I-Methyl cellulose (MC) eyenziwe ngemveliso yendalo

I-Methyl cellulose (MC) yi-derivative ye-cellulose, eyi-polymer yendalo efumaneka kwiindonga zeeseli zezityalo. I-Cellulose yenye yezona zinto zininzi eziphilayo emhlabeni, ezifumaneka kakhulu kwi-pulp yomthi kunye neefayibha zekotoni. I-MC yenziwe nge-cellulose ngothotho lweempendulo zeekhemikhali ezibandakanya ukutshintshwa kwamaqela e-hydroxyl (-OH) kwi-molecule ye-cellulose ngamaqela e-methyl (-CH3).

Nangona i-MC ngokwayo iyikhompawundi eguqulwe ngokweekhemikhali, izinto zayo ezikrwada, i-cellulose, zivela kwimithombo yendalo. I-Cellulose ingakhutshwa kwizinto ezahlukeneyo zezityalo, kuquka umthi, umqhaphu, i-hemp, kunye nezinye izityalo ezine-fibrous. I-cellulose iyacutshungulwa ukuze isuse ukungcola kwaye iguqulwe ibe yindlela enokusetyenziselwa ukuvelisa i-MC.

Xa sele ifunyenwe i-cellulose, ifakwa kwi-etherification ukuze ingenise amaqela e-methyl kwi-cellulose backbone, nto leyo ebangela ukwakheka kwe-methyl cellulose. Le nkqubo ibandakanya ukunyanga i-cellulose ngomxube we-sodium hydroxide kunye ne-methyl chloride phantsi kweemeko ezilawulwayo.

I-methyl cellulose ephumayo yipowder emhlophe ukuya kwemhlophe, engenavumba, kwaye engenancasa enyibilikayo emanzini abandayo kwaye yenza isisombululo esiqinileyo. Isetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanya ukutya, amayeza, ukunakekelwa komntu, kunye nokwakha, ngenxa yeempawu zayo zokutyeba, ukuzinza, kunye nokwenza ifilimu.

Nangona i-MC iyikhompawundi eguqulwe ngokweekhemikhali, isuka kwi-cellulose yendalo, nto leyo eyenza ukuba ibe lukhetho olubolayo nolunobuhlobo nokusingqongileyo kwiindlela ezininzi zokusetyenziswa.
