I-ether ye-cellulose yinto yokudibanisa eqhelekileyo esetyenziselwa ukwakhiwa kodaka olomileyo ukuphucula ukusebenza kwabo kunye neempawu.Esi sithako esisebenzayo sinokunika uluhlu olubanzi lweenzuzo, kubandakanywa nokusebenza okuphuculweyo, ukugcinwa kwamanzi, ukunamathela, kunye nokunye.Kweli nqaku, siza kuxoxa ngendlela yokukhetha i-cellulose ether kwizicelo zakho zodaka olomileyo.
- Cinga ngoHlobo lwe-Etere yeSelulosi Kukho iintlobo ezininzi ezahlukeneyo ze-ether ye-cellulose ezikhoyo, nganye ineempawu zayo kunye neempawu zayo.Iindidi eziqhelekileyo ze-cellulose ether ezisetyenziswa kwizicelo zodaka olomileyo ziquka:
- I-Hydroxyethyl cellulose (HEC): Olu hlobo lwe-ether ye-cellulose luyaziwa ngokugqwesa ukugcinwa kwamanzi kunye neempawu zokuqina, ezinokukunceda ukuphucula ukusebenza kunye nokunciphisa ukucutheka kwimiqulu yodaka olomileyo.
- I-Methyl cellulose (MC): I-MC isoloko isetyenziselwa udaka olomileyo njenge-binder kunye ne-adhesive agent, inika ukugcinwa kwamanzi okulungileyo, ixesha elivulekileyo kunye nokubeka iimpawu zokunciphisa.
- IHydroxypropyl methylcellulose (HPMC): I-HPMC ibonelela ngogcino lwamanzi olugqwesileyo kunye neempawu zokuphucula ukusebenza, kwaye iyaziwa ngokuguquguquka kwayo kuluhlu olubanzi lwezicelo zodaka olomileyo.
- I-Ethyl hydroxyethyl cellulose (EHEC): I-EHEC yi-HEC eguqulweyo kunye nokusebenza okungcono ngokubhekiselele kukugcinwa kwamanzi, ukusebenza kunye nokuchasana nokuqhekeka.
Kubalulekile ukukhetha uhlobo oluchanekileyo lwe-ether ye-cellulose kwisicelo sakho esithile, ngokusekelwe kwiipropati kunye neempawu ozifunayo.
- Qwalasela iNqanaba lokuTshintshwa kweemveliso ze-ether zeCellulose zingahlelwa ngakumbi ngokusekelwe kwinqanaba labo lokutshintshwa, elibhekiselele kwinqanaba apho amaqela e-hydroxyl kwi-molecule ye-cellulose afakwe endaweni yamaqela e-ether.Inqanaba eliphezulu lokutshintsha, kokukhona ukunyibilika ngakumbi kunye nokusebenza kakuhle kwe-ether cellulose iya kuba.
Nangona kunjalo, amanqanaba aphezulu okutshintsha anokukhokelela ekunciphiseni i-viscosity kunye neempawu ezimbi zokwenza ifilimu.Ke ngoko, kubalulekile ukukhetha imveliso ye-cellulose ether enenqanaba elifanelekileyo lokutshintsha isicelo sakho esithile.
- Qwalasela ubungakanani beNqanaba kunye noBunyulu Ubungakanani besuntswana kunye nobunyulu be-cellulose ether inokuchaphazela ukusebenza kwayo kunye nokusebenza kwayo kwizicelo zodaka olomileyo.Iincinci ezincinci ezincinci zivame ukunika ukusasazwa okungcono kunye nokusebenza okuphuculweyo, ngelixa iinqununu ezinkulu zinokufuna ixesha elingakumbi lokunyibilika kwaye zinokuchaphazela ukuhambelana kodaka olomileyo.
Ukongezelela, kubalulekile ukukhetha umgangatho ophezulu we-cellulose ether imveliso engenazo ukungcola okanye ukungcola, okunokuthi kube nefuthe elibi ekusebenzeni kwayo okanye kukhokelela kwimiba efana nokuguquka kombala okanye ukutyheli kodaka olomileyo.
- Qwalasela iNdlela yoKuqulunqa kunye neSicelo Okokugqibela, xa ukhetha i-ether ye-cellulose yokwenziwa kodaka lwakho olomileyo, kubalulekile ukuqwalasela uqulunqo oluthile kunye nendlela yokusetyenziswa oya kuyisebenzisa.Iimveliso ezahlukeneyo ze-ether ze-cellulose zinokuthi zifaneleke ngakumbi kwiintlobo ezithile zokwenziwa kodaka olomileyo okanye iindlela zokusetyenziswa.
Umzekelo, ukuba usebenzisa ukwakheka kodaka olomileyo olufuna umgangatho ophezulu wokugcinwa kwamanzi, imveliso ye-cellulose ether eneempawu ezigqwesileyo zokugcina amanzi njenge-HEC okanye i-HPMC inokuba lolona khetho lungcono.Ngokufanayo, ukuba usebenzisa ukwakhiwa kodaka olomileyo olufuna ukusebenza kakuhle okanye ukumelana nokuqhekeka, imveliso efana ne-EHEC inokuba yinto engcono.
Lilonke, ukukhetha imveliso ye-cellulose ether efanelekileyo kwisicelo sakho sodaka olomileyo kufuna uqwalaselo olucokisekileyo lweempawu zemveliso, iimpawu, kunye nokusebenza kuqulunqo lwakho oluthile kunye nendlela yosetyenziso.Ngokuthathela ingqalelo le miba kunye nokusebenza ngokusondeleyo nomthengisi wakho okanye umenzi, unokuqinisekisa ukuba ukhetha imveliso ye-cellulose ether yomgangatho ophezulu enikezela ukusebenza okugqwesileyo kunye nokuthembeka.
