HPMC (hydroxypropyl methylcellulose) ndi nkhani yosungunuka yamadzi yomwe imagwiritsidwa ntchito kwambiri mu minda yomanga, mankhwala opangira mankhwala, chakudya ndi mankhwala a tsiku ndi tsiku. Ili ndi kukula kwake, emulsization, mawonekedwe a filimu, oteteza colloid ndi zinthu zina. Mu emulsion systems, hpmc imatha kuwongolera mamasukidwe a emulsion m'njira zosiyanasiyana.
1. Mapangidwe a HopMC
Makulidwe a HPMC amakhudzidwa kwambiri ndi kulemera kwake ndi kuchuluka kwa zolowa m'malo mwake. Chokulirapo kunenepa kwambiri, mafayilo apamwamba a yankho; Ndipo kuchuluka kwa zolowetsa (ndiye kuti, digiri ya zolowetsa za hydroxypyll ndi methoxy magulu) amakhudza solubility ndi mafayilo a HPMC. Makamaka, kuchuluka kwa malo osokoneza bongo, kuwonongeka kwa madzi kwa HPMC, ndipo mafayilo amachulukana. Opanga nthawi zambiri amapereka zinthu za HPMC ndi zolemera zosiyana ndi madigiriikulu azolowa kuti akwaniritse zosowa zosiyanasiyana.
2. Gwiritsani ntchito ndende
Kukhazikika kwa HPMC mu njira yothetsera matenda ndi imodzi mwazinthu zazikulu zomwe zikukhudza mafayilo. Nthawi zambiri, kuchuluka kwa HPMC, mafayilo ochulukirapo. Komabe, mafayilo a mitundu yosiyanasiyana ya HPMC kumodzi yomweyo imatha kukhala yosiyanasiyana. Chifukwa chake, pamapulogalamu othandiza, ndikofunikira kusankha njira yoyenera ya HPMC malinga ndi zomwe zikuchitika. Mwachitsanzo, popanga mapulogalamu, kuchuluka kwa hpmc nthawi zambiri kumayendetsedwa pakati pa 0,1% ndi 1% kuti apereke mayendedwe abwino komanso ntchito yomanga.
3. Njira Yokhumudwitsa
Kuletsa kwa HPMCnso kumakhalanso kofunikira pakuwoneka komaliza. HPMC ndikosavuta kubalalika m'madzi ozizira, koma kufalikira kwa chibadwa kumachedwa; Imasungunuka mwachangu m'madzi otentha, koma ndizosavuta kwa Anglomerate. Pofuna kupewa kuphatikizika, njira yophatikizira pang'onopang'ono itha kugwiritsidwa ntchito, ndiye kuti, woyamba onjezani HPMC yamadzi ozizira kuti ithe kufafaniza mpaka kusungunuka. Kuphatikiza apo, HPMC imatha kuphatikizidwanso ndi ufa wina wowuma kenako ndikuwonjezera madzi kuti musungunuke kuti musungunuke bwino komanso kukhazikika kwa mafayilo.
4. Kutentha
Kutentha kumakhala ndi mphamvu kwambiri pakukweza kwa HPMC. Mwambiri, mafano a HPMC yankho la HPMC amachepetsa pamene kutentha kumawonjezeka. Izi ndichifukwa kutentha kwamonso kumafooketsa kulumikizana kwa hydrojeni pakati pa mamolekyulu, ndikupangitsa kuti HPMC Molecular unyolo uchepetse bwino, potero kuchepetsa ufawo. Chifukwa chake, m'mapulogalamu ofunikira mafashoni apamwamba, ma hpmc mayankho nthawi zambiri amagwiritsidwa ntchito pa kutentha kochepa. Mwachitsanzo.
5. Mtengo wa PH
Makulidwe a HPMC yankho limakhudzidwanso ndi mtengo wamtengo. HPMC ili ndi mawonekedwe apamwamba kwambiri osalowerera ndale komanso ofooka acidic, pomwe ma visccy amatsika kwambiri pansi pamankhwala a acidic kapena alkalinine. Izi ndichifukwa mawu a p Chifukwa chake, mu mapulogalamu othandiza, mtengo wa PH wa yankho umafunika kulamulidwa ndi kusungidwa mkati mwa HPMC (nthawi zambiri pH 3-11) kuonetsetsa kuti mphamvu zake zimakhala zakumwamba. Mwachitsanzo, munthawi ya chakudya, hpmc nthawi zambiri amagwiritsidwa ntchito mu zakudya za acidic monga yogurt ndi msuzi, ndipo ma visni yabwino amatha kupezeka posintha mtengo wa pH.
6. Zowonjezera zina
Mu emulsion machitidwe, mamasukidwe a HPMC amathanso kusinthidwa ndikuwonjezera ena kapena ma sol sol. Mwachitsanzo, kuwonjezera kuchuluka koyenera koyenera (monga sodium chloride) kumatha kuwonjezera mafayilo a HPMC; Ndikuwonjezera ma sortic solt monga ethanol imatha kuchepetsa ma vinya. Kuphatikiza apo, mukamagwiritsidwa ntchito limodzi ndi oundana ena (monga Xanthan chingamu, carbomer, etc.), mamasukidwe komanso kukhazikika kwa emulsion kungakhale kosinthika kwambiri. Chifukwa chake, mu kapangidwe weniweni, zowonjezera zoyenera zitha kusankhidwa monga momwe zimafunikira kukonzekeretsa mafayilo ndi ntchito ya emulsion.
HPMC imatha kukwaniritsa kuwongolera kwa emulsion kudzera pamapangidwe ake, kugwiritsa ntchito njira, njira yofanira, kutentha, pH yamtengo ndi zowonjezera. Pamapulogalamu othandiza, zinthu izi zimafunikira kuti ziwoneke bwino kuti tisankhe mtundu woyenera wa HPMC ndi zomwe zimagwiritsidwa ntchito kukwaniritsa zotsatira zabwino kwambiri. Kudzera mu mawonekedwe a sayansi yasayansi ndi njira yomwe imawongolera, HPMC ikhoza kugwira ntchito yofunika kwambiri mundalama zomanga, mankhwala opangira mankhwala tsiku lililonse, chakudya ndi mankhwala a tsiku ndi tsiku, kupereka magwiridwe antchito abwino komanso ogwiritsa ntchito.
