Cellulose ether is a general izwi renhevedzero zvigadzirwa zvakagadzirwa nekuita kweAlkali cellulose uye kuenzura mumiririri pasi pemamwe mamiriro ezvinhu. Alkali cellulose inotsiviwa nekusiyana kwekunyengedza vamiririri kuti vawane akasiyana cellulose eter. Maererano neIonization Progriynices of Sdzs, Cellulose eterities inogovaniswa muzvikamu zviviri: Ionic (senge carboxyMethyl cellemelle) uye isiri-ionic (yakadai se methyl cellose). Maererano nerudzi rwetsiva, cellulose ether inogona kukamurwa muMonether (senge methyl cellulose) uye yakasanganiswa ethyropropropyl methyl cellelose). Maererano nekumwe salubility, inogona kukamurwa kuita zvemvura (senge hydroxeksyl cell-solulose celly-solulose mheremello cellylose.
Pashure pokunge cellulose ether mumvura iri mumvura, kugoverwa kwekupariswa kwemvura muhurongwa hwesangano, uye cellulose ether, seyakagadzika "sosi yakasimba uye inovadarika pane iyo yekunze. Gadzira firimu rinopenya, ita kuti hurongwa hwakagadzikana, uye zvakare kugadzirisa iyo fluidity yemutya panguva yekusanganisa maitiro uye kusimba kwekuvaka.
Nekuda kweiyo its oga molecular chimiro, cellulose gadziriso yekugadzirisa kuti mvura iri nyore kurasikirwa, uye zvishoma nezvishoma inoiburitsa kwenguva yakareba yenguva, kuendesa dhuma nekuchengetwa kwakanaka kwemvura uye nekudzoreredza mvura.
Kuzvimiririra kwepasi siment frand, ine low viscosity hydroxyprosyl methylcellose ether. Sezvo ivhu rese raizokwezverwa nemusikirwo nekupindira nevashandi vekuvaka, vachienzaniswa neyekutanga zvinyorwa zvekushandisa, kubhururuka uye kumhanya kwekuvaka kwakavandudzwa zvikuru. Iyo yekuzvimiririra yakaoma kusanganisa nguva inotora mukana wekuchengeta kwakanaka kwemvura kwehydroxpropropropylculcellose. Sezvo kuzvimiririra kunoda kuti dhiraivhi rakakurudzirwa rinogona otomatiki pasi, zvinhu zvemvura zvakakura. Mushure mekuwedzera HPMC, ichadzora pasi kuchengetedza kwemvura haisi pachena, iyo inoita kuti nzvimbo ive nesimba rapfuura mushure mekuoma, uye kuderera kuri diki, rinoderedza marara. Kuwedzerwa kweHPMC kunopawo viscosity, iyo inogona kushandiswa seyenti-yedhiramu rubatsiro, kusimudzira fluidity uye kupokana, uye kugadzirisa kugona kwekuvhara pasi.
Yakanaka cellulose ine fluffy inooneka mamiriro uye diki yakakura density; Yakachena HPMC ine machena machena, zvinhu zvakawandisa zvinoshandiswa mukugadzirwa zvakachena, kuita kwakanyatsogadzirwa uye kusachena, mhinduro yemvura iri pachena, iyo inobuda mwenje yakakwira, uye hapana Ammonia, mhizha uye madhare. Ravira, fibrous pasi pemicroscope kana girazi rekukudza.
