Phapang lipakeng tsa HPMC vs methylcellulose

HPMC (Hydroxypropyl methylcellulose) le methylcellulose ka bobeli li sebelisoa haholo indastering ea lijo, ea meriana, le ea tlhokomelo ea motho e le li-thickeners, stabilizers, emulsifiers, le li-agent tse tlamang. Leha ba arolelana lintho tse tšoanang, ho na le liphapang lipakeng tsa HPMC le methylcellulose:

1. Sebopeho sa lik'hemik'hale: Ka bobeli HPMC le methylcellulose li nkiloe ho selulose, polysaccharide e hlahang ka tlhaho. HPMC ke selulose e fetotsoeng, moo lihlopha tse ling tsa hydroxyl ka molek'hule ea cellulose li nketsoeng sebaka ke lihlopha tsa hydroxypropyl. Methylcellulose hape ke selulose e fetotsoeng, moo lihlopha tse ling tsa hydroxyl tse ka molek'hule ea selulose li ileng tsa nkeloa sebaka ke lihlopha tsa methyl.
2. Solubility: HPMC e qhibiliha haholo metsing ho feta methylcellulose, e etsang hore ho be bonolo ho qhibiliha le ho sebelisoa ha ho etsoa metsoako.
3. Viscosity: HPMC e na le viscosity e phahameng ho feta methylcellulose, ho bolelang hore e na le lisebelisoa tse betere tse teteaneng 'me e ka etsa hore ho be le botsitso bo bongata ho litlhahlobo.
4. Gelation: Methylcellulose e na le bokhoni ba ho etsa gel ha e futhumala ebe e pholile, athe HPMC ha e na thepa ena.
5. Litšenyehelo: HPMC hangata e theko e boima ho feta methylcellulose.

Ka kakaretso, khetho pakeng tsa HPMC le methylcellulose e tla itšetleha ka ts'ebeliso e khethehileng le thepa e lakatsehang ea tlhahiso. HPMC e ka ratoa bakeng sa ho qhibiliha ha eona le ho tsitsisa ho hoholo ha eona, ha methylcellulose e ka khethoa bakeng sa bokhoni ba eona ba ho etsa li-gel.
