Yintoni iPDLLA Poly(DL-lactide) CAS 51056-13-9?

I-PDLLA yi-polymer engenasimo esifana neglasi enobushushu bokutshintsha kweglasi obuyi-50-60℃ kunye nobubanzi be-viscosity obuyi-0.2-7.0dl/g. Le nto ivunyiwe yi-FDA kwaye ingasetyenziswa njenge-adjuvant kwi-mucosa yotyando lwezonyango oluchasene nokunamathela, ii-microcapsules, ii-microspheres kunye nee-implants ukuze zikhutshwe rhoqo, kwaye zingasetyenziswa njenge-scaffolds ezinemingxuma yobunjineli bezicubu kunye nokulungiswa kwamathambo okanye izixhobo zokulungisa izicubu, ezifana nee-sutures zotyando, ii-implants, ulusu lokwenziwa, imithambo yegazi yokwenziwa, kunye nee-retinas zamehlo.

Isicelo

‌1. I-cosmetology yezonyango‌: I-PDLLA isetyenziswa kakhulu njengesithambisi sobuso kwicandelo le-cosmetology yezonyango ngenxa yokuba ihambelana kakuhle ne-biocompatibility kunye nokubola kwayo. Ingakhuthaza ukuveliswa kwe-collagen yesikhumba, ngaloo ndlela iphucula ukugoba kwesikhumba, imibimbi kunye nokuxinana.

2. Izixhobo zonyango: I-PDLLA ikwasetyenziswa kakhulu kwicandelo lezixhobo zonyango, ezifana neengubo ezifakwe amayeza kwii-coronary stents ezibolayo, ii-sutures zotyando, ii-hemostatic clips, njl. Ukuhambelana kwayo kakuhle kunye nokubola kwayo kwenza ezi zixhobo zonyango zikhuseleke kwaye zisebenze ngakumbi xa zisetyenziswa.

‌3. Ubunjineli bezicubu: I-PDLLA ikwanokusetyenziswa okubalulekileyo kwicandelo lobunjineli bezicubu, njengokulungisa amathambo kunye nezixhobo zokulungisa amathambo, izikhonkwane zobunjineli bezicubu, njl. Ulwakhiwo lwayo olunemingxuma lunceda ekunamatheleni nasekukhuleni kweeseli, ngaloo ndlela lukhuthaza ukulungiswa nokuhlaziywa kwezicubu.

4. Ukukhululwa okulawulwa ngamayeza: I-PDLLA ingasetyenziselwa ukukhululwa okulawulwa ngamayeza kunye nokupakisha ukukhululwa okuqhubekayo. Ngokuyidibanisa namayeza ukwenza iifom zedosi ezifana nee-microspheres okanye ii-microcapsules, ukukhululwa kancinci kunye nesenzo esiqhubekayo samayeza kunokufezekiswa, ngaloo ndlela kuphuculwe ukusebenza kakuhle kunye nokhuseleko lwamayeza.

‌5. Ukusebenza kokubola kwe-PDLLA‌: I-PDLLA ibola kancinci kancinci, nto leyo eyenza ukuba ikwazi ukubonelela ngemiphumo yonyango ehlala ixesha elide kwizicelo zonyango. Imveliso yayo yokubola yi-lactic acid, ekugqibeleni iguqulwa ibe yi-carbon dioxide namanzi, kwaye ayinabungozi kwaye ayinabungozi emzimbeni womntu‌
