Puas yog hypromellose ntuj?

Hypromellose, tseem hu ua hydroxypropyl methylcellulose (HPMC), yog ib tug semisynthetic polymer muab los ntawm cellulose, ib tug natural polymer pom nyob rau hauv lub cell phab ntsa ntawm cov nroj tsuag. Thaum cellulose nws tus kheej yog ntuj, cov txheej txheem ntawm kev hloov kho nws los tsim hypromellose cuam tshuam cov tshuaj tiv thaiv, ua hypromellose ib semisynthetic compound.

Kev tsim cov hypromellose suav nrog kev kho cellulose nrog propylene oxide thiab methyl chloride los qhia hydroxypropyl thiab methyl pawg mus rau cov pob txha cellulose. Qhov kev hloov pauv no hloov cov khoom ntawm cellulose, muab hypromellose nws cov yam ntxwv tshwj xeeb xws li dej solubility, muaj peev xwm ua yeeb yaj kiab, thiab viscosity.

Thaum hypromellose tsis pom ncaj qha rau hauv cov xwm txheej, nws tau muab los ntawm lub ntuj tsim (cellulose) thiab suav tias yog biocompatible thiab biodegradable. Nws yog dav siv nyob rau hauv kws tshuaj, khoom noj khoom haus, tshuaj pleev ib ce, thiab ntau yam kev lag luam daim ntawv thov vim nws kev nyab xeeb, versatility, thiab functionality.

Nyob rau hauv cov ntsiab lus, thaum hypromellose yog ib tug semisynthetic compound, nws keeb kwm los ntawm cellulose, ib tug natural polymer, thiab nws biocompatibility ua rau nws ib tug dav txais cov khoom nyob rau hauv ntau yam kev siv.
