Phapano ke efe lipakeng tsa sodium CMC le CMC?

Sodium carboxymethylcellulose (NaCMC) le carboxymethylcellulose (CMC) ka bobeli li tsoa ho cellulose, polymer ea tlhaho e fumanehang maboteng a lisele tsa semela.Metsoako ena e sebelisoa liindastering tse fapaneng, ho kenyeletsoa lijo, meriana, masela le tse ling.

Sodium Carboxymethylcellulose (NaCMC):

1. Sebopeho sa lik'hemik'hale:

NaCMC e ntšoa ho selulose ka mokhoa oa ho fetola lik'hemik'hale.Lihlopha tsa Carboxymethyl (-CH2-COOH) li kenngoa ka har'a sebopeho sa cellulose, 'me li-ion tsa sodium li amahanngoa le lihlopha tsena.
Letsoai la sodium la CMC le fana ka ho qhibiliha ha metsi ho polymer.

2. Sollubility:

NaCMC e qhibiliha ka metsing 'me e etsa tharollo ea viscous.Ho ba teng ha li-ion tsa sodium ho eketsa ho qhibiliha ha eona metsing ha ho bapisoa le selulose e sa fetoloang.

3. Likarolo le mesebetsi:

E sebetsa e le setei, se tsitsitseng le se bolokang metsi lits'ebetsong tse fapaneng.
E bonts'a boitšoaro ba pseudoplastic kapa shear-thinning, ho bolelang hore viscosity ea eona e fokotseha tlas'a khatello ea ho kuta.

4. Kopo:

Indasteri ea Lijo: E sebelisoa e le ntho e matlafatsang lihlahisoa tsa lijo tse kang li-sauces, ice cream le lintho tse halikiloeng.

Pharmaceutical: E sebelisoamekhoeng ea eona ea ho tlama le ho ntlafatsa viscosity.

Ho cheka oli: ho sebelisoa ho laola viscosity le tahlehelo ea metsi marong a ho cheka.

5. Tlhahiso:

Synthesized ke karabelo ea cellulose ka sodium hydroxide le monochloroacetic acid.

Carboxymethylcellulose (CMC):

1. Sebopeho sa lik'hemik'hale:

CMC ka kutloisiso e pharaletseng e bolela mofuta oa carboxymethylated oa selulose.E ka ba kapa chee amanang le sodium ion.

Lihlopha tsa carboxymethyl li kenngoa mokokotlong oa cellulose.

2. Sollubility:

CMC e ka ba teng ka mefuta e mengata, ho kenyelletsa letsoai la sodium (NaCMC) le matsoai a mang a kang calcium CMC (CaCMC).

CMC sodium ke mokhoa o tloaelehileng haholo o qhibilihang ka metsing, empa ho latela kopo, CMC e ka boela ea fetoloa hore e se ke ea qhibiliha ka metsing.

3. Likarolo le functions:

E tšoana le NaCMC, CMC e nkoa e le ea bohlokoa ka lebaka la ho tiea, ho tsitsisa le ho boloka metsi.

Khetho ea CMC type (sodium, calcium, joalo-joalo) e itšetlehile ka thepa e lakatsehang ea sehlahisoa sa ho qetela.

4. Kopo:

E sebelisoa haholo indastering ea lijo, meriana, masela, lirafshoa le tlhahiso ea pampiri.

Sebopeho se fapanengsea CMC e ka khethoa ho latela litlhoko tse ikhethileng tsa kopo.

5. Tlhahiso:

Carboxymethylation ea cellulose e ka kenyelletsa maemo a fapaneng a karabelo le li-reagents, tse lebisang ho thehoeng ha mefuta e fapaneng ea CMC.

Phapang e kholo lipakeng tsa sodium CMC le CMC ke boteng ba li-ion tsa sodium.Sodium CMC e bua ka ho khetheha letsoai la sodium la carboxymethyl cellulose, le qhibilihang haholo metsing.Ka lehlakoreng le leng, CMC ke lentsoe le pharaletseng le akaretsang mefuta e fapaneng ea carboxymethylated cellulose, ho kenyelletsa le sodium le matsoai a mang, e 'ngoe le e' ngoe e na le thepa ea eona le lits'ebetso.Khetho lipakeng tsa sodium CMC le CMC e ipapisitse le ts'ebeliso e reriloeng le thepa e lakatsehang ea sehlahisoa sa ho qetela.
