Cellulose etherishoko remubatanidzwa rezvakasiyana-siyana zvakatorwa kubva kune zvakasikwa cellulose (yakanatswa donje uye huni pulp, nezvimwewo) kuburikidza ne etherification.Icho chigadzirwa chinoumbwa nechikamu kana chakazara kutsiva mapoka ehydroxyl mu cellulose macromolecules nemapoka ether, uye inodzika yakadzika kubva kune cellulose.Mushure me etherification, cellulose inonyungudika mumvura, inonyungudutsa alkali solutions, uye organic solvents, uye ine thermoplastic properties.Kune akawanda akasiyana-siyana e-cellulose ethers, anoshandiswa zvakanyanya mumaindasitiri akadai sekuvaka, simende, machira, mishonga yemishonga, chikafu, peturu, makemikari ezuva nezuva, machira, kugadzira mapepa, uye zvigadzirwa zvemagetsi.Zvinoenderana nehuwandu hwezvinotsiva, inogona kupatsanurwa kuita ether imwe uye yakasanganiswa ether, uye zvinoenderana neionization, inogona kupatsanurwa kuita ionic cellulose ethers uye isiri ionic cellulose ethers.Parizvino, kugadzirwa kweionic cellulose ether ionic zvigadzirwa zvakura, zviri nyore kugadzira, uye mutengo wakaderera.Indasitiri chipingamupinyi chakaderera, uye inonyanya kushandiswa muminda yezvikafu zvinowedzera, machira ekuwedzera, zuva nezuva indasitiri yemakemikari, nezvimwe. Ndicho chigadzirwa chikuru chinogadzirwa mumusika.
Parizvino, mainstreamcellulose ethersMunyika mune CMC, HPMC, MC, HEC, etc. Pakati pavo, CMC ine kugadzirwa kukuru, inoverengera inenge hafu yekugadzirwa kwepasi rose, nepo HPMC neMC vachitora chikamu che33% chezvinodiwa pasi rose, uye HEC inoverengera. inenge 13% yemusika wepasi rose.Kunyanya kukosha kwekupedzisira kushandiswa kweCarboxymethyl cellulose (CMC) ndeye detergent, inoverengera 22% yemusika wepasi unodikanwa.Zvimwe zvigadzirwa zvinonyanya kushandiswa mukuvaka, chikafu uye mishonga minda.
