Mankhwala a tsiku ndi tsiku a hpmc hydroxypropyl methylcellulose

1. Zopangira zachilengedwe, kupsa mtima pang'ono, magwiridwe antchito, chitetezo ndi chitetezo cha chilengedwe;
2. Kusungunuka kwamadzi ndi kukhuthala: kumatha kusungunuka m'madzi ozizira, kusungunula m'madzi ena osungunulira organic ndi madzi osakanikirana amadzi ndi organic solvents;
3. Makulidwe ndi mamasukidwe akuchulukirachulukira: kuchuluka pang'ono kwa kusungunuka kumapanga njira yowonekera yowoneka bwino yokhala ndi kuwonekera kwakukulu komanso magwiridwe antchito okhazikika.The solubility amasintha ndi mamasukidwe akayendedwe.Kutsika mamasukidwe akayendedwe, m'pamenenso solubility;bwino kusintha kuyenda bata kwa dongosolo;
4. Mchere kukana: HPMC ndi sanali ionic polima, amene ali wokhazikika mu njira amadzimadzi a mchere zitsulo kapena electrolytes organic;
5. Ntchito yapamtunda: Njira yamadzimadzi ya mankhwalawa imakhala ndi ntchito yapamwamba, imakhala ndi ntchito ndi katundu wa emulsification, colloid yoteteza ndi kukhazikika kwachibale;Kupanikizika pamwamba: 2% yankho lamadzi ndi 42 ~ 56dyn / masentimita;
6. Kukhazikika kwa PH: kukhuthala kwa njira yamadzimadzi kumakhala kokhazikika mkati mwa PH3.0-11.0;
7. Kusungirako madzi: HPMC's hydrophilic properties ikhoza kuwonjezeredwa ku phala, phala, ndi phala kuti musunge madzi ambiri;
8. Thermal gelation: Madzi amadzimadzi akatenthedwa ndi kutentha kwina, amakhala opaque mpaka atagwedezeka, zomwe zimapangitsa kuti yankho liwonongeke.Koma pambuyo kuzirala, izo zidzasandulika kukhala njira yothetsera vutoli.Kutentha komwe kumachitika gel osakaniza kumachitika kumadalira mtundu wa mankhwala, ndende ya yankho ndi kutentha kutentha;
9. Makhalidwe ena: zinthu zabwino kwambiri zopangira mafilimu, komanso kukana kwa ma enzyme, dispersibility ndi kumamatira.
