Magaca kiimikada,Cellulose-ka Hydroxypropyl Methyl (HPMC), Hydroxyethyl Methyl Cellulose (HEMC),Sodium Carboxymethyl cellulose (CMC), Hydroxyethyl cellulose (HEC), HEC oo si dabiici ah wax looga beddelay (HMHEC),Methyl cellulose (MC),Methyl hydroxyethyl cellulose (MHEC), Ethyl hydroxyethyl cellulose (EHEC), Ethers cellulose ah oo si Hydrophobic ah wax looga beddelay (EHEC, HM-EHEC).
Ether-yada Cellulose waxaa loo qaabeeyey iyada oo loo marayo isbeddello kiimiko ah oo cellulose ah oo leh kiimikooyin kale. Ether-yada Cellulose waa polymers-yo aan ionic ahayn oo biyaha ku milma oo ku salaysan cellulose-ka polymer-ka ee ugu badan ee dabiiciga ah. In ka badan 70 sano, alaabadani waxay door muhiim ah ka ciyaareen codsiyadan, laga bilaabo badeecadaha naqshadeynta, dhoobada iyo rinjiga ilaa cuntada, qurxinta iyo daawooyinka. Ether-yada Cellulose waxaa loo isticmaalaa kiimikooyin shaqeynaya iyo kuwa rheological ah iyo waxqabad ahaan sida hay'adaha dhumucda, emulsifiers, colloids difaac, xasiliyayaal iyo sidoo kale haynta biyaha.
Dhismaha, cellulose ethers waxay u adeegaan sida dhumuc-dheereyaal, xidheyaal, kuwa sameeya sawirrada iyo hay'adaha dayactirka aan la qeexin ee biyaha, caawiyeyaasha joojinta, surfactants, saliidaha, kolloids-ka ilaalinta iyo emulsifiers. Intaa waxaa dheer, daawooyinka biyaha ee jelka gaarka ah ee cellulose ethers ee kuleylka, guri gaar ah oo qaata boos muhiim ah oo ku jira barnaamijyo kala duwan. Isku darka sifooyinkan qiimaha leh runtii kuma jiraan ku dhawaad polymer kasta oo kale oo milma h2o.
Xaqiiqda ah in sifooyin aan tiro lahayn oo faa'iido leh ay isku mar jiraan oo inta badan ay isku darsamaan waxay noqon kartaa faa'iido dhaqaale oo weyn. Barnaamijyo badan, maaddooyin badan ayaa looga baahan doonaa inay qabtaan shaqo la mid ah tan ay sameeyeen badeecad gaar ah oo ah cellulose ether. Intaa waxaa dheer, cellulose ethers aad bay u guuleystaan, badanaa waxay keenaan waxtarka ugu fiican marka la eego polymer-yada kale ee biyaha lagu milo.

Cellulose-ka AnxinKu adkeyso aragtida horumarinta 'Heerka sare ee aadka u fiican, Waxqabadka, Daacadnimada iyo habka shaqada ee hoos u dhaca' si uu kuugu keeno bixiye weyn oo habayn ah oo loogu talagalay Iibinta Kulul ee Shiinaha Cellulose Ether oo leh Horumarin Sare-Iska-caabbinta, Tayada sare ee sare, heerarka tartanka, keenista degdegga ah iyo caawimaad la isku halleyn karo ayaa la damaanad qaaday Fadlan noo oggolow inaan ogaano baahidaada tirada ee qayb kasta oo cabbir ah si aan si fudud kuugu wargelin karno si waafaqsan.
Iibinta kulul ee loogu talagalay Shiinaha cellulose ethers, Si aan u sii wadno booska hoggaamineed ee warshadeenna, waligeen ma joojinno inaan ka hor tagno xaddidaadda dhinac kasta si aan u abuurno xalalka ugu habboon. Jidkiisa, waxaan ku kobcin karnaa qaab nololeedkeenna oo aan kor u qaadi karnaa jawi nololeed oo wanaagsan oo loogu talagalay bulshada adduunka.
