I-HydroxyPropyl Methylcellulose(HPMC) CAS:9004-65-3 Umthengisi woMvelisi

I-Hydroxypropyl methyl cellulose yi-propylene glycol ether ye-methylcellulose apho amaqela e-hydroxypropyl kunye ne-methyl abotshelelwe kwi-anhydrous glucose ring ye-cellulose yi-ether linkages. I-Hydroxypropyl methyl cellulose yenziwa kwi-methyl cellulose ngesenzo se-alkali kunye ne-propylene oxide. Imveliso ephumayo yi-ether enyibilikayo emanzini e-cellulose equlethe amaqela e-methoxy kunye ne-hydroxypropyl. Iqondo lokutshintshwa liyi-1.08 ukuya kwi-1.83 kunye namaqela e-hydroxypropyl njengeyona nto incinci. Imhlophe ukuya kwi-off-white fibrous powder okanye iigranules. Inyibilika emanzini nakwezinye izinyibilikisi ze-organic. Inyibilika kwi-ethanol, isisombululo samanzi sinomsebenzi womphezulu, senza ifilimu encinci emva kokomiswa, kwaye sidlula kwinguqu eguqukayo ukusuka kwi-sol ukuya kwi-gel ngokufudumeza nokuphola.

Ukusetyenziswa kunye nesiphumo

IHydroxypropyl Methyl Cellulose (HPMC) ziipolymers ezinyibilikayo emanzini ezithathwe kwicellulose. Zihlala zisetyenziswa njengezithambisi, izihlanganisi, iziqambi zefilimu, kunye neearhente zokugcina amanzi. Zikwasebenza njengezixhobo zokuncedisa ukumiswa, ii-surfactants, ii-lubricants, ii-colloids zokukhusela, kunye nee-emulsifiers. Ukongeza, izisombululo zezi polymers zisebenza njengejeli yokufudumala. IHydroxypropyl methyl cellulose isetyenziswa njenge-ophthalmic lubricant, i-emulsifier kunye ne-thickening and suspending agent. Isetyenziswa kakhulu njenge-excipient kwi-pharmaceutical formulations. Isebenza njenge-food additive. Amathontsi ayo amehlo aziwa njengee-artificial tears, ezisetyenziselwa ukunciphisa ukoma kwamehlo kunye nokuqaqamba. Ifumana izicelo kwiindawo ezahlukeneyo njenge-emulsifier, i-film former, i-protective colloid, i-stabilizer, i-suspending agent, okanye i-thickener ekutyeni. Uncedo lwezonyango (i-suspending agent; i-tablet excipient; i-demulcent; i-viscosity increasing agent); i-hydrophilic carrier kwiinkqubo zokuhambisa amayeza. Kwizinto zokuncamathelisa, ii-emulsions ze-asphalt, ii-caulking compounds, ii-tile mortars, ii-plastic mixes, ii-cement, iipeyinti.
