Puas yog hypromellose ntuj?

Hypromellose, tseem hu ua HydroxyPropyyl methylcelulose (HPMC), yog semisynthetic polymer muab tau los ntawm cellulose, lub ntuj polymer pom nyob hauv cov phab ntsa ntawm tes ntawm cov nroj tsuag. Thaum lub cellulose nws tus kheej yog ntuj, txheej txheem ntawm kev hloov kho nws los tsim cov tshuaj hypromellose muaj cov tshuaj lom neeg cov tshuaj lom neeg.

Kev tsim khoom ntawm hypromellose cuam tshuam nrog cov cellulose nrog cov tshuaj pleev cov epylene oxide thiab methyl cermeside los qhia hydroxypropyl thiab methyl pawg mus rau lub cellulose cellebone. Qhov kev hloov kho tshiab ntawm cov khoom ntawm cellulose, muab Hypromellose nws cov yam ntxwv tshwj xeeb xws li cov dej solubility, ua yeeb yaj kiab ua yeeb yam, thiab viscosity.

Thaum hypromellose tsis pom ncaj qha nyob rau hauv xwm, nws yog muab tau los ntawm lub ntuj ntuj (cellulose) thiab yog suav hais tias biocompadable thiab biodegradable thiab biodegradable. Nws yog dav siv hauv cov tshuaj, khoom noj khoom haus, tshuaj pleev ib ce, thiab ntau daim ntawv thov kev muaj kev muaj kev nyab xeeb vim nws kev nyab xeeb, versatility, thiab kev ua haujlwm.

Hauv cov ntsiab lus xaus, thaum hypromellose yog semisynthetic compound, nws lub hauv paus chiv keeb los ntawm cellulose, thiab nws biocompatibility ua nws dav tau txais cov khoom siv tau txais nyob rau hauv ntau yam kev siv.
