I-methyl cellulose (MC) eyenziwe ngomkhiqizo wemvelo

I-Methyl Cellulose (MC) iyisisulu se-cellulose, okuyi-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. I-cellulose ingenye yezindlela eziningi ze-organic emhlabeni, zitholwe ngokuyinhloko kusuka ku-soli pulp kanye ne-cotton fibers. I-MC ihlelwe kusuka ku-cellulose ngokusebenzisa uchungechunge lokuphendula kwamakhemikhali okubandakanya ukufakwa esikhundleni samaqembu we-hydroxyl (-OH) kwi-cellulose molecule ngamaqembu we-cellulose (-CH3).

Ngenkathi i-MC ngokwayo iyindawo eguqulwe ngamakhemikhali, impahla yayo eluhlaza, iselula, isuselwa emithonjeni yemvelo. I-cellulose ingakhishwa kusuka ezintweni ezihlukene zezitshalo, kufaka phakathi izinkuni, ukotini, i-hemp, nezinye izitshalo ze-fibrous. I-cellulose ithola ukucubungula ukususa ukungcola bese ikuguqula ibe yifomu elisebenzisekayo ekhiqizweni le-MC.

Lapho iselula selitholakele, lithola ukusheshisa ukwethula amaqembu we-methyl ku-cellulose backbone, okuholela ekwakhekeni kwe-methyl cellulose. Le nqubo ifaka ukwelapha iselula ngenhlanganisela ye-sodium hydroxide ne-methyl chloride ngaphansi kwezimo ezilawulwayo.

I-methyl cellulose ephumayo iyimpuphu emhlophe emhlophe-emhlophe, engenamphundla, futhi engenamsoco okuncibilikayo emanzini abandayo futhi yakha isixazululo se-viscous. Kusetshenziswa kabanzi kwizimboni ezahlukahlukene, kubandakanya nokudla, amakhamithi, ukunakekelwa komuntu siqu, nokwakha, ngokuqina, nokuzinza, kanye nezakhiwo ezenziwe ngefilimu.

Ngenkathi i-MC iyindawo elungisiwe yamakhemikhali, itholakala kwi-cellulose yemvelo, iyenze ibe inketho ye-biodegradable nemvelo yezicelo eziningi.
