I-Hydroxyethyl cellulose (HEC) iyi-polymer e-nonionic esetshenziswa kabanzi, encibilika emanzini etholakala ku-cellulose. Ukusetshenziswa kwayo okuyinhloko emikhiqizweni yamakhemikhali yansuku zonke kuvela ekhonweni layo lokuguqula i-rheology, ukuzinzisa ukwakheka, nokuthuthukisa ukuthungwa kwemikhiqizo.
Izakhiwo kanye Nendlela ye-HEC
I-HEC ibonakala ngokuqina kwayo, ukumisa okwesikhashana, ukubopha, kanye nezakhiwo ze-emulsifying. Ibonisa i-pseudoplasticity ephezulu, okusho ukuthi i-viscosity yayo iyancipha ngaphansi kwengcindezi ye-shear kodwa ibuyela esimweni sayo sokuqala uma ingcindezi isisusiwe. Lesi sakhiwo sinenzuzo ekwenziweni okuhlukahlukene njengoba sivumela imikhiqizo ukuthi ihlale iminyene futhi izinzile eshalofini kodwa kube lula ukuyisebenzisa noma ukusabalala lapho isetshenziswa.
Indlela yokusebenza kwe-HEC ilele esakhiweni sayo samangqamuzana. Amaketanga e-polymer akha inethiwekhi engabamba amanzi nezinye izakhi, enze i-matrix efana nejeli. Lokhu kwakheka kwenethiwekhi kuncike ezingeni lokufaka esikhundleni kanye nesisindo samangqamuzana e-HEC, esingahle silungiswe ukuze kuzuzwe i-viscosity oyifunayo nokuzinza ekubunjweni.
Umthelela ku-Viscosity
Umphumela Wokuqina
I-HEC ithonya kakhulu i-viscosity yemikhiqizo yamakhemikhali yansuku zonke ngokuqinisa isigaba samanzi. Emikhiqizweni yokunakekelwa komuntu siqu njengama-shampoos nama-lotions, i-HEC ikhulisa i-viscosity, okuholela ekuthunjweni okucebile kanye nombono othuthukisiwe wabathengi. Lokhu kuqina kutholakala ngokufakwa kwezinhlayiya ze-HEC, lapho ama-molecule amanzi ehlangana nomgogodla we-cellulose, okwenza i-polymer ivuvuke futhi yakhe isixazululo se-viscous.
Ukugxila kwe-HEC ekubunjweni kubalulekile ukuze kuzuzwe i-viscosity oyifunayo. Emazingeni aphansi, i-HEC inyusa ngokuyinhloko i-viscosity yesigaba samanzi ngaphandle kokuthinta izakhiwo zokugeleza kakhulu. Ekugxilweni okuphezulu, i-HEC idala isakhiwo esifana nejeli, esihlinzeka nge-viscosity ezinzile futhi ehambisanayo. Isibonelo, kuma-shampoos, ukugxila kwe-HEC kusuka ku-0.2% kuya ku-0.5% kunganikeza i-viscosity eyanele yohlelo lokusebenza olubushelelezi, kuyilapho ukugxilisa okuphezulu kungase kusetshenziselwe amajeli noma okhilimu abajiyile .
Ukuziphatha Kwe-Shear-Thinning
Imvelo ye-pseudoplastic ye-HEC ivumela imikhiqizo yamakhemikhali yansuku zonke ukuthi ibonise ukuziphatha kokugunda kwe-shear. Lokhu kusho ukuthi ngaphansi kwesenzo somshini sokuthulula, ukupompa, noma ukusabalalisa, i-viscosity iyancipha, okwenza umkhiqizo ube lula ukuwuphatha nokusebenzisa. Uma amandla okugunda esusiwe, i-viscosity ibuyela esimweni sayo sokuqala, iqinisekisa ukuthi umkhiqizo uhlala uzinzile esitsheni.
Isibonelo, ezinsipho eziwuketshezi, i-HEC isiza ukuzuza ukulingana phakathi komkhiqizo ozinzile, owugqinsi ebhodleleni kanye nensipho ewuketshezi, esakazeka kalula lapho ikhishwa. Lesi sakhiwo sibaluleke kakhulu ekwakhiweni lapho ukusetshenziswa kalula kubaluleke kakhulu, njengakumajiza namajeli ezinwele.
Umthelela Ekuzinzeni
Ukumiswa kanye ne-Emulsification
I-HEC ithuthukisa ukuzinza kwemikhiqizo yamakhemikhali yansuku zonke ngokusebenza njenge-ejenti yokumisa kanye nokuqiniswa. Ivimbela ukuhlukaniswa kwezinhlayiya eziqinile kanye nokuhlangana kwamaconsi kawoyela kuma-emulsions, ngaleyo ndlela kugcinwe umkhiqizo we-homogeneous ngokuhamba kwesikhathi. Lokhu kubaluleke kakhulu ekwenziweni okuqukethe izinto ezingancibiliki, ama-pigments, noma izinhlayiya ezimisiwe .
