Iyini i-PDLLA Poly(DL-lactide) CAS 51056-13-9?

I-PDLLA iyi-polymer engaguquki enezinga lokushisa lokushintsha kwengilazi elingu-50-60℃ kanye nobubanzi be-viscosity obungu-0.2-7.0dl/g. Izinto ezisetshenziswayo zivunyelwe yi-FDA futhi zingasetshenziswa njengesithasiselo se-mucosa yokuhlinzwa yokulwa nokunamathela, ama-microcapsule, ama-microspheres kanye nama-implants ukuze kukhishwe isikhathi eside, futhi ingasetshenziswa njengezicabha ezinezimbobo zokuthuthukiswa kwamaseli obunjiniyela bezicubu kanye nokulungiswa kwamathambo noma izinto zokulungisa izicubu, njenge-sutures yokuhlinzwa, ama-implants, isikhumba sokwenziwa, imithambo yegazi yokwenziwa, kanye nama-retina amehlo.

Isicelo

‌1. I-cosmetology yezokwelapha‌: I-PDLLA isetshenziswa kabanzi njengesithako sokugcwalisa ubuso emkhakheni we-cosmetology yezokwelapha ngenxa yokuhambisana kwayo okuhle kakhulu kanye nokubola. Ingakhuthaza ukukhiqizwa kwe-collagen yesikhumba, ngaleyo ndlela ithuthukise ukugoba kwesikhumba, imibimbi kanye nokugoba.

‌2. Amadivayisi ezokwelapha‌: I-PDLLA isetshenziswa kabanzi emkhakheni wamadivayisi ezokwelapha, njengezembozo ezigcwele izidakamizwa ze-coronary stents ezibolayo, i-sutures yokuhlinzwa, ama-hemostatic clips, njll. Ukuhambisana kwayo okuhle kanye nokubola kwayo kwenza la madivayisi ezokwelapha aphephe futhi asebenze kangcono ngesikhathi sokusetshenziswa.

‌3. Ubunjiniyela bezicubu‌: I-PDLLA iphinde ibe nezinhlelo ezibalulekile emkhakheni wobunjiniyela bezicubu, njengokuqinisa amathambo nezinto zokulungisa amathambo, izisekelo zobunjiniyela bezicubu, njll. Isakhiwo sayo esinezimbobo siyasiza ekunamatheleni nasekukhuleni kwamaseli, ngaleyo ndlela sikhuthaze ukulungiswa nokuvuselelwa kwezicubu.

4. Ukukhishwa okulawulwa yimithi: I-PDLLA ingasetshenziswa futhi ekukhishweni okulawulwa yimithi kanye nokupakisha ukukhishwa okuqhubekayo. Ngokuyihlanganisa nemithi ukwenza amafomu omthamo njenge-microspheres noma ama-microcapsule, ukukhishwa kancane kanye nesenzo esiqhubekayo semithi kungafinyelelwa, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kanye nokuphepha kwemithi.

‌5. Ukusebenza kokubola kwe-PDLLA‌: I-PDLLA yonakala kancane kancane, okwenza ikwazi ukunikeza imiphumela yokwelapha ehlala isikhathi eside ekusetshenzisweni kwemitholampilo. Umkhiqizo wayo wokubola yi-lactic acid, ekugcineni eguqulwa ibe yi-carbon dioxide namanzi, futhi ayinabo ubuthi futhi ayinangozi emzimbeni womuntu‌
