Cellulose ether is a synthetic polymer yakagadzirwa kubva kune yakasikwa cellerse kuburikidza nemakemikari kugadziridzwa. Cellulose ether ndiyo inobviswa kwemasikirwo cellulose. Iko kugadzirwa kwe cellulose ether kwakasiyana nePolythetic polymers. Yayo yakakosha zvinyorwa ndeye cellulose, iyo yakasikwa polymer yakaenzana. Nekuda kwekuva kunyanya kwechimiro chemasangano cellulose, cellulose pachayo haina kugona kuita nevamiriri evaera. Nekudaro, mushure mekurapa kwekuzvimba kwekuzvimba, iyo yakasimba maHydrogen maketani uye ngetani dzinoparadzwa, uye kuburitswa kweiyo hydroxyl boka rinova alkali alkali alkalal. Tora cellulose ether.
Zvivakwa zveCellulose anaTers vanovimba nerudzi rwevanhu, nhamba uye kugoverwa kwevatsidzike. Kugadziriswa kwe cellulose ana vana zvakare kunoenderana nerudzi rwevatsidzi, degree rekutsva, solubility uye zvinoenderana nekushandisa zvivakwa. Sekureva kwerudzi rwevatsidzi pane caomlecular cheni, inogona kugovaniswa muMonether uye yakasanganiswa ether. Isu tinowanzo shandisa mc seMonether, uye hpmc sezvisina kubatirwa ether. MetHyl Cellulose ether MC ndiyo chigadzirwa mushure meiyo hydroxyl boka pane glucose unit yemusango cellows inotsiviwa nedunhu. Icho chigadzirwa chakawanikwa nekutsiva chikamu cheiyo hydroxyl boka pane iyo unit neiyo nzira yeboka uye chimwe chikamu chine hydroxyprupropropyl group. Iyo formula yekugadzira ndeye [c6h7O2 (o) 3-mn (och2ch (och2ch (och2ch (och3) ch3]
Panyaya yekugadzirisa, inogona kukamurwa kuita ionic uye isiri-ionic. Mvura-yakashata isiri-ionic cellery ana ana ana ana inonyanya kuumbwa nenhevedzano maviri eAlkyl yeAlkyl uye hydroxielinkyl anaiters. Ionic cmc inonyanya kushandiswa mu synnthetic inodzika, machira ekudhinda uye kunyepa, chikafu uye kusaongorora kwemafuta. Non-Ionic MC, HPMC, HEMC, etc. Inonyanya kushandiswa mune zvekuvaka, mishonga yezuva nezuva, etces inoda mumiririri, STabilizer, inopararira uye firimu inogadzira mumiririri.
