Methyl cellulose (MC) yopangidwa ndi chilengedwe

Methyl cellulose (MC) ndi yochokera kwa cellulose, yomwe ndi polymer yachilengedwe yomwe ili m'makoma a cell a mbewu. Cellulose ndi imodzi mwazinthu zochulukirapo kwambiri padziko lapansi, makamaka zimapota kuchokera ku prglyp ndi ulusi wa thonje. MC imapangidwa chifukwa cha cellulose kudzera mwa mitundu ingapo yamankhwala yomwe imakhudzana ndi magulu a hydroxyl (-Oh) mu ma celluluse molekyu ndi magulu a methyl (-ch3).

Pomwe McYokha ndiwosintha mwadzidzidzi, zopangira, cellulose, zimachokera ku zinthu zachilengedwe. Ma cellulose amatha kuchotsedwa pazomera zosiyanasiyana zomera, kuphatikiza nkhuni, thonje, hemp, ndi mbewu zina zamiyala. Cellulose yomwe imapezeka ndikuchotsa zodetsa ndikusintha kukhala mawonekedwe othandiza pakupanga MC.

Cellulose ikapezeka, imapezeka kumangiriza kufalitsa mabungwe am'mimba a celyulose, chifukwa cha mapangidwe a methyl cellulose. Izi zimaphatikizapo kuchitira cellulose ndi sodium hydroxide ndi methyl chloride pansi pamikhalidwe yolamulidwa.

Kuchokera ku methyl cellose ndi yoyera-yoyera, yopanda fungo, komanso yopanda tanthauzo yomwe imasungunuka m'madzi ozizira ndikupanga njira yothetsera ma viscous. Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo chakudya, mankhwala opangira mankhwala, chisamaliro chawo komanso zomanga, chifukwa cha kukula kwake, ndikukhazikika, komanso kukhazikika kwa makanema.

Ngakhale MC ndi mphukira yosinthidwa mwanjira yosinthidwa, imachokera ku cellulose yachilengedwe, ndikupangitsa kuti ikhale yosavuta komanso yopatsa chidwi pazogwiritsa ntchito zambiri.
