Ndeupi musiyano uripo pakati pe sodium CMC neCMC?

Sodium carboxymethylcellulose (NaCMC) uye carboxymethylcellulose (CMC) ese ari maviri anobva ku cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro.Mishonga iyi ine mashandisirwo mumaindasitiri akasiyana, anosanganisira echikafu, emishonga, machira, nezvimwe.

Sodium Carboxymethylcellulose (NaCMC):

1.Chemical chimiro:

NaCMC inotorwa kubva muselulosi kuburikidza nemakemikari ekuchinja maitiro.Mapoka eCarboxymethyl (-CH2-COOH) anounzwa mune cellulose chimiro, uye sodium ion inosanganiswa nemapoka aya.
Iyo sodium munyu yeCMC inopa kunyungudika kwemvura kune polymer.

2. Solubility:

NaCMC inonyungudika mumvura uye inoumba viscous solution.Kuvapo kweiyo sodium ion kunowedzera kunyungudika kwayo mumvura zvichienzaniswa neserurosi isina kugadziriswa.

3. Zvimiro uye mabasa:

Inoshanda seyakakora, stabilizer uye mvura inochengetedza mumiriri mune akasiyana maapplication.
Inoratidza pseudoplastic kana shear-kuonda maitiro, zvichireva kuti viscosity yayo inodzikira pasi pekunetseka kwekugera.

4. Application:

Indasitiri yeChikafu: Inoshandiswa sechinhu chinokora muzvigadzirwa zvekudya zvakaita sesosi, ice cream uye zvinhu zvakabikwa.

Pharmaceutical: Yakashandiswamumagadzirirwo ayo anosunga uye viscosity-enhancing zvivakwa.

Kuchera mafuta: inoshandiswa kudzora viscosity uye kurasikirwa kwemvura mumvura yekuchera.

5. Kugadzirwa:

Yakagadzirwa nekuita kwe cellulose ine sodium hydroxide uye monochloroacetic acid.

Carboxymethylcellulose (CMC):

1.Chemical chimiro:

CMC mupfungwa yakafara inoreva iyo carboxymethylated fomu ye cellulose.Inogona kana kusavapozvinoenderana ne sodium ions.

Mapoka eCarboxymethyl anounzwa mumusana we cellulose.

2. Solubility:

CMC inogona kuvapo nenzira dzakawanda, kusanganisira sodium munyu (NaCMC) uye mamwe munyu senge calcium CMC (CaCMC).

CMC sodium ndiyo inonyanya kunyungudika mumvura, asi zvichienderana nekushandiswa, CMC inogonawo kuchinjwa kuti isanyanya kunyungudika mumvura.

3. Zvimiro uye functions:

Zvakafanana neNaCMC, CMC inokosheswa nekukora, kudzikamisa, uye kuchengetedza mvura.

Sarudzo yeCMC type (sodium, calcium, etc.) zvinoenderana nezvinodiwa zvechigadzirwa chekupedzisira.

4. Application:

Inoshandiswa zvakanyanya muindasitiri yechikafu, mishonga, machira, ceramics uye kugadzira mapepa.

Mafomu akasiyanasyeCMC inogona kusarudzwa zvichienderana nezvinodiwa zvekushandisa.

5. Kugadzirwa:

Carboxymethylation ye cellulose inogona kusanganisira akasiyana maitiro ekuita uye reagents, zvichitungamira mukuumbwa kwemhando dzakasiyana dzeCMC.

Musiyano mukuru pakati pe sodium CMC ne CMC kuvepo kwe sodium ions.Sodium CMC inonyatso reva sodium munyu wecarboxymethyl cellulose, inonyungudika zvakanyanya mumvura.CMC, kune rumwe rutivi, ishoko rakakura rinofukidza akasiyana marudzi e carboxymethylated cellulose, kusanganisira sodium nemamwe mamunyu, imwe neimwe iine seti yayo yezvivakwa uye mashandisirwo.Sarudzo pakati pesodium CMC neCMC inoenderana neyakagadzirirwa kushandiswa uye inodiwa zvimiro zvechigadzirwa chekupedzisira.
