IHydroxyethylcellulose (HEC) iyi-polymer encibilika emanzini esetshenziswa kabanzi ezimbonini ezahlukahlukene njengokwakha, izimonyo, ezemithi, nokumba uwoyela. I-HEC inezinto ezimbalwa eziyingqayizivele eziyenza ibe yinto ekhangayo embonini, okuhlanganisa ukuncibilika kwayo okuphezulu emanzini, ikhono layo lokujiya kanye nokusimamisa izixazululo ezinamanzi, kanye nokumelana kwayo nokuhlasela kwamagciwane.
Izakhiwo ze-Hydroxyethyl Cellulose (HEC)
I-HEC isuselwa ku-cellulose, i-polymer yemvelo etholakala ezinhlobonhlobo zezitshalo zezitshalo. I-cellulose ikhishwa ku-pulp yokhuni, ukotini noma eminye imithombo yemvelo bese iphathwa nge-ethylene oxide ukwenza i-hydroxyethyl cellulose. Izinga le-ethoxylation liyahlukahluka kuye ngokusetshenziswa okuhlosiwe kwe-HEC.
Enye yezinto ezibaluleke kakhulu ze-HEC ukuncibilika kwayo okuphezulu emanzini. I-HEC iyancibilika emanzini ashisayo nabandayo, yakha izixazululo ezicacile nezibonakalayo. I-solubility ye-HEC incike ezingeni lokushintshwa (DS) kanye nebanga le-viscosity. Uma iphezulu i-DS kanye nebanga le-viscosity, i-HEC iyancibilika kancane.
Enye impahla ebalulekile ye-HEC ikhono layo lokujiya kanye nokuzinzisa izixazululo ezinamanzi. I-HEC ingakha isakhiwo esifana nejeli emanzini, ngaleyo ndlela ikhulise i-viscosity yesisombululo. Lesi sakhiwo senza i-HEC ibe ukuqina okufanelekile kokwakheka kwamanzi okufana nopende, izinto zokunamathisela nemikhiqizo yokunakekela umuntu.
I-HEC iphinde imelane nokuhlaselwa kwamagciwane, okuyenza ifanelekele ukusetshenziswa emikhiqizweni yokwelapha kanye neyokunakekelwa komuntu siqu. Isebenza njenge-antiseptic ngokuvimbela ukukhula kwamagciwane kanye nesikhunta.
Ungayisebenzisa kanjani i-Hydroxyethyl Cellulose (HEC)
I-HEC isetshenziswa ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile. Nazi ezinye izibonelo zendlela i-HEC esetshenziswa ngayo ezimbonini ezahlukene.
imboni yezokwakha
I-HEC isetshenziswa njenge-thickener kanye ne-stabilizer ezintweni zokwakha ezihlukahlukene ezifana usimende, udaka kanye nama-coatings. Ithuthukisa ukusebenza kwalezi zinto, inciphise umswakama, futhi ikhulise amandla nokuqina kwazo. I-HEC iphinde isebenze njengesibophezelo ezinhlelweni zamanzi eziqinile eziqinile, ezivimbela okuqinile ekuhlukaniseni nasekuxazululeni.
Imboni yezimonyo
I-HEC isetshenziswa ezinhlobonhlobo zezimonyo ezinjengama-shampoos, ama-conditioner, nama-lotions. Isebenza njenge-thickener, emulsifier kanye ne-stabilizer, ithuthukisa ukuthungwa kwemikhiqizo futhi ivimbele ukuthi ingahlukani. I-HEC futhi ihlinzeka ngokuzwakala okubushelelezi, okusilika esikhumbeni nasezinweleni.
Imboni yezemithi
I-HEC isetshenziswa ekwenziweni kwemithi okuhlukahlukene njengamaphilisi, okhilimu, namajeli. Isebenza njenge-binder, disintegrant kanye ne-thickener ukuthuthukisa ukusebenza komkhiqizo nokuzinza. I-HEC ingaphinde ithuthukise i-bioavailability yezidakamizwa ngokuthuthukisa ukunyibilika nokuqedwa kwazo.
imboni yokumba uwoyela
I-HEC isetshenziswa njenge-viscosifier kanye ne-ejenti yokulahlekelwa uketshezi emanzini okumba i-petroleum. Ingathuthukisa umthamo wokuthwala uketshezi, ivimbele ukwakheka kobumba, futhi inciphise ukungqubuzana phakathi koketshezi nomthombo.
Ekuphetheni
IHydroxyethylcellulose (HEC) iyipolymer eguquguqukayo enezinhlobonhlobo zezakhiwo ezihlukile eziyenza ibe yinto ekhangayo ezimbonini ezahlukahlukene. I-HEC incibilika kakhulu emanzini, ingajiya futhi izinze izixazululo ezinamanzi, futhi imelana nokuhlasela kwamagciwane. Isetshenziswa ezimbonini ezehlukene njengezokwakha, izimonyo, ezemithi kanye nokumba uwoyela ngenxa yekhono layo lokuthuthukisa ukusebenza kwemikhiqizo. Ngezinzuzo zayo eziningi, i-HEC ngokungangabazeki iyimpahla ebalulekile embonini.
