Incamake
Cellulose ni polymer isanzwe igizwe na anhydrous β-glucose ibice, kandi ifite amatsinda atatu ya hydroxyl kuri buri mpeta y'ibanze.Muguhindura imiti ya selile, ibikomoka kuri selile bitandukanye bishobora kubyara umusaruro, kandi kimwe muribi ni selile.Cellulose ether ni polymer igizwe na ether yubatswe ikomoka kuri selile, harimo methyl selulose, Ethyl selulose, hydroxyethyl selulose, hydroxypropyl selulose, carboxymethyl selulose, nibindi.Ibikomokaho mubisanzwe bikorwa mugukora alkali selulose hamwe na monochloroalkane, okiside ya Ethylene, okiside ya propylene, cyangwa aside monochloroacetic.Ether ya selile ivamo ifite amazi meza cyane, ubushobozi bwo kubyimba, hamwe no gukora firime, kandi ikoreshwa cyane mubikorwa nkubwubatsi, imiti, ibiryo, na cosmetike.Cellulose ether ni ibintu bishobora kuvugururwa, ibinyabuzima bishobora kwangirika, kandi bidafite uburozi, bigatuma bikoreshwa muburyo bukoreshwa na polimeri yubukorikori.
Imikorere n'ibiranga
1. Ibiranga isura
Cellulose ether ni ifu yera, idafite impumuro nziza, ifu ya fibrous ifata byoroshye ubuhehere kandi ikora colloide ihamye, igaragara neza, ibonerana iyo ikozwe mumazi.
2. Gushinga firime no gufatira hamwe
Guhindura imiti ya selile kugirango itange selile ether igira ingaruka zikomeye kumiterere yayo, harimo gukomera kwayo, ubushobozi bwo gukora firime, imbaraga zubusabane, hamwe no kurwanya umunyu.Ibiranga bituma selile ya ether yifuzwa cyane polymer ifite imbaraga zubukanishi, guhinduka, kurwanya ubushyuhe, no kurwanya ubukonje.Byongeye kandi, irerekana guhuza neza na resin zitandukanye hamwe na plasitike, bigatuma ikoreshwa muburyo bwo gukora plastike, firime, langi, ibifunga, latx, nibikoresho byo gutwikira ibiyobyabwenge.Bitewe nuburyo butandukanye, selulose ether yabaye ibikoresho byingenzi mubikorwa byinganda, bitanga imikorere inoze, itajegajega, kandi biramba kubicuruzwa byinshi.Nkigisubizo, ifite uburyo bwinshi bwo gukoresha mubice bitandukanye, harimo imiti, imiti, imyenda, ubwubatsi, ninganda zibiribwa, nibindi.
3. Gukemura
Ububasha bwa ethers ya selile nka methylcellulose, methyl hydroxyethyl selulose, hydroxyethyl selulose, na sodium carboxymethyl hydroxyethyl selulose iratandukanye bitewe nubushyuhe hamwe na solvent ikoreshwa.Methylcellulose na methyl hydroxyethyl selulose irashobora gushonga mumazi akonje hamwe na solge zimwe na zimwe ariko bikagwa iyo bishyushye, hamwe na methylcellulose igwa kuri 45-60 ° C hamwe na methyl hydroxyethyl selulose ivanze kuri 65-80 ° C.Nyamara, imvura irashobora kongera gushonga mugihe ubushyuhe bwagabanutse.Ku rundi ruhande, hydroxyethyl selulose na sodium carboxymethyl hydroxyethyl selulose irashobora gukama amazi ku bushyuhe ubwo aribwo bwose ariko ntibishobora gushonga mumashanyarazi.Ethers ya selulose ifite solubile zitandukanye nubushyuhe bwimvura ituma bikenerwa mubikorwa bitandukanye mubikorwa nka plastiki, firime, ibifuniko, hamwe nibifatika.
