I-Quaternized hydroxyethyl cellulose

I-Quaternized hydroxyethyl cellulose (QHEC) inguqulo eguquliwe ye-hydroxyethyl cellulose (HEC) esabelane nenhlanganisela ye-quaternary ammonium. Lokhu kuguqulwa kushintsha izakhiwo ze-HEC futhi kubangele i-polymer ye-cationic enezinhlobonhlobo zezinhlelo zokusebenza, kuhlanganise nemikhiqizo yokunakekelwa komuntu siqu, izindwangu, nezingubo zephepha.

I-quaternization ye-HEC ihilela ukungezwa kwenhlanganisela ye-quaternary ammonium ku-molecule ye-HEC, eyethula ukushaja okuhle ku-polymer. Inhlanganisela ye-quaternary ammonium esetshenziswa kakhulu kule njongo i-3-chloro-2-hydroxypropyl trimethylammonium chloride (CHPTAC). Le nhlanganisela isabela namaqembu e-hydroxyl ku-molecule ye-HEC, okuholela ku-molecule ye-QHEC ekhokhiswe kahle.

Esinye sezicelo eziyinhloko ze-HEC sisemikhiqizweni yokunakekelwa komuntu siqu, njengama-shampoos, ama-conditioner, nemikhiqizo yesitayela sezinwele. I-HEC ihlinzeka ngezakhiwo ezinhle kakhulu zokupholisa izinwele nokunqanda izinwele, okwenza kube lula ukukama nesitayela. I-HEC iphinde isetshenziswe njengesilungisi se-thickener ne-rheology kule mikhiqizo, ihlinzeka ngokuthungwa okunethezeka futhi ithuthukise ukusebenza okuphelele.

Ekufakweni kwezindwangu, i-HEC isetshenziswa njenge-ejenti yokulinganisa ukotini neminye imicu yemvelo. I-HEC ingathuthukisa ukuqina nokumelana nokuhuzuka kwezindwangu, izenze ziqine futhi zibe lula ukuphatha ngesikhathi senqubo yokukhiqiza. I-HEC ingaphinde ithuthukise ukunamathela kodayi namanye ama-ejenti wokuqeda endwangu, okuholela emibaleni ekhanyayo kanye nokushesha kokugeza okungcono.

I-HEC iphinde isetshenziswe ekwakhiweni kwamaphepha ukuze kuthuthukiswe ukumelana kwamanzi nokuphrinta kwephepha. I-HEC ingathuthukisa ukunamathela kokunamathela futhi inciphise ukungena kwamanzi noyinki emicu yephepha, okuholela ekuphrinteni okubukhali nokugqamile. I-HEC inganikeza nokushelela okuhle kakhulu kwendawo kanye nokucwebezela ephepheni, ithuthukise ukubukeka kwayo kanye nezakhiwo ezithintekayo.

Enye yezinzuzo ezibalulekile ze-HEC imvelo yayo ye-cationic, eyenza iphumelele kakhulu ekuhlanganiseni okuqukethe ama-anionic surfactants. Ama-Anionic surfactants avame ukusetshenziswa emikhiqizweni yokunakekelwa komuntu siqu, kodwa angasebenzisana nama-thickeners angewona ama-ionic, njenge-HEC, futhi anciphise ukusebenza kwawo. I-HEC, njenge-cationic, ingakha ukusebenzisana okuqinile kwe-electrostatic nama-anionic surfactants, okuholela ekuthuthukisweni kokuqina nokuzinza.

Enye inzuzo ye-HEC ukuhambisana kwayo nohlu olubanzi lwezinye izithako. I-HEC ingasetshenziswa nezinye izithako ze-cationic, i-anionic, ne-non-ionic ngaphandle kokuthinta ukusebenza kwayo. Lokhu kuyenza ibe isithako esiguquguqukayo esingasetshenziswa ezinhlobonhlobo zokwakheka nezinhlelo zokusebenza.

I-HEC itholakala kumabanga ahlukahlukene kanye nama-viscosities, kuye ngesicelo esithile kanye nezidingo zokwakhiwa. Ngokuvamile kunikezwa njengempushana engahlakazwa kalula emanzini noma kwezinye izincibilikisi. I-QHEC ingase futhi inikezwe njengomkhiqizo ongathathi hlangothi ngaphambili noma ozithathayo, oqeda isidingo sezinyathelo ezengeziwe zokungathathi hlangothi phakathi nenqubo yokubunjwa.

Kafushane, i-quaternized hydroxyethyl cellulose inguqulo eguquliwe ye-hydroxyethyl cellulose eye yasabela ngenhlanganisela ye-quaternary ammonium. I-HEC iyi-polymer ye-cationic enezinhlobonhlobo zezinhlelo zokusebenza, kufaka phakathi imikhiqizo yokunakekelwa komuntu siqu, izindwangu, nezingubo zephepha. I-HEC ihlinzeka ngezakhiwo ezinhle kakhulu zokumisa nokujiya, ithuthukisa ukusebenza kwama-anionic surfactants, futhi ihambisana nohlu olubanzi lwezinye izithako. Ukuguquguquka nokusebenza kwe-HEC kuyenza ibe isithako esibalulekile ekwakhiweni nasekusetshenzisweni okuhlukahlukene.
