Ukugcinwa kwamanzi kwe-cellulose kuchaphazeleka kwizinto ezininzi, kuquka i-viscosity, ukongezainani, iqondo lobushushu thermogelation, ubungakanani amasuntswana, iqondo crosslinking, kunye nezithako esebenzayo.
I-Viscosity: Iphezulu i-viscosity yeiselulosi ether, kokukhona amandla ayo okugcina amanzi anamandla. Oku kungenxa yokuba i-celluloseetherkunye ne-viscosity ephezulu inokuthintela ngcono ukulahlekelwa kwee-molecule zamanzi.
Imali eyongeziweyo: Njengomlinganiselo weselulosietherukongezwa okongeziweyo, ukugcinwa kwayo kwamanzi kuya kwanda. Oku kungenxa yokuba i-cellulose eninzi inokwenza ulwakhiwo lwenethiwekhi exineneyo, enokugcina amanzi ngcono.
Ubushushu be-Thermogelation: Kuluhlu oluthile, iqondo lokushisa eliphezulu le-thermogelation, liphezuluukugcinwa kwamanziizinga leselulosiether. Oku kungenxa yokuba ubushushu obuphezulu bunokwenza iimolekyuli zeselulosi zidumbe kwaye zisasazeke ngcono, ngaloo ndlela iphucula amandla ayo okugcina amanzi.
Ubungakanani be-particle: Ubungakanani obuncinci be-particle bunokuphucula ukugcinwa kwamanzi kwi-cellulose kuba iincinci ezincinci zinokubonelela ngommandla omkhulu, onceda ukuphucula intsebenziswano phakathi kwama-molecule.
I-Degree of crosslinking: Iqondo le-crosslinking ye-cellulose nayo ichaphazela ukugcinwa kwayo kwamanzi. Ukuphakama kweqondo le-crosslinking, intsebenziswano enamandla phakathi kwee-molecule ze-cellulose, ezinokuthi zenze isakhiwo sothungelwano esizinzile kunye nesixineneyo, ngaloo ndlela kuphuculwe ukugcinwa kwamanzi.
Izithako ezisebenzayo: Izithako ezisebenzayo kwiiselulosi, njengezinto ezinyibilikayo kunye ne-polysaccharides, nazo zichaphazela ukugcinwa kwamanzi. Ezi zithako ezisebenzayo zinokusebenzisana kunye neamolekyu ze-cellulose, ngaloo ndlela zitshintsha iimpawu zayo zokugcina amanzi.
Ukongezelela, izinto ezifana nexabiso le-pH kunye nokugxininiswa kwe-electrolyte nazo zichaphazela ukugcinwa kwamanzi kwi-celluloseether. Kwizicelo ezisebenzayo, ezi zinto kufuneka zikhethwe kwaye zilungelelaniswe ngokweemfuno ezithile kunye neemeko zokufezekisa eyona mpembelelo ilungileyo yokugcina amanzi.
