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 sebetsa 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 mofuta o atileng haholo o qhibilihang ka metsing, empa ho latela ts'ebeliso, 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 cellulose ea carboxymethylated, ho kenyeletsoa 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.
