Imithombo eminingi yezinto ezingavuthiwe
Izinto ezingavuthiwe ezisetshenziselwa ukukhiqiza i-polylactic acid (PLA) zivela ezinsizeni ezivuselelekayo njengommbila, ngaphandle kwesidingo semithombo yemvelo eyigugu njenge-petroleum noma ukhuni, ngaleyo ndlela kusiza ukuvikela izinsiza zikawoyela ezinciphayo.
Izakhiwo zomzimba eziphakeme
I-PLA ilungele izindlela ezahlukahlukene zokucubungula ezifana nokubunjwa kokushaywa kanye ne-thermoplastics, okwenza kube lula ukucutshungulwa futhi kusebenze ezinhlobonhlobo zemikhiqizo yepulasitiki, ukupakishwa kokudla, amabhokisi okudla okusheshayo, izindwangu ezingalukiwe, izindwangu zezimboni nezabantu, futhi umbono wemakethe othembisayo.
I-Biocompatibility
I-PLA iphinde ibe ne-biocompatibility enhle kakhulu, futhi umkhiqizo wayo wokuwohloka, i-L-lactic acid, ingabamba iqhaza kumetabolism yabantu.Igunyazwe i-US Food and Drug Administration (FDA) futhi ingasetshenziswa njengendlela yokuhlinza yezokwelapha, amaphilisi omjovo, ama-microspheres, kanye nezimila.
Ukuphefumula okuhle
Ifilimu ye-PLA inokuphefumula okuhle, i-oxygen permeability, kanye ne-carbon dioxide permeability, futhi inesici sokuhlukaniswa nephunga.Amagciwane kanye nesikhunta kulula ukunamathisela phezu kwamapulasitiki abolayo, ngakho-ke kukhona ukukhathazeka ngokuphepha nenhlanzeko.Kodwa-ke, i-PLA iyona kuphela ipulasitiki ebolayo enezinto ezinhle kakhulu zokulwa namagciwane kanye nesikhunta.
I-Biodegradability
I-PLA ingenye yezinto ezicwaningwe kakhulu ezibolayo ezibolayo eShayina naphesheya, futhi izindawo zayo ezintathu ezinkulu ezisetshenziswayo ezishisayo ukupakisha ukudla, izitsha zetafula ezilahlwayo, nezinto zokwelapha.
I-PLA, eyenziwe ngokuyinhloko nge-lactic acid yemvelo, inokubola okuhle kwe-biodegradability kanye ne-biocompatibility, futhi umjikelezo wayo wokuphila unomthelela ophansi kakhulu wemvelo kunezinto ezisekelwe ku-petroleum.Ibhekwa njengento ethembisa kakhulu yokupakisha eluhlaza ukuze ithuthukiswe.
Njengohlobo olusha lwezinto ezimsulwa zebhayoloji, i-PLA inamathuba amahle emakethe.Izakhiwo zayo ezinhle zomzimba kanye nobungane bemvelo ngokungangabazeki kuzokwenza i-PLA isetshenziswe kabanzi esikhathini esizayo.
