Ukuxuba i-hydroxyethyl cellulose (HEC) kuwumsebenzi odinga ukulawula okunembayo kanye nekhono lobuchwepheshe. I-HEC iyimpahla ye-polymer encibilikayo emanzini esetshenziswa kabanzi ekwakhiweni, ekugqokeni, ekhemisi, kumakhemikhali wansuku zonke nezinye izimboni, ezinokuqina, ukumiswa, ukubopha, i-emulsification, ifilimu-forming, i-colloid evikelayo neminye imisebenzi.
1. Khetha uhlobo olufanele lokuncibilika
I-HEC ivame ukuncibilika emanzini abandayo, kodwa ingaphinde incibilike kuma-solvents ephilayo njenge-ethanol nezingxube zamanzi, i-ethylene glycol, njll. esetshenziswa kuzicelo ezidingeka kakhulu. Izinga lamanzi kufanele lingabi nakungcola, futhi amanzi aqinile kufanele agwenywe ukugwema ukuthikameza ukuncibilika kanye nekhwalithi yesisombululo.
2. Lawula izinga lokushisa lamanzi
Ukushisa kwamanzi kunethonya elikhulu ekuhlakazweni kwe-HEC. Ngokuvamile, izinga lokushisa lamanzi kufanele ligcinwe phakathi kuka-20°C no-25°C. Uma izinga lokushisa lamanzi liphezulu kakhulu, i-HEC kulula ukuyihlanganisa futhi yakha i-gel mass okunzima ukuyihlakaza; uma izinga lokushisa lamanzi liphansi kakhulu, izinga lokuchithwa lizohamba kancane, lithinte ukusebenza kahle kokuxuba. Ngakho-ke, qiniseka ukuthi izinga lokushisa lamanzi lingaphakathi kwebanga elifanele ngaphambi kokuxuba.
3. Ukukhethwa kwemishini yokuxuba
Ukukhethwa kwemishini yokuxuba kuncike ezidingweni ezithile zohlelo kanye nesikali sokukhiqiza. Ngemisebenzi emincane noma yaselabhorethri, i-blender noma i-blender ephathwa ngesandla ingasetshenziswa. Ngokukhiqiza okukhulu, i-mixer ye-shear ephezulu noma i-disperser iyadingeka ukuze kuqinisekiswe ukuxuba okufanayo nokugwema ukwakheka kwamabhuloki ejeli. Ijubane elinyakazayo lezinto zokusebenza kufanele libe ngokumaphakathi. Ukusheshisa kakhulu kuzobangela ukuthi umoya ungene kwisixazululo futhi ukhiqize ama-bubbles; ukunensa kakhulu kungase kungayihlakazisi i-HEC ngempumelelo.
4. Indlela yokwengeza i-HEC
Ukuze ugweme ukwakheka kwamaqoqo e-gel ngesikhathi sokuchithwa kwe-HEC, i-HEC kufanele ivame ukungezwa kancane kancane ngaphansi kokugqugquzela. Izinyathelo eziqondile zimi kanje:
Ukunyakazisa kokuqala: Endaweni elungisiwe yokuhlakaza, qala i-agitator bese uyinyakazisa ngesivinini esiphakathi ukuze wenze i-vortex ezinzile oketshezini.
Ukwengeza kancane kancane: Kancane kancane futhi ngokulinganayo ufafaze i-HEC powder ku-vortex, gwema ukungeza kakhulu ngesikhathi esisodwa ukuvimbela i-agglomeration. Uma kungenzeka, sebenzisa isisefo noma ifaneli ukuze ulawule isivinini sokwengeza.
Ukugqugquzela okuqhubekayo: Ngemuva kokuthi i-HEC ingezwe ngokugcwele, qhubeka uvuselela isikhathi esithile, ngokuvamile imizuzu engu-30 kuya ku-1 ihora, kuze kube yilapho isisombululo sibonakala ngokuphelele futhi azikho izinhlayiya ezingancibilikisiwe.
5. Ukulawulwa kwesikhathi sokuchithwa
Isikhathi sokuqedwa sincike ebangeni le-viscosity le-HEC, izinga lokushisa le-medium yokuqedwa kanye nezimo ezinyakazayo. I-HEC enezinga eliphezulu le-viscosity idinga isikhathi eside sokuqedwa. Ngokuvamile, kuthatha ihora elingu-1 kuye kwayi-2 ukuze i-HEC ichithwe ngokuphelele. Uma kusetshenziswe imishini ephezulu yokugunda, isikhathi sokuchithwa singafinyezwa, kodwa ukugqugquzela ngokweqile kufanele kugwenywe ukuvimbela ukulimala kwesakhiwo samangqamuzana e-HEC.
6. Ukwengezwa kwezinye izithako
Ngesikhathi sokuqedwa kwe-HEC, ezinye izithako zingadingeka zengezwe, njengezilondolozi, izilungisi ze-pH noma ezinye izithasiselo ezisebenzayo. Lezi zithako kufanele zengezwe kancane kancane ngemuva kokuthi i-HEC ichithwe ngokuphelele, futhi ukugqugquzela kufanele kuqhutshwe ukuze kuqinisekiswe ukusatshalaliswa okufanayo.
7. Ukugcinwa kwesixazululo
Ngemuva kokuxuba, isisombululo se-HEC kufanele sigcinwe esitsheni esivaliwe ukuvimbela ukuhwamuka kwamanzi kanye nokungcoliswa kwamagciwane. Indawo yokugcina impahla kufanele igcinwe ihlanzekile, yomile futhi ikude nelanga eliqondile. Inani le-pH lesisombululo kufanele lilungiswe libe ibanga elifanele (ngokuvamile li-6-8) ukuze kunwetshwe isikhathi sokulondoloza.
8. Ukuhlolwa kwekhwalithi
Ngemuva kokuxubana, kunconywa ukwenza ukuhlolwa kwekhwalithi esixazululweni, ikakhulukazi ukuhlola imingcele efana ne-viscosity, obala kanye nenani le-pH lesixazululo ukuze kuqinisekiswe ukuthi ihlangabezana nezidingo ezilindelekile. Uma kunesidingo, ukuhlolwa kwe-microbial kungenziwa futhi ukuze kuqinisekiswe ukuhlanzeka kwesisombululo.
I-Hydroxyethyl cellulose ingaxutshwa ngempumelelo ukuze kutholwe izixazululo ze-HEC ezisezingeni eliphezulu ukuze kuhlangatshezwane nezidingo zezindawo ezahlukene zokufaka izicelo. Ngesikhathi sokusebenza, isixhumanisi ngasinye silawulwa ngokuqinile ukuze kugwenywe ukusebenzisa kabi futhi kuqinisekiswe ukuxuba okubushelelezi kanye nekhwalithi yomkhiqizo wokugcina.
