Cellulose ether ni selile isanzwe (ipamba itunganijwe neza hamwe nigiti cyimbaho, nibindi) nkibikoresho fatizo, nyuma ya etherifisation yinkomoko itandukanye, ni selile ya macromolecule hydroxyl hydrogène ya selile ya ether igice cyangwa igasimburwa rwose nyuma yo gukora ibicuruzwa, nibikomoka kumanuka. ya selile.Cellulose irashobora gushonga mumazi, kuyungurura umuti wa alkali hamwe na solvent organic nyuma ya etherification, kandi ifite imiterere ya thermoplastique.Ubwoko bwa selulose ether, bukoreshwa cyane mubwubatsi, sima, gutwikira, ubuvuzi, ibiryo, peteroli, imiti ya buri munsi, imyenda, impapuro nibikoresho bya elegitoronike nizindi nganda.Ukurikije umubare wabasimbuye urashobora kugabanywa muri ether imwe hamwe na ether ivanze, ukurikije ionisiyoneri ishobora kugabanywa muri ionic selulose ether na ether ionic selulose ether.Kugeza ubu, ionic selulose ether ionic progaramu yumusaruro urakuze, biroroshye gukora kandi ugereranije nigiciro gito, inzitizi zinganda ugereranije, zikoreshwa cyane mubyongeweho ibiryo, inyongeramusaruro, imiti ya buri munsi nizindi nzego, nibicuruzwa nyamukuru ku isoko.
Kugeza ubu, isi yose yingenzi ya selulose ether ni CMC, HPMC, MC, HEC nizindi nyinshi, umusaruro wa CMC niwo munini, ugera hafi kimwe cya kabiri cy’ibicuruzwa biva ku isi, mu gihe HPMC na MC byombi bingana na 33% by’ibikenewe ku isi, HEC ifite hafi 13% yisoko ryisi.Ikintu cyingenzi cyanyuma-ikoreshwa rya carboxymethyl selulose (CMC) ni detergent, bingana na 22% byamasoko yo hasi, kandi nibindi bicuruzwa bikoreshwa cyane mubikoresho byubaka, ibiryo nubuvuzi.
Ii.Porogaramu yo hasi
Mu bihe byashize, kubera iterambere rike ry’iterambere rya selile ya selile mu miti ya buri munsi, ubuvuzi, ibiryo, ibifuniko ndetse n’indi mirima yo mu Bushinwa, icyifuzo cya ether ya selile mu Bushinwa cyibanze ahanini mu bijyanye n’ibikoresho byubaka, kugeza uyu munsi, inyubako inganda zikoresha ibikoresho biracyafite 33% byifuzo bya selile ether mubushinwa.Kimwe na selile yo mu Bushinwa ya selile mu bijyanye n’ibikoresho byo kubaka isabwa ryuzuye, mu miti ya buri munsi, imiti, ibiryo, gutwikira hamwe n’ibindi bisabwa biriyongera cyane hamwe n’iterambere ry’ikoranabuhanga.Kurugero, mumyaka yashize, capsule yibihingwa hamwe na selile ya ether nkibikoresho nyamukuru, kimwe nibicuruzwa bivuka bikozwe mu nyama zakozwe na selile na ether ya selile bifite ibyifuzo byinshi hamwe niterambere ryikura.
Mu rwego rwibikoresho byubwubatsi, kurugero, ether ya selulose ifite umubyimba, kubika amazi, korohereza buhoro nibindi biranga ibintu byiza cyane, bityo ibikoresho byo kubaka urwego rwa selulose ether ikoreshwa cyane mugutezimbere imikorere yibikoresho byubaka birimo minisiteri ivanze (harimo na wet ivanze na minisiteri ivanze), gukora PVC resin, gukora irangi rya latex, putty, nibindi .. Bitewe niterambere ryurwego rwimijyi mubushinwa, iterambere ryihuse ryinganda zubaka, urwego rwimashini zubaka rukomeje gutera imbere, n'abaguzi basaba ibidukikije kubikoresho byubwubatsi bigenda byiyongera, biganisha ku gukenera ether ya selile idafite ionic mubijyanye nibikoresho byubaka.Mu gihe cy’imyaka 13 y’imyaka itanu, Ubushinwa bwihutishije kuvugurura uduce twarangiritse n’amazu yangiritse mu mijyi, kandi bushimangira iyubakwa ry’ibikorwa remezo byo mu mijyi, harimo kwihutisha ivugurura ry’ahantu hacuramye n’imidugudu mu mijyi, no guteza imbere ivugurura ryuzuye. ahantu hatuwe hambere no kuvugurura amazu ashaje yangiritse hamwe namazu atuzuye.Mu gice cya mbere cya 2021, hatangijwe metero kare miliyoni 755.15 za metero kare yo guturamo, hejuru ya 5.5%.Ubuso bwuzuye bwamazu ni metero kare 364.81, hejuru ya 25.7%.Kwiyongera k'ahantu huzuye k'umutungo utimukanwa bizatera icyifuzo gikenewe mubijyanye na selile yubaka selile.
3. Uburyo bwo guhatanira isoko
Ubushinwa nigihugu cy’umusemburo wa selile ku isi, kuri ubu icyiciro cyibikoresho byo mu rugo icyiciro cya selulose ether cyageze ahanini mubaturage, Anxin Chemistry iyoboye inganda mu bijyanye na selile ether, abandi bakora inganda zikomeye zo murugo nabo barimo Kima Chemical nibindi. ibiryo byo mu bwoko bwa selile ether kuri ubu ni cyane cyane Reta zunzubumwe za Amerika Dow, Ashland, Ubuyapani shinetsu, Koreya yepfo Lotte hamwe n’abandi bonyine bo mu mahanga.Kuri KuriUbuvuzi bwa Anxintoni nyinshi zirenga ibihumbi icumi byinganda, toni ibihumbi nibihumbi bitari ionic selulose ether yinganda ziciriritse, ibyinshi muribi bigo bito bitanga ibikoresho bisanzwe byubaka ibikoresho byo mu rwego rwa selulose ether, kandi nta mbaraga zo gukora ibiryo byinshi byo murwego rwohejuru nibicuruzwa bya farumasi.
Bane, selile ether itumizwa no kohereza hanze
Muri 2020, kubera icyorezo cyo mu mahanga cyatumye igabanuka ry'umusaruro w’inganda z’amahanga, ibicuruzwa byo mu bwoko bwa selulose yo mu Bushinwa byoherezwa mu mahanga byagaragaje iterambere ryihuse, mu 2020 kugira ngo ibyoherezwa mu mahanga byoherezwa muri toni 77.272.Nubwo ibicuruzwa byoherezwa mu mahanga bya selile mu Bushinwa byiyongera cyane, ibicuruzwa byoherezwa mu mahanga bishingiye ahanini ku bikoresho byubaka selile, mu gihe ibicuruzwa byoherezwa mu mahanga by’ubuvuzi na selile biribwa ari bike cyane, kandi agaciro kiyongereye ku bicuruzwa byoherezwa mu mahanga ni bike.Kugeza ubu, ibicuruzwa byoherezwa mu mahanga bya selulose ether mu Bushinwa bikubye inshuro enye ibicuruzwa biva mu mahanga, ariko ibicuruzwa byoherezwa mu mahanga ntibikubye inshuro ebyiri amafaranga yatumijwe mu mahanga.Mu rwego rwibicuruzwa byohejuru byo mu rugo selileose ether yohereza ibicuruzwa hanze biracyari umwanya munini witerambere.
