Qhov kev tawm tsam ntawm Carboxymethyl cellulose yog tias cov khoom yuav decomposed nyob rau hauv dej, yog li qhov dispersibred nyob rau hauv cov khoom tau kuj tau los ua txoj hauv kev los txiav txim nws cov kev ua tau zoo. Cia peb kawm paub ntxiv txog nws:
1) Ib qho nqi ntawm cov dej ntxiv rau cov khoom tawg, uas tuaj yeem txhim kho qhov tsis sib xws ntawm cov dej colloidal hauv dej, thiab nws yog qhov tsim nyog los xyuas kom meej tias cov dej ntxiv tsis tuaj yeem yaj cov colloid.
2) Nws yog ib qho tsim nyog los tawg cov khoom siv colloidal hauv cov kua roj ua kua uas tsis muaj dej, tab sis nws yuav tsum loj dua qhov ntim ntawm cov khoom sib xyaw kom lawv tuaj yeem yog tag nrho cov khoom tawg Cov. Yog MonohyDric cawv xws li Methanol thiab ethanol, ethylene glycol, acetone, thiab lwm yam.
3) Cov ntsev ua kua dej-soluble yuav tsum tau ntxiv rau cov cab kuj, tab sis cov ntsev tsis tuaj yeem hnov nrog lub colloid. Nws lub ntsiab muaj nuj nqi yog los tiv thaiv cov dej-soluble gel los ntawm kev tsim cov tshuaj txhuam lossis ua daus thiab nag lossis daus thaum nws so. Feem ntau siv yog sodium chloride thiab lwm yam.
4) Nws yog ib qho tsim nyog los ntxiv cov neeg sawv cev ncua sij hawm rau cov cab kuj los tiv thaiv qhov tshwm sim ntawm gel nag lossis daus. Tus neeg sawv cev tseem ceeb tuaj yeem yog glycerin, hydroxypropylulose, thiab lwm yam. Tus neeg sawv cev ncua yuav tsum yog solubs hauv cov cab kuj ua kua thiab sib xws nrog lub colloid. Rau cov carboxymethyl cellulose, yog tias glycerol yog siv los ua qhov kev ncua tus neeg sawv cev, cov tshuaj li niaj zaus yog li 3% -10% ntawm cov cab kuj kua.
5) Thaum cov txheej txheem ntawm kev sib dhos thiab etheremation, cationic lossis cov surfactic lossis yuav tsum tau yaj nyob rau hauv cov khoom siv ua kua kom tau sib xws nrog colloids. Feem ntau siv surfactants yog Lauractants, glycerin monoeres glycol fatty acid ester, nws koob tshuaj yog li 0.05% -5% ntawm cov cab kuj kua.
