Imithombo Ebonakalayo Engaphezulu Eluhlaza
Izinto ezivuthiwe ezisetshenziselwa ukukhiqiza i-polylactic acid (PLA) zivela ezinsizakalweni ezivuselelekayo ezinjenge-corn, ngaphandle kwesidingo sezinsizakusebenza zemvelo ezinjenge-petroleum noma ngokhuni, ngaleyo ndlela zisiza ukuvikela izinsiza zokunciphisa amafutha.
Izakhiwo Eziphakeme Zomzimba
I-PLA ilungele izindlela ezahlukahlukene zokucubungula ezifana nokubumba kokubumba kanye nama-thermoplastics, okwenza kube lula ukucubungula futhi isebenze kunhlobonhlobo yemikhiqizo yepulasitiki, ukufakwa kwamabhokisi okudla, izindwangu ezingezinwebe, futhi zinombono wemakethe othembisayo.
Biocomthation
I-PLA nayo inokuthambekela okuhle kakhulu, nomkhiqizo wayo wokucekelwa phansi, i-L-lactic acid, ingabamba iqhaza kumetabolism yabantu. Kuvunyelwe yi-US Food and Drug Administration (FDA) futhi ingasetshenziswa njenge-suputure yokuhlinzwa, amaphilisi okujoyika, ama-microsros, kanye nezimila.
Ukuphefumula okuhle
Ifilimu ye-PLA inokuphefumula okuhle, ukuphefumula komoya-mpilo, kanye ne-carbon dioxide permeability, futhi kunesimo sephunga lokuhlukaniswa kwephunga. Amagciwane nesikhunta kulula ukunamathisela ebusweni beplastiki ye-biodegradable, ngakho-ke kukhona ukukhathazeka ngokuphepha nokuhlanzeka. Kodwa-ke, i-PLA ukuphela kwepulasitiki engathandeki enezakhiwo ezinhle kakhulu ze-antibacterial ne-anti-mold.
Biodegradeability
I-PLA ingenye yezinto zokucwaninga kakhulu ze-bioderlines eChina nakwamanye amazwe, futhi izindawo zayo ezintathu ezinkulu zokushisa ziwukupakishwa kokudla, itafula elahlwayo, kanye nezinto zokwelashwa.
I-PLA, eyenziwe ikakhulukazi kusuka ku-National Lactic Acid, ine-biodegradatity enhle kanye ne-biocomtic, futhi umjikelezo wawo wempilo unomthelela ophansi wezemvelo ophansi kakhulu kunezinto zokwakha uphethiloli. Kubhekwa njengento ethembisa kakhulu yokufaka okuluhlaza okwesibhakabhaka entuthukweni.
Njengohlobo olusha lwezinto ezihlanzekile zebhayoloji, i-PLA inamathemba amakhulu emakethe. Izakhiwo zalo ezinhle kanye nobungani bezemvelo kuzobe kungazenzela ukuthi usetshenziswe kabanzi ngokuzayo.
