Methylcellulose

Methyl selulose, mu magambo ahinnye yitwa MC, izwi kandi nka selile methyl ether, ni ether ya selile idasanzwe. Ifite isura yera, yumuhondo yijimye cyangwa yijimye yijimye yijimye, granular cyangwa fibrous, impumuro nziza, uburyohe, idafite uburozi kandi butarakara, hygroscopique.

Methylcellulose irashobora gushonga muri acide glacial acetique, ariko ntigishobora gushonga mumashanyarazi nka Ethanol, ether, acetone, na chloroform. Methylcellulose ifite imiterere yihariye ya gel. Iyo ushongeshejwe mumazi ashyushye hejuru ya 50 ° C, irashobora gukwirakwira vuba ikabyimba gukora gel. Iyo ubushyuhe bwamazi bugabanutse munsi ya 50 ° C, bizashonga mumazi kugirango bibe igisubizo cyamazi. Ibisubizo byamazi nuburyo bwa gel birashobora gukorana.

Gutegura methyl selulose ikoresha selile isanzwe nka pamba ya pamba nigiti cyibiti nkibikoresho fatizo, kandi ikavurwa na alkali (nka sodium hydroxide, nibindi) kugirango ibone selile ya alkali, hanyuma igashyirwa muri ether yongeramo methyl chloride. Imyitwarire ku bushyuhe runaka, nyuma yo gukaraba, kutabogama, kubura umwuma, gukama nibindi bikorwa, ukurikije ubuziranenge bwibicuruzwa nibirimo tekinike, methyl selulose irashobora kugabanywa murwego rwa farumasi methyl selulose, urwego rwibiryo methyl selulose, intego rusange ya methyl selulose nibindi bicuruzwa .

Methylcellulose irwanya aside na alkalis, amavuta, ubushyuhe, mikorobe n'umucyo. Ifite umubyimba mwiza, gukora firime, kugumana amazi, kwigana, gutose, gutatanya, hamwe nibintu bifatika.

Methylcellulose ifite uburyo butandukanye bwo kumanura ibintu, uhereye ku mwenda, wino, ibifata kugeza imyenda, gucapa no gusiga irangi kugeza imiti no gutunganya ibiryo. Inganda nyinshi zifite ibisabwa kubicuruzwa kandi bifite umwanya mugari witerambere. Nyuma yiterambere rirambye ryigihe kirekire, inganda zigihugu cya methyl selulose zagize igipimo runaka, kandi ibicuruzwa bigenda birushaho kuba byiza, ariko bigomba kuba byiza cyane mubijyanye niterambere ryuzuye!
