Cellulose ether

Cellulose ethers rukuni ne na abubuwan da aka gyara na sinadarai, inda aka maye gurbin kungiyoyin hydroxyl (-OH) na kwayoyin cellulose tare da kungiyoyin ether (-OR). Wadannan gyare-gyare suna haɓaka kaddarorin cellulose, suna sa ya fi amfani a masana'antu daban-daban.

Cellulose Ether sun tabbatar da cewa suna da amfani da yawa na tushen polymers, neman aikace-aikace a yankunan da suka hada da abinci, kayan kulawa na sirri, sinadarai na filin mai, gine-gine, takarda, adhesives, da yadi.;

Suna da ƙima ta musamman a cikin aikace-aikacen magunguna saboda halaye waɗanda suka haɗa da yanayin canjin gilashi mai girma, babban sinadari da kwanciyar hankali na hoto, solubility, ƙarancin crystallinity, ƙarfin haɗin gwiwar hydrogen, da ƙarancin guba.;

Game da guba, ethers cellulose ba su da ainihin ikon yin ratsawa ta hanyar enterocytes na ciki kuma da yawa sun riga sun kasance cikin abubuwan da Hukumar Abinci da Magunguna ta Amurka ta amince.

Cellulose ethers sune polymers masu narkewa da ruwa wanda aka samar ta hanyar gyaran sinadarai na cellulose.;

Manyan ethers cellulose na kasuwanci sun haɗa da carboxymethylcellulose (CMC), methylcellulose (MC) da abubuwan da aka samo kamar su hydroxypropyl methylcellulose (HPMC) da hydroxyethyl methylcellulose (HEMC), hydroxyethylcellulose (HEC) da abubuwan haɓaka kamar ethyl hydroxyethylcellulose da methylcellulose hydroxyethylcellulose (MEHEC), hydroxypropyl cellulose (HPC), da ethylcellulose (EC).

Cellulose ethersaiki a matsayin stabilizers, thickeners, da danko gyare-gyare a cikin da yawa masana'antu, ciki har da abinci, Pharmaceuticals, na sirri kula kayayyakin, mai filin sinadarai, gini, takarda, adhesives, da yadi;

A cikin zaɓin aikace-aikacen, suna gasa da juna kuma tare da polymers na ruwa mai narkewa (polyvinyl barasa, polyurethane associative thickeners, polyacrylates) da kuma na halitta ruwa mai narkewa polymers (xanthan danko, carrageenan, fari wake danko).

Zaɓin zaɓi na polymer an ƙaddara ta hanyar ciniki na farashin / ayyuka, samuwa, da sauƙi na sake fasalin samfurin bisa la'akari da farashin / ayyuka.

Cellulose ether ne foda ether cellulose da aka samar da itace fiber ko mai ladabi short auduga fiber a matsayin babban albarkatun kasa, bayan sinadaran magani da kuma ta dauki etherifying jamiái kamar chlorinated ethylene, chlorinated propylene da oxidized ethylene.
