PDLLA Poly(DL-lactide) CAS 51056-13-9
PDLLA iamorphous polymer ine tembiricha yegirazi ye50-60 ℃ uye viscosity range ye 0.2-7.0dl/g. Izvo zvinhu zvakatenderwa neFDA uye zvinogona kushandiswa seadjuvant yekurapa yekuvhiya anti-adhesive mucosa, microcapsules, microspheres uye implants kuti irambe ichiburitswa, uye inogona zvakare kushandiswa senge porous scaffolds yetishu engineering cell tsika uye kugadzirisa bhonzo kana matishu ekugadzirisa zvinhu, sekuvhiya sutures, implants, artificial reropa midziyo yeropa.

1. Medical cosmetology: PDLLA inoshandiswa zvakanyanya sekuzadza kumeso mumunda wezvekurapa cosmetology nekuda kwekunaka kwayo biocompatibility uye kuderera. Inogona kukurudzira kugadzirwa kweganda collagen, nokudaro kuvandudza ganda sagging, wrinkles uye depressions.
2. Zvishandiso zvekurapa : PDLLA inoshandiswawo zvakanyanya mundima yezvigadzirwa zvekurapa, senge zvinodhaka-zvakaremerwa mabhanhire ezvinotapukira coronary stents, sutures sutures, hemostatic clips, etc. Iyo yakanaka biocompatibility uye kuparara kunoita kuti michina iyi yekurapa ive yakachengeteka uye inoshanda zvakanyanya panguva yekushandiswa.
3. Tissue engineering : PDLLA inewo maapplication akakosha mumunda weinjiniya yetishu, sekugadzirisa bhonzo uye mapfupa ekugadzirisa zvinhu, tishu engineering scaffolds, etc. Yayo porous chimiro inoenderana nekubatanidzwa uye kukura kwemaseru, nekudaro ichikurudzira kugadziriswa kwetishu uye kuvandudzwa.
4. Mushonga unodzorwa kuburitswa: PDLLA inogona zvakare kushandiswa kuburitsa inodzorwa zvinodhaka uye inosimudzira kuburitsa kurongedza. Nekuisanganisa nemishonga kuita mafomu ekuyeresa akadai semamicrospheres kana microcapsules, kuburitswa kunononoka uye kuita kwakasimba kwemishonga kunogona kuwanikwa, nekudaro kuvandudza kushanda uye kuchengetedzwa kwezvinodhaka.
5. Kushatisa kuita kwePDLLA: PDLLA inodzikisira zvishoma nezvishoma, izvo zvinoita kuti ipe mhedzisiro yenguva refu yekurapa mumakiriniki ekushandisa. Chigadzirwa chayo chekusvibisa ilactic acid, iyo inozopedzisira yagadziriswa kuita kabhoni dhaikisaidhi nemvura, uye haina chepfu uye haina kukuvadza kumuviri wemunhu.
