Carboxymethyl Cellulose （CMC）

ibisobanuro bigufi:

Kugeza ubu, tekinoroji yo guhindura selile yibanze cyane kuri etherification na esterification.Carboxymethylation ni ubwoko bwa tekinoroji ya etherification.Carboxymethyl selulose (CMC) iboneka na carboxymethylation ya selile, kandi igisubizo cyayo cyamazi gifite imirimo yo kubyimba, gushiraho firime, guhuza, kugumana ubushuhe, kurinda colloidal, emulisation no guhagarika, kandi ikoreshwa cyane mugukaraba, peteroli, ibiryo, imiti, imyenda n'impapuro nizindi nganda.Nimwe mubintu byingenzi bya selile.

Imikoreshereze y'ibicuruzwa

Carboxymethyl selulose (CMC) ni ifu yera idafite uburozi kandi idafite uburyohe kandi ikora neza kandi yoroshye gushonga mumazi.Igisubizo cyacyo cyamazi ntaho kibogamiye cyangwa alkaline ibonerana yamazi ya viscous fluid, igashonga mubindi bikoresho bifata amazi hamwe na resin, kandi ntibishobora gushonga mumashanyarazi nka Ethanol.CMC irashobora gukoreshwa nka binder, umubyimba, umukozi uhagarika, emulisiferi, ikwirakwiza, stabilisateur, ingero zingana, nibindi. Carboxymethyl selulose (CMC) numusaruro munini wa selile ya ether, ikoreshwa cyane, ibicuruzwa byoroshye, bizwi cyane nka " inganda MSG ".

Kwihuta

1. Sodium carboxymethyl selulose ni surfactant, ishobora gukoreshwa nka anti-fouling re-deposition, ikaba ikwirakwiza kandi ikanagabanya uduce duto duto, ikagira urwego rukomeye rwa adsorption kumurongo kugirango wirinde kongera kwiyongera kuri fibre .

2. Iyo sodium carboxymethyl selulose yongewe kumifu yo kumesa, igisubizo kirashobora gutatana kandi bikamenyekana byoroshye hejuru yibice bikomeye, bigakora urwego rwa hydrophilique adsorption ikikije ibice bikomeye.Noneho ubusumbane bwubuso hagati yamazi nuduce twinshi ntiburi munsi yubushyuhe bwo hejuru imbere mubice bikomeye, kandi ingaruka zo guhanagura za molekile ya surfactant zangiza ubumwe hagati yibice bikomeye.Ibi bikwirakwiza umwanda mumazi.

3. Sodium carboxymethyl selulose yongewe kumafu yo kumesa, igira ingaruka.Nyuma yo kwigana igipimo cyamavuta, ntabwo byoroshye kwegeranya no kugwa kumyenda.

4. Sodium carboxymethyl selulose yongewemo ifu yo kumesa, igira ingaruka zo guhanagura kandi ishobora kwinjira mumyanda ya hydrophobique, ikamenagura uduce twumwanda mo uduce duto twa colloidal, kugirango umwanda byoroshye kuva muri fibre.

Kongera ibiryo

CMC ikoreshwa cyane mu nganda z’ibiribwa, mu binyobwa bitandukanye by’amata, ibiryo, bigira uruhare mu kubyimba, gutuza no kunoza uburyohe, muri ice cream, umutsima na paste, noode ihita hamwe na paste ako kanya nibindi biribwa, bigira uruhare yo gukora, kunoza uburyohe, kugumana amazi, kongera ubukana nibindi.Muri byo, FH9, FVH9, FM9 na FL9 bifite aside irike.Ibicuruzwa byongewe hejuru bifite ibyiza byo kubyimba.CMC irashobora gukemura neza ikibazo cyo gutandukana-gutemba no kugabanuka kwibinyobwa bya acide lactique mugihe proteine irenze 1%, kandi irashobora gutuma amata ya acide lactique agira uburyohe bwiza.Amata y’amata yakozwe arashobora kugumana ituze muri PH ya 3.8-4.2, irashobora kwihanganira pasteurisation na 135 process uburyo bwo guhagarika ako kanya, ubwiza bwibicuruzwa burahagaze neza kandi bwizewe, kandi burashobora kubikwa mubushyuhe busanzwe mumezi arenga atandatu.Intungamubiri zumwimerere nuburyohe bwa yogurt ntigihinduka.Ice cream hamwe na CMC, irashobora gukumira imikurire ya kristu ya ice, kugirango ice cream iryoshye cyane mugihe urya, nta gufatana, amavuta, ibinure biremereye nubundi buryohe bubi.Byongeye kandi, igipimo cyo kubyimba ni kinini, kandi kurwanya ubushyuhe no kurwanya gushonga nibyiza.CMC kumasafuriya ako kanya ituma isafuriya ihita igira ubukana bwiza, uburyohe bwiza, imiterere yuzuye, ubwinshi bwisupu yisupu, kandi irashobora no kugabanya amavuta (hafi 20% ugereranije no gukoresha lisansi yambere).

