Hydroxypropyl methylcellulose (hpmc)ndi malo opangidwa ndi madzi osungunuka osungunuka chifukwa cha cellulose yachilengedwe kudzera mu kusintha mankhwala. Amagwiritsidwa ntchito kwambiri mu mankhwala, zodzikongoletsera, chakudya, zomanga ndi mafakitale ena. Imakhala ndi thupi labwino komanso mankhwala, omwe amatha kusanthula kuchokera pazigawo zosungunuke, kukhazikika, mawonekedwe a ma vickol, etc.
1. Kusungunuka
Kusungunuka kwa Kimacell®hpmm ndi imodzi mwazinthu zofunikira kwambiri komanso zamankhwala. Itha kusungunuka m'madzi kuti apange yankho lowonekera la colloidal. Solubility imagwirizana kwambiri ndi kunenepa kwake ndi kuchuluka kwake kwa hydroxypyll ndi methyl. Nthawi zambiri, kulemera kwa mabowo kumasungunuka mosavuta, pomwe hpmc yokhala ndi kulemera kwapamwamba kwambiri kumasungunuka pang'onopang'ono. Mu mankhwala am'madzi, hpmc sapanga njira yothetsera njira yothetsera njira yothetsera njira yothetsera polymer njira. Kuphatikiza apo, HPMC imakhalanso yosungunuka bwino m'madzi ena osungunulira (monga matomoni), zomwe zimapangitsa kuti ikhale yogwiritsidwa ntchito kwambiri m'malo ena apadera.

Kufalikira kwa HPMC m'madzi kumatha kutulutsa mayankho a ku Colloidal makamaka ndi zinthu zolemera monga kuchuluka kwa kulemera, digiri yazolowa, yankho la hpmc. Pamene kuchuluka kwa HPMC kumawonjezeka, mafayilo amawonjezeka kwambiri, ndikuwoneka bwino kwa njira zopangidwa ndi ma hpmc osiyana ndi osiyana kwambiri. Ma Isclies a HPMC amagwiritsidwa ntchito kwambiri m'mafakitale a mankhwala ndi chakudya, makamaka powongolera mankhwala osokoneza bongo, okulitsa ndi othandizira.
Munjira yothetsera matendawa, mamasukidwe a HPMC nthawi zambiri amachepetsa ndi kutentha kwambiri, komwe kumawonetsa kuti HPMC ndi kutentha. Kutentha kumakhala kwakukulu kwambiri, mafayilo a HPMC yankho limatha kuchepa, zomwe zimafuna chisamaliro chapadera mu mapulogalamu ena.
3. Kukhazikika kwa mafuta
HPMC ili ndi chokhazikika champhamvu mkati mwa kutentha kwina. Kukhazikika kwake kwamafuta kumakhudzana kwambiri ndi kulemera kwa maselo, kuchuluka kwa zolowa m'malo. Kutentha kwabwinobwino, kapangidwe ka HPMC kumakhala kokhazikika komanso kosavuta kuwola. Komabe, kutentha kumakhala kwakukulu kwambiri, hpmc kumatha kupezeka pang'ono ndi matenda a hydrolysis kapena dehydroxty, omwe amakhudza momwe amagwirira ntchito.
Kukhazikika kwa ma hpmc kumathandizira kuti mukhalebe ndi magwiridwe antchito ambiri otentha (monga mu chakudya kukonza kapena zida zomangira). Komabe, kutentha kumapitilira mulingo winawake, kapangidwe ka HPMC kungawonongeke, ndikupangitsa kuwonongeka kwa magwiridwe antchito.

HPMC imawonetsa kukhazikika kwamphamvu kwamankhwala pansi pa b. Nthawi zambiri zimakhala zokhazikika pansi pa acid. Chifukwa chake, munthawi inayake, ndikofunikira kuti musinthe mtengo wa pH kuti muchepetse kukhazikika kwa HPMC.
HPMC yankho ili ndi chidziwitso china cha ph. Makamaka pamankhwala ena opangira mankhwala kapena zachilengedwe, hpmc nthawi zambiri amagwiritsidwa ntchito kukonza mitundu yovomerezeka chifukwa imatha kukhala ndi chisinthiko chosokoneza mu mfundo zosiyanasiyana za pH. Katunduyu ndi wofunikira kwambiri mu dongosolo lotulutsidwa ndi mankhwala ndipo amatha kuwongolera kumasulidwa kwa mankhwala.
5. Katundu wamakina
HPMC, ngati zinthu za polymer, zili ndi mphamvu inayake. Njira yake yothetsera magazini yopangidwa mosiyanasiyana imakhala ndi mphamvu zina komanso zotanuka. Makamaka popanga filimu, HPMC imatha kuwonetsa zinthu zabwino. Izi zimathandizira kuti ipereke chotsatsa chabwino komanso kukana nyengo mukamagwiritsidwa ntchito ngati chinthu chopanga mafilimu kapena chotsirizira pomanga.
6. Katundu wambiri
HPMC ili ndi zolimba zolimba, makamaka pamiyeso yotsika, imatha kupanga dongosolo lokhazikika ndi madzi. Khalidwe lake logawanika limagwirizana kwambiri ndi kunenepa kwake, mtundu ndi kukhazikika kwa magalimoto. Pansi pa malo oyenera, hpmc imatha kugwiritsidwa ntchito ngati thickener, othandizira kapena emulsifier, omwe amapangitsa kuti ikhale yogwiritsidwa ntchito kwambiri mu chakudya, mankhwala, zodzoladzola ndi minda ina.
7.
HPMC ili ndi zochitika zina chifukwa zili ndi ma hydrophilic ndi magulu a hydrophobic. Panthawi zina, Kimacell®hpmc imatha kuchepetsa mavuto a madzi ndikugwiritsidwa ntchito ngati chowonjezera. Mu mankhwala opangira mankhwala ndi zodzikongoletsera, hpmc amagwiritsidwa ntchito kwambiri ngati emulsiferiers ndi obalalika, omwe angalimbikitse madzi osakanikirana ndi madzi osakanikirana ndi kukhazikika kwa chinthucho.
8 ..
HPMC ili ndi zinthu zabwino kwambiri ndipo ndikugwiritsidwa ntchito kwambiri m'munda. Sizikugawidwa mosavuta ndipo imatengedwa mthupi ndipo nthawi zambiri imagwiritsidwa ntchito ngati chonyamula mankhwala osokoneza bongo kapena pokonza ma capisyules a mankhwala. Chifukwa cha kuchuluka kwake kwa zolemera zake, hpmc nthawi zambiri sizimawayankha kapena zotsatira zina komanso zovuta zina ndipo ndizoyenera makonzedwe osiyanasiyana monga pakamwa, wapamwamba komanso jakisoni.
Hpmcili ndi thupi labwino komanso mankhwala, kuphatikizapo kusungunuka bwino, mamasukidwe osinthika, kukhazikika kwamafuta, kukhazikika kwa mankhwala ndi kusakhazikika. Izi zimapangitsa kuti zigwiritsidwa ntchito kwambiri m'mafakitale ambiri monga mankhwala, chakudya, zodzola komanso zomangamanga. Kumvetsetsa mozama za thupi lake ndi mankhwala kudzathandiza kukonza ntchito zake m'minda yosiyanasiyana.