Ku-lotions nama-creams, i-HEC iqinisa ama-emulsions ngokukhulisa i-viscosity yesigaba esiqhubekayo, ngaleyo ndlela inciphisa ukuhamba kwamaconsi ahlakazekile kanye nezinhlayiya. Lo mshini wokuzinzisa ubalulekile ekugcineni ukuhambisana nokusebenza komkhiqizo kuyo yonke impilo yawo yeshalofu. Ngokwesibonelo, ezintweni zokugcoba ezivikela ilanga, i-HEC isiza ukugcina izihlungi ze-UV zisatshalaliswe ngokufanayo, iqinisekisa ukuvikelwa okungaguquki emisebeni eyingozi .
Ukugcinwa Komswakama Nokwakhiwa Kwefilimu
I-HEC iphinde ibambe iqhaza ekuzinzeni kokubunjwa ngokuthuthukisa ukugcinwa komswakama kanye nokwenza ifilimu evikelayo esikhumbeni noma ezinweleni. Emikhiqizweni yokunakekelwa kwezinwele, lesi sakhiwo sokwenza ifilimu sisiza ekubekeni isimo futhi sigcine izinwele zezinwele ngokubamba umswakama futhi zinikeze umgoqo ngokumelene nezici zemvelo.
Emikhiqizweni ye-skincare, i-HEC ithuthukisa ukusebenza komkhiqizo ngokunciphisa ukulahlekelwa kwamanzi esikhumbeni, inikeze umphumela wokukhipha amanzi isikhathi eside. Lesi sici siyazuzisa emikhiqizweni efana namamoisturizer namamaski obuso, lapho ukulondoloza ukugeleza kwesikhumba kuwumsebenzi obalulekile.

Imikhiqizo Yokunakekela Umuntu
Ekwakheni ukunakekelwa komuntu siqu, i-HEC isetshenziswa kabanzi ukuqina nokuqiniswa kwezakhiwo zayo. Kuma-shampoos nama-conditioner, inikeza i-viscosity oyifunayo, ithuthukisa ukuqina kwegwebu, futhi ithuthukise ukuthungwa, okuholela ekuzizweleni okungcono kakhulu komsebenzisi.
Emikhiqizweni yokunakekelwa kwesikhumba efana nokhilimu, ama-lotion, nama-gel, i-HEC isebenza njengento eqinisa futhi igxilise, okunomthelela ekuzizweleni okubushelelezi nokunethezeka komkhiqizo. Kuyasiza futhi ekusabalaliseni okulinganayo kwezithako ezisebenzayo, kuthuthukise ukusebenza kahle komkhiqizo .
Imikhiqizo Yasekhaya
Emikhiqizweni yokuhlanza yasendlini, i-HEC idlala indima ekuguquleni i-viscosity kanye nokuzinzisa ukumiswa. Ezihlahleni eziwuketshezi neziphuzo zokugeza izitsha, i-HEC iqinisekisa ukuthi umkhiqizo uhlala kulula ukuwukhipha ngenkathi ugcina i-viscosity eyanele ukuze ubambelele endaweni engaphezulu, inikeze isenzo sokuhlanza esisebenzayo.
Ezintweni zokuvuselela umoya nezithambisa izindwangu, i-HEC isiza ekugcineni ukumiswa okufanayo kwephunga nezingxenye ezisebenzayo, iqinisekisa ukusebenza okungaguquki kanye nolwazi olujabulisayo lomsebenzisi.
IHydroxyethyl cellulose (HEC) iyingxenye eguquguqukayo futhi ebalulekile ekwakhiweni kwemikhiqizo yamakhemikhali yansuku zonke. Umthelela wayo ku-viscosity nokuzinza kuyenza ibaluleke kakhulu ekudaleni imikhiqizo ehlangabezana nokulindelwe ngabathengi kokuthungwa, ukusebenza, nokusebenziseka. Ngokuthuthukisa i-viscosity, ukuqinisekisa ukuzinza komkhiqizo, kanye nokuthuthukisa izakhiwo zohlelo lokusebenza, i-HEC inikela ngokuphawulekayo ekusebenzeni kahle nasekuthandeni kwabathengi kwezinhlobonhlobo zokunakekelwa komuntu siqu kanye nemikhiqizo yasendlini. Njengoba isidingo sokwakheka kwekhwalithi ephezulu, ezinzile, kanye nokusebenziseka kalula siqhubeka sikhula, indima ye-HEC ekuthuthukisweni komkhiqizo cishe izokhula, inikeze amathuba amasha okwakheka okusha emikhiqizweni yansuku zonke yamakhemikhali.
