Akawanda mbishi zvinyorwa
Iyo mbishi inoshandiswa kugadzira polylactic asidhi (PLA) inobva kune zvinogonekazve sechibage, pasina kudiwa kwezviwanikwa zvakakosha sepetroleum kana huni, zvichibatsira kuchengetedza zviwanikwa zveoiri zviri kuderera.
Superior physical properties
PLA inokodzera nzira dzakasiyana dzekugadzirisa senge blow molding uye thermoplastics, zvichiita kuti zvive nyore kugadzirisa uye kushanda kune dzakasiyana siyana zvigadzirwa zvepurasitiki, kurongedza chikafu, mabhokisi echikafu nekukurumidza, machira asiri akarukwa, machira emuindasitiri neasinga rume, uye ane machira akanyanya. anovimbisa musika maonero.
Biocompatibility
PLA zvakare ine yakanakisa biocompatibility, uye yayo yekushatisa chigadzirwa, L-lactic acid, inogona kutora chikamu mumetabolism yevanhu. Yakatenderwa neUS Food and Drug Administration (FDA) uye inogona kushandiswa seyekurapa yekuvhiya suture, injectable capsules, microspheres, uye implants.
Kufema kwakanaka
Firimu rePLA rine kufema kwakanaka, oxygen permeability, uye carbon dioxide permeability, uye inewo hunhu hwekunhuhwirira wega. Mavhairasi uye mold zviri nyore kubatika pamusoro peiyo biodegradable mapurasitiki, saka pane kuchengetedza uye hutsanana zvinonetsa. Nekudaro, PLA ndiyo yega biodegradable plastiki ine yakanakisa antibacterial uye anti-mold zvivakwa.
Biodegradability
PLA ndechimwe chezvakanyanya kutsvagirwa biodegradable zvinhu muChina nekune dzimwe nyika, uye nzvimbo dzayo nhatu huru dzinopisa dzekushandisa kurongedza chikafu, zvinoraswa tableware, uye zvekurapa.
PLA, iyo inonyanya kugadzirwa kubva pachisikigo lactic acid, ine yakanaka biodegradability uye biocompatibility, uye kutenderera kwehupenyu hwayo kune kuderera zvakanyanya kwezvakatipoteredza pane petroleum-based zvinhu. Inoonekwa seyakasvibirira yekurongedza zvinhu zvekusimudzira.
Serudzi rutsva rwezvinhu zvakachena zvipenyu, PLA ine tarisiro huru yemusika. Hunhu hwayo hwakanaka hwemuviri uye hushamwari hwezvakatipoteredza pasina mubvunzo huchaita kuti PLA iwedzere kushandiswa mune ramangwana.
