Kodi hypromellose ndi yachilengedwe?

Hypromellose, yomwe imadziwikanso kuti hydroxypropyl methylcellulose (HPMC), ndi polima yopangidwa kuchokera ku cellulose, polima yachilengedwe yomwe imapezeka m'makoma a maselo a zomera. Ngakhale kuti cellulose yokha ndi yachilengedwe, njira yosinthira kuti ipange hypromellose imaphatikizapo zochita za mankhwala, zomwe zimapangitsa hypromellose kukhala mankhwala opangidwa kuchokera ku semisynthetic.

Kupanga hypromellose kumaphatikizapo kuchiza cellulose ndi propylene oxide ndi methyl chloride kuti ipangitse magulu a hydroxypropyl ndi methyl ku msana wa cellulose. Kusintha kumeneku kumasintha mawonekedwe a cellulose, zomwe zimapangitsa hypromellose kukhala ndi makhalidwe ake apadera monga kusungunuka kwa madzi, mphamvu yopanga filimu, komanso kukhuthala.

Ngakhale kuti hypromellose siipezeka mwachindunji m'chilengedwe, imachokera ku gwero lachilengedwe (cellulose) ndipo imaonedwa kuti imagwirizana ndi zamoyo komanso imatha kuwonongeka. Imagwiritsidwa ntchito kwambiri mu mankhwala, zakudya, zodzoladzola, ndi ntchito zosiyanasiyana zamafakitale chifukwa cha chitetezo chake, kusinthasintha kwake, komanso magwiridwe antchito ake.

Mwachidule, ngakhale kuti hypromellose ndi mankhwala opangidwa pang'onopang'ono, chiyambi chake kuchokera ku cellulose, polima wachilengedwe, komanso kuyanjana kwake ndi zinthu zina zimapangitsa kuti ikhale chinthu chovomerezeka kwambiri m'magwiritsidwe osiyanasiyana.
