1. Muri make Intangiriro ya Carboxymethyl Cellulose
Izina ry'icyongereza: Carboxyl methyl Cellulose
Amagambo ahinnye: CMC
Inzira ya molekile irahinduka: [C6H7O2 (OH) 2CH2COONa] n
Kugaragara: ifu yera cyangwa yoroheje yumuhondo fibrous granular ifu.
Amazi meza: gushonga byoroshye mumazi, bigakora colloid igaragara neza, kandi igisubizo kidafite aho kibogamiye cyangwa alkaline nkeya.
Ibiranga: Ibice byinshi bya molekuline yubuso bukora colloid, impumuro nziza, uburyohe kandi ntabwo ari uburozi.
Cellulose isanzwe ikwirakwizwa cyane muri kamere kandi ni polysaccharide nyinshi.Ariko mu musaruro, selile isanzwe ibaho muburyo bwa sodium carboxymethyl selulose, izina ryuzuye rero rigomba kuba sodium carboxymethyl selulose, cyangwa CMC-Na.Ikoreshwa cyane mu nganda, ubwubatsi, ubuvuzi, ibiryo, imyenda, ububumbyi nizindi nzego.
2. Tekinoroji ya Carboxymethyl selile
Guhindura tekinoroji ya selile irimo: etherification na esterification.
Guhindura carboxymethyl selulose: reaction ya carboxymethylation muburyo bwa tekinoroji ya etherification, selile ni carboxymethylated kugirango ibone carboxymethyl selile, bita CMC.
Imikorere ya carboxymethyl selulose igisubizo cyamazi: kubyimba, gukora firime, guhuza, gufata amazi, kurinda colloid, emulisation no guhagarikwa.
3. Imiti ya carboxymethyl selulose
Cellulose alkalisation reaction:
[C6H7O2 (OH) 3] n + nNaOH → [C6H7O2 (OH) 2ONa] n + nH2O
Imyitwarire ya etherification ya acide monochloroacetic nyuma ya selile ya alkali:
[C6H7O2 (OH) 2ONa] n + nClCH2COONa → [C6H7O2 (OH) 2OCH2COONa] n + nNaC
Kubwibyo: formulaire yimiti yo gukora carboxymethyl selile ni: Cell-O-CH2-COONa NaCMC
Sodium carboxymethyl selulose.
4. Ibiranga ibicuruzwa biranga carboxymethyl selile
1. Kubika igisubizo cyamazi ya CMC: Irahagaze munsi yubushyuhe buke cyangwa urumuri rwizuba, ariko acide na alkalinity yumuti bizahinduka kubera ubushyuhe bwubushyuhe.Bitewe nimirasire ya ultraviolet cyangwa mikorobe, ibishishwa byumuti bizagabanuka cyangwa byangirika.Niba ububiko bwigihe kirekire busabwa, hagomba kongerwaho uburyo bwo kubungabunga ibidukikije.
2. Uburyo bwo gutegura igisubizo cyamazi ya CMC: kora ibice mbere bitose kimwe, bishobora kongera umuvuduko wo gusesa.
3. CMC ni hygroscopique kandi igomba kurindwa ubuhehere mugihe cyo kubika.
4. Umunyu uremereye cyane nka zinc, umuringa, gurş, aluminium, ifeza, icyuma, amabati, na chromium birashobora gutuma CMC igwa.
5. Imvura igwa mubisubizo byamazi biri munsi ya PH2.5, bishobora kugarurwa nyuma yo kutabogama wongeyeho alkali.
6. Nubwo umunyu nka calcium, magnesium nu munyu wameza bidafite ingaruka yimvura kuri CMC, bizagabanya ubukonje bwumuti.
7. CMC ihujwe nandi mavuta adashobora gukama amazi, koroshya hamwe na resin.
8. Bitewe no gutunganya ibintu bitandukanye, isura ya CMC irashobora kuba ifu nziza, ingano nini cyangwa fibrous, idafite aho ihuriye nibintu byumubiri nubumara.
9. Uburyo bwo gukoresha ifu ya CMC iroroshye.Irashobora kongerwamo no gushonga mumazi akonje cyangwa amazi ashyushye kuri 40-50 ° C.
