PDLLA Poly(DL-lactide) CAS 51056-13-9
PDLLA ndi polima amorphous ndi galasi kusintha kutentha kwa 50-60 ℃ ndi kukhuthala osiyanasiyana 0.2-7.0dl/g. Zinthuzo zavomerezedwa ndi FDA ndipo zitha kugwiritsidwa ntchito ngati chothandizira pamankhwala oletsa zomatira mucosa, ma microcapsules, ma microspheres ndi ma implants kuti amasulidwe mosalekeza, komanso atha kugwiritsidwa ntchito ngati ma porous scaffolds a chikhalidwe cha cell engineering ndi kukonza mafupa kapena zida zokonzetsera minofu, monga ma sutures opangira opaleshoni, implants, ziwiya zamagazi zopanga komanso zopangira.

1. Medical cosmetology: PDLLA imagwiritsidwa ntchito kwambiri ngati chodzaza kumaso pantchito yazachipatala chifukwa cha kuyanjana kwake komanso kuwonongeka kwake. Itha kulimbikitsa kupanga kolajeni pakhungu, potero kumapangitsa kugwa kwa khungu, makwinya ndi kupsinjika.
2. Zipangizo zachipatala : PDLLA imagwiritsidwanso ntchito kwambiri pazida zamankhwala, monga zokutira zodzaza ndi mankhwala osokoneza bongo, ma sutures opangira opaleshoni, ma tapi a hemostatic, etc. Kugwirizana kwake kwabwino ndi kuwonongeka kumapangitsa kuti zipangizo zachipatalazi zikhale zotetezeka komanso zogwira ntchito panthawi yogwiritsira ntchito.
3. Umisiri wa minofu : PDLLA ilinso ndi ntchito zofunika kwambiri pankhani ya uinjiniya wa minofu, monga kukonza fupa ndi zida zokonza fupa, ma scaffolds opangira minofu, etc. Kapangidwe kake ka porous kumathandizira kulumikizana ndi kukula kwa maselo, potero kulimbikitsa kukonza minofu ndi kusinthika.
4 . Kutulutsa koyendetsedwa ndi mankhwala: PDLLA itha kugwiritsidwanso ntchito potulutsa mankhwala osokoneza bongo komanso kutulutsa kosalekeza. Pophatikiza ndi mankhwala kuti apange mawonekedwe a mlingo monga ma microspheres kapena ma microcapsules, kumasulidwa kwapang'onopang'ono ndi kukhazikika kwa mankhwala kungatheke, potero kumapangitsa mphamvu ndi chitetezo cha mankhwala.
5. Kuchita Zowonongeka kwa PDLLA: PDLLA imatsika pang'onopang'ono, zomwe zimapangitsa kuti izikhala ndi zotsatira zokhalitsa zochiritsira pazachipatala. Zomwe zimawonongeka ndi lactic acid, yomwe pamapeto pake imasinthidwa kukhala carbon dioxide ndi madzi, ndipo imakhala yopanda poizoni komanso yopanda vuto m'thupi la munthu.
