Uyini umehluko phakathi kwe-sodium CMC ne-CMC?

I-sodium carboxymethylcellulose (NaCMC) kanye ne-carboxymethylcellulose (CMC) zombili ziphuma ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. Lezi zinhlanganisela zisebenza ezimbonini ezahlukahlukene, ezihlanganisa ukudla, ezemithi, izindwangu, nokunye.

I-Sodium Carboxymethylcellulose (NaCMC):

1.Isakhiwo samakhemikhali:

I-NaCMC ikhishwa ku-cellulose ngenqubo yokuguqulwa kwamakhemikhali. Amaqembu e-Carboxymethyl (-CH2-COOH) angeniswa esakhiweni se-cellulose, futhi ama-ion e-sodium ahlotshaniswa nalawa maqembu.
Usawoti we-sodium we-CMC unikeza ukuncibilika kwamanzi ku-polymer.

2. Ukunyibilika:

I-NaCMC iyancibilika emanzini futhi yenza isixazululo se-viscous. Ukuba khona kwe-sodium ion kuthuthukisa ukuncibilika kwayo emanzini uma kuqhathaniswa ne-cellulose engashintshiwe.

3. Izici nemisebenzi:

Isebenza njenge-thickener, stabilizer kanye ne-ejenti egcina amanzi ezinhlelweni ezahlukahlukene.
Ibonisa i-pseudoplastic noma i-shear-thinning, okusho ukuthi i-viscosity yayo iyancipha ngaphansi kwengcindezi yokugunda.

4. Isicelo:

Imboni Yokudla: Isetshenziswa njenge-ejenti yokujiya emikhiqizweni yokudla efana namasoso, u-ayisikhilimu kanye nezimpahla ezibhakwayo.

Ezemithi: Isetshenzisiweekwakhiweni kwezakhiwo zayo zokubopha kanye nezithuthukisa i-viscosity.

Ukumba uwoyela: kusetshenziselwa ukulawula i-viscosity nokulahlekelwa kwamanzi oketshezini lokumba.

5. Ukukhiqiza:

Ihlanganiswe ukusabela kwe-cellulose nge-sodium hydroxide ne-monochloroacetic acid.

I-Carboxymethylcellulose (CMC):

1.Isakhiwo samakhemikhali:

I-CMC ngomqondo obanzi ibhekisela kuhlobo lwe-carboxymethylated lwe-cellulose. Kungaba noma kungenzekiehlobene ne-sodium ions.

Amaqembu e-Carboxymethyl angeniswa kumgogodla we-cellulose.

2. Ukunyibilika:

I-CMC ingaba khona ngezindlela eziningi, okuhlanganisa usawoti we-sodium (NaCMC) namanye ama-salts afana ne-calcium CMC (CaCMC).

I-CMC sodium iwuhlobo oluvame kakhulu lokuncibilika emanzini, kodwa kuye ngohlelo lokusebenza, i-CMC ingabuye ilungiswe ukuze ingancibiliki kancane emanzini.

3. Izici kanye functiOs:

Kufana ne-NaCMC, CMI-C ibaluleke kakhulu ngokujiya kwayo, ukuzinzisa, kanye nezindawo ezigcina amanzi.

Ukukhethwa kwe-CMC type (i-sodium, i-calcium, njll.) incike ezintweni ezifunwayo zomkhiqizo wokugcina.

4. Isicelo:

Isetshenziswa kabanzi embonini yokudla, ekhemisi, endwangu, e-ceramics nasekukhiqizeni iphepha.

Ifomu elihlukilesye-CMC ingakhethwa ngokuya ngezidingo ezithile zohlelo lokusebenza.

5. Ukukhiqiza:

I-Carboxymethylation ye-cellulose ingase ihlanganise izimo ezihlukahlukene zokusabela nama-reagents, okuholela ekwakhekeni kwezinhlobo ezahlukene ze-CMC.

Umehluko omkhulu phakathi kwe-sodium CMC ne-CMC ubukhona be-sodium ions. I-Sodium CMC ibhekise ngqo kusawoti we-sodium we-carboxymethyl cellulose, oncibilika kakhulu emanzini. I-CMC, ngakolunye uhlangothi, igama elibanzi elihlanganisa izinhlobo ezahlukene ze-carboxymethylated cellulose, kuhlanganise ne-sodium namanye ama-salts, ngalinye linesethi yalo yezakhiwo kanye nezicelo. Ukukhetha phakathi kwe-sodium CMC ne-CMC kuncike ekusetshenzisweni okuhlosiwe kanye nezakhiwo ezifiswayo zomkhiqizo wokugcina.
