Hydroxypropyl methylcellulose (hpmc) ndi gawo lopanda madzi osungunuka ndi mainmer omwe adakhazikitsidwa ndi kusintha kwa mankhwala a cellulose. Amagwiritsidwa ntchito kwambiri mu chakudya, mankhwala, zodzoladzola komanso makonda omanga, makamaka ngati zomata, kukula, emulsifier ndi kuyimilira wothandizila kukonzekera mafoni. Pakufunsira ntchito, mawonekedwe a ma vicko a HPMC Aquaous yankho ndikofunikira pakuchita kwake m'malo osiyanasiyana.
1. Kapangidwe ndi katundu wa hydroxypropyll methylcellulose
Kapangidwe ka HPMC kumakhala ndi magulu awiri, hydroxypropyl (-ch₂Chohch₃) ndi methyl (-Och₃) Zomwe zimapangitsa kuti kukhala ndi mphamvu yabwino yamadzi ndi kusinthika kosinthika. Unyolo wa HPMC Molecular ali ndi kapangidwe kake kolimba, koma amathanso kupanga mawonekedwe a mawonekedwe atatu mu madzi, zomwe zimapangitsa kuti mafakitsidwe. Kukula kwake kwa maselo ake, mtundu wa magalamumu komanso digiri ya zolowetsa (mwachitsanzo, digiri ya hydroxyppyl ndi methyl kulower a gawo lililonse) kukhala ndi mphamvu yofunika pakusintha.
2. Makhalidwe a Viccoss of Aquous yankho
Makhalidwe a ViccCon a HPMC Aquaous yankho limagwirizana kwambiri ndi zinthu monga kuchuluka kwa zomwe zimachitika, kulemera kwa ma cent, kutentha ndi mtengo wa zosungunulira. Nthawi zambiri, mafayilo a njira ya HPMC Aquneous amawonjezeka ndi kuchuluka kwa ndende yake. Maonekedwe ake akuwonetsa kuti siachilengedwe omwe sanali achi New
(1) Zotsatira za kuzunzika
Pali ubale wina pakati pa mafayilo a HPMC Aquaous yankho ndi ndende yake. Pamene kuchuluka kwa HPMC kumawonjezeka, njira zosinthira mu mankhwala am'madzi zimakulitsidwa, ndipo kukonzekera ndi kuphatikizika kwa ma unyolo kumawonjezeka, zomwe zimapangitsa kuti mamasukidwe athe. M'malo otsika, mawonekedwe a njira ya HPMC Aquious imachulukana mogwirizana ndikuchulukitsa kwa ndende, koma m'malo okhazikika, kukula kwa ma vischeza kwa njirayi kumakhala kokhazikika ndikufika pamtengo wokhazikika.
(2) Zotsatira zazolemera
Kulemera kwa HPMC kumakhudza mwachindunji mafayilo a yankho lake la madzi. HPMC yokhala ndi zolemera zapamwamba zimakhala ndi unyolo wautali ndipo imatha kupanga mawonekedwe ochulukirapo atatu okhala ndi ma netwoous mu madzi am'madzi, zomwe zimayambitsa mafayilo apamwamba. Mosiyana ndi izi, hpmc yokhala ndi kulemera kwam'munsi ili ndi mawonekedwe a losuser ndi mafayilo otsika chifukwa cha unyolo wake wamfupi. Chifukwa chake, mukamagwiritsa ntchito, ndikofunikira kusankha hpmc ndi kulemera koyenera kuti mukwaniritse malingaliro abwino.
(3) Zotsatira za kutentha
Kutentha ndi chinthu chofunikira chomwe chikukhudza mafayilo a HPMC Aquaous yankho. Pamene kutentha kumawonjezeka, kusuntha kwa mamolekyulu amadzi kumakulitsa komanso kukweza kwa yankho nthawi zambiri kumachepa. Izi ndichifukwa choti kutentha kwa HPMC kwazitsulo kumawonjezeka komanso kulumikizana pakati pa mamolekyules kumachepa, potero kuchepetsa mawilowo. Komabe, kuyankha kwa HPMC kuchokera ku mabatire kapena mitundu ku kutentha kumathanso kukhala yosiyanasiyana, kotero kutentha kwa kutentha kumafunika kusinthidwa mogwirizana ndi zofunikira zina.
(4) Zotsatira za mtengo wa pH
HPMC yokha ndi yopanda iyonic, ndikuwoneka kuti yankho lake la madzi limakhala lovuta kusintha mu PH. Ngakhale mawonedwe a HPMC omwe ali ndi zigawo za acidic kapena zosalowerera, kusungunuka ndi mawonekedwe a HPMC idzakhudzidwa ndi acidic. Mwachitsanzo.
3. Kusanthula kwa Rhealogical kwa mawonekedwe a ma victo a HPMC Aquaus yankho
Khalidwe la RHCOAGOL la HPMC Aquious nthawi zambiri limawoneka ngati madzi osakhala a Newtonia, zomwe zikutanthauza kuti ma viscy samangokhudzana ndi zinthu monga njira yothetsera mavuto komanso kunenepa. Nthawi zambiri, mitengo yotsika yotsika, hpmc am'madzi imawonetsa mamasukidwe apamwamba, pomwe kuchuluka kwa mphete kumawonjezeka, ma virus amachepetsa. Khalidweli limatchedwa "Shear kupatulira" kapena "kukameta ubweya" ndipo ndikofunikira kwambiri mu mapulogalamu ambiri. Mwachitsanzo, m'magawo a zokumba, kukonzekera kwa mankhwala kwa mankhwala, etc.
4. Zinthu zina zomwe zikukhudza mafayilo a HPMC Aquaous yankho
(1) Zotsatira zamchere
Kuphatikiza kwa michere ya mchere (monga sodium chloride) kumatha kuwonjezera mafayilo a HPMC Aquaous yankho. Izi ndichifukwa mchere umatha kukulitsa kulumikizana pakati pa mamolekyulu posintha mphamvu ya ionic yothetsera vutoli, kotero kuti ma molekyulu a HPMC amapanga mawonekedwe ochulukirapo, potero kukulirani mamasuki. Komabe, zotsatira za mtundu wamchere komanso kukhazikika pa ufa kuyeneranso kusintha malinga ndi zochitika zina.
(2) Zotsatira za zowonjezera zina
Powonjezera zowonjezera (monga zowonjezera, ma policr, etc.) ku HPMC Aquaous yankho limakhudzanso mafayilo. Mwachitsanzo, ogwiritsa ntchito amatha kuchepetsa mamasukidwe a HPMC, makamaka pomwe chidwi chachikulu ndi zinthu zambiri. Kuphatikiza apo, ma poizoni ena kapena mapepala amathanso kulumikizana ndi HPMC ndikusintha zomwe zimapangitsa kuti zitheke.
Machitidwe ahydroxypypyl methylcellulose Madzi am'madzi amakhudzidwa ndi zinthu zambiri, kuphatikizapo kuchuluka, kuchepa kwa maluso, kutentha kwa mafakitale, ndipo amagwiritsidwa ntchito kwambiri m'minda yosiyanasiyana ya mafakitale. Kuzindikira ndi Kuzindikira Makonda awa kumathandiza kuti athe kugwiritsa ntchito HPMC munjira zosiyanasiyana. Pamapulogalamu othandiza, mtundu woyenera wa HPMC ndi njira zoyenera kusankhidwa malinga ndi zofunikira kuti mupeze mawonekedwe abwino ndi ma virukitala.
