Methyl cellulose (MC) ikozwe mu bicuruzwa karemano

Methyl cellulose (MC) ni ikintu gikomoka kuri cellulose, ikaba ari polymer karemano iboneka mu rukuta rw'uturemangingo tw'ibimera. Cellulose ni imwe mu myunyungugu iboneka cyane ku Isi, ikomoka cyane cyane mu bimera bito n'ipamba. MC ikorwa muri cellulose binyuze mu buryo butandukanye bw'ibinyabutabire busaba gusimbuza amatsinda ya hydroxyl (-OH) muri molekyuli ya cellulose n'amatsinda ya methyl (-CH3).

Nubwo MC ubwayo ari ikintu cyahinduwe mu buryo bw'imiti, ibikoresho byayo by'ibanze, cellulose, bikomoka ku bintu karemano. Cellulose ishobora gukurwa mu bikoresho bitandukanye by'ibimera, birimo imbaho, ipamba, hemp, n'ibindi bimera bifite fibre. Cellulose iratunganywa kugira ngo ikureho imyanda maze ihindurwemo uburyo bwo gukoreshwa mu gukora MC.

Iyo cellulose imaze kuboneka, irahinduka etherification kugira ngo ishyire amatsinda ya methyl ku mugongo wa cellulose, bigatuma habaho methyl cellulose. Iyi nzira ikubiyemo kuvura cellulose uvanze na sodium hydroxide na methyl chloride mu gihe hagenzuwe.

Selulosi ya methyl ivamo ni ifu y'umweru kuva ku ibara ry'umweru, idafite impumuro, kandi idafite uburyohe, ishongeshwa mu mazi akonje kandi igakora umuti utose. Ikoreshwa cyane mu nganda zitandukanye, harimo ibiribwa, imiti, kwita ku buzima bwite, n'ubwubatsi, kubera ubushobozi bwayo bwo gukurura, gutuza no gukora filime.

Nubwo MC ari ikintu cyahinduwe hakoreshejwe imiti, ikomoka kuri cellulose karemano, bigatuma iba amahitamo yo kubora no kurengera ibidukikije ku bikorwa byinshi.
