Hydroxypropyl methylcellulose (HPMC)ndi polima yosunthika yomwe imagwiritsidwa ntchito m'mafakitale monga mankhwala, zomangamanga, zodzola, chakudya, ndi chisamaliro chamunthu. Kukhuthala kwa HPMC kumagwira ntchito yofunika kwambiri pakuzindikiritsa kuyenerera kwake pamagwiritsidwe osiyanasiyana. The mamasukidwe akayendedwe amatengera molecular kulemera, mlingo wa m'malo, ndi ndende. Kumvetsetsa magiredi oyenera a viscosity ndikofunikira pakusankha HPMC yoyenera pazosowa zamakampani.
Kuyeza kwa Viscosity
Kukhuthala kwa AnxinCel®HPMC kumayesedwa mu njira zamadzimadzi pogwiritsa ntchito viscometer yozungulira kapena capillary. Muyezo woyezera kutentha ndi 20 ° C, ndipo kukhuthala kumawonetsedwa mumasekondi a millipascal (mPa·s kapena cP, centipoise). Makalasi osiyanasiyana a HPMC ali ndi ma viscosity osiyanasiyana kutengera zomwe akufuna.
Makanema a Viscosity ndi Ntchito Zawo
Gome ili m'munsili likuwonetsa ma viscosity wamba a HPMC ndi magwiritsidwe ake ofanana:
| Magiredi a Viscosity (mPa·s) | Kuyikira Kwambiri (%) | Kugwiritsa ntchito |
| 5-100 | 2 | Madontho a maso, zowonjezera chakudya, kuyimitsidwa |
| 100-400 | 2 | Zopaka pamapiritsi, zomangira, zomatira |
| 400 - 1,500 | 2 | Emulsifiers, mafuta, machitidwe operekera mankhwala |
| 1,500 - 4,000 | 2 | Zolimbitsa thupi, zinthu zosamalira munthu |
| 4,000 - 15,000 | 2 | Kumanga (zomatira matailosi, zopangira simenti) |
| 15,000 - 75,000 | 2 | Kuwongolera-kumasulidwa mankhwala formulations, kumanga grouts |
| 75,000 - 200,000 | 2 | Zomatira zowoneka bwino kwambiri, kulimbitsa simenti |
Zinthu Zomwe Zimakhudza Kukhuthala
Zinthu zingapo zimakhudza kukhuthala kwa HPMC:
Kulemera kwa Molecular:Apamwamba maselo kulemera kumabweretsa kuwonjezeka mamasukidwe akayendedwe.
Digiri ya Kusintha:Chiŵerengero cha magulu a hydroxypropyl ndi methyl zimakhudza kusungunuka ndi kukhuthala.
Kuyikira Kwambiri:Kuyika kwakukulu kumabweretsa kukhuthala kwakukulu.
Kutentha:Viscosity imachepa ndi kutentha kowonjezereka.
pH Sensitivity:Mayankho a HPMC ndi okhazikika mkati mwa pH ya 3-11 koma amatha kutsika kunja kwamtunduwu.
Mtengo wa shear:HPMC imawonetsa zinthu zomwe sizili za Newtonian, zomwe zikutanthauza kuti kukhuthala kumachepa chifukwa cha kumeta ubweya.
Zolinga Zogwiritsira Ntchito
Zamankhwala:HPMC imagwiritsidwa ntchito popanga mankhwala kuti amasulidwe komanso ngati chomangira pamapiritsi. Magiredi otsika kwambiri (100–400 mPa·s) amawakonda ngati zokutira, pomwe magiredi apamwamba (15,000+ mPa·s) amagwiritsidwa ntchito popanga zotulutsa mosalekeza.
Zomanga:AnxinCel®HPMC imagwira ntchito ngati chosungira madzi komanso zomatira muzinthu zopangidwa ndi simenti. Magiredi owoneka bwino kwambiri (opitilira 4,000 mPa·s) ndi abwino kuwongolera magwiridwe antchito komanso mphamvu zomangirira.
Zodzoladzola ndi Zosamalira Munthu:Mu shamposi, mafuta odzola, ndi zonona, HPMC imagwira ntchito ngati thickener ndi stabilizer. Kukhuthala kwapakati (400–1,500 mPa·s) kumapereka mwayi wokwanira pakati pa kapangidwe kake ndi kayendedwe kake.
Makampani a Chakudya:Monga chowonjezera cha chakudya (E464), HPMC imathandizira mawonekedwe, kukhazikika, komanso kusunga chinyezi. M'munsi mamasukidwe akayendedwe magiredi (5-100 mPa·s) kuonetsetsa kubalalitsidwa koyenera popanda kukhuthala kwambiri.
Kusankhidwa kwaMtengo wa HPMCmamasukidwe akayendedwe kalasi zimadalira ntchito anafuna, ndi m'munsi mamasukidwe akayendedwe magiredi oyenera zothetsera amafuna zochepa thickening ndi apamwamba mamasukidwe akayendedwe sukulu ntchito formulations kuti amafuna zomatira amphamvu ndi kukhazikika katundu. Kuwongolera kawonekedwe koyenera kumatsimikizira kugwira ntchito bwino m'mafakitale opanga mankhwala, zomangamanga, chakudya, ndi zodzoladzola. Kumvetsetsa zomwe zimathandizira kukhuthala kumathandizira kukhathamiritsa kugwiritsa ntchito HPMC pazinthu zosiyanasiyana zamafakitale.
