Imithombo yezinto ezikrwada ezininzi
Izinto ezisetyenziselwa ukuvelisa i-polylactic acid (PLA) zivela kwimithombo ehlaziyiweyo efana nombona, ngaphandle kwesidingo sezinto ezixabisekileyo zendalo ezifana ne-petroleum okanye imithi, ngaloo ndlela inceda ukukhusela i-oyile eyanciphayo.
Iimpawu eziphezulu zomzimba
I-PLA ilungele iindlela ezahlukeneyo zokusetyenzwa ezinje ngokubumba ukuvuthela kunye ne-thermoplastics, iyenza kube lula ukusetyenzwa kwaye isebenze kuluhlu olubanzi lweemveliso zeplastiki, ukupakishwa kokutya, iibhokisi zokutya okukhawulezayo, amalaphu angalukwanga, amalaphu emizi-mveliso kunye nabahlali, kwaye inesixhobo esikhulu. imbonakalo yemarike ethembisayo.
Biocompatibility
I-PLA nayo ine-biocompatibility egqwesileyo, kunye nemveliso yayo yokuthotywa, i-L-lactic acid, inokuthatha inxaxheba kwi-metabolism yabantu. Ivunyiwe yi-US Food and Drug Administration (FDA) kwaye inokusetyenziswa njenge-suture yonyango yokuhlinzwa, ii-capsules ezitofwayo, i-microspheres, kunye nokufakelwa.
Ukuphefumla kakuhle
Ifilimu ye-PLA inokuphefumla kakuhle, i-oxygen permeability, kunye ne-carbon dioxide permeability, kwaye inophawu lokuzihlukanisa nevumba. Iintsholongwane kunye nokungunda kulula ukuncamathisela kumphezulu weeplastiki ze-biodegradable, ngoko kukho iinkxalabo zokhuseleko kunye nococeko. Nangona kunjalo, i-PLA kuphela kweplastiki enokubola kunye neempawu ezibalaseleyo zokulwa ne-antibacterial kunye ne-anti-mold.
I-Biodegradability
I-PLA yenye yezona zinto ziphandiweyo ze-biodegradable e-China nakwamanye amazwe, kwaye iindawo zayo ezintathu eziphambili zezicelo ezishushu kukupakishwa kokutya, i-tableware elahlayo, kunye nezixhobo zonyango.
I-PLA, eyenziwe ngokukodwa kwi-asidi ye-lactic yendalo, inokonakala okuhle kwe-biodegradability kunye ne-biocompatibility, kwaye umjikelo wayo wobomi unempembelelo ephantsi kakhulu yokusingqongileyo kunezinto ezisekelwe kwi-petroleum. Ithathwa njengeyona nto ithembisayo yokupakisha eluhlaza kuphuhliso.
Njengodidi olutsha lwezinto ezicocekileyo zebhayoloji, i-PLA inamathuba amahle emarike. Iimpawu zayo ezintle zomzimba kunye nobuhlobo bendalo ngokungathandabuzekiyo ziya kwenza i-PLA isetyenziswe ngokubanzi kwixesha elizayo.
