Ijeli ye-HPMC

IHydroxypropyl methylcellulose (HPMC) iwuhlobo lwe-cellulose ether esetshenziswa ezinhlelweni ezihlukene, okuhlanganisa njenge-ejenti ejikisayo, i-thickener, emulsifier, stabilizer, ne-ejenti elengayo.Kuyi-polymer encibilika emanzini etholakala ku-cellulose, futhi ivamise ukusetshenziswa emikhiqizweni yokudla, emithini yemithi kanye neyezimonyo.I-HPMC iphinde isetshenziselwe ukwenza amajeli, okuyizinhlelo eziqinile kancane ezakhiwe uketshezi oluhlakazwe ku-matrix eqinile.Amajeli e-HPMC asetshenziswa ekusetshenzisweni okuhlukahlukene, okuhlanganisa ukulethwa kwezidakamizwa, izimonyo, nemikhiqizo yokudla.

Amajeli e-HPMC akhiwa lapho i-HPMC incibilika ku-solvent, njengamanzi.Njengoba ikhambi liphola, ama-molecule e-HPMC akha inethiwekhi evalela isincibilikisi, enze ijeli.Izici zejeli zincike ekugxilweni kwe-HPMC, uhlobo lwe-solvent, nezinga lokushisa.Amajeli akhiwe kusukela ku-HPMC ngokuvamile abonisa ngale futhi anokuhambisana okufana nojeli.

Amajeli e-HPMC angasetshenziswa ezinhlelweni ezahlukahlukene.Embonini yezemithi, amajeli e-HPMC asetshenziselwa ukuletha izidakamizwa emzimbeni.Ijeli ingakhiwa ukuze ikhulule umuthi isikhathi eside, okuvumela ukulethwa kwezidakamizwa okuqhubekayo.Amajeli e-HPMC nawo asetshenziswa kuzimonyo, njengamafutha okugcoba nokhilimu, ukuze anikeze ukuthungwa okubushelelezi, okunokhilimu.Emikhiqizweni yokudla, amajeli e-HPMC asetshenziswa njengeziqinisi neziqinisi.

Amajeli e-HPMC anezinzuzo ezimbalwa ngaphezu kwamanye ama-ejenti ajelling.Azinabo ubuthi, azicasuli futhi ziyabola.Futhi kulula ukuzisebenzisa futhi zingakhiwa ukuze zihlangabezane nezidingo ezithile.Amajeli e-HPMC nawo azinzile phezu kwebanga elibanzi lamazinga okushisa namazinga e-pH.

Naphezu kwalezi zinzuzo, kukhona ezinye izithiyo ekusebenziseni HPMC gels.Abiza kakhulu kunamanye ama-ejelling, futhi kungaba nzima ukuwancibilikisa kwezinye izincibilikisi.Ukwengeza, amajeli e-HPMC awanamandla njengamanye ama-ejeli, futhi angathambekela ku-syneresis (ukuhlukaniswa kwejeli ibe yisigaba esiwuketshezi nesiqinile).

Sekukonke, amajeli e-HPMC ayithuluzi eliwusizo lezinhlelo zokusebenza ezahlukahlukene.Azinabo ubuthi, azicunuli, futhi ziyabola, futhi zingakhiwa ukuze zihlangabezane nezidingo ezithile.Kodwa-ke, ayabiza kakhulu kunamanye ama-ejelling, futhi kungaba nzima ukuwancibilikisa kwezinye izincibilikisi.Ukwengeza, azinamandla njengamanye ama-gelling agents, futhi angakwazi ukuthambekela ku-syneresis.
