PDLLA Poly(DL-lactide) CAS 51056-13-9 ke eng?

PDLLA ke polymer ea amorphous e nang le mocheso oa khalase oa 50-60 ℃ le mefuta e mengata ea viscosity ea 0.2-7.0dl/g. Thepa e amohetsoe ke FDA mme e ka sebelisoa e le mothusi bakeng sa mucosa ea bongaka e thibelang likhomaretsi, li-microcapsules, li-microspheres le li-implants bakeng sa tokollo e tsitsitseng, hape e ka sebelisoa e le li-scaffolds tsa porous bakeng sa setso sa lisele tsa lisele le ho lokisa masapo kapa lisebelisoa tsa ho lokisa lisele, joalo ka sutures ea opereishene, li-implants, letlalo la maiketsetso le letlalo la maiketsetso.

Kopo

1. Cosmetology ea bongaka: PDLLA e sebelisoa haholo joalo ka setlolo sa sefahleho lefapheng la cosmetology ea bongaka ka lebaka la ts'ebeliso e ntle ea biocompatibility le ho senyeha ha eona. E ka susumetsa tlhahiso ea collagen ea letlalo, kahoo e ntlafatsa ho sisinyeha ha letlalo, wrinkles le depressions.

2. Lisebelisoa tsa meriana : PDLLA e boetse e sebelisoa haholo lefapheng la lisebelisoa tsa bongaka, tse kang liphahlo tse tletseng lithethefatsi bakeng sa li-coronary stents tse senyehang, li-sutures tsa ho buuoa, li-hemostatic clips, joalo-joalo. Biocompatibility ea eona e ntle le ho senyeha ha eona ho etsa hore lisebelisoa tsena tsa bongaka li sireletsehe le ho atleha haholoanyane nakong ea tšebeliso.

3. Boenjiniere ba masela: PDLLA e boetse e na le lisebelisoa tsa bohlokoa lefapheng la boenjiniere ba lisele, tse kang ho lokisa masapo le lisebelisoa tsa ho lokisa masapo, li-scaffolds tsa boenjiniere ba lisele, joalo-joalo.

4. Tokollo e laoloang ke lithethefatsi: PDLLA e ka boela ea sebelisoa bakeng sa tokollo e laoloang ke lithethefatsi le ho paka ka nako e telele. Ka ho e kopanya le lithethefatsi ho etsa mefuta ea litekanyetso tse kang microspheres kapa microcapsules, ho lokolloa butle-butle le ketso e tsitsitseng ea lithethefatsi e ka finyelloa, kahoo ho ntlafatsa katleho le polokeho ea lithethefatsi.

5. Ts'ebetso ea ho nyenyefatsa ea PDLLA: PDLLA e fokotseha butle butle, e leng se e nolofalletsang ho fana ka litlamorao tsa nako e telele tsa kalafo lits'ebetsong tsa bongaka. Sehlahisoa sa eona se senyehang ke lactic acid, e qetellang e kenngoa ka har'a carbon dioxide le metsi, 'me ha e chefo ebile ha e kotsi' meleng oa motho.
