1. Ubushushu bejeli (isisombululo se-0.2%) 50-90°C.
2. Inyibilika emanzini nakwindawo eninzi ye-polar c kunye nomlinganiselo ofanelekileyo we-ethanol/amanzi, i-propanol/amanzi, i-dichloroethane, njl.njl., ayinyibiliki kwi-ether, i-acetone, i-ethanol epheleleyo, kwaye idumbe ibe yisisombululo se-colloidal esicacileyo okanye esinamafu kancinci emanzini abandayo. Isisombululo samanzi sinomsebenzi womphezulu, sibonakala kakhulu kwaye sisebenza ngokuzinzileyo.
3. I-HPMC inepropathi ye-thermal gelation. Isisombululo samanzi semveliso siyafudunyezwa ukuze senze ijeli kwaye sitshise, size sinyibilike emva kokuba sipholile. Ubushushu be-gelation beempawu ezahlukeneyo buyahluka. Ukunyibilika kuyahluka ngokwe-viscosity. Okukhona i-viscosity iphantsi, kokukhona ukunyibilika kukhulu. Iinkcukacha ezahlukeneyo ze-HPMC zinomahluko othile kwiipropati zazo, kwaye ukunyibilika kwe-HPMC emanzini akuchaphazeleki lixabiso le-pH.
4. Ubungakanani bezinto ezincinci: Izinga lokudlula kwe-mesh eli-100 likhulu kune-98.5%. Ubuninzi: 0.25-0.70g/ (ngesiqhelo malunga ne-0.4g/), ubunzima obuthile 1.26-1.31. Ubushushu bokutshintsha kombala: 180-200°C, ubushushu be-carbonization: 280-300°C. Ixabiso le-methoxyl liqala kwi-19.0% ukuya kwi-30.0%, kwaye ixabiso le-hydroxypropyl liqala kwi-4% ukuya kwi-12%. Ukuqina (22°C, 2%) 5～200000mPa .s. Ubushushu bejeli (0.2%) 50-90°C
5. I-HPMC ineempawu zokuba namandla okuqina, ukukhupha ityuwa, uzinzo lwe-PH, ukugcinwa kwamanzi, uzinzo olunemilinganiselo, ipropati entle yokwenza ifilimu, uluhlu olubanzi lokumelana nee-enzyme, ukusasazeka kunye nokuhambelana.
