Carboxymethylcellulose (CMC) na sitashi byombi ni polysaccharide, ariko bifite imiterere, imiterere n'imikorere bitandukanye.
Imiterere ya molekile:
1. Karuboksimetiliseli (CMC):
Carboxymethylcellulose ni ikintu gikomoka kuri cellulose, polymeri igizwe n'ibice bya glucose bihujwe n'imigozi ya β-1,4-glycosidic. Guhindura cellulose bikubiyemo kwinjiza amatsinda ya carboxymethyl binyuze mu gukwirakwiza ether, bigatuma carboxymethylcellulose ihinduka. Itsinda rya carboxymethyl rituma CMC ishonga mu mazi kandi igaha polymer imiterere yihariye.
2. Ifu y'ibinyampeke:
Ifuru ni karubohidrati igizwe n'ibice bya glucose bihujwe n'imigozi ya α-1,4-glycosidic. Ni polymer karemano iboneka mu bimera ikoreshwa nk'ikintu kibika ingufu. Molekile za carbohydrate muri rusange zigizwe n'ubwoko bubiri bwa polymer za glucose: amylose (imigozi igororotse) na amylopectin (imiterere y'imigozi ifite amashami).
Imiterere ifatika:
1. Karuboksimetiliseli (CMC):
Gushonga: CMC ishongera mu mazi bitewe n'uko hari amatsinda ya karuboksimetili.
Ubucucike: Igaragaza ubucucike bwinshi mu gikoresho, bigatuma igira akamaro mu bintu bitandukanye nko gutunganya ibiribwa no mu miti.
Umucyo: Ibisubizo bya CMC ubusanzwe biba bisobanutse neza.
2. Ifu y'ibinyampeke:
Gushonga: Ifu y'ibinyampeke idashobora gushonga mu mazi. Ikenera gushyushya mu mazi kugira ngo ishonge.
Ubushyuhe: Ifu y'ibinyampeke ifite ubushyuhe, ariko muri rusange iba iri hasi ugereranyije na CMC.
Umucyo: Ifu y'ibinyampeke ikunze kuba idasobanutse neza, kandi urwego rw'ubudasobanutse rushobora gutandukana bitewe n'ubwoko bw'ifu.
isoko:
1. Karuboksimetiliseli (CMC):
Ubusanzwe CMC ikorwa muri selulose ikomoka ku bimera nk'ibiti cyangwa ipamba.
2. Ifu y'ibinyampeke:
Ibimera nk'ibigori, ingano, ibirayi n'umuceri bikungahaye kuri sitati. Ni ikintu cy'ingenzi mu biribwa byinshi by'ibanze.
Uburyo bwo gukora:
1. Karuboksimetiliseli (CMC):
Ikorwa rya CMC rikubiyemo uburyo cellulose ikora etherification hamwe na aside chloroacetic mu buryo bwa alkaline. Iyi reaction ituma amatsinda ya hydroxyl muri cellulose asimburwa n'amatsinda ya carboxymethyl.
2. Ifu y'ibinyampeke:
Gukuramo ifumbire bisaba gusenya uturemangingo tw’ibimera no gutandukanya utunyangingo tw’ifumbire. Ifumbire ikurwamo ishobora kunyura mu nzira zitandukanye, harimo no guhindura no gushyiramo gelatin, kugira ngo ibone imiterere ikenewe.
Intego n'ishyirwa mu bikorwa:
1. Karuboksimetiliseli (CMC):
Inganda z'ibiribwa: CMC ikoreshwa nk'ikintu gikomeza ubushyuhe, gitera imbaraga kandi gitera imbaraga mu biribwa bitandukanye.
Imiti: Bitewe n'ubushobozi bwayo bwo gufatana no gusenyuka, ikoreshwa mu miterere y'imiti.
Gucukura amavuta: CMC ikoreshwa mu mazi acukura amavuta kugira ngo igenzure rheology.
2. Ifu y'ibinyampeke:
Inganda z'ibiribwa: Ifu y'ibinyampeke ni yo igize ibiryo byinshi kandi ikoreshwa nk'ikintu gikomeza ubushyuhe, ikintu gitera ubwinshi bw'ibiryo n'ikintu gitera imbaraga.
Inganda z'imyenda: Ifu ikoreshwa mu gupima imyenda kugira ngo ikomeze gukomera kw'imyenda.
Inganda z'impapuro: Ifumbire ikoreshwa mu gukora impapuro kugira ngo yongere imbaraga z'impapuro kandi inoze imiterere y'ubuso.
Nubwo CMC na sitachi byombi ari polysaccharide, bifite itandukaniro mu miterere ya molekile, imiterere y’umubiri, amasoko, inzira z’umusaruro n’ikoreshwa ryabyo. CMC ishongera mu mazi kandi ifite ubukana bwinshi kandi ikunze gukundwa mu ikoreshwa risaba iyo miterere, mu gihe sitachi ari polysaccharide ikoreshwa cyane mu nganda z’ibiribwa, imyenda n’impapuro. Gusobanukirwa iri tandukaniro ni ingenzi mu guhitamo polymer ikwiye gukoreshwa mu nganda n’ubucuruzi bwihariye.
