Thepa ea 'mele ea Hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) ke polima e qhibilihang ka metsing e sa tloaelehang e sebelisoang hangata e le setei, se tlamang le se tsitsitseng liindastering tse fapaneng.Mona ke tse ling tsa thepa ea 'mele ea HEC:

  1. Solubility: HEC e qhibiliha haholo ka metsing 'me e etsa litharollo tse hlakileng, tse nang le li-viscous tse ka kenyelletsoang habonolo ho lihlahisoa.The solubility ea HEC e angoa ke lintlha tse kang pH, mocheso le matla a ionic.
  2. Phetoho ea Rheology: HEC e ka sebetsa e le rheology modifier, e thusa ho laola phallo le viscosity ea libopeho.E ka sebelisoa ho teteaneng kapa ho fokotsa sebopeho, ho itšetlehile ka sephetho se lakatsehang.
  3. Lintho tsa ho etsa lifilimi: HEC e ka etsa filimi e matla, e tenyetsehang ha e omisitsoe, e leng se etsang hore e be ea bohlokoa lits'ebetsong tse kang liphahlo, likhomaretsi le lifilimi.
  4. Ho lumellana: HEC e lumellana le mefuta e mengata ea lisebelisoa tse ling 'me e ka sebelisoa mefuteng e mengata e fapaneng.
  5. Ho tsitsa ha mocheso: HEC e tsitsitse ka mocheso o phahameng 'me e ka sebelisoa ho etsoa ka mokhoa o hlokang mocheso oa mocheso.
  6. Ho tsitsa ha lik'hemik'hale: HEC e hanyetsana le lik'hemik'hale tse ngata 'me e ka sebelisoa ha ho etsoa lihlahisoa tse hlokang ho hanyetsa li-acids, alkalis le lik'hemik'hale tse ling.
  7. Biocompatibility: HEC ke biocompatible 'me e ka sebelisoa meriana le lihlahisoa tse ling tse kopanang le' mele.
  8. Boitšoaro ba ho kuta: HEC e bonts'a boitšoaro ba ho kuta, ho bolelang hore viscosity ea eona e fokotseha tlas'a khatello ea ho kuta.Thepa ena e ka ba molemo lits'ebetsong moo ho hlokahalang viscosity e tlase nakong ea ts'ebetso empa viscosity e phahameng e lakatseha sehlahisoa sa ho qetela.

Ka kakaretso, thepa ea 'mele ea HEC e etsa hore e be motsoako oa bohlokoa liindastering tse fapaneng.Ho qhibiliha ha eona, phetoho ea rheology, thepa ea ho etsa lifilimi, ho lumellana, botsitso ba mocheso, botsitso ba lik'hemik'hale, biocompatibility, le boitšoaro ba ho kuta moriri ho etsa hore e be motsoako oa bohlokoa oa ho etsoa ha litlolo, tlhokomelo ea botho, meriana, lijo le lisebelisoa tsa indasteri.
