I-HPMC (i-Hydroxypropyl Methyl Cellulose) yinto yokuncamathelisa esetyenziswa ngokubanzi xa kusenziwa. Yimathiriyeli yepolymer enamathele ngokugqwesileyo, uzinzo, ukwenza ifilimu kunye neempawu ezityebileyo, kwaye isetyenziswa kakhulu kumashishini amayeza, ukutya, ukwakhiwa kunye nokwaleka.
1. Ubume beMichiza kunye neempawu ezisisiseko ze-HPMC
I-HPMC ifumaneka nge-partial methylation kunye ne-hydroxypropylation ye-cellulose yendalo. Iqela le-hydroxyl (-OH) kwisakhiwo salo se-molecular sithatyathelwa indawo liqela le-methoxy (-OCH3) okanye iqela le-hydroxypropyl (-CH2CHOHCH3). Le nkqubo yokuguqulwa inika i-HPMC ebalaseleyo ukunyibilika kwamanzi kunye ne-viscoelasticity. Ngokukodwa, i-HPMC inokuchithwa ngokukhawuleza emanzini abandayo ukwenza isisombululo esizinzileyo se-colloidal, esine-viscosity enhle kunye nokunamathela kwisisombululo esinamanzi. Ukongezelela, inani elikhulu lamaqela e-hydrophilic aqulethwe kwisakhiwo se-molecular ye-HPMC yenza ukuba ikwazi ukugcina iimpawu zokubambelela kakuhle kwindawo yomswakama ophezulu, osisiseko esibalulekileyo sokusetyenziswa kwayo ngempumelelo kwiintlobo ezahlukeneyo zokuqulunqa.
2. Iinzuzo zokusebenza kwe-HPMC
