I-HPMC Hydroxypropyl Methyl Cellulose CAS No.9004-65-3
Incazelo Yemikhiqizo
- IHydroxypropyl Methyl Cellulose (HPMC) iyi-ejenti yokuqina, izinhlobonhlobo ezibalulekile ku-non-ionic cellulose ether exubile.
- IHydroxypropyl Methyl Cellulose (HPMC) iwuhlobo lwe-cellulose okukhishwa kwayo nokusetshenziswa kwayo kukhule ngokushesha eminyakeni yamuva nje. I-ether engeyona i-ionic cellulose exutshwe ukotini ocolisisiwe ngochungechunge lokusabela kusetshenziswa i-propylene oxide ne-methyl chloride njengama-etherification agents ngemva kokwelashwa kwe-alkalization. Izakhiwo zayo zihlukile ngesilinganiso sokuqukethwe kwe-methoxy nokuqukethwe kwe-hydroxypropyl.
Isici soMkhiqizo
- Ukubekezelela usawoti;
- ukuzinza kwe-pH;
- Ukugcinwa kwamanzi;
- Ukuzinza kwe-Dimensional;
- Izakhiwo ezinhle kakhulu zokwakha ifilimu;
- Ukumelana okubanzi kwe-enzyme, ukuhlakazeka nokubumbana.
Ukuhlaziya Okuyisisekelo
| Izinto | Ukucaciswa |
| Ukubukeka | Impushana |
| Iphunga | Izici Ezimaphakathi |
| Umlotha % | ≤0.1 |
| inani le-pH (1%sln 25) | 4.0-8.0 |
| I-Viscosity (mpa.s) | 70000-100000 |
Izinhlelo zokusebenza
- I-HPMC isetshenziswa kabanzi ezintweni zokwakha, ezinengilazi, izinsalela zokwenziwa, izitsha zobumba, imithi, ukudla, izindwangu, ezolimo, izimonyo, ugwayi nezinye izimboni;
- Uma isetshenziswa ekukhiqizeni imikhiqizo yokuhlanza, isetshenziswa kakhulu njenge-thickener.
