Ixabiso le-stribe yeqondo lokushisa kwi-gel kwi-HydroxyPOpyl Methylcelcelce

I-1. Ubushushu be-gene (0.2% isisombululo) i-50-90 ° C.

2. Inyibilikiswe emanzini kwaye uninzi lwepolar c kunye nenxalenye efanelekileyo ye-ethanol / amanzi, i-propanol, i-ecelotol, i-ethanol ecacileyo okanye i-turbid ecacileyo kwi-colloidal yesisombululo esindayo samanzi. Isisombululo esikhulu sinomsebenzi womphezulu, ukungafihli nto kunye nokusebenza ngokuzinzileyo.

I-3. I-HPMC inepropathi yejelo le-shirmal. Isisombululo semveliso esikhutshiweyo ukuba senze ijeli kwaye sibethiwe, emva koko sinyibilike emva kokupholisa. Iqondo lokushisa lemigaqo eyahlukeneyo lahlukile. Ukunyibilikisa kuyahluka nge-viscosity. Ezantsi kokufakwa kwe-viscosity, kokukhona ukonakala. Inkcazo eyahlukeneyo ye-HPMC inomahluko othile kwiipropathi zawo, kunye nokuchithwa kwe-HPMC emanzini akuchaphazeleki kwixabiso le-pH.

I-4. Ubungakanani bentsumpa: I-100 Mesh Sesh inkulu kune-98.5%. Ukuxinana kobuninzi: 0.25-0.70G / (ihlala ijikeleze i-0.4G /), isiphelo esithile 1.26-1.3-16-16. Iqondo lokushisa le-discolotion: 180-200 ° C, iqondo lokushisa lekhabhoni: 280-300 ° C. The methoxyl value ranges from 19.0% to 30.0%, and the hydroxypropyl value ranges from 4% to 12%. I-Viskosity (i-22 ° C, 2%) 5 ~ 200000p. Iqondo lobushushu le-gel (0.2%) 50-90 ° C

I-5. I-HPMC ineempawu zobuchule bokuthathwa, ukugcinwa kwetyuwa, ukuzinza kwamanzi, uzinzo olufanelekileyo, uluhlu oluhle lwefilimu, ukusasazeka kwemveliso.
