Methyl selulose (MC) ikozwe mubicuruzwa bisanzwe

Methyl selulose (MC) ikomoka kuri selile, ni polymer karemano iboneka murukuta rw'utugingo ngengabuzima. Cellulose ni kimwe mu bintu byinshi byangiza umubiri ku isi, bikomoka cyane cyane ku biti by'ibiti na fibre. MC ikomatanyirizwa muri selile ikoresheje urukurikirane rw'imiti irimo gusimbuza amatsinda ya hydroxyl (-OH) muri molekile ya selile hamwe na methyl matsinda (-CH3).

Mugihe MC ubwayo ari imiti yahinduwe muburyo bwa chimique, ibikoresho byayo fatizo, selile, ikomoka kumasoko karemano. Cellulose irashobora gukurwa mubikoresho bitandukanye byibimera, birimo ibiti, ipamba, ikivuguto, nibindi bimera bya fibrous. Cellulose ikora gutunganya kugirango ikureho umwanda kandi ihindurwe muburyo bukoreshwa mugukora MC.

Iyo selile imaze kuboneka, ikora etherification kugirango yinjize amatsinda ya methyl kumugongo wa selile, bikavamo methyl selile. Iyi nzira ikubiyemo kuvura selile hamwe nuruvange rwa sodium hydroxide na methyl chloride mugihe cyagenwe.

Methyl selulose yavuyemo ni umweru kugeza kuri cyera, impumuro nziza, kandi idafite uburyohe butangirika mumazi akonje kandi bigatanga igisubizo kiboneye. Ikoreshwa cyane mu nganda zinyuranye, zirimo ibiryo, imiti, kwita ku muntu ku giti cye, no kubaka, kugira ngo ibyimbye, ituze, kandi ikora firime.

Mugihe MC ari imiti yahinduwe muburyo bwa chimique, ikomoka kuri selile karemano, bigatuma ibinyabuzima bishobora kwangirika kandi bitangiza ibidukikije kubikorwa byinshi.
