I-Hydroxypropyl methyl cellulose VS methyl cellulose

1. I-Hydroxypropyl methyl celluloseXa enyibilika emanzini abandayo, amanzi ashushu anyibilikisiweyo aya kujongana nobunzima. Kodwa ubushushu bawo bokunyibilika emanzini ashushu buphezulu kakhulu kunobo be-methyl cellulose. Ukunyibilika kwe-methyl cellulose emanzini abandayo nako kuphuculwe kakhulu.

2. Ubunzima be-hydroxypropyl methyl cellulose bunxulumene nobunzima bayo be-molecular, kwaye ubunzima be-molecular obukhulu bubunzima obuphezulu. Ubushushu buya kuchaphazela nobunzima bayo, ubushushu buyanda, ubuninzi buyancipha. Nangona kunjalo, ubuninzi bobushushu obuphezulu buphantsi kunobo be-methyl cellulose. Isisombululo sizinzile xa sigcinwe kubushushu begumbi.

3. I-Hydroxypropyl methyl cellulose izinzile kwi-asidi kunye ne-alkali, kwaye isisombululo sayo samanzi sizinzile kakhulu kuluhlu lwe-pH=2~12. I-Caustic soda kunye namanzi ekalika azinampembelelo ingako kwiipropati zayo, kodwa i-alkali inokukhawulezisa izinga layo lokunyibilika kwaye iphucule i-viscosity ye-pin. I-Hydroxypropyl methyl cellulose izinzile kwi-salts ngokubanzi, kodwa xa uxinzelelo lwe-salty solution luphezulu, i-viscosity ye-hydroxypropyl methyl cellulose solution ithanda ukwanda.

4. Ukugcinwa kwamanzi kwe-hydroxypropyl methyl cellulose kuxhomekeke kubungakanani bayo bokongeza, i-viscosity, njl. Izinga lokugcina amanzi phantsi kobungakanani obufanayo bokongeza liphezulu kunele-methyl cellulose.

5. Ukuncamathela kwe-hydroxypropyl methyl cellulose kwisakhiwo se-mortar kuphezulu kunokwe-methyl cellulose.

6. I-Hydroxypropyl methyl celluloseinokumelana ngcono kwee-enzyme kune-methyl cellulose, kwaye amathuba okuwohloka kwee-enzyme kwisisombululo aphantsi kune-methyl cellulose.