4. Kubyimba
Iyo selulose ether ishonga mumazi, ikora igisubizo cya colloidal ifite viscosity iterwa nurwego rwa polymerisation ya selile ya ether.Igisubizo kirimo macromolecules hydrated yerekana imyitwarire itari Newtonian, ni ukuvuga, imyitwarire yimyitwarire ihinduka hamwe nimbaraga zikoreshwa.Bitewe na macromolecular imiterere, ubwiza bwumuti bwiyongera vuba hamwe nibitekerezo, ariko bigabanuka vuba hamwe nubushyuhe bwiyongera.Ubwiza bwa selile ether ibisubizo nabyo biterwa na pH, imbaraga za ionic, no kuba hari indi miti.Iyi miterere yihariye ya selulose ether ituma igira akamaro mubikorwa bitandukanye nka adhesives, coatings, cosmetics, nibicuruzwa byibiribwa.
Gusaba
1. Inganda zikomoka kuri peteroli
Sodium carboxymethyl selulose (NaCMC) ni selile ya selile ifite uburyo bwinshi bwo gukoresha mugikorwa cyo gukuramo amavuta.Ubwiza bwayo bwiyongera cyane kandi butakaza igihombo kigabanya guhitamo gukundwa cyane mugucukura amazi, sima ya sima, no kuvunika amazi.By'umwihariko, yerekanye ibisubizo bitanga umusaruro mukuzamura peteroli.NaCMC irashobora kurwanya umwanda utandukanye w’umunyu kandi ikongera amavuta mu kugabanya igihombo cy’amazi, kandi kurwanya umunyu hamwe n’ubushobozi bwo kongera ubukana bituma biba byiza gutegura amazi yo gucukura amazi meza, amazi yo mu nyanja, n’amazi yuzuye umunyu.
Sodium carboxymethyl hydroxypropyl selulose (NaCMHPC) na sodium carboxymethyl hydroxyethyl selulose (NaCMHEC) ni selile ebyiri za selulose ether zikomoka ku muvuduko mwinshi, imikorere myiza yo kurwanya calcium, hamwe nubushobozi bwiza bwo kongera ububobere, bigatuma bahitamo neza nko gucukura ibyondo nibikoresho byifashishwa. gutegura amazi yuzuye.Bagaragaza ubushobozi buhebuje bwo kongera ubukana no gutakaza amazi bigabanya ibintu ugereranije na hydroxyethyl selulose, kandi ubushobozi bwabo bwo kubumbabumbwa mumazi yo gucukura yubucucike butandukanye munsi yuburemere bwa calcium chloride bituma bongerwaho ibintu byinshi kugirango bongere umusaruro wamavuta.
Hydroxyethyl selulose (HEC) niyindi nkomoko ya selile ikoreshwa nkigikoresho cyo kubyimba ibyondo no gutuza mugikorwa cyo gucukura, kurangiza, na sima.Ugereranije na sodium carboxymethyl selulose na guar gum, HEC ifite ihagarikwa ryinshi ryumucanga, ubushobozi bwumunyu mwinshi, kurwanya ubushyuhe bwiza, kutavangavanga gake, gutakaza amazi make, hamwe no kumena gel.HEC yakoreshejwe cyane kubera ingaruka nziza yo kubyimba, ibisigara bike, nibindi bintu.Muri rusange, ether ya selile nka NaCMC, NaCMHPC, NaCMHEC, na HEC igira uruhare runini mugikorwa cyo gucukura peteroli kandi byagaragaje imbaraga zikomeye mukuzamura peteroli.
2. Inganda zubaka no gusiga amarangi
Sodium carboxymethyl selulose ninyongera yibikoresho byubaka bishobora gukoreshwa nka retarder, umukozi wo kubika amazi, kubyimbye no guhambira kubaka masoni na pompe.Irashobora kandi gukoreshwa nkibikoresho bitatanya, bigumana amazi kandi ikabyimbye kubikoresho bya pompa, minisiteri nubutaka.Ububiko bwihariye bwa pompe na plaster buvanze bikozwe muri carboxymethyl selulose birashobora kunoza imikorere, kubika amazi no kurwanya ibimeneka, birinda gucika nubusa mu rukuta.Byongeye kandi, methyl selulose irashobora gukoreshwa mugukora ibikoresho byo gutunganya ibidukikije byubaka ibidukikije hejuru yurukuta rwo hejuru hamwe namabuye ya tile hejuru, ndetse no gushushanya hejuru yinkingi ninzibutso.
