IBanga loKwakha HPMC
IBanga loKwakha i-HPMC HydroxypropylMethylcellulose yi aimethyliselulosietherizinto eziphuma kuyoleyoyipolima ephezulu eyenziwe ngemolekyuli elungiswe ngokuguqulwa kwemichiza yendaloumqhaphu ococekileyo okanye umthi womthinjengento ekrwada. Imveliso ye-hydroxypropyl methyl cellulose (HPMC) yahlukile kwiipolima zokwenziwa. Izinto zayo ezisisiseko yi-cellulose, i-polymer compound yendalo. Ngenxa yesakhiwo esikhethekileyo se-cellulose yendalo, i-cellulose ngokwayo ayinakho ukusabela nge-etherifying agents. Kodwa emva kokuba i-ejenti yokuvuvukala iphathwe, i-hydrogen bonds eyomeleleyo phakathi kwamatyathanga e-molecular kunye nangaphakathi kwekhonkco iyatshatyalaliswa, kwaye ukukhutshwa okusebenzayo kweqela le-hydroxyl lijika libe yi-alkali cellulose esebenzayo. Emva kokuba i-arhente ye-etherification isabele, i -OH iqela liguqulelwa kwi -OR iqela.Fngokwenene fumana HPMC.
IBanga loKwakha HPMCngumgubo omhlophe odumba ube sisinyibiliko secolloidal esicacileyo okanye esincinci kumanzi abandayo. Ineempawu zokuqina, ukudibanisa, ukusabalalisa, i-emulsification, ukubunjwa kwefilimu, ukumiswa, i-adsorption, i-gelation, umsebenzi ophezulu, ukugcinwa komswakama kunye ne-colloid yokukhusela.
