Carboxymethyl selulose (CMC) ni polymer ikoreshwa cyane mumazi ya elegitoronike ikoreshwa muburyo butandukanye mu nganda nk'ibiribwa, imiti, imiti yo kwisiga, n'imyenda.Gusenya CMC neza ningirakamaro kugirango ikoreshwe neza muruganda.
Gusobanukirwa CMC:
Carboxymethyl selulose ikomoka kuri selile, polymer karemano iboneka murukuta rwibimera.Ihingurwa no guhindura imiti ya selile binyuze mu kwinjiza amatsinda ya carboxymethyl ku miterere yayo.Ihinduka ritanga amazi ya selile, bigatuma CMC iba umubyimba mwiza, stabilisateur, hamwe na rheologiya ihindura mubikorwa bitandukanye.
Ibintu bigira uruhare mu iseswa rya CMC:
Ubushyuhe: CMC ishonga byoroshye mumazi ashyushye kuruta mumazi akonje.Kongera ubushyuhe byihutisha inzira yo guseswa bitewe na molekile yongerewe imbaraga ningufu za kinetic.
Imyivumbagatanyo: Gukangura cyangwa guhagarika umutima byorohereza ikwirakwizwa rya CMC kandi bigateza imbere imikoranire yabo na molekile y'amazi, byihuta guseswa.
pH: CMC ihagaze neza mugice kinini cya pH;icyakora, imiterere ya pH ikabije irashobora kugira ingaruka kubibazo byayo.Mubisanzwe, kutabogama kuri alkaline nkeya ya pH ishyigikira iseswa rya CMC.
Ingano ya Particle: Ubutaka bwiza CMC irashonga vuba kuruta ibice binini bitewe n'ubuso bwiyongereye buboneka kugirango habeho amazi.
Kwishyira hamwe: Kwibanda cyane kwa CMC birashobora gusaba igihe n'imbaraga nyinshi kugirango iseswe burundu.
Uburyo bwo gusesa CMC:
1. Uburyo bw'amazi ashyushye:
Inzira: Shyushya amazi hafi yo guteka (hafi 80-90 ° C).Buhoro buhoro shyiramo ifu ya CMC mumazi mugihe ukomeje.Komeza kubyutsa kugeza CMC isheshwe burundu.
Ibyiza: Amazi ashyushye yihutisha gushonga, bigabanya igihe gikenewe kugirango solubilisation yuzuye.
Ibitekerezo: Irinde ubushyuhe bukabije bushobora gutesha agaciro cyangwa guhindura imitungo ya CMC.
2. Uburyo bukonje bwamazi:
Inzira: Nubwo idakora neza nkuburyo bwamazi ashyushye, CMC irashobora gushonga mumazi akonje.Ongeramo ifu ya CMC mubushyuhe bwicyumba cyangwa amazi akonje hanyuma ubyuke cyane.Emera igihe kinini cyo gusenyuka ugereranije nuburyo bwamazi ashyushye.
Ibyiza: Birakwiriye kubisabwa aho ubushyuhe bwo hejuru butifuzwa cyangwa budashoboka.
Ibitekerezo: Bisaba igihe kinini no guhagarika umutima ugereranije nuburyo bwamazi ashyushye.
3. Uburyo bwo kubanziriza amazi:
Inzira: Mbere yo kuvanga CMC n'amazi make kugirango ukore paste cyangwa slurry.CMC imaze gutatana kimwe, buhoro buhoro ongeramo iyi paste kumazi menshi mugihe ukomeza.
Ibyiza: Iremeza ndetse no gukwirakwiza ibice bya CMC, birinda guhuzagurika no guteza imbere iseswa rimwe.
Ibitekerezo: Bisaba kugenzura neza paste ihoraho kugirango wirinde agglomeration.
4. Uburyo bwo kutabogama:
Inzira: Kuramo CMC mumazi hamwe na pH idafite aho ibogamiye cyangwa alkaline nkeya.Hindura pH ukoresheje acide acide cyangwa alkali ibisubizo kugirango uhindure CMC.
Ibyiza: ihinduka rya pH rirashobora kongera imbaraga za CMC, cyane cyane mubikorwa aho pH igira uruhare runini.
Ibitekerezo: Bisaba kugenzura neza pH kugirango wirinde ingaruka mbi kubicuruzwa byanyuma.
5. Uburyo bufashijwe na Solvent:
Inzira: Gabanya CMC mumashanyarazi akwiye nka Ethanol cyangwa isopropanol mbere yo kuyinjiza muri sisitemu y'amazi yifuza.
Ibyiza: Umuti ukomoka ku buhinzi ushobora gufasha mu gusesa CMC, cyane cyane mu bikorwa aho amazi yonyine adahagije.
Ibitekerezo: Urwego rusigaye rushobora gukurikiranwa neza kugirango hubahirizwe umutekano n’amabwiriza.
Inama zo gusesa neza CMC:
Koresha Amazi meza: Amazi meza atarimo umwanda arashobora kunoza iseswa rya CMC nubwiza bwibicuruzwa.
Igenzurwa ryongeweho: Buhoro buhoro ongeramo CMC mumazi mugihe ukangura kugirango wirinde guhuzagurika no kwemeza gutandukana kimwe.
Hindura ibintu: Kugerageza hamwe nibintu bitandukanye nkubushyuhe, pH, hamwe nubukangurambaga kugirango umenye uburyo bwiza bwo gusesa CMC.
Kugabanya Ingano ya Particle: Niba bishoboka, koresha ifu ya CMC yubutaka neza kugirango wihute.
Kugenzura ubuziranenge: Gukurikirana buri gihe inzira yo gusesa nibiranga ibicuruzwa byanyuma kugirango ukomeze ubuziranenge hamwe nubwiza.
Icyitonderwa cyumutekano: Kurikiza protocole yumutekano mugihe ukoresha CMC nindi miti ijyanye nayo kugirango ugabanye ingaruka kubakozi nibidukikije.
Ukurikije ubu buryo ninama, urashobora gusesa neza CMC kubikorwa bitandukanye byinganda nubucuruzi, ukemeza imikorere myiza nibicuruzwa byiza.
