Yintoni inkqubo yokwenziwa kwe-methylcellulose?

I-Methylcellulose luhlobo lwepolymer esekwe kwi-cellulose esetyenziswa kwizicelo ezahlukeneyo, kubandakanya ukutya, amayeza, kunye nezithambiso. Ngumgubo omhlophe, ongenavumba, ongenancasa onyibilika emanzini abandayo kwaye wenze ijeli xa ushushu. Iveliswa ngokuphatha i-cellulose nge-methyl chloride kunye ne-sodium hydroxide.

Inkqubo yokwenziwa kwe-methylcellulose ibandakanya amanyathelo amaninzi. Inyathelo lokuqala kukufumana imathiriyeli ekrwada, edla ngokuba yi-cellulose. I-cellulose inokufumaneka kwimithombo eyahlukeneyo, efana ne-pulp yamaplanga, umqhaphu, kunye neminye imicu yezityalo. Emva koko i-cellulose iphathwa nge-methyl chloride kunye ne-sodium hydroxide ukwenza i-methylcellulose polymer.

Inyathelo elilandelayo kukucoca i-methylcellulose. Oku kwenziwa ngokususa ukungcola okufana ne-lignin, i-hemicellulose, kunye nezinye izinto ezinokuphazamisa izinto ezifunwayo ze-methylcellulose. Oku ngokuqhelekileyo kwenziwa ngokuphatha i-methylcellulose nge-asidi okanye i-alkali, okanye ngokusebenzisa inkqubo ebizwa ngokuba yi-fractionation.

Emva kokuba i-methylcellulose ihlanjululwe, yomiswa kwaye igutywe ibe ngumgubo. Lo mgubo ulungele ukusetyenziswa kwizicelo ezahlukeneyo.

I-Methylcellulose inokusetyenziswa njenge-ejenti yokuqina, i-emulsifier, i-stabilizer, okanye i-gelling agent. Iyasetyenziswa nakwiimveliso zokutya ezifana ne-ayisikrimu, izinxibo zesaladi, kunye neesosi. Kumayeza, isetyenziswa njenge-binder, i-agent exhomayo, kunye ne-tablet coating. Kwizinto zokuthambisa, isetyenziswa njenge-thickener, emulsifier, kunye ne-stabilizer.

Inkqubo yokwenziwa kwe-methylcellulose ilula kwaye iyasebenza. Yindlela engabizi kakhulu yokuvelisa iintlobo ezininzi zeemveliso kunye nosetyenziso oluhlukeneyo. Ikwayinto ekhuselekileyo neyiyo engeyotyhefu enokusetyenziswa kwiintlobo ngeentlobo zezicelo.
