Daim ntawv thov

Kev tsim cov lactide los ntawm lactic acid raw khoom yog tsim los ntawm kev siv cov lactic acid condensation los tsim cov lactic acid oligomers, thiab tom qab ntawd cov lactic acid oligomers yog depolymerized thiab cyclized los tsim lactide. Tag nrho cov txheej txheem yuav tsum tau ua nyob rau hauv cov kev mob ntawm kub siab, tsis zoo siab thiab catalysis. Thaum lub sij hawm tus txheej txheem, txhawm rau txhim kho tag nrho cov txiaj ntsig, cov khoom tsis zoo yuav tsum tau rov qab siv los ntawm reflux. Thaum kawg, cov khoom tsim nyog lactide tuaj yeem tau txais los ntawm kev ua kom huv si.
Raws li cov khoom siv biodegradable, nws yog tsuas yog siv rau kho daim hlau, phais sutures, lub plawv stents, thiab lub cev muab tub lim.
