Thepa ea Rheological ea Methyl cellulose Tharollo

Thepa ea rheological ea tharollo ea methylcellulose (MC) e bohlokoa bakeng sa ho utloisisa boitšoaro le ts'ebetso ea eona lits'ebetsong tse fapaneng. Rheology ea thepa e bua ka phallo ea eona le litšobotsi tsa deformation tlas'a khatello kapa khatello. Thepa ea rheological ea litharollo tsa MC e ka angoa ke lintlha tse kang ho tsepamisa mohopolo, mocheso, pH, le tekanyo ea ho nkela sebaka.

Viscosity

Viscosity ke e 'ngoe ea likarolo tsa bohlokoa tsa rheological tsa tharollo ea MC. MC ke lintho tse nang le viscous haholo tse ka etsang litharollo tse teteaneng ha li qhibiliha ka metsing. Viscosity ea litharollo tsa MC e ipapisitse le botsitso ba tharollo, tekanyo ea ho kenya sebaka, le mocheso. Ho phahama ha motsoako oa tharollo, ho phahamisa viscosity ea tharollo. Tekanyo ea ho kenya sebaka e boetse e ama viscosity ea tharollo ea MC. MC e nang le boemo bo phahameng ba ho fetola e na le viscosity e phahameng ha e bapisoa le MC e nang le boemo bo tlaase ba ho fetola. Mocheso o ka boela oa ama viscosity ea tharollo ea MC. Viscosity ea tharollo ea MC e fokotseha ka mocheso o ntseng o eketseha.

Shear Thinning Behaviour

Litharollo tsa MC li bonts'a boits'oaro ba ho kuta, ho bolelang hore viscosity ea bona ea fokotseha tlasa khatello ea ho kuta. Ha khatello ea ho kuta e sebelisoa ho tharollo ea MC, viscosity e fokotseha, e lumellang tharollo hore e phalle habonolo. Thepa ena ke ea bohlokoa lits'ebetsong moo tharollo e hlokang ho phalla habonolo nakong ea ts'ebetso, empa hape e hloka ho boloka botenya le botsitso ha e phomotse.

Boitšoaro ba Gelation

Litharollo tsa MC li ka kena ka har'a gelation ha li futhumetse ka holimo ho mocheso o itseng. Thepa ena e ipapisitse le boemo ba ho nkela sebaka sa MC. MC e nang le tekanyo e phahameng ea ho fetola e na le mocheso o phahameng oa gelation ha o bapisoa le MC ka tekanyo e tlaase ea ho fetola. Boitšoaro ba litharollo tsa MC bo bohlokoa lits'ebetsong tse joalo ka tlhahiso ea li-gel, jellies le li-dessert.

Thixotropy

Litharollo tsa MC li bonts'a boitšoaro ba thixotropic, ho bolelang hore viscosity ea bona e fokotseha ha nako e ntse e phomola. Ha khatello ea ho kuta e sebelisoa ho tharollo, viscosity ea eketseha.
