Zinthu zingapo zazikulu zomwe zimakhudza kusungidwa kwa madzi kwa hydroxypropyl methylcellulose
Hydroxypropyl methylcellulose (HPMC) ndi ether yosakhala ionic cellulose yopangidwa kuchokera ku cellulose yachilengedwe ya polima kudzera munjira zingapo zama mankhwala. Ndi ufa woyera wopanda fungo, wopanda poizoni komanso wopanda poizoni womwe umatuluka m'madzi ozizira kapena owoneka bwino. Lili ndi makulidwe, kumanga, kubalalika, emulsifying, kupanga mafilimu, kuyimitsa, kutsatsa, kutsekemera, kugwiritsira ntchito pamwamba, kusunga chinyezi komanso kuteteza colloid. Hydroxypropyl methyl cellulose ndi methyl cellulose angagwiritsidwe ntchito pomanga, mafakitale utoto, utomoni kupanga, makampani ceramic, mankhwala, chakudya, nsalu, ulimi, tsiku mankhwala ndi mafakitale ena.
Kusungidwa kwa madzi kwa mankhwala a hydroxypropyl methylcellulose HPMC pawokha kumakhudzidwa ndi izi:
1. Kuchuluka kwa hydroxypropyl methylcellulose HPMC kuwonjezeredwa Kuchuluka kwa cellulose ether HPMC kuwonjezeredwa, kukwezeka kwa madzi osungira madzi komanso kusunga madzi. Pakati pa 0.25-0.6% yowonjezera, kuchuluka kwa madzi osungira madzi kumawonjezeka mofulumira ndi kuwonjezeka kwa ndalama zowonjezera; pamene kuchuluka kwa madzi kumawonjezeka, kuwonjezeka kwa chiwerengero cha madzi osungira madzi kumachepa.
2. HPMC mamasukidwe akayendedwe a hydroxypropyl methylcellulose Pamene mamasukidwe akayendedwe a HPMC akuwonjezeka, kuchuluka kwa madzi osungirako kumawonjezekanso; pamene mamasukidwe akayendedwe akufika pamlingo wina, kuwonjezeka kwa madzi osungira madzi kumakhala kofatsa.
3. Hydroxypropyl methylcellulose HPMC kutentha kwa gel osakaniza Kutentha kwa gel osakaniza, kuchuluka kwa madzi osungira; mwinamwake, kutsika kwa madzi posungira mlingo.
4. Hydroxypropyl methylcellulose HPMC homogeneity HPMC ndi machitidwe ofanana, methoxyl ndi hydroxypropoxyl amagawidwa mofanana, ndipo mlingo wosungira madzi ndi wapamwamba.
