Iimpembelelo zoBubushushu kwi-Hydroxy Ethyl Cellulose Solution
IHydroxy Ethyl Cellulose (HEC) yipolymer enyibilikayo emanzini esetyenziswa kakhulu kumashishini ahlukeneyo afana nezithambiso, amayeza, kunye nokutya njenge-thickener, binder, kunye ne-stabilizer. I-viscosity yezisombululo ze-HEC zixhomekeke kakhulu kwiqondo lokushisa, kwaye utshintsho kwiqondo lokushisa lunokuchaphazela iimpawu ezibonakalayo zesisombululo.
Xa ubushushu besisombululo se-HEC sanda, i-viscosity yesisombululo iyancipha ngenxa yokunciphisa i-hydrogen bonding phakathi kwamaketanga e-polymer. Oku kuncipha kwe-viscosity kubonakala ngakumbi kumaqondo okushisa aphezulu kwaye kubangela isisombululo esincinci, esincinci.
Ngokwahlukileyo, xa ukushisa kwesisombululo se-HEC kuyancipha, i-viscosity yesisombululo iyanda ngenxa yokunyuka kwe-hydrogen bonding phakathi kwamaketanga e-polymer. Oku kwanda kwe-viscosity kubonakala ngakumbi kumaqondo okushisa aphantsi kwaye kubangele isisombululo esikhulu, esifana ne-gel.
Ukongezelela, utshintsho kwiqondo lokushisa kunokuchaphazela ukunyibilika kwe-HEC emanzini. Kwiqondo lokushisa eliphezulu, i-HEC iba yi-soluble ngakumbi emanzini, ngelixa kumaqondo aphantsi, i-HEC iyancibilika emanzini.
Ngokubanzi, iimpembelelo zokushisa kwisisombululo se-HEC zixhomekeke ekugxininiseni kwe-polymer, uhlobo lwe-solvent, kunye nokusetyenziswa okuthe ngqo kwesisombululo se-HEC.
