IHydroxypropyl methylcellulose (HPMC) ayiyona ipulasitiki ngomqondo wendabuko.Iphuma ku-cellulose evame ukusetshenziswa ezimbonini zemithi, zokudla, ezokwakha nezokunakekela umuntu.Nakuba ingenzi njengama-plasticizers asetshenziswa kuma-polymers, ibonisa izakhiwo ezithile ezingaphikisana nemiphumela yokwenza ipulasitiki kwezinye izinhlelo zokusebenza.
Ukuhlola ngokugcwele isihloko se-HPMC kanye neqhaza layo ezimbonini ezihlukahlukene, singahlola ukwakheka kwayo kwamakhemikhali, izakhiwo, ukusetshenziswa, kanye nezinzuzo ezingaba khona kanye nokubi.Ukuqonda okuphelele kwe-HPMC kuzonikeza ukuqonda ekusetshenzisweni kwayo okuhlukile nokuthi kungani ithathwa njengesithako esibalulekile ekwenziweni okuningi.
Isakhiwo samakhemikhali kanye nezakhiwo ze-HPMC
Isakhiwo samakhemikhali:
I-HPMC i-semi-synthetic polymer etholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo.Amaqembu e-Hydroxypropyl kanye ne-methyl ethulwa ngokuguqulwa kwamakhemikhali.Lokhu kuguqulwa kushintsha izici zomzimba nezamakhemikhali ze-cellulose, okuholela ekuhlanganisweni nokusebenza okuthuthukisiwe.
isici:
I-Hydrophilic: I-HPMC iyancibilika emanzini futhi ine-hygroscopic kakhulu, iyenza ifanele ukwakheka okuhlukahlukene okudinga ukugcinwa kwamanzi noma ukukhishwa okulawulwayo.
Ukwenza ifilimu: Inezinto zokwenza ifilimu ezakha ifilimu evikelayo uma ifakwe endaweni engaphezulu, okwenza ukuthi ibe usizo ezinhlobonhlobo zemithi kanye nezinto zokwakha.
I-ejenti ejiyayo: I-HPMC ivamise ukusetshenziswa njenge-ejenti yokujiya ezixazululweni ezinamanzi.I-viscosity yayo iyanda ngokugxila, okuvumela ukulawula ukuhambisana kokwakhiwa kwe-liquid.
Ukuzwela kwezinga lokushisa: Amamaki athile e-HPMC ayahlehliswa ngokushisa, okusho ukuthi angabhekana nezinguquko zesigaba ezihlehliswayo ngokushintsha kwezinga lokushisa.
Ukusetshenziswa kwe-HPMC ezimbonini ezahlukene
1. Imboni yezemithi:
I-Tablet Coating: I-HPMC ivamise ukusetshenziswa njengento yokuhlanganisa amaphilisi embonini yezemithi.Inikeza isendlalelo esivikelayo, ilawula ukukhululwa kwezidakamizwa, futhi ithuthukise ukubukeka kwethebhulethi.
Izixazululo ze-Ophthalmic: Emathonsini esweni nasezixazululweni ze-ophthalmic, i-HPMC ingathuthukisa i-viscosity futhi ithuthukise isikhathi sokugcina endaweni ye-ocular.
2. Imboni yokudla:
I-ejenti ejiyayo: I-HPMC isetshenziswa njenge-ejenti yokuqina emikhiqizweni yokudla ehlukahlukene, okuhlanganisa amasoso, amasobho nemikhiqizo yobisi.
I-Emulsifier: Kwezinye izinhlelo zokusebenza zokudla, i-HPMC ingasebenza njenge-emulsifier, ithuthukise ukuqina kwe-emulsion.
3. Imboni yezokwakha:
Izinamathiselo Zethayela: Ukwengezwa kwe-HPMC kokunamathelayo kuthayela kuthuthukisa ukusebenza, ukugcinwa kwamanzi namandla ebhondi.
Izigxobo namaPlaster: Zisetshenziswa ezintweni zokwakha ezifana nodaka namapulasi ukuze kuthuthukiswe ukunamathela nokusebenza.
4. Imikhiqizo yokunakekelwa komuntu siqu:
Ukwakhiwa kwezihloko: Kokhilimu, izinto zokuthambisa nokunye ukwakheka kwezihloko, i-HPMC isiza ukuthuthukisa ukuthungwa, ukuqina nomuzwa wesikhumba womkhiqizo.
Imikhiqizo Yokunakekela Izinwele: I-HPMC itholakala kweminye imikhiqizo yokunakekelwa kwezinwele ngenxa yezakhiwo zayo zokwakheka kwefilimu kanye nezimo.
Izinzuzo kanye Nobubi be-HPMC
inzuzo:
I-Biocompatibility: I-HPMC ngokuvamile ibhekwa njengephephile ukusetshenziselwa abantu futhi isetshenziswa kakhulu ekwenziweni kwemithi nokudla.
I-Versatility: Inezakhiwo ezihlukahlukene futhi ifanele izimboni ezihlukahlukene kanye nokwakheka.
Ukugcinwa kwamanzi: Imvelo eyi-hydrophilic ye-HPMC isiza ekugcineni amanzi, okungaba yinzuzo kwezinye izinhlelo zokusebenza.
ukushiyeka:
Izindleko: I-HPMC ingabiza kakhulu uma iqhathaniswa nezinye izithasiselo.
Ukuzwela Kwezinga Lokushisa: Ngenxa yemvelo ehlehliswayo yamanye amabanga e-HPMC, okunye ukwakheka kungase kuthintwa ukushintsha kwezinga lokushisa.
Ekuphetheni
Yize i-HPMC ingeyona ipulasitiki ngomqondo wendabuko, izakhiwo zayo ezihlukile ziyenza ibe isithako esibalulekile ezimbonini ezahlukahlukene.Ibonisa ukuguquguquka kwayo njengefilimu yangaphambili, i-thickener kanye ne-ejenti yokugcina amanzi kwezemithi, ukudla, ukwakhiwa kanye nezicelo zokunakekelwa komuntu siqu.Ukuqonda ukwakheka kwamakhemikhali, izakhiwo, kanye nokusetshenziswa kwe-HPMC kubalulekile kubaqulunqi nabacwaningi abafuna ukuthuthukisa ukwakheka ukuze bahlangabezane nezidingo ezithile.Izinzuzo zokusebenzisana kwe-biocompatibility kanye nokuguquguquka zidlula ubungozi obungaba khona, okwenza i-HPMC ibe yinketho edumile ezimbonini eziningi.
