Selulose ya ethyl (EC)ni eteri ya cellulose itari ionic ikomoka kuri cellulose karemano binyuze mu buryo bwa ethylation. Bitewe n'ubushobozi bwayo bwiza bwo gukora filime, kudahinduka k'ubushyuhe, no kudakora neza kwa shimi, ikoreshwa cyane mu gusiga irangi, wino, imiti, ibikoresho by'ikoranabuhanga, n'izindi nganda. Ariko, ethyl cellulose gakondo ishongeshejwe mu bintu bishongesha ibinyabuzima itera ibibazo nko gushya, impungenge ku bidukikije, n'ibiciro biri hejuru by'imikorere. Kugira ngo ibyo bibazo bikemuke, hakozwe dispersions za ethyl cellulose zikomoka ku mazi (AECDs).
1. Ibisobanuro n'ibiranga ikwirakwizwa rya selulosi y'amazi ya ethyl
Uduce duto twa ethyl cellulose two mu mazi ni ibikoresho bikora uburyo buhamye bwo gukwirakwiza mu mazi hakoreshejwe uburyo bwo gukwirakwiza, gukwirakwiza, cyangwa guhindura. Ibintu by'ingenzi bigize ibyo bintu birimo:
Bishingiye ku mazi kandi bitangiza ibidukikije: Birinda gukoresha imiti gakondo ihumanya ikirere, byujuje ibisabwa n’inganda zikora imiti igezweho irinda ibidukikije ndetse n’inganda zikora imiti ihumanya ibidukikije.
Ubudahangarwa bwinshi: Uduce twa ethyl cellulose mu gukwirakwira dukwirakwira kimwe mu gice cy'amazi, bigaragaza ubudahangarwa bwiza bwo kubika no kurwanya guhindagurika cyangwa kwivanga.
Ubucucike Bugenzurwa: Mu guhindura urwego rw'ubusimbuza, uburemere bwa molekile, n'uburyo ethyl cellulose ikwirakwizwa, amazi akwirakwizwa afite ubucucike butandukanye ashobora kuboneka kugira ngo yuzuze ibisabwa bitandukanye.
Imiterere myiza yo gukora firime: Nyuma yo kuva amazi mu gihe cyo kumisha, ethyl cellulose ikora firime imwe, ihoraho kandi ifite imbaraga nziza za mashini kandi ikagira ubuziranenge buhamye.
Ikorana neza: Ishobora kuvangwa n'ibindi bintu bitandukanye, resins, irangi, n'ibindi byuzuza, bigatuma ikoreshwa cyane mu irangi, wino, n'ibindi bikoresho bikora neza.
2. Uburyo bwo gutegura
2.1. Uburyo bwo gukwirakwiza Emulsion
Selulose ya ethyl ishongeshwa mu kintu cy’umwimerere hanyuma, hakoreshejwe emulsifier no gukurura vuba, igakora emulsion dispersion mu mazi. Hanyuma icyo kintu cy’umwimerere gikurwaho kugira ngo haboneke ethyl cellulose dispersion y’amazi. Ubu buryo butanga dispersion ifite utunyangingo duto kandi ihamye neza.
2.2. Uburyo bwo gukwirakwiza imashini
Ifu ya ethyl cellulose ikwirakwizwa mu buryo butaziguye mu buryo bw'amazi binyuze mu gukata cyangwa gusya vuba. Hanyuma hongerwamo imashini igabanya ubushyuhe cyangwa igabanya ubushyuhe kugira ngo sisitemu ihamye. Ubu buryo burakwiriye mu gutegura imashini zigabanya ubushyuhe mu mazi.
2.3. Uburyo bwo guhindura imiti
Selulose ya ethyl ihindurwa hakoreshejwe imiti binyuze mu gukurura ibice bya karubokisilasiyo cyangwa hydroxylation kugira ngo ishyiremo amatsinda y’amazi ku buso bwayo, bigatuma ikora ikwirakwira mu mazi mu buryo busanzwe. Ubu buryo bukunze gukoreshwa mu gutwikira ibintu cyangwa mu buryo bw’imiti.
