I-quaternized hydroxyethyl cellulose

I-Quaternized hydroxyethyl cellulose (QHEC) yinguqulelo elungisiweyo ye-hydroxyethyl cellulose (HEC) efunyenwe nge-quaternary ammonium compound. Olu hlengahlengiso luguqula iipropati ze-HEC kwaye luphumela kwipolymer ye-cationic enoluhlu olubanzi lwezicelo, kubandakanywa nemveliso yokunyamekela komntu, i-textile, kunye neengubo zephepha.

I-quaternization ye-HEC ibandakanya ukongezwa kwe-quaternary ammonium compound kwi-molecule ye-HEC, eyazisa intlawulo efanelekileyo kwi-polymer. Eyona nto isetyenziswa ngokuqhelekileyo i-quaternary ammonium compound kule njongo yi-3-chloro-2-hydroxypropyl trimethylammonium chloride (CHPTAC). Le ngqungquthela iphendula kunye namaqela e-hydroxyl kwi-molecule ye-HEC, okubangela ukuba i-molecule ye-QHEC ihlawulwe kakuhle.

Esinye sezicelo eziphambili ze-HEC kwiimveliso zokhathalelo lomntu, ezinjengeeshampu, iiconditioners, kunye neemveliso zesitayile seenwele. I-HEC ibonelela ngokugqwesa komgangatho kunye neempawu zokuqhawula iinwele, okwenza kube lula ukukama kunye nesimbo. I-HEC ikwasetyenziswa njenge-thickener kunye ne-rheology modifier kwezi mveliso, ukubonelela ngobunewunewu kunye nokuphucula ukusebenza ngokubanzi.

Ukusetyenziswa kwelaphu, iHEC isetyenziswa njengesixhobo sokulinganisa umqhaphu kunye nezinye iintsinga zendalo. I-HEC inokuphucula ukuqina kunye nokuxhatshazwa kwe-abrasion yeempahla, okwenza kube yinto ehlala ixesha elide kwaye kulula ukuyiphatha ngexesha lenkqubo yokuvelisa. I-HEC inokuphucula ukunamathela kwedayi kunye nezinye ii-agent zokugqiba kwilaphu, okukhokelela kwimibala eqaqambileyo kunye nokukhawuleza kokuhlamba okungcono.

I-HEC iphinda isetyenziswe kwiingubo zephepha ukuze kuphuculwe ukuxhathisa kwamanzi kunye nokuprintwa kwephepha. I-HEC inokuphucula i-adhesion ye-coating kunye nokunciphisa ukungena kwamanzi kunye ne-inki kwimicu yephepha, okubangela ukuprintwa okubukhali kunye nokuqina. I-HEC inokubonelela ngokugudileyo komphezulu kunye neglosi ephepheni, iphucula imbonakalo yayo kunye neempawu ezibambekayo.

Enye yeenzuzo eziphambili ze-HEC yindalo yayo ye-cationic, eyenza ukuba isebenze kakhulu ekuqulunqweni okuqulethe i-anionic surfactants. I-Anionic surfactants isetyenziswa ngokuqhelekileyo kwiimveliso zokunyamekela komntu, kodwa banokusebenzisana ne-non-ionic thickeners, njenge-HEC, kwaye banciphise ukusebenza kwabo. I-HEC, i-cationic, inokwenza intsebenziswano eqinile ye-electrostatic kunye ne-anionic surfactants, okukhokelela ekuphuculeni ukutyeba kunye nokuzinza.

Enye inzuzo yeHEC kukuhambelana kwayo noluhlu olubanzi lwezinye izithako. I-HEC ingasetyenziselwa kunye nezinye izithako ze-cationic, i-anionic, kunye ne-non-ionic ngaphandle kokuchaphazela ukusebenza kwayo. Oku kuyenza ibe sisithako esisebenzayo esinokusetyenziswa kuluhlu olubanzi lokuqulunqwa kunye nokusetyenziswa.

I-HEC ifumaneka kumabakala ahlukeneyo kunye ne-viscosities, kuxhomekeke kwisicelo esithile kunye neemfuno zokuqulunqa. Ngokuqhelekileyo kunikezelwa njengomgubo onokuthi usasazwe ngokulula emanzini okanye kwezinye izinyibilikisi. I-QHEC inokubonelelwa kwakhona njengemveliso ye-pre-neutralized okanye i-self-neutralizing, ephelisa imfuno yamanyathelo ongezelelweyo okunciphisa ngexesha lokuqulunqwa.

Isishwankathelo, i-quaternized hydroxyethyl cellulose yinguqulelo elungisiweyo ye-hydroxyethyl cellulose ethe yaphendulwa kunye ne-quaternary ammonium compound. I-HEC yipolymer ye-cationic enoluhlu olubanzi lwezicelo, kubandakanywa kwiimveliso zokunyamekela komntu, iingubo, kunye neengubo zephepha. I-HEC ibonelela ngokugqwesileyo komgangatho kunye neempawu zokuqina, iphucula ukusebenza kwe-anionic surfactants, kwaye iyahambelana noluhlu olubanzi lwezinye izithako. Ukuguquguquka kunye nokusebenza kwe-HEC kuyenza ibe sisithako esixabisekileyo kwimiqulu eyahlukeneyo kunye nokusetyenziswa.
