Sodium Carboxymethyl Cellulose (CMC)
Daim ntawv thov
Muaj ntau qhov kev txwv uas txhais cov khoom ntawm Sodium Carboxymethyl Cellulose CMC.
√ Purity (active CMC cov ntsiab lus):inevitably CMC hmoov yog tsim los ntawm cov khoom uas yog sodium ntsev uas tuaj nyob rau hauv cov khoom Sodium Carboxymethyl Cellulose cov ntsiab lus nyob rau hauv cov khoom yog purity.
√ Viscosity:ib qho ntawm cov yam ntxwv ntxim nyiam tshaj plaws ntawm CMC hmoov yog cov viscosity uas tuaj yeem yog los ntawm qis mus rau siab. Nws yog ntsuas feem ntau los ntawm cov viscometers ntawm qee qhov kub hauv cov nqi sib txawv; xws li 1%, 2% lossis 4%.
√ Degree ntawm Hloov:yog tus naj npawb nruab nrab ntawm sodium carboxymethyl pawg ib chav tsev anhydroglucose ntawm cellulose rov qab pob txha. Qhov kev ntsuas no hauv qee qhov chaw thov yog qhov tseem ceeb heev rau kev tswj hwm hauv cov khoom.
√ Lub cev daim ntawv:CMC hmoov tuaj yeem tsim cov hmoov zoo rau cov hmoov tsis muaj hmoov av.

Muaj nuj nqi
Ua tsaug rau nws txoj kev ua tau zoo, CMC tuaj yeem muab cov haujlwm sib txawv thiab qhov ntawd yog qhov nws tshuav rau siv rau hauv ntau qhov kev lag luam.
√ Solubility
√ Rheology
√ Adsorption ntawm qhov chaw
Cov yam ntxwv tseem ceeb no pab peb CMC muab kev tswj xyuas cov khoom ntawm lub tshuab aqueous los ntawm kev tsim cov teebmeem ntawm
√ Thickening
√ Kev khi
√ Kev ua yeeb yaj kiab
√ Stabilizing
√ Tiv thaiv colloid
√ Kev tuav dej
√ Thixotropy