5. Impamyabumenyi yo gusimbuza no gukomera kwa carboxymethyl selulose
Urwego rwo gusimbuza bivuga impuzandengo ya sodium carboxymethyl matsinda yometse kuri buri selile;agaciro ntarengwa k'urwego rwo gusimburwa ni 3, ariko ingirakamaro cyane mu nganda ni NaCMC ifite urwego rwo gusimbuza rutandukanye kuva 0.5 kugeza 1.2.Imiterere ya NaCMC ifite impamyabumenyi yo gusimbuza 0.2-0.3 iratandukanye cyane n'iya NaCMC ifite impamyabumenyi yo gusimbuza 0.7-0.8.Iyambere irashonga igice gusa mumazi pH 7, ariko iyanyuma irashonga rwose.Ibinyuranye nukuri mubihe bya alkaline.
6. Impamyabumenyi ya polymerisation hamwe nubwiza bwa carboxymethyl selulose
Impamyabumenyi ya polymerisation: bivuga uburebure bwurunigi rwa selile, igena ubwiza.Umwanya muremure wa selile, niko ubwinshi bwijimye, kandi nigisubizo cya NaCMC.
Viscosity: Igisubizo cya NaCMC ni amazi atari Newtonian, kandi bigaragara ko ububobere bwayo bugabanuka iyo imbaraga zogosha ziyongereye.Nyuma yo gukangura byahagaritswe, ubukonje bwiyongereye ugereranije kugeza bugumye buhamye.Nukuvuga ko igisubizo ari thixotropic.
7. Urutonde rwa carboxymethyl selulose
1. Inganda zubaka nubutaka
(1) Ibikoresho byubatswe: gutatanya neza, gukwirakwiza umwenda umwe;nta ntera, ituze ryiza;Ingaruka nziza yo kubyimba, guhinduranya ibishishwa.
(2) Inganda zubutaka: zikoreshwa nkibikoresho byubusa kugirango zongere plastike yibumba ryibumba;glaze.
2. Gukaraba, kwisiga, itabi, inganda zo gucapa no gusiga amarangi
(1) Gukaraba: CMC yongewe kumashanyarazi kugirango umwanda wogejwe ntuzongere gushira kumyenda.
(2) Amavuta yo kwisiga: kubyimba, gutatanya, guhagarika, gutuza, nibindi nibyiza gutanga umukino wuzuye kubintu bitandukanye byo kwisiga.

4. Inganda zoza amenyo
(1) CMC ifite guhuza neza nibikoresho bitandukanye bibisi mu menyo yinyo;
.
.
(4) Kurwanya ihinduka ryubushyuhe, kuvomera no gutunganya impumuro nziza.
(5) Kogosha bito no kudoda mumabati.
5. Inganda zibiribwa
.uburyohe bwiza nyuma yo gushonga mumazi;uburinganire bwiza bwo gusimbuza.
(2) Ice cream: Kora amazi, ibinure, proteyine, nibindi bikora kimwe, gitatanye kandi gihamye kugirango wirinde kristu.
.
(4) Isafuriya ako kanya: kongera ubukana no kwihanganira guteka;ifite imiterere myiza muri biscuits na pancake, kandi hejuru ya cake iroroshye kandi ntibyoroshye kumeneka.
(5) Ako kanya paste: nkibishishwa.
(6) CMC ni inert physiologique kandi idafite agaciro ka calorificateur.Kubwibyo, ibiryo bya karori nkeya birashobora kubyara umusaruro.
6. Inganda
CMC ikoreshwa mubunini bw'impapuro, ituma impapuro zigira ubucucike bwinshi, irwanya wino nziza yo kwinjira, gukusanya ibishashara binini kandi byoroshye.Muburyo bwo gusiga amabara, bifasha kugenzura ibizunguruka byamabara;irashobora kunonosora imiterere hagati ya fibre imbere yimpapuro, bityo igahindura imbaraga hamwe no kugabanuka kwimpapuro.
7. Inganda zikomoka kuri peteroli
CMC ikoreshwa mu gucukura peteroli na gaze, gucukura neza n'indi mishinga.
8. Abandi
Ibikoresho bifata inkweto, ingofero, amakaramu, nibindi, polish hamwe namabara kumpu, stabilisateur yo kuzimya umuriro wa furo, nibindi.
