Carboxymethylcellulose (CMC), izwi kandi nka selulose gum, ni polymer itandukanye kandi ifite porogaramu zitandukanye mubikorwa bitandukanye.Uru ruganda, rukomoka kuri selile, rugaragaza imiterere yihariye ituma iba ingenzi mubice nkibiryo, imiti, imiti yo kwisiga, imyenda, nibindi byinshi.
Imiterere n'imiterere
Cellulose, polymer nyinshi cyane ku isi, ikora nkibice byibanze byubatswe murukuta rw'utugingo ngengabuzima.Numurongo wa polysaccharide ugizwe no gusubiramo ibice bya glucose bihujwe hamwe na β (1 → 4) glycosidic.Carboxymethylcellulose ni inkomoko ya selile yabonetse binyuze muburyo bwo guhindura imiti.
Ihinduka ryingenzi ririmo kwinjiza amatsinda ya carboxymethyl (-CH2-COOH) mumatsinda ya hydroxyl ya selile ya rugongo.Ubu buryo, busanzwe bukorwa binyuze muri etherification cyangwa esterification reaction, butanga amazi meza hamwe nibindi bintu byifuzwa kuri molekile ya selile.
Urwego rwo gusimbuza (DS) bivuga impuzandengo yimibare ya carboxymethyl yometse kuri buri gice cya anhydroglucose mumurongo wa selile.Ihindura cyane ibisubizo, ubwiza, nibindi biranga CMC.Indangagaciro za DS zo hejuru ziganisha ku gukemuka gukomeye hamwe nibisubizo binini.
Carboxymethylcellulose isanzwe iboneka mubyiciro bitandukanye, buri kimwe cyujuje ibisabwa byihariye.Aya manota aratandukanye mubipimo nka viscosity, urwego rwo gusimbuza, ingano yingingo, nubuziranenge.
Imwe mu miterere igaragara ya CMC nubushobozi bwayo bwo gukora ibisubizo biboneka mumazi.Ndetse no mubutumburuke buke, irashobora gutera ingaruka zibyibushye bitewe nurunigi rwa polymer hamwe no gukorana na molekile zamazi.Ibi bituma ikora neza cyane mubikorwa byinshi.
Byongeye kandi, carboxymethylcellulose yerekana ibintu byiza cyane byo gukora firime, bigatuma iba ingirakamaro mugukora ibifuniko na firime bifite impamyabumenyi zitandukanye kandi byoroshye.Izi firime zisanga porogaramu mubikorwa kuva mubipfunyika ibiryo kugeza kumiti.
Porogaramu
Ubwinshi bwa carboxymethylcellulose buturuka kumurongo wihariye wumutungo, bigatuma ubera muburyo butandukanye bwa porogaramu.Bimwe mubyingenzi bikoreshwa muri CMC harimo:
Inganda zikora ibiribwa: Mu nganda zibiribwa, carboxymethylcellulose ikora nka stabilisateur, ikabyimbye, na emulisiferi mu bicuruzwa byinshi.Bikunze gukoreshwa mubikomoka ku mata, isosi, imyambarire, ibicuruzwa bitetse, n'ibinyobwa kugirango bitezimbere ubwiza, umunwa, hamwe no gutekana neza.Byongeye kandi, CMC ikoreshwa muburyo butarimo gluten kugirango bigane imiterere ya gluten mubicuruzwa bitetse.
Imiti ya farumasi: CMC isanga ikoreshwa cyane muburyo bwa farumasi bitewe nubushobozi bwayo bwo kongera ububobere no guhagarikwa kwihagarikwa, emulisiyo, namavuta.Ikora nk'ibikoresho byo guhuza ibinini, guhindura ibishishwa mu mazi yo mu kanwa, hamwe na stabilisateur mu mavuta yo kwisiga hamwe n'amavuta yo kwisiga.Byongeye kandi, carboxymethylcellulose ikoreshwa nkigikoresho cyo gutwikira ibinini, bigafasha kurekura ibiyobyabwenge no kunoza kumira.
Amavuta yo kwisiga no kwita ku muntu ku giti cye: Mu kwisiga no kwita ku muntu ku giti cye, CMC ikora nk'ibyimbye, stabilisateur, hamwe n’ibikoresho bitanga amazi.Yinjijwe muburyo bwo kwisiga nka cream, amavuta yo kwisiga, shampo, hamwe nu menyo wamenyo kugirango yongere ubwiza, yongere ububobere, kandi itange uburyo bwiza, bumwe.
