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

I-PDLLA i-polymer e-amorphous ene-glass transition yeqondo lokushisa kwe-50-60 ℃ kunye ne-viscosity range ye-0.2-7.0dl / g. Izinto eziphathekayo zivunyiwe yi-FDA kwaye zinokusetyenziswa njenge-adjuvant ye-anti-adhesive mucosa yonyango, i-microcapsules, i-microspheres kunye nokufakelwa ukukhutshwa okuqhubekayo, kwaye inokusetyenziswa njenge-scaffolds e-porous yenkcubeko yobunjineli beeseli kunye nokulungiswa kwamathambo okanye izinto zokulungisa izicubu, ezifana ne-sutures yotyando, implants, i-artificial artificial imikhumbi yegazi lokwenziwa.

Isicelo

1. I-cosmetology yezoNyango: I-PDLLA isetyenziswa ngokubanzi njengesizaliso sobuso kwicandelo le-cosmetology yonyango ngenxa yokuhambelana kwayo okugqwesileyo kunye nokonakala. Inokukhuthaza ukuveliswa kwe-collagen yesikhumba, ngaloo ndlela iphucula ukucwina kwesikhumba, imibimbi kunye nokudandatheka.

2. Izixhobo zonyango : I-PDLLA isetyenziswa ngokubanzi kwinkalo yezixhobo zonyango, ezifana neengubo ezilayishwe ngamachiza e-coronary stents, i-sutures sutures, i-hemostatic clips, njl.

3. Ubunjineli bezicubu: I-PDLLA nayo inezicelo ezibalulekileyo kwintsimi yobunjineli bezicubu, ezifana nokulungiswa kwamathambo kunye nezixhobo zokulungisa amathambo, i-scaffolds yobunjineli bezicubu, njl.

4. Ukukhutshwa okulawulwa kweziyobisi: I-PDLLA inokusetyenziselwa ukukhutshwa okulawulwayo kweziyobisi kunye nokupakishwa kokukhululwa okuqhubekayo. Ngokudibanisa kunye neziyobisi ukwenza iifom zedosi ezifana ne-microspheres okanye i-microcapsules, ukukhululwa okucothayo kunye nesenzo esiqhubekayo samachiza sinokufezekiswa, ngaloo ndlela kuphuculwe ukusebenza kunye nokhuseleko lwamachiza.

5. Ukusebenza kokuthotywa kwePDLLA: I-PDLLA ithotywa kancinci, nto leyo eyenza ukuba ibonelele ngeziphumo zonyango ezihlala ixesha elide kwizicelo zeklinikhi. Imveliso yayo yokuthotywa yi-lactic acid, ethi ekugqibeleni ifakwe kwi-carbon dioxide namanzi, kwaye ayinayo ityhefu kwaye ayinabungozi emzimbeni womntu.
