Methylcellulose ke motsoako o feto-fetohang le o tenyetsehang o nang le ts'ebeliso liindastering tse fapaneng ka lebaka la thepa ea ona e ikhethang. Motsoako ona oa polysaccharide o nkiloeng ho cellulose o tumme ka bokhoni ba ona ba ho bapala likarolo tse fapaneng makaleng a fapaneng.
Lintho tsa lik'hemik'hale tsa methylcellulose:
Methylcellulose e entsoe ka etherification ea cellulose, polymer ea tlhaho e fumanehang maboteng a lisele tsa semela. Cellulose e entsoe ka li-unit tsa tsoekere tse hokahantsoeng ke li-bond tsa β-1,4-glycosidic. Ts'ebetso ea etherification e kenyelletsa ho nkela lihlopha tsa hydroxyl sebakeng sa cellulose ka lihlopha tsa methyl. Phetoho ena ea lik'hemik'hale e fana ka thepa e ikhethang ea methylcellulose, e etsa hore e qhibilihe ka metsing tlas'a maemo a itseng.
The degree of substitution (DS) e emela palo e tloaelehileng ea lihlopha tsa hydroxyl tse nkeloang sebaka ke lihlopha tsa methyl bakeng sa yuniti e 'ngoe le e 'ngoe ea tsoekere ka har'a ketane ea cellulose, e amang ho solubility, viscosity le bokhoni ba ho etsa gel ea methylcellulose. Ha DS e ntse e eketseha, ho qhibiliha metsing le ho feto-fetoha ha motsoako ka kakaretso hoa eketseha.
Litšobotsi tsa methylcellulose:
Ho qhibiliha ha Metsi: Le leng la mabaka a mantlha a ts'ebeliso e atileng ea methylcellulose ke ho qhibiliha ha eona metsing. E bontša boitšoaro bo ikhethang ka tharollo ea metsi - ho etsa gel e hlakileng le e hlakileng ha e qhibiliha metsing a batang. Thepa ena e bohlokoa lits'ebetsong ho tloha indastering ea lijo ho ea ho tsa meriana.
