Kusiyana pakati pa HPMC ndi methylcellulose
HPMC (Hydroxypropyl methylcellulose) ndi methylcellulose onse amagwiritsidwa ntchito kwambiri m'mafakitale azakudya, azamankhwala, komanso osamalira anthu ngati zolimbitsa thupi, zolimbitsa thupi, zopangira ma emulsifiers, ndi zomangira. Ngakhale amagawana zofanana, pali kusiyana pakati pa HPMC ndi methylcellulose:
- Kapangidwe ka Chemical: Onse HPMC ndi methylcellulose amachokera ku cellulose, polysaccharide yochitika mwachilengedwe. HPMC ndi cellulose yosinthidwa, pomwe magulu ena a hydroxyl pa molekyulu ya cellulose asinthidwa ndi magulu a hydroxypropyl. Methylcellulose ndi cellulose yosinthidwa, pomwe magulu ena a hydroxyl pa molekyulu ya cellulose asinthidwa ndi magulu a methyl.
- Kusungunuka: HPMC imasungunuka m'madzi kuposa methylcellulose, zomwe zimapangitsa kuti zikhale zosavuta kusungunuka ndikugwiritsa ntchito popanga.
- Viscosity: HPMC ili ndi mamasukidwe apamwamba kuposa methylcellulose, zomwe zikutanthauza kuti ili ndi katundu wokhuthala bwino ndipo imatha kupanga kusasinthika kokulirapo.
- Gelation: Methylcellulose amatha kupanga gel osakaniza akatenthedwa kenako utakhazikika, pamene HPMC alibe katundu.
- Mtengo: HPMC nthawi zambiri imakhala yokwera mtengo kuposa methylcellulose.
Ponseponse, kusankha pakati pa HPMC ndi methylcellulose kudzatengera momwe angagwiritsire ntchito komanso zomwe mukufuna pakupanga. HPMC ikhoza kukondedwa chifukwa cha kusungunuka kwake komanso kusasinthasintha kwake, pamene methylcellulose ikhoza kukondedwa chifukwa cha luso lake lopanga ma gels.
