Iyini inqubo yokukhiqiza i-methylcellulose?

I-Methylcellulose iwuhlobo lwe-polymer esekwe ku-cellulose esetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi ukudla, imithi, kanye nezimonyo. Kuyimpushana emhlophe, engenaphunga, enganambitheki encibilika emanzini abandayo futhi yakha ijeli lapho ishiswa. Ikhiqizwa ngokwelapha i-cellulose nge-methyl chloride ne-sodium hydroxide.

Inqubo yokukhiqiza i-methylcellulose ihilela izinyathelo ezimbalwa. Isinyathelo sokuqala ukuthola impahla eluhlaza, ngokuvamile i-cellulose. I-cellulose ingatholakala emithonjeni ehlukahlukene, njenge-pulp yokhuni, ukotini, neminye imicu yezitshalo. I-cellulose ibe isiphathwa nge-methyl chloride ne-sodium hydroxide ukuze kwakhiwe i-methylcellulose polymer.

Isinyathelo esilandelayo ukuhlanza i-methylcellulose. Lokhu kwenziwa ngokukhipha ukungcola okufana ne-lignin, i-hemicellulose, nezinye izinto ezingase ziphazamise izici ezifunwayo ze-methylcellulose. Lokhu ngokuvamile kwenziwa ngokwelapha i-methylcellulose nge-asidi noma i-alkali, noma ngokusebenzisa inqubo ebizwa ngokuthi i-fractionation.

Uma i-methylcellulose isihlanziwe, bese yomiswa futhi igaywe ibe yimpushana. Le mpushana isuke isilungele ukusetshenziswa ezinhlobonhlobo zezicelo.

I-Methylcellulose ingasetshenziswa njenge-ejenti yokuqina, i-emulsifier, i-stabilizer, noma i-ejenti ye-gelling. Ibuye isetshenziswe emikhiqizweni yokudla efana no-ayisikhilimu, amasaladi okugqoka, namasoso. Kwemithi, isetshenziswa njenge-binder, i-ejenti yokumisa, kanye ne-tablet coating. Kwezimonyo, isetshenziswa njenge-thickener, emulsifier, kanye ne-stabilizer.

Inqubo yokukhiqiza i-methylcellulose ilula futhi iyasebenza. Kuyindlela engabizi kakhulu yokukhiqiza imikhiqizo enhlobonhlobo enezinhlobonhlobo zokusetshenziswa. Kuphinde kube yinto ephephile nengenabo ubuthi engasetshenziswa ezinhlelweni ezahlukene.
