IHydroxypropylmethylcellulose (HPMC) iphuma ku-cellulose evamise ukusetshenziswa ekwakhiweni kwemikhiqizo eyahlukene, okuhlanganisa noketshezi lokugeza izitsha.Isebenza njenge-thickener eguquguqukayo, ehlinzeka nge-viscosity nokuzinza ekwakhekeni kwe-liquid.
Ukubuka konke kwe-HPMC:
I-HPMC iwukuguqulwa kokwenziwa kwe-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo.Ikhiqizwa ngokushintsha i-cellulose amakhemikhali kusetshenziswa i-propylene oxide ne-methyl chloride.Umkhiqizo ovelayo uyi-polymer encibilika emanzini enezici eziyingqayizivele ze-rheological.
Iqhaza le-HPMC ekuhlanzeni uketshezi:
I-Viscosity Control: Omunye wemisebenzi eyinhloko ye-HPMC ekugezeni izitsha uketshezi ukulawula i-viscosity.Inikeza uketshezi ukungaguquguquki okuthile, ithuthukise ukuthungwa kwayo kanye nokugeleza kwayo.Lokhu kubalulekile ukuze kuqinisekiswe ukuthi isicoci sihlala singaphezulu futhi siwasusa kahle amafutha nama-grime.
Ukuzinza: I-HPMC ithuthukisa ukwakheka kokuqina ngokuvimbela ukuhlukana kwesigaba kanye nemvula.Isiza ukugcina umfaniswano womkhiqizo futhi uzinzile ngokuhamba kwesikhathi, iqinisekisa ukusebenza okungaguquki.
Ukucweba amagwebu okuthuthukisiwe: Ngaphezu komphumela wayo wokujiya, i-HPMC futhi isiza ukuthuthukisa izakhiwo ezigwebuzelayo zoketshezi lokugeza izitsha.Kuyasiza ukudala igwebu elizinzile elisiza ekuhlanzeni ngokucupha nokukhipha ukungcola nokungcola.
Ukuhambisana nama-surfactants: Uketshezi lokugeza izitsha luqukethe ama-surfactants, abalulekile ekuhlukaniseni amafutha.I-HPMC isebenzisana nama-surfactants ahlukahlukene, okuyenza ibe ukuqina okufanele kwalokhu kwakhiwa.
Ukucatshangelwa Kwemvelo: I-HPMC ithathwa njengenobungani bemvelo futhi iphephile ukuthi isetshenziswe emikhiqizweni yasendlini.Iyabola futhi ayibeki ubungozi obubalulekile empilweni yomuntu noma endaweni ezungezile.
Izicelo kanye nokwakheka:
I-HPMC ivamise ukungezwa ekwakhiweni koketshezi lokugeza izitsha phakathi nenqubo yokukhiqiza.Inani le-HPMC elisetshenzisiwe lincike ku-viscosity oyifunayo nezinye izidingo ezithile zomkhiqizo.Abakhiqizi bacabangela izici ezifana nohlobo lwe-surfactant nokugxila, ileveli ye-pH, kanye nemigomo yokusebenza iyonke.
IHydroxypropyl methylcellulose (HPMC) idlala indima ebalulekile njengokujiya oketshezini lokuwasha izitsha, inikeze ukulawulwa kwe-viscosity, ukuzinza kanye namagwebu athuthukisiwe.Ukuhambisana kwayo nama-surfactants kanye nobungane bemvelo kuyenza ibe ukukhetha okudumile ekwakhiweni komkhiqizo wokuhlanza indlu.
