Zinthu Zowonongeka Zowonongeka

Biodegradable zipangizo ndi zipangizo kuti akhoza kwathunthu wosweka mu otsika maselo mankhwala ndi tizilombo (mwachitsanzo, mabakiteriya, bowa, ndi algae, etc.) pansi pa chilengedwe chilengedwe mikhalidwe yoyenera ndi demonstrable nthawi. Pakalipano, amagawidwa makamaka m'magulu anayi: polylactic acid (PLA), PBS, polylactic acid ester (PHA) ndi polylactic acid ester (PBAT).

PLA ili ndi biosafety, biodegradability, makina abwino komanso kukonza kosavuta, ndipo imagwiritsidwa ntchito kwambiri pakuyika, nsalu, mafilimu apulasitiki aulimi komanso mafakitale a polima.

PBS ingagwiritsidwe ntchito poyika filimu, ma tableware, zonyamula thovu, mabotolo ogwiritsira ntchito tsiku ndi tsiku, mabotolo amankhwala, mafilimu aulimi, feteleza wophera tizilombo omwe amatulutsidwa pang'onopang'ono ndi zinthu zina.

PHA ingagwiritsidwe ntchito pazinthu zowonongeka, zovala zopangira opaleshoni ya zipangizo zamankhwala, matumba onyamula ndi kompositi, sutures zachipatala, zipangizo zokonzekera, mabandeji, singano za mafupa, mafilimu odana ndi adhesion ndi stents.

PBAT ili ndi ubwino wochita bwino kupanga mafilimu komanso kuwomba filimu kosavuta, ndipo imagwiritsidwa ntchito kwambiri m'makanema onyamula katundu ndi mafilimu alimi.
