Iingcebiso ngokuHyilela iSelulosi yeHydroxyethyl (HEC)

I-Hydroxyethyl cellulose (HEC) yipolima enyibilikayo emanzini edla ngokusetyenziswa kumashishini ahlukeneyo ngenxa yokujiya, ukuzinzisa, kunye neempawu zokwenza ifilim. Xa usebenza ne-HEC, ukuqinisekisa ukufakwa kwamanzi okufanelekileyo kubalulekile ukuze kuphunyezwe ukusebenza okunqwenelekayo kwimixube. Nanga amanye amacebiso okufaka amanzi kwi-HEC ngokufanelekileyo:

1. Sebenzisa Amanzi Amanzi: Qala ngokusebenzisa amanzi adibeneyo okanye amanzi adityanisiweyo kwi-HEC. Ukungcola okanye i-ion ekhoyo kumanzi ompompo inokuchaphazela inkqubo ye-hydration kwaye inokukhokelela kwiziphumo ezingahambelaniyo.
2. Indlela yokuLungisa: Kukho iindlela ezahlukeneyo zokukhupha i-HEC, kubandakanywa ukuxuba okubandayo kunye nokuxuba okushushu. Ekuxubeni okubandayo, i-HEC yongezwa ngokuthe ngcembe emanzini ngokuvuselela ngokuqhubekayo ide ihlakazwe ngokupheleleyo. Ukuxuba okushushu kubandakanya ukufudumeza amanzi ukuya kwi-80-90 ° C kwaye ngokucothayo wongeza i-HEC ngelixa uvuselela de kube manzi ngokupheleleyo. Ukukhethwa kwendlela kuxhomekeke kwiimfuno ezithile zokuqulunqwa.
3. Ukongezwa kancinci: Nokuba usebenzisa ukuxuba okubandayo okanye ukuxuba okushushu, kubalulekile ukongeza i-HEC ngokuthe ngcembe emanzini ngelixa uqhuqha ngokuqhubekayo. Oku kunceda ukuthintela ukubunjwa kweengqungquthela kunye nokuqinisekisa ukusabalalisa okufanayo kweengqungquthela zepolymer.
4. Ukuvuselela: Ukuvuselela okufanelekileyo kubalulekile kwi-hydrating HEC ngokufanelekileyo. Sebenzisa i-stirrer yomatshini okanye i-high-shear mixer ukuqinisekisa ukusasazwa ngokucokisekileyo kunye nokuhanjiswa kwepolymer. Kuphephe ukusebenzisa ukuphazamiseka okugqithisileyo, njengoko kunokungenisa amaqamza omoya kwisisombululo.
5. Ixesha le-Hydration: Vumela ixesha elaneleyo lokuba i-HEC ifake amanzi ngokupheleleyo. Ngokuxhomekeke kwibakala le-HEC kunye nendlela ye-hydration esetyenzisiweyo, oku kunokuqala ukusuka kwimizuzu emininzi ukuya kwiiyure ezininzi. Landela iingcebiso zomenzi webakala elithile le-HEC elisetyenziswayo.
6. Ukulawula Ukushisa: Xa usebenzisa ukuxuba okushushu, jonga ubushushu bamanzi ngononophelo ukukhusela ukufudumala, okunokunciphisa i-polymer. Gcina ubushushu bamanzi ngaphakathi koluhlu olucetyiswayo kuyo yonke inkqubo yokufakwa kwamanzi.
7. Ulungelelwaniso lwe-pH: Kwezinye iindlela zokuxutywa, ukulungelelanisa i-pH yamanzi ngaphambi kokuba wongeze i-HEC kunokonyusa amanzi. Thetha nomenzi wechiza okanye ubhekisele kwiinkcukacha zemveliso ukuze ufumane isikhokelo kuhlengahlengiso lwe-pH, ukuba kuyimfuneko.
8. Uvavanyo kunye noLungiso: Emva kwe-hydration, vavanya i-viscosity kunye nokuhambelana kwesisombululo se-HEC ukuqinisekisa ukuba ihlangabezana neenkcukacha ezifunwayo. Ukuba uhlengahlengiso luyafuneka, amanzi ongezelelweyo okanye i-HEC inokongezwa ngokuthe ngcembe ngelixa ivuselela ukufezekisa iipropati ezifunwayo.

Ngokulandela ezi ngcebiso, unokuqinisekisa i-hydration efanelekileyo ye-hydroxyethyl cellulose (HEC) kunye nokwandisa ukusebenza kwayo kwiifomyula zakho.