Imyenda: Mu nganda z’imyenda, carboxymethylcellulose ikoreshwa nkigikoresho kinini cyo kunoza uburyo bwo kuboha no guha gukomera imyenda.Irakoreshwa kandi nkibibyimbye mu icapiro ryimyenda kugirango harebwe uburinganire nuburemere bwibishushanyo mbonera.
Amavuta na gaze: CMC ikoreshwa mu nganda za peteroli na gaze nka viscosifier mu gucukura ibyondo.Ifasha kugenzura igihombo cyamazi, kunoza isuku, no gutobora imyobo mugihe cyo gucukura.Byongeye kandi, carboxymethylcellulose isanga ikoreshwa mumazi ya hydraulic yamenetse kugirango ahagarike ibimera no gutwara inyongeramusaruro.
Impapuro no gupakira: Mu nganda zimpapuro, CMC ikora nkumukozi wo gutwikira kugirango arusheho kunoza imiterere yimpapuro, kongera icapiro, no kongera ubukana bwamazi.Ikoreshwa kandi nkibikoresho bingana kunoza impapuro no kugabanya kwinjiza amazi.Byongeye kandi, carboxymethylcellulose ikoreshwa mubikoresho byo gupakira kugirango itange ubushuhe kandi inoze neza muri laminates.
Ubwubatsi: Carboxymethylcellulose ikoreshwa mubikoresho byubwubatsi nka minisiteri, grout, na plaster kugirango bitezimbere imikorere, gufatira hamwe no gufata amazi.Ikora nkibibyimbye na rheologiya ihindura, itanga uburyo bukwiye nibikorwa byibyo bikoresho.
Ibindi bisabwa: Kurenga inganda zavuzwe haruguru, CMC isanga ikoreshwa mubikorwa bitandukanye nk'imyenda yo kwisiga, ibifunga, ububumbyi, hamwe no gutunganya amazi.Guhinduranya kwayo no guhuza nibindi bintu bituma iba inyongera yingirakamaro muburyo butabarika.
Akamaro ninyungu
Ikoreshwa ryinshi rya carboxymethylcellulose rishobora guterwa ninyungu nyinshi ninyungu:
Guhinduranya: Ubushobozi bwa CMC bwo gukora imirimo myinshi, harimo kubyimba, gutuza, guhuza, no gukora firime, bituma ihinduka cyane mubikorwa bitandukanye.
Umutekano: Carboxymethylcellulose isanzwe izwi nkumutekano (GRAS) kugirango ikoreshwe ninzego zibishinzwe nk’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA).Itera ingaruka nke kubuzima bwabantu kandi ifite amateka maremare yo gukoresha neza ibiryo, imiti, nibicuruzwa byita kumuntu.
Ibidukikije-Byangiza ibidukikije: Nkibikomoka kuri selile, CMC ikomoka kumasoko y'ibimera ashobora kuvugururwa, bigatuma ibidukikije bibungabunga ibidukikije.Ntibishobora kwangirika kandi ntabwo bigira uruhare mu kwangiza ibidukikije.
Ikiguzi-Cyiza: Carboxymethylcellulose itanga igisubizo cyigiciro cyo kuzamura imitungo yibicuruzwa bitandukanye.Igiciro cyacyo gike ugereranije nibindi byongeweho bituma ihitamo kubakora inganda nyinshi.
Imikorere: Imiterere yihariye ya CMC, nkubushobozi bwayo bwo gukora ihagarikwa rihamye, geles zibyibushye, na firime zikomeye, bigira uruhare mukuzamura imikorere nubwiza bwibicuruzwa byanyuma.
Kubahiriza amabwiriza: Carboxymethylcellulose yubahiriza ibipimo ngenderwaho nibisabwa mu nganda zitandukanye, byemeza umutekano wibicuruzwa nubuziranenge.
carboxymethylcellulose (CMC) igira uruhare runini mu nganda nyinshi nka polymer itandukanye hamwe nibikorwa bitandukanye.Kuva mu biribwa no mu bya farumasi kugeza ku myenda n'ubwubatsi, CMC itanga imitungo idasanzwe izamura imikorere, ubwiza, n'imikorere y'ibicuruzwa byinshi n'ibicuruzwa.Umutekano wacyo, urambye, hamwe nigiciro-cyiza kurushaho bigira uruhare mubikorwa byacyo mubikorwa bigezweho.Mugihe ubushakashatsi nudushya bikomeje kwagura imyumvire ikomoka kuri selile, ikoreshwa nakamaro ka carboxymethylcellulose biteganijwe ko biziyongera cyane mumyaka iri imbere.
