Katundu wa hpmc (hydroxypropyl methyl cellulose)

Hydroxypropyl methylcellulose (hpmc) ndi polymer polder ochokera ku cellulose. Ili ndi zinthu zingapo zomwe zimapangitsa kuti zizithandiza pamagulu osiyanasiyana. Nazi katundu wa HPMC:

1. Madzi osungunuka: hpmc amasungunuka m'madzi ozizira, ndikupanga zomveka, ma viscous. Miyezo yosungunuka imasiyanasiyana malinga ndi kuchuluka kwa zolowa m'malo mwazolowa (DS) ndi kutukwana kwa polymer ya polymer.
2. Kukhazikika kwamafuta: HPMC imawonetsa kukhazikika kwamitundu yabwino, kusunganso katundu wake pamtunda wotentha. Itha kupirira makonzedwe omwe anakumana nawo kumayiko osiyanasiyana, kuphatikizapo mapulogalamu ophatikizidwa ndi zomangamanga.
3. Mapangidwe a filimu: HPMC ili ndi katundu wopanga mafilimu, omwe amalola kuti apange mafilimu omveka bwino ndikuwuma. Katunduyu ndi wopindulitsa mu zokutira za mankhwala, komwe Hpmc imagwiritsidwa ntchito mapiritsi ndi makapisozi kuti alamuledwe mankhwala.
4. Kutha Kukula: HPMC imagwira ngati wothandizila mu mayankho am'madzi, kuwonjezera mamasukidwe ndikusintha kapangidwe ka kapangidwe kake. Nthawi zambiri amagwiritsidwa ntchito pa zotupa, zomata, zodzola, ndi zakudya zothandizira zomwe zikufuna.
5. Kusintha kwa Rhelogy: HPMC imakhala ngati Rhelogy yosintha, imapangitsa kuti mayendedwe ndi mafayilo azotheka. Imawonetsa machitidwe a pseudoplactic, kutanthauza kuti ma viscy ake amachepa pansi pa kupsinjika kukameta ubweya, kulola kugwiritsa ntchito mosavuta.
6. Kusunga kwamadzi: HPMC ili ndi madzi ambiri osunga madzi, kuthandiza kupewa kunyowa mu mawonekedwe. Katunduyu ndi wofunika kwambiri popanga zomanga monga mankhusu ndi kubwereketsa, komwe hpmc amathandizira kugwirira ntchito komanso kutsatira.
7. Kukhazikika kwa mankhwala: HPMC imakhazikika munthawi ya Ph, ndikupanga kukhala koyenera kugwiritsa ntchito mapangidwe osiyanasiyana. Ikugwirizana ndi kuwonongeka kwa microbial ndipo sikugwirizana ndi zosintha zamankhwala zomwe zimasungidwa bwino.
8. Kugwirizana: HPMC imagwirizana ndi zinthu zina zambiri, kuphatikizapo ma polima, oundana, ndi zowonjezera. Itha kuphatikizidwa mosavuta kukhala kapangidwe kake popanda kuyambitsa mavuto kapena kusokoneza magwiridwe antchito ena.
9. Zachilengedwe: hpmc ndi polymer yopanda tanthauzo, kutanthauza kuti sizinyamula ndalama zamagetsi poyankha. Katunduyu amathandizira pakusintha kwake komanso kuphatikizidwa ndi mitundu yosiyanasiyana ya mapangidwe ndi zosakaniza.

Hydroxypypyl methylcellulose (hpmc) amakhala ndi kuphatikiza kwapadera kwa zinthu zomwe zimapangitsa kukhala kofunikira kwambiri m'mafakitale osiyanasiyana. Kusungunuka kwake, kukhazikika kwake, kuthekera kwamafilimu, kusinthika kwa mafilimu, kusungunuka kwamadzi, kukhazikika kwamadzi, komanso kusiyanasiyana kwa zinthu zina zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito zosiyanasiyana.
