Ukuzinza kwamakhemikhali e-HEC nsuku zonke nokulawulwa kwe-viscosity

ethula:

IHydroxyethylcellulose (HEC) iyi-polymer eguquguqukayo futhi eguquguqukayo embonini yamakhemikhali abathengi, edlala indima ebalulekile ekuqiniseni ukwakheka nokulawula i-viscosity. Njenge-polymer encibilika emanzini etholakala ku-cellulose, i-HEC inezici eziyingqayizivele ezenza ilungele ukusetshenziswa okuhlukahlukene.

Qonda ukwakheka kwamangqamuzana e-HEC:

I-HEC iphuma ku-cellulose, i-polymer etholakala kakhulu eMhlabeni, etholakala ngokuyinhloko ezindongeni zamaseli ezitshalo. Ngochungechunge lwezinguquko zamakhemikhali, i-ethylene oxide yethulwa ku-cellulose ukuze yakhe i-hydroxyethyl cellulose. Lokhu kuguqulwa kwenza i-polymer incibilike emanzini, iyenze ifaneleke uhla olubanzi lwezinhlelo zokusebenza. 

Isakhiwo samangqamuzana e-HEC siqukethe umgogodla we-cellulose namaqembu e-hydroxyethyl axhunywe kumaqembu asebenzayo e-hydroxyl (-OH) amayunithi e-glucose. Lesi sakhiwo esiyingqayizivele sinikeza i-HEC kokubili izakhiwo ze-hydrophilic kanye ne-hydrophobic, ukuyivumela ukuthi ihlanganyele namanzi nezinye izinto ezinhlobonhlobo zokubunjwa.

Ukuzinza kumakhemikhali asendlini:

Ukuzinza kuyisici esiyinhloko ekwakhiweni kwama-shampoos, ama-lotions, ama-creams neminye imikhiqizo yezimonyo yansuku zonke. I-HEC ingasebenza njenge-stabilizer ephumelelayo ngenxa yekhono layo lokushintsha izakhiwo ze-rheological zokubunjwa, ukuvimbela ukuhlukaniswa kwesigaba nokugcina ubuqotho bomkhiqizo.

Ukuzinza kwe-emulsion:

I-HEC ithuthukisa ukuzinza kwe-emulsion ngokwenza ifilimu evikelayo ezungeze amaconsi kawoyela ukuvimbela ukuhlangana. Lokhu kubaluleke kakhulu emikhiqizweni efana nama-creams nama-lotions, njengoba ama-lotions azinzile aqinisekisa ngisho nokusatshalaliswa kwezithako.

Ukuzinza kokumiswa:

Emikhiqizweni equkethe izinhlayiya ezimisiwe, ezifana nezikhuhla zokucwenga noma izimonyo, i-HEC isiza ukugcina izinhlayiya zihlakazekile futhi ivimbele ukuzinza. Lokhu kusiza ukuthuthukisa ukuzinza okuphelele nobuhle bomkhiqizo.

Ukuqina kwe-pH:

I-HEC isebenza njengesivimbeli ekwenziweni, esiza ukuzinzisa kanye nokugcina i-pH yomkhiqizo. Lokhu kubalulekile emikhiqizweni yokunakekelwa komuntu siqu, njengoba i-pH ithinta ukuhambisana kwesikhumba nokusebenza kwezithako ezisebenzayo.

Ukulawulwa kwe-viscosity kumakhemikhali wansuku zonke:

I-Viscosity iyipharamitha ebalulekile enquma izindawo zokugeleza zemikhiqizo yamakhemikhali yansuku zonke. I-HEC inikeza ukulawula okusebenzayo kwe-viscosity ngokushintsha ukushuba nokuthungwa kokubunjwa.

I-Thickener:

I-HEC ivame ukusetshenziswa njenge-ejenti yokuqina emikhiqizweni efana ne-shampoo nokugeza umzimba. Inikeza i-viscosity oyifunayo, ithuthukisa ukuthungwa komkhiqizo futhi yenze kube lula ukuyisebenzisa.

Isilungisi sesimo:

Izakhiwo ze-rheological ze-HEC zingenziwa ngokwezifiso ukuze kuzuzwe ukuthungwa okuthile ekubunjweni. Lokhu kuzuzisa kakhulu emikhiqizweni efana namakhilimu nama-lotions, lapho ukuvumelana okudingekayo nokusabalala kubaluleke kakhulu ekwanelisekeni kwabathengi.

isilawuli sokugeleza:

Emikhiqizweni ewuketshezi njengensipho yezandla noma ukugeza umzimba, i-HEC isiza ukulawula izici zokugeleza ukuze kuqinisekiswe ukukhishwa komkhiqizo kalula nangokungaguquguquki.

Ekuphetheni:

Kafushane, i-hydroxyethylcellulose (HEC) idlala indima ebalulekile embonini yamakhemikhali ezimpahla, ibambe iqhaza ekuqiniseni nasekulawuleni i-viscosity yokubunjwa okuhlukahlukene. Isakhiwo sayo samangqamuzana esiyingqayizivele, esisuselwa ku-cellulose, siyinikeza izakhiwo ezihlukahlukene eziyenza ibe isithako esibalulekile ekunakekeleni komuntu siqu okuhlukahlukene kanye nemikhiqizo yezimonyo. Njengoba okulindelwe ngabathengi kuqhubeka nokuthuthuka, ukubaluleka kwe-HEC ekugcineni ukuzinza nokusebenza kokwakhiwa kwamakhemikhali kwansuku zonke kungase kukhule, kuqinise isikhundla sayo njengesithako esiyinhloko embonini.
