Influencing Factors ntawm Sodium carboxymethylcellulose Viscosity

Sodium carboxymethylcellulose (NaCMC) viscosity tuaj yeem cuam tshuam los ntawm ntau yam, suav nrog:

1. Concentration: NaCMC viscosity nce nrog nce concentration. Qhov no yog vim ntau dua ntawm NaCMC ua rau muaj ntau dua molecular entanglement, uas ua rau kom muaj viscosity.
2. Molecular Luj: NaCMC nrog qhov hnyav dua molecular feem ntau muaj viscosity ntau dua li qhov hnyav molecular NaCMC. Qhov no yog vim qhov hnyav dua molecular NaCMC muaj cov hlua ntev dua, ua rau muaj ntau dua molecular entanglement thiab nce viscosity.
3. Kub: NaCMC viscosity feem ntau txo qis nrog nce kub. Qhov no yog vim tias qhov kub siab dua ua rau cov saw hlau polymer ua ntau lub xov tooj ntawm tes, ua rau txo qis viscosity.
4. pH: NaCMC feem ntau viscous ntawm pH ntawm ib ncig ntawm 7. siab dua lossis qis dua pH qhov tseem ceeb tuaj yeem ua rau cov viscosity poob vim muaj kev hloov pauv hauv ionization thiab solubility ntawm NaCMC molecules.
5. Ntsev concentration: Lub xub ntiag ntawm ntsev tuaj yeem cuam tshuamNaCMC viscosity, nrog cov ntsev ntau dua feem ntau ua rau txo viscosity. Qhov no yog vim tias cov ntsev tuaj yeem cuam tshuam nrog kev cuam tshuam ntawm NaCMC chains, ua rau txo qis molecular entanglement thiab viscosity.
6. Shear rate: NaCMC viscosity kuj tuaj yeem cuam tshuam los ntawm tus nqi ntawm shear lossis ntws. Ntau dua shear tus nqi tuaj yeem ua rau txo viscosity vim qhov tawg ntawm molecular entanglements ntawm NaCMC chains.

Kev nkag siab txog cov xwm txheej no thiab seb lawv cuam tshuam li cas ntawm NaCMC viscosity yog qhov tseem ceeb rau kev ua kom zoo dua nws siv hauv ntau daim ntawv thov, xws li hauv cov khoom noj, tshuaj, thiab cov khoom tu tus kheej.
