IHydroxypropyl methylcellulose, ekwaziwa ngokuba yihypromellose kunye necellulose hydroxypropyl methyl ether, yenziwe ngecotton cellulose esulungekileyo kakhulu kwaye ifakwe i-etherified ngokukodwa phantsi kweemeko zealkaline.
umehluko:
iimpawu ezahlukeneyo
I-Hydroxypropyl methylcellulose: i-powder emhlophe okanye emhlophe efana ne-fiber okanye i-granules, yeentlobo ezahlukeneyo ze-non-ionic kumxube we-cellulose, le mveliso yi-semi-synthetic, i-polymer viscoelastic engasebenzi.
I-Hydroxyethyl cellulose yifayibha emhlophe okanye etyheli, engenavumba, engeyotyhefu okanye umgubo oqinileyo, eyona nto iphambili ekrwada yi-alkali cellulose kunye ne-ethylene oxide etherification, eyi-non-ionic e-soluble cellulose ether.
Ukusetyenziswa kwahlukile
Kwishishini lepeyinti, i-hydroxypropyl methylcellulose ine-solubility efanelekileyo emanzini okanye kwi-solvents ye-organic njenge-thickener, dispersant kunye ne-stabilizer.I-Polyvinyl chloride isetyenziselwa ukususwa kwepeyinti yokumisa i-polymerization ukulungiselela i-polyvinyl chloride, esetyenziswa ngokubanzi kwisikhumba, iimveliso zephepha, ukugcinwa kweziqhamo kunye nemifuno, iingubo kunye namanye amashishini.
I-Hydroxypropyl methylcellulose: iphantse ingabikho kwi-ethanol epheleleyo, i-ether, i-acetone;I-soluble kwisisombululo se-colloidal esicacileyo okanye esine-turbid kumanzi abandayo, asetyenziswa ngokubanzi kwiingubo, ii-inki, iifayibha, ukudaya, ukwenza iphepha, izimonyo, izibulala-zinambuzane, iiminerali Ukusetyenzwa kwemveliso, ukubuyiswa kwe-oyile kunye namashishini amayeza.
ukunyibilika okwahlukileyo
I-Hydroxypropyl methylcellulose: iphantse ingabikho kwi-ethanol epheleleyo, i-ether, i-acetone;Inyibilika kwisisombululo se-colloidal esicacileyo okanye esinamafu kancinane kumanzi abandayo.
I-Hydroxyethyl cellulose (HEC): Inokulungiselela izisombululo kwiindidi ezahlukeneyo ze-viscosity, kwaye ineempawu ezilungileyo zokunyibilikisa ityuwa kwi-electrolytes.