3. Inganda zikora imiti ya buri munsi
Sodium carboxymethyl selulose ni ibintu byinshi bihindura viscosifier ishobora gukoreshwa mubicuruzwa bitandukanye.Mubicuruzwa bya paste birimo ibikoresho byifu byifu, bigira uruhare runini mukwirakwiza no guhagarika ihagarikwa.Amavuta yo kwisiga yamazi cyangwa emuliyoni, ikora nkumubyimba, gutatanya, hamwe na homogenizing agent.Iyi nkomoko ya selile irashobora kandi gukora nka stabilisateur ya emulsiyo, amavuta na shampoo kubyimbye hamwe na stabilisateur, stabilisateur yinyo yinyo, hamwe na detergent kubyimbye no kurwanya imiti.Sodium carboxymethyl hydroxypropyl selulose, ubwoko bwa selile ether, ikoreshwa cyane nka stabilisateur yinyo yinyo kubera imiterere ya thixotropique, ifasha kugumana amenyo yinyo no guhoraho.Iyi nkomoko kandi irwanya umunyu na aside, bigatuma iba umubyimba mwiza mu bikoresho byangiza no kurwanya imiti.Sodium carboxymethyl selulose ikoreshwa muburyo bwo gukwirakwiza umwanda, kubyimbye, no gutatanya mugukora ifu yo kumesa hamwe nogukoresha amazi.
4. Ubuvuzi n'inganda
Mu nganda zimiti, Yibang hydroxypropyl carboxymethylcellulose (HPMC) ikoreshwa cyane nkibiyobyabwenge byangiza imiti yo mu kanwa irekurwa kandi ikanategura kurekura.Ikora nk'ibikoresho byo kurekura bigenga irekurwa ry'ibiyobyabwenge, kandi nk'ibikoresho byo gutwikira gutinda kurekura.Methyl carboxymethyl selulose na Ethyl carboxymethyl selulose ikoreshwa mugukora ibinini na capsules, cyangwa kwambara ibinini bisize isukari.Mu nganda z’ibiribwa, ether yo mu rwego rwo hejuru ya selile ni nziza cyane, stabilisateur, ibicuruzwa, ibikoresho bigumana amazi hamwe nubukanishi bwa fenike mu biribwa bitandukanye.Methylcellulose na hydroxypropylmethylcellulose bifatwa nk'imikorere ya metabolically kandi bifite umutekano mukoresha.Carboxymethylcellulose ifite isuku nyinshi irashobora kongerwa mubicuruzwa byibiribwa, birimo amata na cream, condiments, jama, jelly, ibiryo byabitswe, sirupe yameza, n'ibinyobwa.Byongeye kandi, carboxymethyl selulose irashobora gukoreshwa mugutwara no guhunika imbuto nshya nkigipfunyika cya plastiki, gitanga ingaruka nziza yo kubika neza, umwanda muke, nta byangiritse, hamwe n’umusaruro woroshye.
5. Ibikoresho bikora neza n'amashanyarazi
Ether-isukari nyinshi ya selile hamwe na aside nziza hamwe no kurwanya umunyu ikora nka stabilisateur ya electrolyte ikomeza, itanga imiterere ihamye ya colloidal kuri bateri ya alkaline na zinc-manganese.Ethers zimwe na zimwe za selile zerekana ubushyuhe bwa termotropique, nka hydroxypropyl selulose acetate, ikora kristu ya cholesteric iri munsi ya 164 ° C.
Ibyingenzi
Inkoranyamagambo y'ibintu bya shimi.
