I-cellulose etheryitemu elihlangene lezinhlobonhlobo zokuphuma kokunye okutholakala ku-cellulose yemvelo (ukotini ocolisisiwe kanye ne-pulp yokhuni, njll.) ngokusebenzisa i-etherification.Kungumkhiqizo owenziwe ngokushintshwa okuyingxenye noma okuphelele kwamaqembu e-hydroxyl kuma-cellulose macromolecules ngamaqembu e-ether, futhi iphuma ezansi nomfula ku-cellulose.Ngemuva kokufakwa kwe-etherification, i-cellulose iyancibilika emanzini, ixube izixazululo ze-alkali, nezinyibilikisi eziphilayo, futhi inezici ze-thermoplastic.Kunezinhlobonhlobo eziningi ze-cellulose ethers, ezisetshenziswa kakhulu ezimbonini ezifana nezokwakha, usimende, okokugqoka, imithi, ukudla, i-petroleum, amakhemikhali ansuku zonke, izindwangu, ukwenza amaphepha, kanye nezingxenye ze-electronic.Ngokuya ngenani lama-substitutes, ingahlukaniswa ibe ama-ether awodwa kanye nama-ether axubile, futhi ngokuya nge-ionization, ingahlukaniswa ngama-ether e-ionic cellulose nama-non-ionic cellulose ethers.Njengamanje, inqubo yokukhiqiza imikhiqizo ye-ionic cellulose ether ionic isivuthiwe, kulula ukuyikhiqiza, futhi izindleko ziphansi uma kuqhathaniswa.Umgoqo wemboni uphansi kakhulu, futhi usetshenziswa kakhulu emikhakheni yezithako zokudla, izithasiselo zendwangu, imboni yamakhemikhali yansuku zonke, njll. Iwumkhiqizo oyinhloko okhiqizwa emakethe.
Njengamanje, i-mainstreami-cellulose ethersemhlabeni kukhona i-CMC, i-HPMC, i-MC, i-HEC, njll. Phakathi kwazo, i-CMC inomkhiqizo omkhulu kunayo yonke, ebalwa cishe ingxenye yomkhiqizo womhlaba wonke, kuyilapho i-HPMC ne-MC benza cishe u-33% wesidingo somhlaba wonke, futhi i-HEC ilandisa nge- cishe u-13% wezimakethe zomhlaba.Ukusetshenziswa kokugcina okubaluleke kakhulu kwe-Carboxymethyl cellulose (CMC) okokuhlanza, okubalelwa ku-22% wesidingo semakethe esezansi nomfula.Eminye imikhiqizo isetshenziswa kakhulu ezindaweni zokwakha, ukudla kanye nemithi.
