Taw qhia: PBAT, luv luv rau poly (butylene adipate-co-terephthalate), yog ib nrab-crystalline polymer paub txog nws cov biodegradability zoo heev thiab txhua yam khoom. Nws yog copolymer ntawm aliphatic thiab aromatic polyesters, sib txuas cov yam ntxwv ntawm ob qho tib si. Nrog lub crystallinity ntawm ib ncig ntawm 30%, PBAT nthuav tawm qhov kub thiab txias ntawm kwv yees li 110 degree thiab qhov chaw melting ntawm txog 130 degree. Nws qhov ceev yog li ntawm 1.18g / ml mus rau 1.3g / ml, thiab nws muaj ntug hiav txwv hardness tshaj 85.
Cov Khoom thiab Cov Qauv: PBAT yog cov yas thermoplastic biodegradable uas muaj cov khoom sib xyaw tshwj xeeb. Nws muaj qhov zoo ductility thiab elongation thaum so, nrog rau kev ua kom sov siab thiab ua rau muaj zog. Qhov no ua rau nws haum rau ntau yam kev siv. Cov qauv copolymer ntawm PBAT tso cai rau nws khaws cov khoom degradation zoo heev ntawm aliphatic polyesters thiab cov neeg kho tshuab lub zog ntawm aromatic polyesters.
Biodegradability: Ib qho ntawm qhov zoo tshaj plaws ntawm PBAT yog nws biodegradability. Nws suav hais tias yog cov khoom siv compostable uas ua raws li EN13432 tus qauv. Nyob rau hauv tej yam kev mob composting, xws li ib tug txheeb ze av ntawm ib ncig ntawm 70% thiab ib tug kub ntawm kwv yees li 60 degree nyob rau hauv ib tug compost chaw uas muaj ntau cov kab mob, PBAT tuaj yeem ua tiav txog li 90% compostability. Thaum lub sij hawm degradation txheej txheem, PBAT tawg rau hauv dej (H2O) thiab carbon dioxide (CO2). Qhov no ua rau PBAT yog ib qho kev hloov hauv eco-phooj ywg rau cov khoom siv yas, pab daws qhov teeb meem ntawm cov pa phem.
Daim Ntawv Thov: PBAT tau pom cov ntawv thov hauv ntau qhov kev lag luam vim nws cov khoom siv ntau yam thiab biodegradability. Qee qhov kev siv feem ntau ntawm PBAT suav nrog:
- Mulching Zaj duab xis: PBAT yog siv dav hauv kev ua liaj ua teb raws li mulching zaj duab xis. Nws pab tswj cov nroj tsuag kev loj hlob, txuag av noo, thiab txhim kho qoob loo. Tom qab siv, cov mulching zaj duab xis tuaj yeem ua tau composted, txo cov khib nyiab thiab ib puag ncig.
- Ntim Zaj duab xis: PBAT yog ib qho khoom siv zoo heev rau kev tsim cov yeeb yaj kiab ntim. Nws muaj lub zog zoo txhua yam thiab hloov tau yooj yim, ua kom muaj kev tiv thaiv thiab khaws cia cov khoom ntim khoom. Tsis tas li ntawd, nws cov biodegradability ua rau nws yog ib qho kev xaiv txaus nyiam rau cov kev daws teeb meem ntim.
- Lub hnab ntim khoom thiab Shipping Hnab: PBAT tuaj yeem siv los tsim cov hnab ntim khoom noj khoom haus thiab cov hnab xa khoom. Cov hnab no muab tib theem ntawm kev ua haujlwm thiab ua haujlwm ntev li cov hnab yas ib txwm muaj tab sis muaj kev cuam tshuam ib puag ncig qis dua.
- Cov Khoom Siv Textile: PBAT kuj tseem siv rau hauv kev tsim cov khoom siv textile xws li gauze thiab lub ntsej muag lub ntsej muag. Nws zoo heev biodegradability thiab mechanical zog ua rau nws haum rau cov ntaub ntawv pov tseg cov ntaub ntawv.
- Disposable Cutleries: PBAT-raws li cov cutlery pov tseg, xws li diav rawg, diav, thiab riam, muaj lwm txoj hauv kev rau kev siv cov yas cutleries. Lawv muab cov haujlwm tsim nyog thaum ua biodegradable thiab ib puag ncig tus phooj ywg.
Xaus: PBAT yog ntau yam thiab biodegradable polymer uas sib txuas cov khoom tsim nyog ntawm aliphatic thiab aromatic polyesters. Nws zoo heev biodegradability, txhua yam muaj zog, thiab tshav kub kuj ua rau nws xaiv rau ntau yam kev siv. Los ntawm mulching zaj duab xis mus rau lub hnab yuav khoom thiab cov khoom siv pov tseg, PBAT muab cov kev daws teeb meem zoo los txo cov pa phem. Raws li qhov kev thov rau cov khoom siv biodegradable tseem nce ntxiv, PBAT xav tias yuav ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa lub neej yav tom ntej.
