Cellulose ether ni ibintu byinshi byabonye ibisabwa mubikorwa bitandukanye, uhereye mubwubatsi na farumasi kugeza ibiryo na cosmetike. Iyi ngingo igamije gutanga intangiriro ya selile ya ether, kuganira kumiterere yayo, imikoreshereze, nibyiza.

Cellulose etherni ijambo rusange kubintu bitandukanye biva muri selile isanzwe (ipamba itunganijwe neza hamwe nimbuto zimbaho, nibindi) binyuze muri etherification. Nibicuruzwa byakozwe no gusimbuza igice cyangwa byuzuye gusimbuza hydroxyl mumatsinda ya selile ya macromolecules na matsinda ya ether, kandi ni inkomoko yo hasi ya selile. Nyuma ya etherification, selile irashobora gushonga mumazi, kuvanga alkali ibisubizo, hamwe na solge organic, kandi ifite imiterere ya termoplastique. Hariho ubwoko butandukanye bwa ethers ya selile, ikoreshwa cyane mubikorwa nkubwubatsi, sima, ibifuniko, imiti, ibiryo, peteroli, imiti ya buri munsi, imyenda, gukora impapuro, nibikoresho bya elegitoroniki. Ukurikije umubare wabasimbuye, irashobora kugabanywamo ether imwe hamwe na ethers ivanze, kandi ukurikije ionisiyoneri, irashobora kugabanywa muri etion ya selile selile na ether selile. Kugeza ubu, uburyo bwo gukora ionic selulose ether ionic ibicuruzwa birakuze, byoroshye kubyara umusaruro, kandi igiciro ni gito. Inzitizi yinganda ni nkeya, kandi ikoreshwa cyane mubice byongeweho ibiryo, inyongeramusaruro, inganda za chimique ya buri munsi, nibindi nibicuruzwa nyamukuru bikorerwa kumasoko.ifu ya polymer isubirwamo

Kugeza ubu, inzira nyamukuruselile ethersku isi harimo CMC, HPMC, MC, HEC, n'ibindi. Muri byo, CMC ifite umusaruro mwinshi, ikaba hafi kimwe cya kabiri cy'umusaruro ku isi, mu gihe HPMC na MC bangana na 33% by'ibikenewe ku isi, naho HEC ikaba ifite hafi 13% by'isoko ry'isi. Imikoreshereze yingenzi ikoreshwa rya Carboxymethyl selulose (CMC) ni detergent, bingana na 22% byamasoko yo hasi. Ibindi bicuruzwa bikoreshwa cyane mubikoresho byubaka, ibiryo nubuvuzi.selile ether
