Selilulosi asetati ni ibikoresho bifite uburyo bwinshi bwo gukoresha. Mu nganda z'itabi, cellulose acetate ikururwa ni yo mashini y'ibanze ikoreshwa mu kuyungurura itabi bitewe n'imikorere yayo myiza yo kuyungurura. Ikoreshwa kandi mu nganda za filime na pulasitiki mu gukora filime z'amafoto, amafoto y'ibice by'indorerwamo, n'ibikoresho byo gufata. Byongeye kandi, cellulose acetate ikoreshwa nk'ibikoresho by'ingenzi mu kuyungurura, harimo n'amafoto y'ibice by'indorerwamo n'ibintu bihindura imiterere y'ibice, bitewe n'uburyo ibasha kwinjira no guhitamo neza. Kubera ko ibora kandi ikanahinduka, cellulose acetate ikomeje kugira uruhare runini mu nganda gakondo ndetse no mu bikorwa bigezweho byo kubungabunga ibidukikije.
Uburyo bwo kuyungurura acetate ya selulosi
1. Gutegura no gushyira acetike mu bikoresho fatizo
Igikorwa gitangirana naimpumuro y'ibitiselulose, isukurwa kugira ngo ikureho lignin, hemicellulose, n'indi myanda. Selulose isukuye isubizwamoaside asetiki, aside aside, nakatalisitigukora esters za acetate za cellulose. Mu kugenzura urwego rw'isimbuza, ibyiciro bitandukanye nka diacetate cyangwa triacetate birashobora kuboneka.
2. Gutegura umuti wo gusukura no kuzunguza
Nyuma yo gukora acetylation, uruvange rw'ibisubizo rurahinduka, hanyuma ibyavuyemo bigakurwaho. Acetate ya cellulose iragezwa, yumishwa, hanyuma igashonga muacetone cyangwa acetone – uruvange rw'amazigukora igisubizo cyo kuzunguruka kimwe. Muri iki cyiciro, igisubizo kiranyuramokuyungururagukuraho uduce duto na jeli bitarashongeshwa, bigamije gutuma habaho ubwumvikane n'ubudahinduka.
3. Gutunganya no kurangiza fibre
Umuti wo kuzunguza utunganywa hakoreshejweuburyo bwo kuzunguza byumye, aho isohoka binyuze mu migozi ihinduka imigozi uko umushongi ugenda ushira. Imigozi irakusanywa, ikaramburwa, hanyuma igakorwamo ubudodo bukomeza gukururwa. Nyuma yo kuvura nko kurambura, gufunga, cyangwa kurangiza, ikoreshwa kugira ngo yongere imiterere ya fibre, bigatuma ikoreshwa muitabiakayunguruzo, imyenda, n'imyenda yihariye.
Urupapuro rw'urufunguzo rwa Great Filtration Filtration
Impapuro zo gushungura za SCY Series
Iyi mpapuro iyungurura, hamwe n’imiterere yayo ya selulosi na resini ya cationic, ifite akamaro kanini mu kuyungurura imiti ya selulosi. Itanga imbaraga nyinshi mu ikoranabuhanga, ikagira imiterere ihamye, kandi ikavanaho umwanda mu buryo bwizewe. Ingano nto ya epoxy resin ya polyamide (<1.5%) ituma habaho guhuza no kurinda umutekano mu gutunganya selulosi, bigafasha gukuraho uduce duto, gel, n’imyanda idashonga mu gihe ikomeza kugumana ubuziranenge bw’imiti no kubahiriza amahame y’umutekano w’ibiribwa n’imiti.
Ibyiza
Ikoreshwa neza mu kuyungurura– Ikuraho neza uduce duto, gel, n'imyanda idashonga mu bisubizo bya acetate ya cellulose.
Imbaraga zikomeye za mekanike– Ingufu zo guturika ≥200 kPa zituma habaho kuramba no gukora neza mu gihe cy'umuvuduko.
BihorahoUbwinshi bw'amabara– Ingufu zigenzurwa zo mu kirere (25–35 L/㎡·s) zitanga umusaruro wizewe kandi zigatanga ibisubizo bimwe ku buryo bumwe.
Umwanzuro
Asetate ya selulosi ni igikoresho cy'ingenzi gikoreshwa mu byuma biyungurura, filime, pulasitiki, n'ibice by'umubiri, gihabwa agaciro kubera imikorere yacyo no kubora kwabyo. Mu gihe cyo gukora, kuyungurura neza ni ngombwa kugira ngo habeho ubuziranenge n'ubuziranenge.
