Cellulose ether

Cellulose etheramapangidwa kuchokera ku celluluse kudzera munthawi yowunikira imodzi kapena zingapo zokopa ndi zopukutira zouma. Malinga ndi mitundu yosiyanasiyana ya mankhwala a ether, cellulose eders imatha kugawidwa mu Anionic, CARTIC komanso osagwirizana nawo. Ma celluose a Ionic engers amaphatikizansoCarboxymethyl cellulose ether (cmc); cellulose yopanda inic edzonda imaphatikizaponsoMethyl cellulose ether (MC),hydroxypypyl methyl cellulose ether (hpmc)ndi hydroxyethyl cellulose ether.Chlorine ether (hc)ndi zina zotero. Mafuta osakhala a Ionic amagawidwa kukhala madzi osungunuka ndi mafuta a mafuta, ndipo osasungunuka madzi osungunuka amagwiritsidwa ntchito makamaka pazopanga matope. Pamaso pa calcium aons, Ionic cellulose ether ndi osakhazikika, kotero sizimagwiritsidwa ntchito pokhapokha matope owuma omwe amagwiritsa ntchito simenti, malo ogona, monga zida zamitengo. Cellose yopanda madzi yam'madzi imagwiritsidwa ntchito kwambiri makampani omanga zida chifukwa cha kukhazikika kwawo komanso kusungidwa kwamadzi.

Mankhwala opangira cellulose ether

Vesi iliyonse ya ether ili ndi kapangidwe koyambira kwa cellulose - lembocrogluce mawonekedwe. Mukamapanga ma cellulose ether, chiberekero cha cellulose chimakhala chotenthetsera mu yankho la alkalinine, kenako amathandizidwa ndi wothandizila. Chogulitsa cha fibrous chizolowezi chimatsukidwa ndikutsukidwa kuti apange ufa wofanana ndi uwu wabwino.

Pazopanga za MC, methyl chloride imagwiritsidwa ntchito ngati wothandizira; Kuphatikiza pa methyl chloride, ma propyle oxide amagwiritsidwanso ntchito kupeza magulu oyang'anira ma hydroxypyl popanga hpmc. Cellulose yosiyanasiyana imakhala ndi methyl komanso hydroxypropyl kulower, zomwe zimakhudza kuteteza kwa organic.
