1. Ijeli lokushisa (0.2% isisombululo) 50-90°C.
2. Incibilika emanzini kanye nengxenye enkulu ye-polar c kanye nengxenye efanele ye-ethanol/amanzi, i-propanol/amanzi, i-dichloroethane, njll., ayincibiliki ku-ether, i-acetone, i-ethanol ephelele, futhi ikhukhumale ibe i-colloidal ecacile noma kancane emanzini abandayo.Isixazululo esinamanzi sinomsebenzi ongaphezulu, ukukhanya okuphezulu nokusebenza okuzinzile.
3. I-HPMC inendawo ye-thermal gelation.Isixazululo se-aqueous somkhiqizo siyashiswa ukuze senze ijeli futhi sikhuphuke, bese siyancibilika ngemva kokupholisa.Izinga lokushisa le-gelation lokucaciswa okuhlukile lihlukile.I-Solubility iyahlukahluka ngokuya nge-viscosity.I-viscosity ephansi, i-solubility enkulu.Ukucaciswa okuhlukile kwe-HPMC kunomehluko othile ezimpahleni zayo, futhi ukuhlakazwa kwe-HPMC emanzini akuthintwa inani le-pH.
4. Usayizi wezinhlayiya: Izinga lokuphasa elinezikhala eziyi-100 likhulu kuno-98.5%.Ukuminyana kwenqwaba: 0.25-0.70g/ (imvamisa cishe ku-0.4g/), amandla adonsela phansi athile 1.26-1.31.Izinga lokushisa lokushintsha umbala: 180-200°C, izinga lokushisa le-carbonization: 280-300°C.Inani le-methoxyl lisukela ku-19.0% ukuya ku-30.0%, futhi inani le-hydroxypropyl lisukela ku-4% ukuya ku-12%.I-Viscosity (22°C, 2%) 5～200000mPa .s.Izinga lokushisa lejeli (0.2%) 50-90°C
5. I-HPMC inezici zekhono lokuqina, ukukhishwa kukasawoti, ukuzinza kwe-PH, ukugcinwa kwamanzi, ukuzinza kwe-dimensional, impahla enhle kakhulu yokwenza ifilimu, ububanzi obubanzi bokumelana nama-enzyme, ukuhlakazeka nokuhlangana.
