Ibisobanuro ku bicuruzwa
Carboxymethyl Cellulose (CMC) niyongera ibiryo bisanzwe, kandi umunyu wa sodium (sodium carboxymethyl selulose) ukoreshwa nkimbunda na paste.Sodium carboxymethyl selulose yumuti: amazi abira ariko umubare ntushobora kurenga 0.5% - 0.7% sodium carboxymethyl selulose umuti ufata sodium carboxymethyl selulose 0.5g, ongeramo amazi 100ml, gushyushya no guteka, kugeza bishonge burundu.Ongeramo amazi make kugirango wishyure umwuka mbere yo guteka..Ku nshuro yambere, 1.85g silika gel na 5ml sodium carboxymethyl selulose yumuti wamazi byafashwe bishyirwa mubikombe byamata.Ahasigaye, 1.11g silika gel na 3ml sodium carboxymethyl selulose yumuti wamazi byafashwe buri gihe.Gusya mu cyerekezo kimwe kugeza igihe nta bubyimba, ururenda rushobora kuba umurongo.Cellulose naturel niyo ikwirakwizwa cyane kandi polysaccharide nyinshi muri kamere.Ubu buryo bwo guhindura tekinike ya selile yibanda cyane kuri etherification na esterification.Carboxymethylation ni bumwe mu buhanga bwa etherification.Cellulose nyuma ya carboxymethylation carboxymethyl selulose (CMC), igisubizo cyayo cyamazi gifite umubyimba, gukora firime, guhuza, gufata amazi, kurinda colloidal, emulisation no guhagarikwa, bikoreshwa cyane muri peteroli, ibiryo, ubuvuzi, imyenda nimpapuro, nimwe mubyingenzi. selile ether
Imiterere yumubiri
Sodium carboxymethyl selulose (CMC) ni anionic selulose ether, isura yifu ya fibre yera cyangwa yumuhondo nkeya cyangwa ifu yera, nta mpumuro, uburyohe, idafite uburozi;Gukemura mumazi akonje cyangwa ashyushye, ugakora igisubizo kiboneye hamwe nubwiza runaka.Igisubizo ntaho kibogamiye cyangwa alkaline nkeya, ntigishobora gushonga muri Ethanol, ether, inzoga ya isopropyl, acetone nindi miti ikomoka ku buhinzi, ariko igashonga muri Ethanol cyangwa acetone irimo amazi 60%.Ni hygroscopique na Photothermal stabilite, kandi ubukonje buragabanuka hamwe no kwiyongera kwubushyuhe.Igisubizo gihamye kuri PH 2 ~ 10, na PH iri munsi ya 2. Hariho imvura igwa, kandi ubukonje buragabanuka mugihe agaciro ka PH kari hejuru ya 10. Ubushyuhe bwamabara bwari 227 ℃, ubushyuhe bwa karubone bwari 252 ℃, n'ubuso bwubuso bwa 2% igisubizo cyamazi cyari 71mn / n.
