Methyl cellulose

Methyl cellulose(MC) ke mofuta oa cellulose ether e tsoang ho cellulose, polymer ea tlhaho e fumanehang maboteng a lisele tsa limela.E hlahisoa ka ho hlahisa lihlopha tsa methyl ka har'a sebopeho sa cellulose ka mokhoa oa ho fetola lik'hemik'hale.Methyl cellulose e nkoa e le ea bohlokoa ka lebaka la thepa ea eona e qhibilihang ka metsing le ea ho etsa lifilimi, e leng se etsang hore e sebelisoe liindastering tse sa tšoaneng.Mona ke lintlha tsa bohlokoa tsa methyl cellulose ether:

Thepa le Litšobotsi:

  1. Sebopeho sa Lik'hemik'hale:
    • Methyl cellulose e entsoe ka ho kenya tse ling tsa lihlopha tsa hydroxyl (-OH) ka har'a ketane ea cellulose ka lihlopha tsa methyl (-OCH3).Phetoho ena e ntlafatsa ho qhibiliha ha eona ha metsi.
  2. Ho qhibiliha ha Metsi:
    • Methyl cellulose e qhibiliha haholo ke metsi, e etsa litharollo tse hlakileng le tse hlakileng ha li kopantsoe le metsi.Tekanyo ea ho qhibiliha e ka susumetsoa ke lintlha tse kang tekanyo ea ho fetola (DS) le boima ba molek'hule.
  3. Taolo ea Viscosity:
    • E 'ngoe ea mesebetsi ea mantlha ea methyl cellulose ke bokhoni ba eona ba ho sebetsa joalo ka ntho e tenya.E kenya letsoho taolong ea viscosity mefuteng e fapaneng, e etsa hore e be ea bohlokoa lits'ebetsong tse joalo ka likhomaretsi, litlolo le lihlahisoa tsa lijo.
  4. Tlhahiso ea lifilimi:
    • Methyl cellulose e na le thepa ea ho etsa lifilimi.Sena se etsa hore e tšoanelehe bakeng sa lits'ebetso moo ho batloang lifilimi tse tšesaane, tse pepeneneng holim'a metsi.E atisa ho sebelisoa ka liphahlo le liphahlo tsa lipilisi tsa meriana.
  5. Adhesion le Binder:
    • Methyl cellulose e ntlafatsa ho khomarela ka mekhoa e fapaneng.Ka lihlahisoa tsa sekhomaretsi, e tlatsetsa ho thepa ea tlamahano.Litlhareng tsa meriana, e sebetsa e le tlamahano ho metsoako ea matlapa.
  6. Stabilizer:
    • Methyl cellulose e ka sebetsa e le stabilizer ka emulsions le suspensions, e tlatsetsang botsitso le ho ts'oana ha libopeho.
  7. Paballo ea Metsi:
    • Joalo ka li-ether tse ling tsa cellulose, methyl cellulose e bonts'a thepa ea ho boloka metsi.Sena se na le thuso lits'ebetsong moo ho boloka metsi ka har'a sebopeho ho leng bohlokoa, joalo ka lisebelisoa tsa kaho.
  8. Indasteri ea Lijo:
    • Indastering ea lijo, methyl cellulose e sebelisoa e le ntho e matlafatsang le e etsang hore ho be le gel.E sebelisoa lijong tse fapa-fapaneng, ho akarelletsa le li-sauces, lijo tse theolelang le nama e phehiloeng.
  9. Meriana:
    • Methyl cellulose e sebelisoa mefuteng ea meriana, haholo-holo ha ho etsoa liforomo tsa litekanyetso tsa molomo.Sebopeho sa eona sa ho qhibiliha ha metsi le thepa ea ho etsa filimi e etsa hore e tšoanelehe bakeng sa ho roala matlapa.
  10. Lisebelisoa tsa Kaho:
    • Indastering ea kaho, methyl cellulose e sebelisoa ho etsa seretse le samente.E thusa ho ntlafatsa ts'ebetso le ho boloka metsi.
  11. Paballo ea Mosebetsi oa Botaki:
    • Ka linako tse ling methyl cellulose e sebelisoa ho boloka litšoantšo bakeng sa thepa ea eona ea sekhomaretsi.E lumella liphekolo tse khutlisoang morao 'me e nkoa e bolokehile bakeng sa lisebelisoa tse bobebe.

Phapang:

  • Ho ka ba le limaraka tse fapaneng le mefuta e fapaneng ea methyl cellulose, e 'ngoe le e' ngoe e etselitsoe lits'ebetso tse ikhethileng tse nang le phapang ea viscosity, solubility, le thepa e 'ngoe.

Ka kakaretso, methyl cellulose ether ke polima e feto-fetohang e nang le thepa e qhibilihang ka metsing le ho etsa filimi.Ts'ebeliso ea eona e akaretsa liindasteri tse fapaneng, ho kenyeletsoa liphahlo, likhomaretsi, meriana, kaho le lijo, moo litšoaneleho tsa eona tse ikhethang li kenyang letsoho molemong o lakatsehang oa lihlahisoa tsa ho qetela.
