Carboxymethylcellulose (CMC) ni inyongeramusaruro ikora cyane mu nganda zitandukanye nk'ibiribwa, imiti, gukora impapuro, imyenda, n'ubucukuzi. Bikomoka kuri selile karemano, ikungahaye cyane ku bimera n'ibindi binyabuzima. CMC ni polymer-amazi-eruber polymer ifite ibintu byihariye birimo viscosity, hydration, adhesion and adhesion.
Ibiranga CMC
CMC ni inkomoko ya selile ihindurwa muburyo bwo kwinjiza amatsinda ya carboxymethyl mumiterere yayo. Ihinduka ryongera imbaraga za hydrophilicity ya selile, bityo bikanoza imikorere. Imiterere ya CMC biterwa nurwego rwayo rwo gusimbuza (DS) nuburemere bwa molekile (MW). DS isobanurwa nkimpuzandengo yimibare ya carboxymethyl kumurwi wa glucose murwego rwumugongo wa selile, mugihe MW yerekana ingano nogukwirakwiza iminyururu ya polymer.
Imwe mu miterere yingenzi ya CMC nubushobozi bwayo bwamazi. CMC irashobora gushonga byoroshye mumazi, ikora igisubizo kibonerana gifite pseudoplastique. Iyi myitwarire ya rheologiya ituruka ku mikoranire hagati ya molekile ya CMC, bigatuma igabanuka ryijimye ryatewe no guhangayika. Imiterere ya pseudoplastique yibisubizo bya CMC ituma bikwiranye na progaramu zitandukanye nka thickeners, stabilisateur, hamwe no guhagarika abakozi.
Ikindi kintu cyingenzi kiranga CMC nubushobozi bwayo bwo gukora film. Ibisubizo bya CMC birashobora gutabwa muri firime zifite imiterere yubukorikori nziza, gukorera mu mucyo, no guhinduka. Izi firime zirashobora gukoreshwa nka coatings, laminates nibikoresho byo gupakira.
Mubyongeyeho, CMC ifite uburyo bwiza bwo guhuza no guhuza. Ikora umurunga ukomeye hamwe nubuso butandukanye, harimo ibiti, ibyuma, plastike nigitambara. Uyu mutungo watumye hakoreshwa CMC mugukora ibicuruzwa, ibifata hamwe na wino.
Ubukonje bwa CMC
Ubwiza bwibisubizo bya CMC biterwa nibintu byinshi nko kwibanda, DS, MW, ubushyuhe, na pH. Muri rusange, ibisubizo bya CMC byerekana ububobere buke cyane, DS, na MW. Viscosity nayo yiyongera hamwe no kugabanuka kwubushyuhe na pH.
Ubwiza bwibisubizo bya CMC bugenzurwa nubusabane hagati yiminyururu ya polymer na molekile ya solvent mugisubizo. Molekile ya CMC ikorana na molekile zamazi binyuze mumigozi ya hydrogène, ikora igishishwa cyamazi gikikije iminyururu ya polymer. Igishishwa cya hydration igabanya umuvuduko wiminyururu ya polymer, bityo bikongerera ubwiza bwumuti.
Imyitwarire ya rheologiya yibisubizo bya CMC irangwa no gutembera gutemba, bisobanura isano iri hagati yimyitwarire yimisatsi nigipimo cyogukemura. Ibisubizo bya CMC byerekana imyitwarire idahwitse ya Newtonian, bivuze ko ububobere bwabo buhinduka nigipimo cyogosha. Ku gipimo gito cyogosha, ubwiza bwibisubizo bya CMC buri hejuru, mugihe kurwego rwo hejuru rwogosha, ubwiza buragabanuka. Iyi myitwarire yo kunanura imisatsi iterwa numurongo wa polymer uhuza kandi urambuye munsi yimyitozo ngororamubiri, bigatuma imbaraga za intermolecular hagati yiminyururu no kugabanuka kwijimye.
Ikoreshwa rya CMC
CMC ikoreshwa cyane mubice bitandukanye kubera imiterere yihariye nimyitwarire ya rheologiya. Mu nganda zibiribwa, CMC ikoreshwa nkibyimbye, stabilisateur, emulifier hamwe nuburyo bwiza. Yongewe kubiribwa nka ice cream, ibinyobwa, isosi nibicuruzwa bitetse kugirango bitezimbere imiterere, bihoraho hamwe nubuzima bwiza. CMC irinda kandi gushiraho kristu ya ice mu biribwa bikonje, bikavamo ibicuruzwa byoroshye, birimo amavuta.
Mu nganda zimiti, CMC ikoreshwa nkibikoresho bihuza, bidahwitse kandi bigenzurwa mugusohora ibinini. Kunoza ubworoherane nubworoherane bwifu kandi urebe neza uburinganire nuburinganire bwibinini. Bitewe n'imiterere ya mucoadhesive na bioadhesive, CMC nayo ikoreshwa nkibintu byoroshye mu kuvura amaso, izuru, no mu kanwa.
Mu nganda zimpapuro, CMC ikoreshwa nkinyongeramusaruro itose, igipfundikizo hamwe nubunini bwikinyamakuru. Itezimbere kugumya no gutemba, byongera imbaraga zimpapuro nubucucike, kandi bitanga ubuso bworoshye kandi bubengerana. CMC ikora kandi nk'inzitizi y'amazi n'amavuta, ikabuza wino cyangwa andi mazi kwinjira mu mpapuro.
Mu nganda z’imyenda, CMC ikoreshwa nkibikoresho bingana, icapura umubyimba, hamwe nugufasha irangi. Itezimbere fibre, yongerera amabara kwinjira no gukosorwa, kandi igabanya ubushyamirane n'iminkanyari. CMC itanga kandi ubwitonzi no gukomera kumyenda, bitewe na DS na MW ya polymer.
Mu bucukuzi bw'amabuye y'agaciro, CMC ikoreshwa nka flocculant, inhibitor na rheologiya ihindura amabuye y'agaciro. Itezimbere gutuza no kuyungurura ibinini, bigabanya gutandukana nitsinda ryamakara, kandi igenzura ubwiza bwihagarikwa no guhagarara. CMC igabanya kandi ingaruka z’ibidukikije mu bucukuzi bw’amabuye y'agaciro hagabanywa ikoreshwa ry’imiti y’ubumara n’amazi.
mu gusoza
CMC ninyongeramusaruro zinyuranye kandi zifite agaciro zigaragaza imiterere yihariye nubukonje bitewe nimiterere yimiti no gukorana namazi. Ubushobozi bwayo, ubushobozi bwo gukora firime, guhuza no gufatira hamwe bituma bukoreshwa muburyo butandukanye mubiribwa, imiti, impapuro, imyenda nubucukuzi. Ubwiza bwibisubizo bya CMC burashobora kugenzurwa nibintu byinshi, nko kwibanda, DS, MW, ubushyuhe, na pH, kandi birashobora kurangwa nimyitwarire ya pseudoplastique hamwe nogukata imisatsi. CMC igira ingaruka nziza ku bwiza, gukora neza no kuramba kw'ibicuruzwa n'ibikorwa, bigatuma iba igice cy'inganda zigezweho.