3. Imikoreshereze ya Ethyl Cellulose Aqueous Dispersions
3.1. Udupira dushingiye ku mazi
Nk’ibikomeza ubushyuhe, ibifasha mu gukora filime, cyangwa ibifunga, ethyl cellulose aqueous dispersions ishobora kunoza uburyo bwo gusiga, gufatana, no kudashwanyagurika mu gihe ikagabanya ikoreshwa ry’ibintu bihumanya ikirere no kongera imikorere y’ibidukikije.
3.2. Wino ishingiye ku mazi
Mu irangi ryo gucapa, irangi rya ethyl cellulose rishobora kunoza uburyo ringana n'ibara, mu gihe rinanongera umuvuduko wo kumisha no kudakoresha amazi. Rikwiriye gucapa mu gupakira, gucapa mu buryo bwa flexographic, n'ibindi bikorwa.
3.3. Imiti n'ibiribwa
Nk’ibice birekura imiti cyangwa ibiryo bitwikiriwe n’imiti, ibisigazwa bya ethyl cellulose y’amazi birinda ingaruka mbi z’imiti isigaye mu gihe bitanga umusaruro ugenzurwa.
3.4. Ibikoresho by'ikoranabuhanga n'amabara akoreshwa mu gusiga
Mu bikoresho byo gupfunyikamo by’ikoranabuhanga no muri firime zikora, ethyl cellulose aqueous dispersions ishobora gukora nk'ibice bitanga firime, bigatanga imiterere myiza ya mekanike no kudahungabana k'ubushyuhe. Bishobora kandi guhuzwa byoroshye na nanomaterials kugira ngo bikore firime zibonerana cyangwa ziyobora.
4. Uburyo bwo kwirinda n'uburyo iterambere rigenda
Kugenzura Ubudahangarwa: Inzira zo gukwirakwira mu mazi zishobora kwangirika n'ubushyuhe, pH, na electrolytes. Kubwibyo, hagomba gutoranywa imashini zikwirakwira n'uburyo bwo kubika hashingiwe ku ikoreshwa ryazo.
Umusaruro wo Gutunganya Filimi: Guhumeka cyane kw'amazi bishobora gutera gucika kw'igitambaro. Ubwiza bw'igitambaro bugomba kunozwa binyuze mu kongeramo cyangwa kunoza uburyo bwo gukora.
Icyatsi kibisi n'imikorere myiza: Mu gihe kizaza, ethyl cellulose aqueous dispersions izakura ikagera ku bintu bikomeye, VOC nke, no gukora neza (nk'uko umuriro udashira, kudakoresha amazi, no gutwara amashanyarazi) kugira ngo ihuze n'ibikenewe mu nganda no mu buvuzi.
Seliruru za ethylIbikoresho bikwirakwiza amazi ni ibikoresho bitagira ingaruka ku bidukikije, bifite imikorere myiza kandi bikoresha amazi, bihuza imiterere myiza ya ethyl cellulose ikora filimi n'akamaro k'icyatsi kibisi k'ibikoresho bikoresha amazi. Ntabwo ari ingirakamaro gusa mu nganda gakondo nko gusiga irangi, wino, n'imiti, ahubwo binagaragaza ubushobozi mu nzego zikiri kuzamuka nko gusiga irangi ry'ikoranabuhanga n'ibikoresho bikoresha imikorere. Hamwe no gukwirakwiza ibitekerezo bya shimi ku cyatsi kibisi no guteza imbere ikoranabuhanga ry'ibikoresho bikoresha amazi, gusiga irangi ry'amazi rya ethyl cellulose bizaba icyerekezo cy'ingenzi mu iterambere ry'ibikoresho by'ejo hazaza.
