Uburyo bwo gukururaselulose ya hydroxyethylni ukongera ubukana bw'ibice binyuze mu gushyiraho imigozi ya hydrogen hagati ya molekuli n'imbere mu molekuli, ndetse no gukurura no gufatana kw'imigozi ya molekile. Kubwibyo, uburyo bwo gukurura hydroxyethyl cellulose bushobora kugabanywamo ibice bibiri: kimwe ni uruhare rw'imigozi ya hydrogen hagati ya molekuli n'imbere mu molekuli. Umugozi ukomeye wa hydrophobic ufitanye isano na molekile z'amazi ziwukikije binyuze mu migozi ya hydrogen, ibyo bigatuma polymer ubwayo irushaho kugenda neza. Ingano y'uduce igabanya umwanya wo kugenda kw'uduce, bityo byongera ubukana bw'imigozi; icya kabiri, binyuze mu gufatana no guhurirana kw'imigozi ya molekile, imigozi ya cellulose iri mu miterere y'urusobe rw'ibice bitatu muri sisitemu yose, bityo irushaho kunoza ubukana.
Reka turebe uburyo selulosi igira uruhare mu kubika neza kw'uburyo: icya mbere, uruhare rw'imigozi ya hydrogen ibuza amazi gutembera neza, ikagira uruhare mu kubika amazi, kandi igafasha mu gukumira gutandukana kw'amazi; icya kabiri, imikoranire y'imigozi ya selulosi. Ingano y'imigozi ikora urusobe rufatanye cyangwa agace gatandukanye hagati y'ibimera, ibyuzuza n'uduce twa emulsion, bikabuza gutuza.
Ni uguhuza uburyo bubiri bwo gukora bwavuzwe haruguru butumaselulose ya hydroxyethylkugira ubushobozi bwiza cyane bwo kunoza uburyo bwo kubika neza. Mu gukora irangi rya latex, HEC yongerwaho mu gihe cyo gukubita no gutatanya iriyongera uko imbaraga zo hanze ziyongera, umuvuduko wo gukata urushaho kwiyongera, molekile zitondekwa mu cyerekezo gikurikije icyerekezo cy’amazi, kandi sisitemu yo kuzunguruka hagati y’iminyururu ya molekile irangirika, byoroshye kuyinyereraho, ubukana bwa sisitemu buragabanuka. Kubera ko sisitemu irimo ibindi bice byinshi (amabara, ibyuzuza, emulsions), iyi gahunda itunganye ntishobora gusubiza imiterere yo guhuza no guhurirana nubwo yashyirwa igihe kirekire nyuma y’uko irangi rivanzwe. Muri iki gihe, HEC ishingiye gusa ku migozi ya hydrogen. Ingaruka zo kubika no gukuba amazi zigabanya ubushobozi bwo gukubanaHEC, kandi uruhare rw'iyi miterere y'ikwirakwizwa mu buryo bwo kubika neza narwo ruragabanuka uko bikwiye. Ariko, HEC yashongeshejwe yakwirakwijwe neza muri sisitemu ku muvuduko muto wo gukurura mu gihe cyo gucika, kandi imiterere y'urusobe rw'amazi yakozwe no guhuza imiyoboro ya HEC ntiyangiritse cyane. Bityo bigaragaza ubushobozi bwo kwiyongera no kuguma mu bubiko. Birumvikana ko gukora icyarimwe kw'uburyo bubiri bwo gukurura ari ishingiro ryo kwiyongera neza kwa selulose no kwemeza ko kubika neza. Mu yandi magambo, imiterere ya selulose yashongeshejwe n'iyakwirakwijwe mu mazi izagira ingaruka zikomeye ku buryo yarushaho gukomera no ku ruhare rwayo mu kuguma mu bubiko neza.
