Codsiga

Soo saarista lactic acid ee alaabta ceeriin waxay inta badan ku saleysan tahay isticmaalka uumiga lactic acid si loo soo saaro oligomers lactic acid, ka dibna oligomers lactic acid waa la depolymerized iyo baaskiil si ay u soo saaraan lactide.Geedi socodka oo dhan wuxuu u baahan yahay in lagu fuliyo xaaladaha heerkulka sare, cadaadiska xun iyo catalysis.Inta lagu jiro habka, si loo hagaajiyo wax-soo-saarka guud, aan falcelin lahayn waa in dib loo isticmaalo reflux.Ugu dambeyntii, alaabooyinka lactide-ka ah ee u qalma waxaa lagu heli karaa siyaabo sifeyn gaar ah.
Maaddaama ay tahay walxo biodegradable ah, waxaa inta badan loo isticmaalaa hagaajinta taarikada, tolida qalliinka, stent-ka wadnaha, iyo buuxinta jirka.
