IHydroxYethylcellellulose: I-Shidener in Paints ethuthukisa ikhwalithi yokupenda nokusebenza

IHydroxyYethylcellulose (HEC) iyisidina esiguquguqukayo esetshenziswa kabanzi embonini yezambatho. Kuyi-polymer yemvelo ekhiqizwa ukusabela kwamakhemikhali kwe-cellulose nge-ethylene oxide ngaphansi kwezimo ze-alkaline. Inqubo ikhiqiza ama-polymers ancibilikayo ahambisana kakhulu nokwakhiwa kwama-coating asuselwa emanzini.

Inzuzo enkulu ye-HEC yikhono layo lokukhulisa ukuvumelana kakhulu nokubonakala kwezembatho ngaphandle kokuthinta ezinye izakhiwo ezakhiwe. Inokumelana okuhle kakhulu kwe-electrolyte futhi igcina amandla ayo okuqina ngisho nasebukhoneni bezinye izengezo ezinjenge-surffactants, imibala kanye nabaphangi. Lokhu kwenza i-HEC ibe mkhulu kakhulu futhi isebenze kahle ekunikezelweni kwenhlanganisela.

I-HEC incibilikisa kakhulu emanzini ngakho-ke ingahlakazeka kalula futhi ihlanganiswe kwizakhiwo zenhlamba. Lokhu kwenza inqubo yokuqina isebenze kahle futhi isebenze, ngenkathi futhi iqinisekisa ukufana kwepende ngaphandle kokwakhiwa kwama-clumps noma ama-agregates.

Enye inzuzo esemqoka ye-HEC ukuqina kwayo okuhle kakhulu, okuvimbela ukunamathela ekunciphiseni noma ukugijima ngesikhathi. Kuyasiza futhi ukuthi kwakhiwe ifilimu elifanayo elineqhawe elinezakhiwo ezinhle kakhulu, ngaleyo ndlela zithuthukise ukubukeka kwendawo ehlanganisiwe.

I-HEC nayo idlala indima ebalulekile ekwenzeni ngcono ukusebenza kwezembatho. Izakhiwo zokuqina ze-HEC nokuzinza kwenza kube yi-binder ephumelelayo kanye ne-rheology modicifier, ukusiza ukukhulisa ukuqina nokude kwezimbozo. Lokhu kubaluleke kakhulu ekugqokeni ingaphandle, okumele kubekezele izimo zezulu ezinzima nokuchayeka isikhathi eside semisebe ye-UV.

I-HEC ibuye ithuthukise ukunamathela kwe-coating ku-substrate, kanye nokumelana kwayo ku-abrasion kanye nokukhahlela. Izakhiwo zalo ezinhle kakhulu zokugcina amanzi zigqugquzela ukwakheka okungcono kokomisa nangokwefilimu, okuholela ekuhlanganisweni okufanayo nokuzinzile.

Enye yezinto eziphawuleka kakhulu ze-HEC ukuhambisana kwayo ngezinhlobo ezahlukahlukene zokupenda, kufaka phakathi upende we-latex osuselwa emanzini, upende we-alkyd, kanye nokwakheka okusekelwe ku-solvent. Lokhu kwenza kube inketho eguquguqukayo yama-coatulators we-Coatings, ongafaka i-hec ekwakhiweni kwawo ngaphandle kokukhathazeka ngokuhluleka noma imiphumela emibi engafuneki.

Ngaphezu kwezicelo zayo embonini yezembatho, i-HEC ingathola futhi ukusetshenziswa kwezinye izimboni ezinjenge-cosmetics, imithi kanye nokukhiqizwa kokudla. Ukuguquguquka kwayo kanye nokusebenza kahle kwenza kube insiza ebalulekile yezinhlelo eziningi ezahlukene.

IHydroxYethylcellellulose iyinhlangano ebalulekile, eguquguqukayo edlala indima ebalulekile ekwakhekeni nasekusebenzeni kwezimbozo. Izakhiwo zayo ezihlukile zithuthukisa ukungaguquguquki, ukubonakala, ukuqina kanye nokusebenza kwezimbozo, okwenza kube yisithako esibalulekile ekunikezelweni okuningi kwenhlanganisela. Ukuhambisana kwalo ngezinhlobo ezahlukahlukene zokupenda nezinye izengezo zenza kube yindlela ephumelelayo kakhulu yamakhambi apenda. I-Hydroxycellulose: mkhulu othuthukisa ikhwalithi yokupenda nokusebenza. Izakhiwo zayo ezihlukile zithuthukisa izakhiwo zenhlamba, ukubonana, ukuqina nokuhlakazeka, kanye nokubukeka nokubukeka kwenhlanganisela. Embonini yezambane, i-hydrogen hydroxyl homogeneous oxygen cellulose i-carbon dioxide agent esetshenziswa kabanzi ezinhlotsheni ezahlukahlukene zokuhlanganisa nezinqubo zokukhiqiza.
