Ubumenyi ku bijyanye na Hydroxyethyl Cellulose (HEC CAS:9004-62-0)

Inyuguti:Hydroxyethyl Cellulose (HEC CAS:9004-62-0) ni ifu y'umweru cyangwa umuhondo idafite impumuro, idafite impumuro, kandi itemba byoroshye. Irashonga haba mu mazi akonje no mu mazi ashyushye, ariko muri rusange ntishongera mu bintu byinshi biva mu binyabutabire. Agaciro ka pH gahinduka gato hagati ya 2-12, ariko ubukana buragabanuka birenze urwo rugero.

Agaciro:Hydroxyethyl Cellulose (HEC CAS:9004-62-0) ni imashini ikoreshwa cyane mu gukurura irangi ry’amazi rishingiye kuri eteri ishingiye ku mazi. Ni imvange idafite ionic ishobora gushonga mu mazi ifite ubushobozi bwo gukurura amazi, ishobora kwangirika na ogisijeni, aside na enzymes, kandi ishobora guhuzwa na Cu2+ mu gihe cy’ubushyuhe. Irahindagurika mu bushyuhe, ntigaragara nka gel mu gihe cyo gushyushya, ntigwa mu gihe cy’ubushyuhe, kandi ifite ubushobozi bwiza bwo gukora filime. Umuti wayo w’amazi ushobora gukorwamo filime zibonerana, zishobora gukorwa binyuze mu gikorwa cya cellulose ya alkaline na Chemicalbook ethylene oxide, kandi ifite imiterere yo gukurura, emulsification, adhesion, suspension, filime-forming, kubika ubushuhe, no kurinda colloid. Uruhare rw’imashini ziyongera mu imashini zishingiye ku mazi ni ukuzikurura. Kongeramo imashini ziyongera ubushuhe kuri wino byongera ubushuhe bwayo, bishobora kunoza ubuziranenge n’ubudahangarwa bw’inyi; Bitewe n’ubwiyongere bw’ubushuhe, rheology ya wino ishobora kugenzurwa mu gihe cyo gucapa; Ibara ry'umukara n'umunyururu biri muri wino ntabwo byoroshye kubigabanya, bikongera uburyo wino ishingiye ku mazi igumana ubuziranenge.

Uburyo bwo gukora：Alkali cellulose ni polymer karemano irimo amatsinda atatu ya hydroxyl kuri buri ruziga rw'ibanze rwa fibre. Itsinda rya hydroxyl rikora cyane rikora kugira ngo rikore hydroxyethyl cellulose. Shyira ipamba rito cyangwa pulp itunganyijwe muri alkali y'amazi ya 30%, hanyuma uyikuremo uyikanda nyuma y'igice cy'isaha. Kanda kugeza igihe amazi ya alkali agera kuri 1:2.8, hanyuma uyisya. Alkali cellulose ishwanyagujwe ishyirwa muri reactor, ifunze, isukurwe, kandi yuzuzwe azote. Chemicalbook isukurwa inshuro nyinshi kandi yuzuzwe azote kugira ngo isimbuze umwuka wose uri muri reactor. Kanda mu mazi ya ethylene oxide yakonjeshejwe mbere, shyira amazi akonje mu ikoti rya reactor, hanyuma ugenzure ubushyuhe bwa reaction kugeza kuri 25 ℃ mu gihe cy'amasaha 2 kugira ngo ubone product ya hydroxyethyl cellulose ishaje. Product ishaje yogejwe na alcool, ivangwa na aside asetiki kugeza kuri pH 4-6, hanyuma ihuzwe na glyoxal kugira ngo ishaje. Hanyuma oza n'amazi, centrifuge, ongera amazi, wumishe, hanyuma usya kugira ngo ubone hydroxyethyl cellulose.
