I-Hydroxyethyl cellulose iyi-polymer encibilikayo emanzini engeyona i-ionic eyenziwe nge-cellulose, into yemvelo ye-polymer, ngokusebenzisa uchungechunge lwezinqubo zamakhemikhali. Iyinto eqinile efana nempuphu emhlophe noma ephuzi, engenaphunga futhi engenambitheki, engancibilika emanzini abandayo nasemanzini ashisayo, futhi izinga lokuncibilika liyakhula ngokukhuphuka kwezinga lokushisa. Ngokuvamile, ayincibiliki ezinyibilikisini eziningi eziphilayo. Isetshenziswa njengesithambisi kanye nesiqinisi kupende we-latex. Kulula ukuhlakazeka emanzini abandayo ngenani le-pH elingaphansi noma elilingana no-7, kodwa kulula ukuhlangana ku-alkaline liquid, ngakho-ke ngokuvamile ilungiswa kusengaphambili ukuze isetshenziswe kamuva, noma amanzi abuthakathaka e-acid noma isixazululo se-organic senziwe sibe yi-slurry, futhi ingaxutshwa nezinye izinhlayiya. Izithako zomile zixutshwe ndawonye.
Izici ze-hydroxyethyl cellulose:
I-HEC iyancibilika emanzini ashisayo noma abandayo, futhi ayivuthi uma izinga lokushisa eliphezulu noma libila, okwenza ibe nezici eziningi zokuncibilika kanye nokuthamba, kanye ne-gelation engashisi.
Ingasebenza ndawonye nezinye izinhlobo eziningi zama-polymer ancibilika emanzini, ama-surfactant, kanye nosawoti, futhi iyisithako esihle kakhulu se-colloidal sezixazululo eziqukethe ama-electrolyte aqukethe ukugcwala okuphezulu.
Umthamo wokugcina amanzi uphindwe kabili kunowe-methyl cellulose, futhi unokulawulwa okungcono kokugeleza kwamanzi.
Uma kuqhathaniswa ne-methyl cellulose eyaziwayo kanye ne-hydroxypropyl methyl cellulose, ikhono lokuhlakaza le-HEC libi kakhulu, kodwa ikhono lokuvikela i-colloid yilona elinamandla kakhulu.
Ukwakhiwa okuhle kakhulu; inezinzuzo zokonga abasebenzi, akulula ukuconsa, ukulwa nokuwa, ukulwa nokuqhekeka okuhle, njll.
Ukuhambisana kahle nama-surfactants ahlukahlukene kanye nezilondolozi ezisetshenziswa kupende we-latex.
I-viscosity yokugcina izinzile, okungavimbela i-hydroxyethyl cellulose ejwayelekile ekunciphiseni i-viscosity yepende le-latex ngesikhathi sokugcina ngenxa yokubola kwama-enzyme.
