Methyl cellulose (MC) yakagadzirwa nechigadzirwa chechisikigo

Methyl cellulose (MC) inotorwa kubva kune cellulose, inova yakasikwa polymer inowanikwa musero madziro ezvirimwa. Cellulose ndeimwe yeakawanda kwazvo organic komisheni paPasi, inonyanya kucheneswa kubva muhuni pulp uye machira ekotoni. MC inogadzirwa kubva ku cellulose kuburikidza nekutevedzana kwemakemikari maitiro anosanganisira kutsiva hydroxyl mapoka (-OH) mu cellulose molecule ine methyl mapoka (-CH3).

Nepo MC pachayo iri kemikari yakagadziridzwa musanganiswa, iyo mbishi, cellulose, inotorwa kubva kune zvakasikwa masosi. Cellulose inogona kutorwa kubva kune dzakasiyana siyana zvirimwa, zvinosanganisira huni, donje, hemp, uye zvimwe fibrous zvirimwa. Iyo cellulose inogadziriswa kubvisa tsvina uye kuishandura kuita fomu inoshandisika yekugadzira MC.

Kana iyo cellulose yawanikwa, inopinda etherification yekuunza methyl mapoka pane cellulose musana, zvichikonzera kuumbwa kwemethyl cellulose. Iyi nzira inosanganisira kurapa cellulose nemusanganiswa we sodium hydroxide uye methyl chloride pasi pemamiriro ekudzora.

Iyo inozobuda methyl cellulose ichena kune-chena, isina kunhuhwirira, uye isinganakidze hupfu inonyungudika mumvura inotonhora uye inoita viscous solution. Inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, anosanganisira chikafu, mishonga, kutarisirwa kwevanhu, uye kuvaka, nekuda kwekukora, kudzikamisa, uye kugadzira firimu.

Nepo MC iri musanganiswa wemakemikari, inotorwa kubva kune yakasikwa cellulose, ichiita kuti ive biodegradable uye ine hushamwari sarudzo kune akawanda maapplication.
