Umehluko phakathi kwe-HPMC ne-HEC

I-Hydroxypropyl Methylcellulose, eyaziwa nangokuthi i-Hypromellose kanye ne-cellulose hydroxypropyll methyl ether, yenziwa kusuka kukotini emsulwa kakhulu ukotini futhi ifakwe ngokukhethekile ngaphansi kwezimo ze-alkali.

umehluko:

Izici ezihlukile

I-Hydroxypropyl methylcellulose: I-white noma emhlophe ye-fiber-efana ne-powder noma ama-granule ahlukahlukene, okungokwezinhlobo ezahlukahlukene ezingezona ze-ionic engxenyeni yeselula, lo mkhiqizo uyi-polymer ye-sycoelastic, engasebenzi.

I-Hydroxyyethyl celtulose iyi-fiber emhlophe noma ephuzi, engenamphundla, engenalo ubuthi noma i-powder eqinile, impahla eqinile eqinile yi-alkali ye-cellulose ne-ethylene oxide ether.

Ukusetshenziswa kwehlukile

Embonini yepende, i-Hydroxypropyllylylylylylyly ine-soubelity enhle emanzini noma izixazululo ze-organic njengomuntu omkhulu, ohlakazekile ne-stabilizer. I-Polyvinyl Chloride isetshenziswa njenge-remover yokupenda yokumiswa kwe-polymerization ukulungiselela i-polyvinyl chloride, esetshenziswa kabanzi ngesikhumba, imikhiqizo yamaphepha, ukulondolozwa kwemifino, izindwangu zezithelo, izindwangu kanye neminye imithambo.

I-Hydroxypropyl methylcellulose: cishe insoluble ku-ethanol ngokuphelele, ether, acetone; Soluble kukhambi le-colloidal esobala noma elishukumisayo emanzini abandayo, esetshenziswa kabanzi ekuhlolweni, ama-inks, imicu, ukudonsa, izimonyo, ukucubungula ama-pesticides, ukulungiswa kwamafutha emikhakheni yezemithi.

I-solubity ehlukene

I-Hydroxypropyl methylcellulose: cishe insoluble ku-ethanol ngokuphelele, ether, acetone; incibilika kusixazululo esikhanyayo noma esinamafu kancane emanzini abandayo.

IHydroxYethyl Cellulose (HEC): Ingalungiselela izixazululo ku-viscosity ehlukile, futhi inezakhiwo ezinhle zokucibilikisa usawoti zama-electrolyte.
