Matumba owonongeka ndi mtundu waposachedwa wa matumba okometsera zachilengedwe.Matumba biodegradable akhoza kupangidwa molingana ndi nthawi kuwonongeka amafuna makasitomala, amene akhoza kugawidwa mu matumba kwathunthu degradable (100% degradable mkati 3 months) ndi matumba degradable (6-12 miyezi).Nthawi yomweyo, imatha kupereka mitundu yosiyanasiyana komanso kusindikiza kosangalatsa, komwe kumagwiritsidwa ntchito m'malo mwa kulongedza mafilimu apulasitiki monga PE, PP, PO, etc., kuti akwaniritse zofunikira zoteteza zachilengedwe padziko lapansi, ndipo zimatha kupanga matumba, zikwama za Arc, zikwama zam'manja, malo ogulitsira, matumba a ziplock, etc.
Zida zopangira matumba owonongeka ndi bio-based, zomwe zimatanthawuza gulu latsopano la zinthu zopangidwa ndi biology, mankhwala ndi njira zakuthupi pogwiritsa ntchito biomass yongowonjezedwanso, kuphatikiza mbewu, mitengo ndi mbewu zina ndi zotsalira ndi zomwe zili mkati mwake monga zopangira.M'manda achilengedwe kapena malo opangira kompositi komwe kuli tizilombo tating'onoting'ono, imatha kuwola kukhala carbon dioxide ndi madzi popanda kuipitsa chilengedwe.Mwachitsanzo, polylactic acid/polyhydroxyalkanoate/starch/cellulose/straw/chitin ndi gelatin zili m’gululi.Zopangira zamoyo zimatchula zinyalala zaulimi ndi nkhalango za lignocellulosic monga udzu osati tirigu.
Zopangira zazikulu za thumba losawonongeka ndi PLA/PBAT monga zoyambira, monga mbewu, mapadi, chimanga ndi wowuma wa mbatata wopangidwa ndi nayonso mphamvu.Amagwiritsidwa ntchito kwambiri pakuyika, filimu yaulimi, tableware, zofunikira zatsiku ndi tsiku komanso chithandizo chamankhwala.
Kodi biomatadium ndi chiyani?
Biomaterials ndi mawu ophatikiza mapulasitiki opangidwa ndi bio-based ndi mapulasitiki owonongeka:
Mapulasitiki okhala ndi bio: mapulasitiki opangidwa kuchokera kuzinthu zongowonjezwdwa.Mosiyana ndi mapulasitiki achikhalidwe, ma polima opangidwa ndi bio amachokera ku zinthu zongowonjezwdwa, monga shuga, wowuma, mafuta a masamba, mapadi, etc. Pakati pawo, chimanga, nzimbe, tirigu, ndi nkhuni ndizo zomwe zimagwiritsidwa ntchito kwambiri.
Zambiri zamalonda:
Mtundu: matumba ogula, matumba a zinyalala, matumba onyamula, matumba a zovala, matumba odzimatira, matumba a mafupa, ndi zina zotero.
Kugwiritsa ntchito: zinthu zapakhomo, zofunikira zatsiku ndi tsiku
Zosamalidwa bwino ndi chilengedwe, zimatha kuwonongeka kwathunthu
Zida: PBAT, Cornstarch, PLA
Biodegradability: 100% biodegradable
Mtundu: wosankha/mwamakonda
Zofotokozera: Zosinthidwa mwamakonda