Ubwoko bwera cyane

Impapuro zo mu rwego rwa CMC zikoreshwa mu bunini bw'impapuro, ku buryo impapuro zifite ubucucike bwinshi, ubwiza bwa wino nziza, bushobora kunonosora imikoranire hagati ya fibre imbere mu mpapuro, bityo bikazamura impapuro no guhangana n’ububiko.Kunoza imbere yimpapuro, kugabanya umukungugu wo gucapa mugihe cyo gucapa, cyangwa nta mukungugu.Ubuso bwimpapuro kugirango ubone kashe nziza hamwe namavuta yo kunoza ubuziranenge bwo gucapa.Ubuso bwimpapuro bwongera urumuri, bugabanya ububobere, kandi bugira uruhare mukubungabunga amazi.Ifasha gukwirakwiza pigment, kuramba kuramba, no gutanga amazi meza, imiterere ya optique hamwe no gucapura imiterere yo guhuza ibintu byinshi.

Icyiciro cy'amenyo

CMC ifite pseudoplastique nziza, thixotropy na nyuma yo gukura.Umuti wamenyo wamenyo urahamye, guhoraho birakwiriye, guhinduka nibyiza, umuti wamenyo ntuhira amazi, ntusiba, ntukonje, paste irasa kandi yoroshye, yoroshye, kandi irwanya ihindagurika ryubushyuhe.Guhuza neza nibikoresho bitandukanye bibisi muri menyo yinyo;Irashobora kugira uruhare runini mugushiraho, guhuza, kuvomera no gutunganya impumuro nziza.

Umwihariko kubumba

Mubikorwa byubutaka, bikoreshwa muburyo bukoreshwa mu isoro rya ceramic, paste glaze na glaze.Icyiciro cya Ceramic CMC ikoreshwa nkibikoresho byubusa muri bilet ceramic kugirango wongere imbaraga na plastike ya bilet.Kunoza umusaruro.Muri ceramic glaze, irashobora gukumira imvura igwa ya glaze, igahindura ubushobozi bwo gufatana na glaze, kunoza guhuza glaze yubusa no kunoza imbaraga zurwego rwa glaze.Ifite uburyo bwiza bwo gutembera no gukwirakwizwa mu icapiro rya glaze, ku buryo icapiro ryacapye rihamye kandi rimwe.

Ikibanza cyihariye cya peteroli

Ifite ibiranga molekile imwe isimburana, isuku nyinshi hamwe na dosiye nkeya, bishobora kunoza imikorere yicyondo.Kurwanya ubuhehere bwiza, kurwanya umunyu no kurwanya alkaline, bikwiranye no kuvanga no gukoresha amazi yumunyu wuzuye hamwe ninyanja.Birakwiriye gutegura ifu nigihe gito cyo kubyimba murwego rwo gukoresha amavuta.Cellulose ya polyanionic (PAC-HV) ni viscosifier ikora neza kandi itanga umusaruro mwinshi hamwe nubushobozi bwo kugabanya gutakaza amazi mubyondo.Polyanionic selulose (PAC-LV) nigabanuka ryamazi meza yo kugabanya ibyondo, ikaba ifite uburyo bwiza bwo kugenzura amazi yatakaje ibyondo byo mumazi hamwe nicyondo cyuzuye amazi yumunyu.Bikwiranye na sisitemu ya sisitemu igoye kugenzura ibintu bikomeye hamwe nimpinduka nini.CMC, nk'amazi avunika ya gele, ifite ibiranga gelatinable nziza, umusenyi ukomeye wo gutwara, ubushobozi bwo kumena reberi hamwe n'ibisigara bike.
