Ni gute wakora CMC Sodium Carboxymethyl Cellulose?

Selulose ya sodium carboxymethyl (CMC)ni ubwoko bwa cellulose bukomoka kuri karboxymethyl, buzwi kandi nka cellulose gum, kandi ni yo ionic cellulose gum y'ingenzi cyane. Ubusanzwe CMC ni imvange ya anionic polymer iboneka binyuze mu guhuza cellulose karemano na aside caustic alkali na monochloroacetic. Uburemere bwa molekile y'iyi mvange buri hagati ya miliyoni icumi na miliyoni nyinshi.

【Imiterere】Ifu yera, nta mpumuro, ishongeshwa mu mazi kugira ngo ikore umuti utose cyane, idashongeshwa muri ethanol n'ibindi bishongeshwa.

【Ikoreshwa】Ifite inshingano zo gusunika no gukurura, guhuza neza no kurwanya umunyu, kandi izwi nka "monosodium glutamate y'inganda", ikoreshwa cyane.

Itegurwa rya CMC

Dukurikije uburyo butandukanye bwo gukwirakwiza amazi, umusaruro wa CMC mu nganda ushobora kugabanywamo ibice bibiri: uburyo bushingiye ku mazi n'uburyo bushingiye ku binyabutabire. Uburyo bwo gukoresha amazi nk'uburyo bwo gusubiza bwitwa uburyo bwo gutwara amazi, bukoreshwa mu gukora CMC y'ibinyabutabire ifite alkaline na CMC y'ibinyabutabire ifite urwego rwo hasi; uburyo bwo gukoresha organic solvent nk'uburyo bwo gusubiza bwitwa uburyo bwo gusubiza, bukwiriye mu gukora CMC y'ibinyabutabire ifite urwego rwo hejuru n'uruciriritse. Ibi bikorwa byombi mu cyuma gikurura amazi, kiri mu gikorwa cyo gukurura amazi kandi ni bwo buryo bw'ingenzi bwo gukora CMC muri iki gihe.

uburyo bushingiye ku mazi

Uburyo bwo gukurura amazi ni uburyo bwakozwe mbere mu nganda, aho ni ugukora ibikoresho bya selulose ya alkali hakoreshejwe uburyo bwo gushyushya amazi mu gihe cy’amazi arimo alkali n’amazi. Mu gihe cyo gukurura no gushyushya amazi, nta buryo bw’ibinyabuzima buba muri sisitemu. Ibikenewe mu bikoresho byo mu buryo bwo gukurura amazi biroroshye, nta shoramari rihagije kandi igiciro kiri hasi. Ingorane ni uko nta buryo bwinshi bwo gukurura amazi buhagije, kandi ubushyuhe buterwa n’uburyo bwo gushyushya amazi byongera ubushyuhe, ibyo bigatuma umuvuduko w’uburyo bwo gushyushya amazi ugabanuka kandi ubwiza bw’ibicuruzwa bukaba bubi. Ubu buryo bukoreshwa mu gutegura ibikoresho bya CMC byo mu rwego rwo hagati n’urwo hasi, nk’isabune, ibikoresho bipima imyenda, nibindi.

uburyo bwo gushongesha

Uburyo bwo gushonga buzwi kandi nka "organic solvent method". Ikintu nyamukuru kiyiranga ni uko "alkalization" na "etherification reactions" bikorwa mu gihe "organic solvent" ikoreshwa nk'uburyo bwo gusubiza (diluent). Dukurikije ingano y'uburyo bwo gushonga, igabanyijemo uburyo bwo gukaranga n'uburyo bwo gusya. Uburyo bwo gushonga ni bumwe n'uburyo bwo gusubiza mu buryo bw'amazi, kandi bugizwe n'ibyiciro bibiri byo gushonga no gusya, ariko uburyo bwo gusubiza muri ibi byiciro byombi buratandukanye. Uburyo bwo gushonga bukuraho inzira zikoreshwa mu buryo bw'amazi, nko kuvoma, gukamura, gusya, gusaza, nibindi, kandi "alkalization" na "etherification" byose bikorwa mu cyuma gikaranga. Ingorane ni uko uburyo bwo kugenzura ubushyuhe ari buke, umwanya n'igiciro biri hejuru. Birumvikana ko kugira ngo hakorwe ibikoresho bitandukanye, ni ngombwa kugenzura neza ubushyuhe bwa sisitemu, igihe cyo kugaburira, nibindi, kugira ngo ibicuruzwa bifite ubwiza n'imikorere myiza bishobore gutegurwa. Imbonerahamwe y'imigendekere yabyo igaragara ku Ishusho ya 2.

Uko itegurwa rya Sodiyumu rihagazeSelilulose ya karboksimetilibiva mu bikomoka ku buhinzi

Ibikomoka ku bihingwa bifite imiterere yo gutandukana no kuboneka byoroshye, kandi bishobora gukoreshwa cyane nk'ibikoresho fatizo byo gutegura CMC. Kuri ubu, ibikoresho fatizo bya CMC ahanini ni selulosi nziza, harimo fibre y'ipamba, fibre y'imyumbati, fibre y'ibyatsi, fibre y'imigano, fibre y'ingano, n'ibindi. Ariko, hamwe no gukomeza guteza imbere ikoreshwa rya CMC mu nzego zose z'ubuzima, hakurikijwe umutungo kamere usanzwe ukoreshwa mu gutunganya ibikoresho fatizo, uburyo bwo gukoresha ibikoresho fatizo bihendutse kandi binini mu gutegura CMC nta kabuza bizaba ari ikintu cy'ingenzi.

Ishusho

Selulosi ya sodium carboxymethyl irashobora gukoreshwa nk'inyunganizi, flocculant, thickener, chelating agent, actif-retaining agent, kole, ingano, ibikoresho bikora filime, nibindi. Ikoreshwa cyane mu bikoresho by'ikoranabuhanga, uruhu, pulasitiki, icapiro, ceramics, ikoreshwa buri munsi mu bijyanye n'imiti n'ibindi, kandi kubera imikorere yayo myiza n'uburyo butandukanye bwo kuyikoresha, iracyakomeza guteza imbere amashami mashya yo kuyikoresha. Muri iki gihe, munsi yo gukwirakwizwa kw'igitekerezo cyo gukora imiti y'icyatsi kibisi, ubushakashatsi bw'abanyamahanga kuriCMCIkoranabuhanga ryo gutegura ryibanda ku gushakisha ibikoresho fatizo by’ibinyabuzima bihendutse kandi byoroshye kubona hamwe n’uburyo bushya bwo gutunganya CMC. Nk’igihugu gifite umutungo mwinshi w’ubuhinzi, igihugu cyanjye kiri mu ihinduka rya cellulose. Ku bijyanye n’ikoranabuhanga, gifite ibyiza by’ibikoresho fatizo, ariko hari n’ibibazo nko kudahuza mu gutegura biterwa n’amasoko atandukanye y’imigozi ya cellulose ya biomass hamwe n’itandukaniro rinini mu bice bigize. Haracyari ibibura mu ikoreshwa ry’ibikoresho bya biomass bihagije, bityo hakenewe gukorwa ubushakashatsi bwimbitse muri izi nzego.
