Film forming zog:
CMS tuaj yeem tsim cov yeeb yaj kiab tsis tu ncua thiab txuas ntxiv ntawm qhov chaw ntawm qhov khoom nrog adhesion zoo thiab tuav dej.
Qhov no ua rau CMS dav siv hauv zaub mov, tshuaj pleev ib ce, ntawv txheej thiab lwm yam.
pH stability:
CMS tuaj yeem tswj hwm kev ua haujlwm ruaj khov nyob rau hauv qhov dav pH ntau (pH 5-10) thiab tsis muaj hydrolysis lossis degradation.
Thermal stability:
CMS tseem tuaj yeem tswj hwm kev ruaj ntseg zoo nyob rau hauv cov cua sov thiab tsis ua rau thermal decomposition lossis discoloration.
Qhov no tso cai rau CMS tswj nws cov thickening thiab stabilizing cov teebmeem thaum ua haujlwm kub.
Zoo compatibility:
CMS muaj kev sib raug zoo nrog ntau yam tshuaj thiab tuaj yeem sib xyaw nrog lwm cov tshuaj ntxiv, pigments, thiab lwm yam kom tau raws li qhov xav tau ntawm cov khoom sib txawv.
Qhov tsos:feem ntau yog cov hmoov dawb los yog dawb dawb
Solubility:Yooj yim soluble hauv dej, tsim cov kua dej khov
Kev ruaj ntseg:Nyob ruaj khov nyob rau hauv qhuav tej yam kev mob, tab sis tej zaum yuav decompose nyob rau hauv siab kub los yog muaj zog acid thiab alkali tej yam kev mob
Chemical Properties:
Carboxymethylation:Cov pawg hydroxyl nyob rau hauv cov hmoov txhuv nplej siab yog hloov los ntawm carboxymethyl pawg, yog li ua rau nws cov hydrophilicity thiab viscosity.
Degree ntawm kev hloov:Qib ntawm carboxymethyl hloov pauv txiav txim siab qhov ua tau zoo thiab siv cov khoom
Txoj kev tsim khoom:
Cov hmoov txhuv nplej siab tau npaj los ntawm kev ua haujlwm nrog carboxymethylating reagents (xws li chloroacetic acid) nyob rau hauv cov kab mob alkaline, ua raws li cov kauj ruam xws li neutralization, ntxuav, thiab ziab.
