Hydroxypropyl Methylcellulose
IHydroxypropylMethylcellulose (HPMC) okanye i-hypromellosesisivelas yeMethyl cellulose iitha. Yii-fibrous emhlophe okanye emhlophe okanye i-granulari-cellulose etherumgubo. Ngoku yi-cellulose iitha ngowona msebenzi ubalaseleyo wehlabathi, odibanisa ukujiya, ukuxhoma, ukusasaza, ukulinganisa kunye nokuzinzisa. I-Hydroxypropyl methyl cellulose (HPMC) ayinatyhefu, kulula ukuyisebenzisa, kwaye inyibilika ngokulula emanzini. I-polyanion kwisisombululo esinamanzi kwaye ineempawu ezibonakalayo ezizodwa. Umsebenzi othile njengoko ngezantsi:

Iimbonakalo:
1. Ukunyibilika: Kuphantse kunganyibiliki kwi-ethanol, i-ether kunye ne-acetone, kwaye inyibilika ibe yisisombululo esicacileyo okanye esincinci se-colloidal kumanzi abandayo. Inokunyibilika kwezinye izinyibilikisi eziphilayo, kwaye inokunyibilika kwi-solvent exubileyo ye-solvents yamanzi-organic.
2. Ukumelana netyuwa: Kuzinzile kwizisombululo ezinamanzi xa iityuwa zetsimbi okanye i-electrolytes ephilayo zikhona.
3. Umsebenzi womphezulu: unokusetyenziswa njengesikhuseli se-colloid, i-emulsifier kunye ne-dispersant.
4. Uzinzo lwe-PH: ixabiso le-PH lizinzile kuluhlu lwe-3.0 ~ 11.0. I-viscosity yesisombululo se-aqueous ayinakuchaphazeleka nge-asidi okanye i-alkali.

HPMC ingasetyenziswa kwiukutyabeka kwethebhulethi, njl., kunye nebakala lokutya HPMC ingasetyenziswa njengezongezo zokutya ezahlukeneyo.
Isikhokelo seHPMCImiyalelo:
1. Indlela yamanzi ashushu: Yongeza i-1/3 okanye i-2/3 yamanzi kwisikhongozeli kwaye uyifudumeze ibe ngaphezu kwama-80. I-hydroxypropyl methyl cellulose yokuqala(HPMC) inokusasazwa ngokulinganayo emanzini ashushu, kwaye emva koko wongeze inani eliseleyo lamanzi abandayo ukuya Kumanzi ashushu oludaka, epholile emva kokuvuselela.
2. Indlela yokuxuba umgubo: xuba i-hydroxypropyl methyl cellulose(HPMC) umgubo kunye nesixa esikhulu sezinye izithako zomgubo, usasaze ngokucokisekileyo ngokuxutywa okomileyo, kwaye wongeze amanzi ukuze unyibilike..
3. Indlela yokumanzisa isinyibilikisi se-organic: qala usasaze okanye umanzise i-hydroxypropyl methyl cellulose (HPMC) kunye ne-solvent ephilayo, kwaye wongeze amanzi ukuyinyibilikisa.
