Carboxymethyl selulose selelose ether?

Intangiriro kuri Carboxymethyl Cellulose (CMC)

Carboxymethyl selulose, ikunze kwitwa CMC, ni inkomoko itandukanye ya selile, polimeri isanzwe ibaho iboneka murukuta rw'utugingo ngengabuzima. Iraboneka hifashishijwe imiti ihindura selile, cyane cyane mugutangiza amatsinda ya carboxymethyl (-CH2-COOH) kumugongo wa selile.

Imiterere n'imiterere

CMC igumana imiterere shingiro ya selile, ikaba ari umurongo ugizwe na molekile ya glucose ihujwe na β (1 → 4) glycosidic. Ariko, kumenyekanisha amatsinda ya carboxymethyl atanga ibintu byinshi byingenzi muri CMC:

Amazi meza: Bitandukanye na selile kavukire, idashobora gushonga mumazi, CMC irashonga cyane mumazi ashyushye nubukonje bitewe na hydrophilique ya groupe ya carboxymethyl.

Umubyimba: CMC nigikorwa cyiza cyo kubyimba, kigakora ibisubizo byijimye kumitekerereze mike. Uyu mutungo uhesha agaciro muburyo butandukanye bwo gusaba, harimo ibiryo, imiti, nibicuruzwa byawe bwite.

Ubushobozi bwo Gukora Filime: CMC irashobora gukora firime mugihe yashyizwe mubisubizo, ikagira akamaro mubisabwa aho bisabwa firime yoroheje, yoroheje, nko mubitambaro no kubifata.

Guhuzagurika no guhuza: CMC ihagaze neza muburyo butandukanye bwa pH nubushyuhe bwubushyuhe, bigatuma ihuza nibindi bikoresho bitandukanye kandi bikwiranye nibikorwa bitandukanye.

Porogaramu

Imiterere itandukanye ya CMC isanga ikoreshwa mubikorwa byinshi:

Inganda zikora ibiribwa: CMC ikoreshwa cyane nkibyimbye, stabilisateur, na emulifisiyeri mubicuruzwa byibiribwa nka sosi, imyambarire, ice cream, nibikoni. Itezimbere ubwiza, umunwa, hamwe na tekinike ihamye.

Imiti ya farumasi: Mubikorwa bya farumasi, CMC ikora nka binder, idasenyuka, kandi igenzurwa-kurekura ibinini na capsules. Ubushobozi bwayo bwo gukora geles ihamye nayo ituma igira akamaro muburyo bwo kwisiga nka cream na lisansi.

Ibicuruzwa byita ku muntu ku giti cye: CMC ni ikintu gikunze kugaragara mu bicuruzwa byita ku muntu nka menyo y’amenyo, shampo, na cream, aho ikora nk'ibyimbye, stabilisateur, hamwe nububiko.

Inganda zimpapuro: Mu gukora impapuro, CMC ikoreshwa nkibikoresho bingana kugirango igabanye imbaraga zimpapuro, ubworoherane, hamwe no kwakira wino. Irakora kandi nk'imfashanyo yo kugumana, ifasha guhuza uduce duto twuzuza impapuro.

Imyenda: CMC ikoreshwa mugucapura imyenda no gusiga amarangi nkumuhinduzi mwinshi hamwe na rheologiya yo gucapa paste no koga.

Gucukura Amavuta: Mu nganda zicukura peteroli, CMC yongewe kumazi yo gucukura kugirango igabanye ubukonje, kugabanya igihombo cyamazi, no gusiga amavuta.

Ikoreshwa ryinshi rya carboxymethyl selulose ryitirirwa uburyo bwihariye bwo guhuza imitungo, ituma ikoreshwa mubikorwa bitandukanye. Ibinyabuzima byangiza kandi bidafite ubumara bikomeza kugira uruhare mu kwiyegereza kwayo nkibidukikije birambye kandi bitangiza ibidukikije ubundi buryo bwa polymrike ya syntetique mubikorwa byinshi.

Carboxymethyl selulose mubyukuri ni selile ya ether hamwe nibintu byinshi byifashishwa bitewe nubushake bwamazi, imiterere yibyibushye, ituze, hamwe no guhuza nibindi bintu. Akamaro kayo kanyuze mu nganda, kukigira ikintu cyiza mubicuruzwa byinshi.
