Cellulose ether HE ikurikirana, ni ukuvuga hydroxyethyl selulose, ni ifu yera kugeza amata. Irashobora gushonga mumazi ashyushye namazi akonje, ariko ntabwo byoroshye gushonga mumashanyarazi. Jinshi marike selulose ether HE ibicuruzwa bikurikirana bifite amazi akomeye, gukora firime, kurwanya umunyu ningaruka zo kubyimba. Ifite kandi ibara ryiza cyane kandi ni inyongera nziza muri latex.
Hydroxyethyl selulose HEC nikoreshwa cyane mubyimbye kandi ifite ibyiza bikurikira:
. Irashobora kuvangwa nibigize muburyo rusange (nka pigment, inyongeramusaruro, umunyu ushonga hamwe na electrolytite) nta bintu bidasanzwe. i
(2) Kubaka neza. Igifuniko cyijimye hamwe na hydroxyethyl selulose HEC ifite pseudoplastique, bityo irashobora gukoreshwa mugukaraba, gutera, guteramo roller nubundi buryo bwo kubaka. Ibyiza, kuringaniza nabyo nibyiza. i
(3) Nta ngaruka mbi kuri firime yo gutwikira. Bitewe nuburinganire bwamazi atagaragara yibiranga igisubizo cyamazi ya HEC, ntabwo byoroshye kubira ifuro mugihe cyo kubaka no kuyibyaza umusaruro, kandi ntihakunze kubaho kubyara umwobo wibirunga na pinhole. i
(4) Iterambere ryiza. Hydroxyethyl selulose HEC ifite kwibeshya cyane hamwe na binders nyinshi hamwe namabara, kuburyo irangi ryateguwe rifite ibara ryiza kandi rihamye.
(5) Ububiko bwiza. Mugihe cyo kubika irangi, irashobora gukomeza guhagarikwa no gutandukana kwa pigment, nta kibazo cyo kureremba no kumera. Hano hari amazi make hejuru y irangi. Iyo ubushyuhe bwububiko buhindutse, ububobere bwabwo bukomeza kuba bumwe. bihamye.
