viscosity:
Viscosity yog qhov tseem ceeb ntawm kev tswj hwm tus cwj pwm rheological thiab kev ua haujlwm ntawm NaCMC cov kev daws teeb meem.
Thaum siv, yam xws li shear rate, kub, thiab kev laus tuaj yeem hloov viscosity ntawm NaCMC cov kev daws teeb meem, cuam tshuam rau nws cov thickening thiab stabilizing zog hauv daim ntawv thov xws li zaub mov thiab tshuaj formulations.

Molecular Luj:
NaCMC tuaj yeem raug degradation thaum siv, ua rau txo qhov hnyav molecular.
Qhov kev txo qis hauv molecular no tuaj yeem cuam tshuam ntau yam khoom, suav nrog viscosity, solubility, thiab muaj peev xwm tsim cov yeeb yaj kiab, yog li cuam tshuam rau tag nrho cov kev ua tau zoo ntawm NaCMC-raws li cov khoom.

3.Chemical Hloov:

Kev sib txuas:
Kev sib txuas ntawm NaCMC molecules tuaj yeem tshwm sim thaum siv, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov cuam tshuam nrog cov cations sib txawv lossis cov neeg ua haujlwm sib txuas.
Kev sib txuas sib txuas hloov pauv cov qauv hauv lub network polymer, cuam tshuam cov khoom xws li solubility, viscosity, thiab gelation cwj pwm, yog li cuam tshuam rau kev ua haujlwm ntawm NaCMC hauv ntau daim ntawv thov.

Kev Hloov Kho Cov Qauv:
Kev hloov kho tshuaj, xws li carboxymethylation degree thiab hloov cov qauv, tuaj yeem hloov pauv thaum siv, cuam tshuam rau tag nrho cov qauv thiab cov khoom ntawm NaCMC.
Cov qauv kev hloov pauv cuam tshuam rau cov khoom xws li dej tuav, kev sib khi, thiab kev sib khi, yog li cuam tshuam rau kev ua haujlwm ntawm NaCMC hauv kev siv xws li cov khoom noj khoom haus thiab cov tshuaj formulations.

4.Ib feem ntawm daim ntawv thov:

Kev lag luam zaub mov:
Kev hloov pauv ntawm lub cev thiab tshuaj lom neeg ntawm NaCMC thaum siv tuaj yeem cuam tshuam nws txoj haujlwm ua cov thickener, stabilizer, lossis emulsifier hauv ntau yam khoom noj.
Kev nkag siab txog cov kev hloov pauv no yog qhov tseem ceeb rau kev tswj xyuas cov khoom zoo thiab sib xws hauv cov khoom noj.

Pharmaceutical Industry:
NaCMC yog dav siv nyob rau hauv cov tshuaj formulations rau nws binder, disintegrant, thiab viscosity-hloov zog.
Kev hloov pauv hauv lub cev thiab tshuaj lom neeg ntawm NaCMC thaum siv tuaj yeem cuam tshuam nws qhov kev ua tau zoo hauv cov tshuab xa tshuaj, tswj cov qauv tsim tawm, thiab cov ntawv thov tshuaj.

5. Textile Kev Lag Luam:

NaCMC yog siv rau hauv kev lag luam textile rau sizing, luam ntawv, thiab tiav daim ntawv thov.
Kev hloov pauv hauv cov khoom xws li viscosity thiab molecular hnyav thaum siv tuaj yeem cuam tshuam rau kev ua haujlwm ntawm NaCMC-based sizing agents lossis luam ntawv pastes, yuav tsum tau hloov kho hauv kev tsim thiab kev ua haujlwm.

Sodium carboxymethyl cellulose (NaCMC) tau hloov pauv lub cev thiab tshuaj lom neeg tseem ceeb thaum siv, cuam tshuam rau nws cov solubility, viscosity, molecular hnyav, thiab cov yam ntxwv ntawm cov khoom. Cov kev hloov pauv no muaj kev cuam tshuam loj heev rau kev ua haujlwm thiab kev ua haujlwm ntawm NaCMC-raws li cov khoom lag luam thoob plaws ntau yam kev lag luam, suav nrog zaub mov, tshuaj, thiab textiles. Kev nkag siab txog cov kev hloov pauv no yog qhov tseem ceeb rau kev ua kom zoo tshaj plaws ntawm kev tsim, kev ua, thiab kev siv ntawm NaCMC, yog li ua kom muaj kev ua tau zoo thiab zoo ntawm cov khoom kawg. Kev tshawb fawb ntxiv tau lees paub los tshawb nrhiav cov tswv yim los txo cov kev hloov pauv uas tsis xav tau thiab txhim kho kev ua tau zoo ntawm NaCMC hauv ntau daim ntawv thov.
