4. Nto ntom ntom: 0.25-0.70g / cm3(feem ntau yog 0.5g / cm3Sab laug thiab sab xis), nrog rau kev faib ua feem ntawm 1.26-1.31.
5. Discolored xim kub: 190-200 ℃.
6. Nto nro: Ntawm 25 ℃, 2% aqueous tov yog 42-56dyn / cm.
7. Solubility: yaj nyob rau hauv dej thiab qee cov kuab tshuaj organic, xws li ib qho kev faib ua feem ntawm ethanol / dej, propane cawv / dej, dioxethane, thiab lwm yam.Aqueous cov ntsiab lus muaj cov dej num saum npoo av, siab transparency thiab ruaj khov kev ua tau zoo.Qhov solubility sib txawv nrog cov viscosity.Qhov qis dua qhov viscosity, qhov ntau dua qhov solubility, kev ua haujlwm ntawm HPMC sib txawv ntawm qhov sib txawv, thiab cov tsos ntawm HPMC dissolution hauv dej tsis cuam tshuam los ntawm tus nqi pH.
8. HPMC txo nrog cov ntsiab lus methoxy, nce gel taw tes, txo cov dej solubility, thiab kuj txo cov dej ua haujlwm.
9. HPMC kuj muaj peev xwm ntawm thickening, tsawg grey ntsev paug, pH stability, dej tuav, zoo heev membranogenesis, raws li zoo raws li ntau yam enzyme kuj, dispersion thiab adhesion.
10. Kev ua haujlwm saum npoo: HPMC aqueous tov muaj ib qho kev ua haujlwm surfactant, thiab tuaj yeem siv los ua cov tshuaj tiv thaiv colloidal, emulsifier thiab dispersant.
11. Thermal gel: Thaum HPMC aqueous tov yog rhuab mus rau ib tug tej yam kub, nws yuav opaque.Cov gel tsim los nag, tab sis nyob rau hauv tas li txias, nws rov qab mus rau lub qub tshuaj xeev.Thiab qhov kub thiab txias ntawm cov gel thiab nag lossis daus yog nyob ntawm lawv hom, concentration, thiab cua sov npaum li cas.
12. pH stability: Lub viscosity ntawm HPMC aqueous tov yuav luag tsis cuam tshuam los ntawm acid los yog hauv paus, thiab tus nqi pH kuj tseem ruaj khov nyob rau hauv thaj tsam ntawm 3.0-11.0.Yog li ntawd, viscosity ntawm cov tshuaj stabilizes thaum lub sij hawm ntev cia txheej txheem. .
13. Kev txuag dej: HPMC yog cov khoom siv txuag dej zoo heev.Cov khoom siv dav siv hauv cov khoom siv hauv tsev, khoom noj khoom haus, tshuaj pleev ib ce, thiab ntau yam.
14. Membranicity: HPMC tuaj yeem tsim cov pob tshab, tawv thiab yoog raws nyias zaj duab xis uas tuaj yeem tiv thaiv tau cov roj infiltration zoo heev.Application hauv cov zaub mov, cov cuab yeej no feem ntau siv los tswj cov dej hauv lub sijhawm txias thiab cov roj adsorbed.
15. Kev khi: Nws tuaj yeem siv los ua cov nplaum rau cov xim, xim thiab ntawv, tab sis kuj yog xim thiab nplaum.
