Uyini umehluko phakathi kwe-CMC ne-cellulose?

I-Carboxymethylcellulose (CMC) kanye neselulosi womabili ama-polysaccharides anezakhiwo ezihlukene kanye nezicelo. Ukuqonda umehluko wabo kudinga ukuhlola izakhiwo zabo, izakhiwo, imvelaphi, izindlela zokukhiqiza, kanye nezicelo.

I-Cellulose:

1. Incazelo nesakhiwo:

I-Cellulose iyi-polysaccharide yemvelo eyakhiwe ngamaketanga aqondile amayunithi e-β-D-glucose axhunywe ngamabhondi e-β-1,4-glycosidic.

Iyingxenye eyinhloko yesakhiwo sezindonga zamaseli ezitshalo, enikeza amandla nokuqina.

2. Umthombo:

I-Cellulose iyinsada ngokwemvelo futhi ngokuyinhloko itholakala emithonjeni yezitshalo njengokhuni, ukotini nezinye izinto ze-fibrous.

3. Ukukhiqiza:

Ukukhiqizwa kwe-cellulose kuhilela ukukhipha i-cellulose ezitshalweni bese kuyicutshungulwa ngezindlela ezinjengokugaya ngamakhemikhali noma ukugaya ngomshini ukuze kutholwe ifayibha.

4. Ukusebenza:

Ngendlela yayo yemvelo, i-cellulose ayincibiliki emanzini nasezincibilikilweni eziningi eziphilayo.

Inamandla aphezulu okudonsa, okuyenza ifanele izinhlelo zokusebenza lapho amandla nokuqina kubaluleke kakhulu.

I-Cellulose i-biodegradable kanye nemvelo.

5. Isicelo:

I-Cellulose inezinhlelo zokusebenza ezihlukahlukene, okuhlanganisa ukukhiqizwa kwephepha nebhodi, izindwangu, amapulasitiki asekelwe ku-cellulose, futhi njengesengezo se-fiber yokudla.

I-Carboxymethylcellulose (CMC):

1. Incazelo nesakhiwo:

I-Carboxymethylcellulose (CMC) iphuma ku-cellulose lapho amaqembu e-carboxymethyl (-CH2-COOH) efakwa kumgogodla we-cellulose.

2. Ukukhiqiza:

I-CMC ivamise ukukhiqizwa ngokwelapha i-cellulose nge-chloroacetic acid ne-alkali, okuholela ekushintshweni kwamaqembu e-hydroxyl ku-cellulose ngamaqembu e-carboxymethyl.

3. Ukunyibilika:

Ngokungafani ne-cellulose, i-CMC iyancibilika emanzini futhi yenza isixazululo se-colloidal noma ijeli kuye ngokugxilisa ingqondo.

4. Ukusebenza:

I-CMC inazo zombili izakhiwo ze-hydrophilic kanye ne-hydrophobic, okuyenza ilungele ukusetshenziswa okuhlukahlukene emikhakheni yokudla, yezemithi kanye nezimboni.

Inamandla okwenza ifilimu futhi ingasetshenziswa njenge-thickener noma i-stabilizer.

5. Isicelo:

I-CMC isetshenziswa embonini yokudla njenge-thickener, stabilizer kanye ne-emulsifier emikhiqizweni efana no-ayisikhilimu kanye nezingubo zesaladi.

Kwezemithi, i-CMC isetshenziswa njengesihlanganisi ekwakhiweni kwamathebulethi.

Isetshenziswa ekulinganiseni nasekuqedeni izinqubo zemboni yendwangu.

umehluko:

1. Ukunyibilika:

I-Cellulose ayincibiliki emanzini, kuyilapho i-CMC incibilika emanzini. Lo mehluko ekuncibilikeni wenza i-CMC isebenze ngezindlela ezihlukahlukene kakhulu ezinhlotsheni zezinhlelo zokusebenza, ikakhulukazi ezimbonini lapho ukwakheka okusekelwe emanzini kukhethwa khona.

2. Inqubo yokukhiqiza:

Ukukhiqizwa kwe-cellulose kuhilela ukukhishwa nokucubungula okuvela ezitshalweni, kuyilapho i-CMC ihlanganiswa ngenqubo yokuguqulwa kwamakhemikhali ehlanganisa i-cellulose ne-carboxymethylation.

3. Isakhiwo:

I-Cellulose inesakhiwo esiqondile nesingenagatsha, kuyilapho i-CMC inamaqembu e-carboxymethyl axhunywe kumgogodla we-cellulose, enikeza isakhiwo esiguquliwe esinokuncibilika okuthuthukisiwe.

4. Isicelo:

I-Cellulose isetshenziswa kakhulu ezimbonini ezifana nephepha nezindwangu lapho amandla ayo nokungancibiliki kunikeza izinzuzo.

I-CMC, ngakolunye uhlangothi, isetshenziswa ezinhlobonhlobo zezimboni, ezihlanganisa ukudla, ezemithi nezimonyo, ngenxa yokuncibilika kwayo emanzini nokuguquguquka.

5. Izakhiwo zomzimba:

I-Cellulose yaziwa ngamandla ayo kanye nokuqina, okunomthelela ekuqineni kwesakhiwo sezitshalo.

I-CMC izuza njengefa ezinye izakhiwo ze-cellulose kodwa futhi inezinye, njengekhono lokwenza amajeli nezisombululo, inikeze ububanzi obubanzi bezinhlelo zokusebenza.

Nakuba i-cellulose ne-carboxymethyl cellulose inomsuka ofanayo, izakhiwo zabo ezihlukene kanye nezakhiwo ziholele ekusetshenzisweni okuhlukene ezimbonini ezahlukene. Amandla we-cellulose nokungancibiliki kungaba usizo kwezinye izimo, kuyilapho ukuncibilika kwamanzi kwe-CMC kanye nesakhiwo esishintshiwe siyenza isithako esibalulekile kuhlu lwemikhiqizo nokubunjwa.
