Momwe mungasulire hydroxypropyl methylcellulose (hpmc)

Hydroxypylferose (HPMC) imagwiritsidwa ntchito kwambiri pomanga, zofukizira, matekenti, zamankhwala, zamalonda, fodya komanso mafakitale ena. Hydroxypropyl me cellulose (hpmc) ndi ma cellulose osaya a ether ether exul exul eyal eyather eyather ether eyather eyather eyather eyather eyather eyather eyather eyather eyather eyather eyather eyather eyal adapeza kuchokera ku cellulose yachilengedwe ya polymer kudzera munthawi yamankhwala angapo. Hydroxypypyl methylcellulose (hpmc) ndi ufa wopanda mafuta, wopanda ufa woyera womwe ungasungunuke m'madzi ozizira kuti apange yankho lowonekera. Ili ndi katundu wa kuthira, kumanga, kubalalitsa, emulsifteming, kupanga mafilimu, kuyimitsa, kudzipatula, kusunganso chinyezi ndi kuteteza ma colodi.
Njira Yokhumudwitsa ya Hydroxypropyl Methylcellulose (HPMC):
Izi zimatupa ndikubalalitsa m'madzi otentha pamwamba pa 85 ° C, ndipo nthawi zambiri amasungunuka ndi njira zotsatirazi:
1. Tengani 1/3 ya madzi otentha a madzi otentha, kwezani kuti asungunuke kwathunthu, kenako ndikuwonjezera madzi okwanira kapena madzi oundana (20 ℃), imatha kusungunuka kwathunthu.
2. Zophatikiza zowuma:
Pankhani yosakanikirana ndi ufa wina, ziyenera kusakanizidwa bwino ndi ufawo ndikuwonjezera ndi madzi, kuti asungunuke mwachangu ndipo sangasinthe.
3. Njira yosungunuka yonyowa:
Choyamba kufalitsa mankhwalawo mu zosungunulira kapena kunyowa ndi zosungunulira, kenako ndikuwonjezera madzi ozizira, zitha kusungunuka bwino.
