I-Methyl cellulose (MC) eyenziwe ngomkhiqizo wemvelo

I-Methyl cellulose (MC) iyi-derivative ye-cellulose, okuyi-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. I-Cellulose ingenye yamakhemikhali e-organic amaningi kakhulu eMhlabeni, atholakala kakhulu ku-pulp yokhuni kanye ne-cotton fibers. I-MC yenziwa kusuka ku-cellulose ngochungechunge lwezimpikiswano zamakhemikhali ezihilela ukufakwa esikhundleni kwamaqembu e-hydroxyl (-OH) ku-molecule ye-cellulose namaqembu e-methyl (-CH3).

Nakuba i-MC ngokwayo iyinhlanganisela eguqulwe ngamakhemikhali, izinto zayo zokusetshenziswa, i-cellulose, itholakala emithonjeni yemvelo. I-cellulose ingakhishwa ezintweni zezitshalo ezahlukahlukene, okuhlanganisa ukhuni, ukotini, i-hemp, nezinye izitshalo ezinemicu. I-cellulose iyacutshungulwa ukuze kususwe ukungcola futhi kuyiguqule ibe yindlela engasetshenziswa ekukhiqizeni i-MC.

Uma i-cellulose isitholakele, ifakwa i-etherification ukuze ifake amaqembu e-methyl kumgogodla we-cellulose, okuholela ekwakhekeni kwe-methyl cellulose. Le nqubo ihilela ukwelapha i-cellulose ngengxube ye-sodium hydroxide kanye ne-methyl chloride ngaphansi kwezimo ezilawulwayo.

I-methyl cellulose ephumayo iyimpuphu emhlophe kuya kwemhlophe, engenaphunga, futhi engenambitheki encibilikayo emanzini abandayo futhi yakha isixazululo esiqinile. Isetshenziswa kabanzi ezimbonini ezahlukahlukene, okuhlanganisa ukudla, imithi, ukunakekelwa komuntu siqu, kanye nokwakhiwa, ngenxa yezakhiwo zayo eziqinile, ezizinzisayo, kanye nezakha ifilimu.

Nakuba i-MC iyinhlanganisela eguqulwe ngamakhemikhali, itholakala ku-cellulose yemvelo, okwenza kube inketho ebolayo futhi enobungani nemvelo yezinhlelo zokusebenza eziningi.
