Iyini i-Polylactic Acid PLA CAS 26100-51-6?

I-Poly (i-lactic acid), eyaziwa nangokuthi i-polylactide, iwuhlobo olusha lwezinto ezibolayo ezitholwe ngokwenza i-polymerization ye-lactic acid njengento eluhlaza eyinhloko. Ine-biodegradability enhle futhi ingacekelwa phansi ngokuphelele ama-microorganisms emvelweni ngemva kokusetshenziswa, ekugcineni ikhiqize isikhutha namanzi ngaphandle kokungcolisa imvelo. Lokhu kuzuzisa kakhulu ekuvikelweni kwemvelo futhi kuqashelwa njengento ehambisana nemvelo. I-PLA inezinhlelo zokusebenza eziningi, okuhlanganisa i-extrusion, ukubumba umjovo, ukudonsa ifilimu, ukuphotha, nezinye izinkambu.

Isicelo

I-Polylactic acid (PLA) yethulwa ngo-1966 ukuze kufakwe izimila zokuhlinzwa eziwohlokayo. I-Hydrolysis ikhiqiza i-lactic acid, indawo evamile emaphakathi ye-carbohydrate metabolism. I-Polyglycolic acid sutures inezinga lokuwohloka elibikezelwayo elihambisana nokulandelana kokuphulukisa kwezicubu zemvelo.I-PLA inezinhlelo zokusebenza eziningi, ezihlanganisa i-extrusion, ukubumba umjovo, ukudonsa ifilimu, ukuphotha, neminye imikhakha.
