Nigute wakora CMC Sodium Carboxymethyl Cellulose?

Sodium carboxymethyl selulose (CMC)ni carboxymethylated ikomoka kuri selile, izwi kandi nka selulose gum, kandi nigifu cya ionic selile. Ubusanzwe CMC ni ifumbire ya anionic polymer iboneka mugukora selile naturel hamwe na caustic alkali na acide monochloroacetic. Uburemere bwa molekile yikomatanya buva kuri miriyoni mirongo kugeza kuri miliyoni nyinshi.

【Ibyiza powder Ifu yera, idafite impumuro nziza, gushonga mumazi kugirango ibe igisubizo cyinshi cyijimye, kidashonga muri Ethanol nandi mashanyarazi.

【Gushyira mu bikorwa】 Ifite imirimo yo guhagarika no guhumeka, guhuza neza no kurwanya umunyu, kandi izwi nka "inganda monosodium glutamate", ikoreshwa cyane.

Gutegura CMC

Ukurikije uburyo butandukanye bwa etherification, umusaruro winganda za CMC urashobora kugabanywamo ibyiciro bibiri: uburyo bushingiye kumazi nuburyo bushingiye kumashanyarazi. Uburyo bwo gukoresha amazi nkuburyo bwo kubyitwaramo bwitwa uburyo butwarwa namazi, bukoreshwa mukubyara alkaline iciriritse na CMC yo mu rwego rwo hasi; uburyo bwo gukoresha ibishishwa kama nkibisubizo byitwa uburyo bwa solvent, bukwiranye no kubyara CMC yo mu rwego rwo hejuru kandi yo mu rwego rwo hejuru. Izi reaction zombi zikorwa mumashanyarazi, arizo nzira yo guteka kandi nuburyo nyamukuru bwo kubyara CMC muri iki gihe.

uburyo bushingiye ku mazi

Uburyo butwarwa namazi nuburyo bwambere bwo gukora inganda, aribwo buryo bwo gukora alkali selulose hamwe na agent ya etherifingi mumiterere ya alkali nubusa. Mugihe cya alkalisation na etherification, nta sisitemu ngenga ibaho muri sisitemu. Ibikoresho bisabwa muburyo butwarwa namazi biroroshye cyane, hamwe nishoramari rito hamwe nigiciro gito. Ikibi ni uko habura kubura amazi menshi, kandi ubushyuhe buterwa na reaction byongera ubushyuhe, bwihutisha umuvuduko wibisubizo byuruhande, bikavamo imikorere ya etherifike nkeya hamwe nubuziranenge bwibicuruzwa. Ubu buryo bukoreshwa mugutegura ibicuruzwa bya CMC byo hagati kandi biri hasi, nkibikoresho byoza, ibikoresho bingana imyenda, nibindi.

uburyo bwo kwishyura

Uburyo bwa solvent buzwi kandi nkuburyo bwa organic solvent. Ikintu nyamukuru kiranga ni uko alkalisation na etherification reaction ikorwa hashingiwe ko umusemburo wa organic ukoreshwa nkibisubizo (diluent). Ukurikije ingano ya reaction diluent, igabanijwe muburyo bwo gukata hamwe nuburyo bworoshye. Uburyo bwo gukemura ni kimwe nuburyo bwo kwitwara bwuburyo bushingiye kumazi, kandi bugizwe kandi nibyiciro bibiri bya alkalisation na etherification, ariko uburyo bwo kubyitwaramo muribi byiciro byombi buratandukanye. Uburyo bwa solvent bukuraho inzira zirangwa muburyo bushingiye kumazi, nko gushiramo, gukanda, guhindagura, gusaza, nibindi, kandi alkalisation na etherification byose bikorerwa mukabuto. Ingaruka ni uko kugenzura ubushyuhe ari muke, ibisabwa umwanya hamwe nigiciro ni kinini. Birumvikana ko, kugirango habeho umusaruro wibikoresho bitandukanye, birakenewe kugenzura neza ubushyuhe bwa sisitemu, igihe cyo kugaburira, nibindi, kugirango ibicuruzwa bifite ubuziranenge nibikorwa byiza birashobora gutegurwa. Imbonerahamwe yimikorere yayo irerekanwa mumashusho 2.

Imiterere yo Gutegura SodiumCarboxymethyl Cellulosebiva mu buhinzi Ibicuruzwa

Ibihingwa by-ibicuruzwa bifite ibiranga ibintu bitandukanye kandi byoroshye kuboneka, kandi birashobora gukoreshwa cyane nkibikoresho fatizo byo gutegura CMC. Kugeza ubu, ibikoresho by’ibanze bya CMC bitunganijwe cyane cyane bya selile, harimo fibre yipamba, fibre yimyumbati, fibre straw, imigano, fibre straw fibre, nibindi.

Outlook

Sodium carboxymethyl selulose irashobora gukoreshwa nka emulifisiyeri, flocculant, umubyimba, chelating agent, kugumana amazi, imiti ifata, ingero zingana, ibikoresho bikora firime, nibindi. Irakoreshwa cyane mubikoresho bya elegitoroniki, uruhu, plastike, icapiro, ceramika, ikoreshwa rya buri munsi Imiti nizindi nzego, kandi iracyakomeza guteza imbere imirima mishya. Muri iki gihe, mu gukwirakwiza cyane igitekerezo cyo gukora imiti y’icyatsi kibisi, ubushakashatsi bw’amahanga kuriCMCtekinoroji yo gutegura yibanda kubushakashatsi buhendutse kandi bworoshye-kubona ibikoresho fatizo byibinyabuzima nuburyo bushya bwo kweza CMC. Nkigihugu gifite umutungo munini w’ubuhinzi, igihugu cyanjye kiri mu guhindura selile Mu bijyanye n’ikoranabuhanga, gifite ibyiza by’ibikoresho fatizo, ariko hari n’ibibazo nko kudahuza gahunda yo kwitegura biterwa n’amasoko atandukanye ya fibre selile ya biomass ndetse n’itandukaniro rinini mu bice. Haracyariho ibitagenda neza muburyo bukwiye bwo gukoresha ibikoresho bya biyomass, bityo rero ibyagezweho muri utwo turere bigomba gukorwa ubushakashatsi bwimbitse
