Selulose ya ethyl (EC)ni eteri ya cellulose itari ionic ikomoka kuri cellulose karemano binyuze muri ethylation. Imiterere yayo yihariye y’umubiri n’imiti ituma ikoreshwa cyane mu gusiga, imiti, ibiryo, n’inganda.
1. Imiterere y'ibanze
1.1. Imiterere ya Molekile n'Ubushongerwe bwayo
Selulose ya ethyl iboneka binyuze mu gushyira mu buryo igice cy’amatsinda ya hydroxyl ya molecule ya selulose. Ubushyuhe bwayo mu mazi no gushonga kwayo biratandukanye bitewe n’urwego rwa ethoxyl substitution (DE). EC ntishongera mu mazi ariko ishongera mu bintu bitandukanye bya organic solvents, nka alcool, ketones, na hydrocarbons zihumura neza. Kubwibyo, ikunze gukoreshwa mu gukora filime no gukurura mu buryo bwa organic solvents.
1.2. Guhagarara neza k'ubushyuhe
EC igaragaza ubushyuhe buhamye cyane, akenshi ikomeza imiterere yayo ihamye ku bushyuhe buri hagati ya 150°C na 200°C kandi irwanya kubora. Ibi biyiha amahirwe mu gutunganya ubushyuhe bwinshi no gushyiraho thermosetting.
1.3. Imiterere ya mekanike n'iy'umubiri
Filimi za EC zigaragaza gukomera no koroha cyane. Filimi zirabonerana kandi ziraryoshye nyuma yo gushingwa, kandi zishobora kunoza neza uburyo ibikoresho bitoha. Byongeye kandi, ifu ya EC ishobora gutemba neza, bigatuma byoroha gutunganya no gutegura ibisubizo bimwe.
2. Imiterere y'imikorere
2.1. Ubunini n'Ubusunika
EC ishongeshejwe mu bintu bishongesha ibinyabuzima ikora amazi afite ubushyuhe bwinshi, yongera ubushyuhe bw'umubiri bityo ikanoza imiterere ya rheological. Mu gusiga irangi, irangi n'amarangi, EC ishobora gukora nk'ikintu gikomeza ubushyuhe no kugabanya ubushyuhe, ikabuza irangi n'ibirungo guhagarara neza no kunoza ubuziranenge bw'umubiri.
2.2. Gutunganya no Kurinda Filimi
Ibisubizo bya EC bikora firime zihoraho kandi zoroshye ku buso butwikiriwe, bitanga imiterere myiza yo kurinda. Filime zigaragaza ubushobozi bumwe na bumwe bwo kwirinda amazi n'amavuta kandi zishobora gukoreshwa mu kurinda ubuso bw'ibiti, ibyuma n'imiti.
2.3. Gushushanya no gusiga
Mu nganda zikora imiti, EC ikunze gukoreshwa mu gutwikira ibinini kugira ngo ikomeze gusohora. Kubera ko idashonga mu mazi ariko ikagenda isohoka buhoro buhoro mu nzira y'igifu, ishobora kugena igipimo cyo gusohora imiti no kongera ubushobozi bwo kuyikoresha.
2.4. Guhindura Ubucucike n'Uburyo bwo Gutembera
Mu guhindura uburemere bwa molekile n'urugero rwa ethoxy rwa EC, ubukana bw'umuti bushobora kugenzurwa mu buryo bworoshye kugira ngo buhuze n'ibisabwa mu buryo butandukanye. EC ifite uburemere bwinshi bwa molekile ikora ibisubizo bifite ubukana bwinshi, mu gihe EC ifite uburemere buke bwa molekile ikwiriye sisitemu zifite ubukana buke.
3. Porogaramu
3.1. Udupira n'amabara
Mu gusiga amarangi ku mbaho, amarangi y’imodoka, na wino zicapa, EC ntiyongera gusa imbaraga zo kuringaniza no guhisha, ahubwo inanongera ubushobozi bwo koroshya firime no kudakoresha imiti, bigatuma ubuso bwo gusiga burushaho kuba bwiza kandi burambye.
3.2. Imiti n'ibicuruzwa by'ubuvuzi
EC ikoreshwa mu gusiga ibinini n'udupira tw'imiti ndetse no mu gusiga imiti irekurwa mu buryo buhoraho kugira ngo igenzure igipimo cyo gusohora imiti no kunoza imikorere y'umurwayi. Ishobora kandi gukoreshwa nk'igikoresho cyo gufata ibinini n'udupira, yongera imbaraga z'imiti.
3.3. Inganda z'ibiribwa
Nk'inyongeramusaruro ku biribwa, EC ishobora gukoreshwa nk'ikintu kirwanya gufatana cyangwa ikintu kivangavanga mu shokora, bombo, n'ibiribwa bitwikiriwe, bikanoza uburyohe n'urumuri rw'ubuso mu gihe inatanga urwego runaka rwo kwirinda ubushuhe.
3.4. Izindi porogaramu z'inganda
EC ishobora gukoreshwa nk'ikintu gihagarika, kole, n'ibikoresho birinda firime mu gucukura peteroli, ibikoresho by'ikoranabuhanga, n'inganda zicapa, bigaragaza ko ikoreshwa neza cyane.
4. Amabwiriza yo Kwirinda Gukoresha
4.1. Guhitamo ibintu bishongesha
Kubera ko EC idashonga mu mazi, hagomba gutoranywa uburyo bwo gushonga bw’umwimerere bukwiye kugira ngo bushonge neza kugira ngo bushobore gukwirakwira neza kandi bukore neza.
4.2. Ubushyuhe n'Ububiko
EC igomba kubikwa kure y'ubushuhe bwinshi kugira ngo hirindwe ko ifu iterana. Igomba kandi kubikwa kure y'inkongi z'umuriro n'ubushyuhe bwinshi kugira ngo igumane ubusugire.
4.3. Guhuza n'izindi nyongeramusaruro
Mu gihe cyo gushushanya imvange, hagomba kwitabwaho uburyo EC ihura na resins, fillers, na pigments kugira ngo hirindwe ko byagira ingaruka ku gushonga no ku miterere ya rheological.
EC, hamwe n’ubushobozi bwayo bwiza bwo gukurura, gukora filime, kurekura no guhagarika, igira uruhare runini mu gusiga, imiti, ibiryo, n’izindi nganda. Mu guhindura uburemere bwayo bwa molekile n’urwego rwo gusimbuza etoxylation, EC ishobora guhinduka mu buryo bworoshye kugira ngo ihuze n’ibisabwa bitandukanye, bigatuma iba ibikoresho by’ingenzi bya polymer mu nganda zigezweho z’imiti n’imiti. Mu gihe kizaza, hamwe n’iterambere ry’ibinyabutabire by’icyatsi kibisi n’ibikoresho bikora neza, ubushobozi bwo gukoresha EC buzarushaho kwaguka.
