Sodium Carboxymethyl cellulose ke eng?

Carboxymethylcellulose (CMC) ke motsoako oa lik'hemik'hale o feto-fetohang le o sebelisoang haholo o fumanehang liindastering tse fapaneng ka lebaka la thepa ea ona e ikhethang.Polymer ena e tsoa ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa limela.Carboxymethylcellulose e entsoe ka phetoho ea lik'hemik'hale tsa selulose ka ho hlahisoa ha lihlopha tsa carboxymethyl, tse ntlafatsang bokhoni ba eona ba ho qhibiliha ha metsi le botenya.

Sebopeho sa Limolek'hule le Tšimoloho

Carboxymethylcellulose e na le liketane tsa cellulose tse nang le lihlopha tsa carboxymethyl (-CH2-COOH) tse hokelletsoeng ho tse ling tsa lihlopha tsa hydroxyl ho likarolo tsa tsoekere.Tšimoloho ea CMC e kenyelletsa karabelo ea selulose ka chloroacetic acid, e lebisang ho nkeng liathomo tsa haedrojene sebakeng sa ketane ea cellulose ka lihlopha tsa carboxymethyl.Tekanyo ea substitution (DS), e bonts'ang palo e tloaelehileng ea lihlopha tsa carboxymethyl ho yuniti ea tsoekere, e susumetsa thepa ea CMC.

Thepa ea 'Mele le ea Lik'hemik'hale

1. Solubility: E 'ngoe ea likarolo tse hlahelletseng tsa CMC ke ho qhibiliha ha eona metsing, ho e etsa hore e be sesebelisoa sa bohlokoa sa ho tiisa litharollong tse nang le metsi.Tekanyo ea ho nka sebaka e ama ho qhibiliha, 'me DS e phahameng e lebisa ho ho qhibiliha ha metsi ho eketsehileng.
2. Viscosity: Carboxymethylcellulose e nkoa e le ea bohlokoa ka lebaka la bokhoni ba eona ba ho eketsa viscosity ea metsi.Sena se etsa hore e be motsoako o tloaelehileng lihlahisoa tse fapaneng, joalo ka lijo, meriana le lihlahisoa tsa tlhokomelo ea motho.
3. Thepa ea ho Etsa Lifilimi: CMC e ka etsa lifilimi ha e omme, e kenya letsoho ts'ebetsong ea eona indastering moo ho hlokehang lesela le lesesaane, le tenyetsehang.
4. Ion Exchange: CMC e na le thepa ea phapanyetsano ea ion, e e lumellang ho sebelisana le li-ion tharollong.Hangata thepa ena e sebelisoa liindastering tse kang ho cheka oli le ho hloekisa metsi a litšila.
5. Botsitso: CMC e tsitsitse tlasa maemo a fapaneng a pH, e eketsang ho feto-fetoha ha eona lits'ebetsong tse fapaneng.

Lisebelisoa

1. Indasteri ea Lijo:

• Thickening Agent: CMC e sebelisoa e le ntho e matlafatsang lihlahisoa tse fapaneng tsa lijo, ho kenyeletsoa lisoso, liaparo le lihlahisoa tsa lebese.
• Stabilizer: E tsitsisa li-emulsions lihlahisoa tsa lijo, ho thibela karohano.
• Texture Modifier: CMC e ntlafatsa sebopeho le molomo oa lijo tse itseng.

2. Meriana:

• Binder: CMC e sebelisoa e le tlama matlapeng a meriana, e thusang ho kopanya metsoako.
• Suspension Agent: E sebelisoa meriana ea metsi ho thibela ho tsitsa ha likaroloana.

3. Lihlahisoa tsa Tlhokomelo ea Motho:

• Viscosity Modifier: CMC e eketsoa ho litlolo, li-shampoo le litlolo ho fetola ponahalo ea tsona le ho ntlafatsa sebopeho sa tsona.
• Stabilizer: E tsitsisa li-emulsions ho litlolo tsa litlolo.

4. Indasteri ea Lipampiri:

• Surface Sizing Agent: CMC e sebelisoa indastering ea pampiri ho ntlafatsa thepa ea pampiri, joalo ka boreleli le khatiso.

5. Indasteri ea Masela:

• Sizing Agent: CMC e sebelisoa ho likhoele ho ntlafatsa thepa ea tsona ea ho loha le ho matlafatsa matla a lesela le hlahisoang.

6. Ho Cheka Oli:

• Moemeli oa Tahlehelo ea Mekelikeli: CMC e sebelisoa ka maro a ho cheka ho laola tahlehelo ea mokelikeli, ho fokotsa kotsi ea ho se tsitse ha seliba.

7. Phekolo ea Metsi a Litšila:

• Flocculant: CMC e sebetsa e le mokhoa oa ho kopanya likaroloana tse ntle, ho thusa ho tlosoa ha tsona mekhoeng ea ho hloekisa metsi a litšila.

Mehopolo ea Tikoloho

Carboxymethylcellulose hangata e nkuoa e bolokehile hore e ka sebelisoa lits'ebetsong tse fapaneng.E le ntho e tsoang ho cellulose, e khona ho bola, 'me phello ea eona ea tikoloho e batla e le tlase.Leha ho le joalo, ho bohlokoa ho ela hloko boemo ba tikoloho ea tlhahiso le tšebeliso ea eona.

Qetello

Carboxymethylcellulose ke polymer e feto-fetohang le ea bohlokoa e nang le lits'ebetso tse atileng liindastering tse fapaneng.Motsoako oa eona o ikhethang oa thepa, ho kenyeletsoa ho qhibiliha ha metsi, matla a ho tenya, le botsitso, e etsa hore e be karolo ea bohlokoa haholo lihlahisoa tse fapaneng.Ha liindasteri li ntse li tsoela pele ho batla litharollo tse tšoarellang le tse sebetsang hantle, karolo ea carboxymethylcellulose e kanna ea fetoha, mme lipatlisiso tse tsoelang pele li ka senola lits'ebetso tse ncha tsa polymer ena e tsotehang.
