Imithelela Yezinga Lokushisa Ku-Hydroxy Ethyl Cellulose Solution

IHydroxy Ethyl Cellulose (HEC) iyi-polymer encibilika emanzini esetshenziswa kakhulu ezimbonini ezahlukahlukene njengezimonyo, ezemithi, nokudla njenge-thickener, binder, kanye ne-stabilizer. I-viscosity yezixazululo ze-HEC incike kakhulu ekushiseni, futhi izinguquko ekushiseni zingathinta izakhiwo ezibonakalayo zesisombululo.

Lapho izinga lokushisa lesisombululo se-HEC likhuphuka, i-viscosity yesisombululo iyancipha ngenxa yokunciphisa ukubopha kwe-hydrogen phakathi kwamaketanga e-polymer. Lokhu kuncipha kwe-viscosity kubonakala kakhulu emazingeni okushisa aphezulu futhi kubangela isixazululo esincane, esiwuketshezi.

Ngokuphambene, lapho izinga lokushisa lesisombululo se-HEC liyancipha, i-viscosity yesisombululo iyanda ngenxa yokwanda kwe-hydrogen bonding phakathi kwamaketanga e-polymer. Lokhu kwanda kwe-viscosity kubonakala kakhulu emazingeni okushisa aphansi futhi kubangela isisombululo esikhudlwana, esifana nejeli.

Ukwengeza, izinguquko ekushiseni zingathinta nokuncibilika kwe-HEC emanzini. Emazingeni okushisa aphezulu, i-HEC iyancibilika kakhulu emanzini, kuyilapho emazingeni okushisa aphansi, i-HEC incibilika kancane emanzini.

Sekukonke, imiphumela yokushisa kusixazululo se-HEC incike ekugxilweni kwe-polymer, uhlobo lwe-solvent, kanye nokusetshenziswa okuqondile kwesisombululo se-HEC.
