Cellulose ether urugero

Cellulose etherurugero ni polymer compound ikozwe muri selile hamwe na ether imiterere. Buri mpeta ya glucose muri macromolecule ya selile irimo amatsinda atatu ya hydroxyl, itsinda ryambere rya hydroxyl kuri atome ya karubone ya gatandatu, hamwe na hydroxyl ya kabiri kuri atome ya kabiri na gatatu ya karubone. Hydrogen mu itsinda rya hydroxyl isimburwa nitsinda rya hydrocarubone kugirango ikore selile. Nibicuruzwa byo gusimbuza hydroxyl hydrogène nitsinda rya hydrocarubone muri selile ya polymer. Cellulose ni polyhydroxy polymer ivanze idashonga cyangwa ngo ishonga. Cellulose irashobora gushonga mumazi, kuyungurura umuti wa alkali hamwe na solvent organic nyuma ya etherification, kandi ifite imiterere ya thermoplastique.

Cellulose ether nijambo rusange ryuruhererekane rwibicuruzwa biterwa no kwitwara kwa alkali selulose na etherifying agent mubihe bimwe. Alkali selulose isimburwa nuburyo butandukanye bwa etherifying kugirango babone ethers zitandukanye.

Ukurikije imiterere ya ionisation yibisimburwa, urugero rwa selile ya selile irashobora kugabanywamo ionic (nka carboxymethyl selulose) hamwe na ionic (nka methyl selulose) ibyiciro bibiri.

Ukurikije ubwoko bwinsimburangingo,selile ethersurugero rushobora kugabanywamo ether imwe (nka methyl selulose) na ether ivanze (nka hydroxypropyl methyl selulose). Ukurikije solubilité, irashobora kugabanywa mumazi ashonga (nka hydroxyethyl selulose) hamwe no gukomera kwa organic (nka Ethyl selulose). Amabuye yumye yumye akoresha cyane cyane selile-solubose ya selile, ishobora kugabanywa mubwoko bwihuse kandi bigatinda gushonga nyuma yo kuvurwa hejuru.

Ibivanze bigira uruhare runini mugutezimbere imitungo ivanze yumye kandi bingana na 40% yikiguzi cyibikoresho byumye. Igice kinini cyimvange kumasoko yimbere mugihugu gitangwa nabakora mumahanga, kandi dosiye yerekana ibicuruzwa nayo itangwa nababitanga. Kubera iyo mpamvu, igiciro cyibicuruzwa bivangwa na minisiteri yumye bikomeza kuba byinshi, kandi biragoye kumenyekanisha imyanda isanzwe ya minisiteri hamwe na pompe ya pompe ifite ubwinshi nubuso bwagutse. Ibicuruzwa byo mu rwego rwo hejuru bigenzurwa n’amasosiyete y’amahanga, abakora minisiteri yumye inyungu nkeya, igiciro gito; Ikoreshwa ryuruvange rurabura ubushakashatsi butunganijwe kandi bugamije, gukurikiza buhumyi ibyemezo byamahanga.

Igikoresho cyo gufata amazi nicyo kintu cyingenzi kivanga kugirango tunoze imikorere yamazi ya minisiteri ivanze yumye kandi nimwe mubintu byingenzi bivangwa kugirango hamenyekane ikiguzi cyibikoresho bya minisiteri yumye. Igikorwa nyamukuru cya selulose ether nukugumana amazi.

Uburyo bwibikorwa bya selile ether muri mortar nuburyo bukurikira:

(2)Cellulose etherigisubizo bitewe nuburyo bwimiterere ya molekuline yacyo, kugirango amazi yo muri minisiteri atoroshye gutakaza, kandi buhoro buhoro arekurwa mugihe kirekire, bigaha minisiteri amazi meza kandi ikora.
