. Cov piv txwv xws li cov thawv hamburger txheem thiab lub tsho kas fes khob. Qhov kom zoo dua ntawm daim ntawv- cov khoom siv yas yog nyob rau hauv lawv cov khoom siv rov ua dua qub dua piv rau cov yas ntshiab, nrog rau lawv lub peev xwm ua kom zoo nkauj dua cov qauv luam tawm. Txawm li cas los xij, lawv qhov tsis zoo suav nrog cov nqi tsim khoom ntau dua; Tsis tas li ntawd, vim qee cov txheej txheem tseem muaj cov khoom siv yas, lawv feem ntau xav tau kev ua haujlwm tshwj xeeb thaum rov ua dua tshiab.
Bio-raws li cov ntaub ntawv: "Tshiab Nyiam" ntawm Cov Ntim Yav Tom Ntej
Raws li kev paub txog ib puag ncig txuas ntxiv nce ntxiv, bio-cov ntaub ntawv raws li- xws li pob kws hmoov txhuv nplej siab thiab qab zib bagasse- tau pib ua inroads mus rau hauv cov khoom nqa tawm. Hom ntim no yog ib txwm biodegradable thiab ua kom qis carbon emissions thaum lub sij hawm tsim khoom. Piv txwv li, qee lub npe tau qhia "cov thawv ntim khoom noj uas tsis zoo" ua los ntawm cov nroj tsuag fibers, uas tuaj yeem decompose tag nrho hauv 3 mus rau 6 lub hlis thaum muab faus rau hauv av. Txawm li cas los xij, qhov kub thiab txias tsis kam ntawm bio- cov ntaub ntawv tseem xav tau kev ua kom zoo dua ntxiv; tam sim no, lawv feem ntau yog siv rau cov khoom noj txias lossis luv luv - daim ntawv thov khaws cia, thiab lawv cov nqi tseem tshuav ob mus rau peb npaug ntau dua li cov qauv yas.
