Kodi hypromellose imapangidwa kuchokera ku chiyani?

Hypromellose, yomwe imadziwikanso kuti hydroxypropyl methylcellulose (HPMC), ndi polima semisynthetic yochokera ku cellulose, yomwe ndi polima yopezeka mwachilengedwe yomwe imapezeka m'makoma a zomera. Umu ndi momwe hypromellose imapangidwira:

1. Ma cellulose Sourcing: Njirayi imayamba ndikuchotsa cellulose, yomwe imapezeka kuchokera kumitengo yosiyanasiyana monga zamkati zamatabwa, ulusi wa thonje, kapena zomera zina za ulusi. Ma cellulose nthawi zambiri amatengedwa kuchokera kuzinthu izi kudzera muzinthu zingapo zamakina ndi makina kuti apeze zinthu zoyeretsedwa za cellulose.
2. Etherification: Ma cellulose oyeretsedwa amakumana ndi njira yosinthira mankhwala yotchedwa etherification, pomwe magulu a hydroxypropyl ndi methyl amalowetsedwa pamsana wa cellulose. Kusintha uku kumatheka ndikuchitapo kanthu pa cellulose ndi propylene oxide (kuyambitsa magulu a hydroxypropyl) ndi methyl chloride (kuyambitsa magulu a methyl) molamulidwa.
3. Kuyeretsedwa ndi Kukonza: Pambuyo pa etherification, mankhwala omwe amachokerawo amayeretsedwa kuti achotse zonyansa ndi zotsalira zomwe zimachitika. Hypromellose yoyeretsedwa imasinthidwa kukhala mitundu yosiyanasiyana monga ufa, ma granules, kapena mayankho, kutengera momwe akufunira.
4. Kuwongolera Ubwino: Panthawi yonse yopanga, njira zowongolera zabwino zimayendetsedwa kuti zitsimikizire kuyera, kusasinthika, komanso magwiridwe antchito a hypromellose. Izi zikuphatikiza kuyesa magawo monga kulemera kwa mamolekyu, kukhuthala, kusungunuka, ndi zina zakuthupi ndi zamankhwala.
5. Kupaka ndi Kugawa: Chogulitsa cha hypromellose chikakwaniritsa zofunikira, chimayikidwa muzotengera zoyenera ndikugawidwa ku mafakitale osiyanasiyana kuti agwiritsidwe ntchito pazamankhwala, zakudya, zodzoladzola, ndi ntchito zina.

Ponseponse, hypromellose imapangidwa kudzera munjira zingapo zoyendetsedwa ndi mankhwala komanso njira zoyeretsera zomwe zimagwiritsidwa ntchito pa cellulose, zomwe zimapangitsa kuti pakhale polima wosunthika komanso wogwiritsidwa ntchito mosiyanasiyana wogwiritsa ntchito mosiyanasiyana m'mafakitale osiyanasiyana.
