IHydroxyethyl cellulose (HEC) iyi-polymer encibilika emanzini evame ukusetshenziswa ezinhlotsheni ezahlukahlukene ezifana nokunamathiswa, okokunamathela, nemikhiqizo yokunakekela umuntu.Ukuhlakaza i-HEC emanzini kuyinqubo elula engafezwa ngokusebenzisa lezi zinyathelo ezilandelayo:
Khetha ibanga elilungile le-HEC: I-HEC itholakala emabangeni ahlukahlukene anesisindo samangqamuzana ahlukene namadigri okushintsha.Ukukhethwa kwebanga kuzoncika ekusetshenzisweni okuqondile kanye nezakhiwo ezidingekayo zomkhiqizo wokugcina.
Lungiselela amanzi: Isinyathelo sokuqala ukulungisa amanzi ngokukala inani elidingekayo lamanzi bese uwashisisa ezingeni lokushisa eliphakathi kuka-70-80°C.Ukushisa amanzi kuzosiza ukusheshisa inqubo yokuchithwa nokuqinisekisa ukuthi i-HEC igcwele amanzi ngokugcwele.
Engeza i-HEC emanzini: Uma amanzi esefinyelele izinga lokushisa elifunayo, kancane kancane engeza i-HEC emanzini ngenkathi ugoqa ngokuqhubekayo.Kubalulekile ukwengeza i-HEC kancane kancane ukuze ugweme ukugoqa futhi uqinisekise ukuthi ihlakazeke ngokuphelele emanzini.
Qhubeka ugqugquzela: Ngemva kokufaka i-HEC emanzini, qhubeka ugqugquzela ingxube cishe imizuzu engama-30.Lokhu kuzosiza ekuqinisekiseni ukuthi i-HEC incibilike ngokuphelele futhi inamanzi.
Vumela ingxube ukuthi iphole: Ngemva kokuthi i-HEC isihlakazwe ngokugcwele, vumela ingxube ukuthi iphole ekamelweni lokushisa.Njengoba ingxube iphola, izoshuba futhi ifinyelele i-viscosity yayo yokugcina.
Lungisa i-pH ne-viscosity: Kuye ngohlelo oluthile, kungase kudingeke ukulungisa i-pH kanye ne-viscosity yesisombululo se-HEC.Lokhu kungenziwa ngokungeza i-asidi noma isisekelo ukuze ulungise i-pH futhi ngokungeza amanzi noma i-HEC eyengeziwe ukuze ulungise i-viscosity.
ukuhlakaza i-HEC emanzini kuyinqubo elula engafezwa ngezinyathelo ezimbalwa eziyisisekelo.Ngokukhetha ibanga elifanele le-HEC, ukulungiselela amanzi ngendlela efanele, nokugqugquzela ingxube ngokuqhubekayo, kungenzeka ukuthola isisombululo se-HEC esihlakazekile ngokugcwele esingasetshenziswa ezinhlobonhlobo zezicelo.
