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

I-PDLLA i-amorphous polymer enezinga lokushisa lengilazi elishintshayo elingu-50-60℃ kanye nebanga le-viscosity elingu-0.2-7.0dl/g. Izinto ezisetshenziswayo zigunyazwe yi-FDA futhi zingasetshenziswa njenge-adjuvant ye-anti-adhesive mucosa yezokwelapha, ama-microcapsules, ama-microsphere kanye nokufakwa ukuze kukhululwe okuqhubekayo, futhi ingasetshenziswa njengezikafula ezimbotshana zesiko lobunjiniyela bezicubu kanye nokulungiswa kwamathambo noma izinto zokulungisa izicubu, njengokuhlinza, izimila, izitsha zegazi lokufakelwa, isikhumba sokwenziwa.

Ukucaciswa

Isicelo

1. I-cosmetology yezokwelapha: I-PDLLA isetshenziswa kabanzi njengesigcwalisi sobuso emkhakheni we-cosmetology yezokwelapha ngenxa ye-biocompatibility yayo enhle kakhulu kanye nokonakala. Ingashukumisa ukukhiqizwa kwe-collagen yesikhumba, ngaleyo ndlela ithuthukise ukuwohloka kwesikhumba, imibimbi kanye nokucindezeleka.

2. Izinsiza zezokwelapha

3. Ubunjiniyela bezicubu ze-tissue

4. Ukukhishwa okulawulwa yizidakamizwa: I-PDLLA ingaphinda isetshenziselwe ukukhululwa okulawulwa yizidakamizwa kanye nokupakishwa kokukhululwa okuqhubekayo. Ngokuyihlanganisa nezidakamizwa ukwenza amafomu omthamo njengama-microspheres noma ama-microcapsules, ukukhululwa kancane kanye nesenzo esiqhubekayo sezidakamizwa kungafinyelelwa, ngaleyo ndlela kuthuthukiswe ukusebenza kahle nokuphepha kwezidakamizwa.

5. Ukusebenza kokuwohloka kwe-PDLLA: I-PDLLA yehla kancane uma kuqhathaniswa, okuyenza ikwazi ukuhlinzeka ngemiphumela yokwelapha ehlala isikhathi eside ezinhlelweni zomtholampilo. Umkhiqizo wawo wokuwohloka yi-lactic acid, egcina igaywe ibe yi-carbon dioxide namanzi, futhi ayinabo ubuthi futhi ayinabungozi emzimbeni womuntu.
