Cov Khoom Siv Ntawm Sodium Carboxymethyl Cellulose

Sodium Carboxymethyl cellulose yog anionic cellulent fibrous hmoov lossis xim daj me ntsis hauv tsos, tsw qab, tsis muaj tshuaj lom; Cov dej yooj yim hauv cov dej txias lossis dej kub kom tsim cov tshuaj ntsuab nrog qee yam kev daws teeb meem, kev daws teeb meem yog nruab nrab lossis me ntsis alkaline; Insoluble hauv cov kuab tshuaj muaj zog xws li ethanol, ethanol, acetone, thiab lwm yam hauv 60% dej-muaj ethanol lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone tov lossis acetone daws.

Nws yog hygroscopic, ruaj khov rau lub teeb thiab kub, qhov kev daws teeb meem yog qhov qis dua 2-10, muaj cov khoom siv nag tsawg dua, thiab tus nqi PH yog siab dua 10, lub viscosity txo. Qhov kub thiab txias yog 227 ℃, cov pa hluav taws kub yog 252 ℃, thiab cov tshuaj muaj ntau ntawm 21mn / n.

Nov yog cov cuab yeej ntawm lub cev ntawm sodium carboxymethyl cellulose, yuav ua li cas ruaj khov yog nws?

Lub cev nqaij daim tawv ntawm cov sodium carboxymethyl cellulose yog ruaj khov, yog li nws nthuav dav ntev ntev lossis hmoov ntev. Nws tsis muaj kob, ntxhiab tsw thiab tsis muaj tshuaj lom tau tuaj yeem siv tau ntau zaus, xws li kev lag luam khoom noj khoom haus, kev lag luam tshuaj, thiab lwm yam; Nyob rau tib lub sijhawm, nws muaj solubility zoo heev thiab yuav yaj nyob rau hauv cov dej txias los yog tsis muaj zog alkaline, yog li nws tuaj yeem siv ntau cov ntawv thov thiab coj cov teebmeem zoo.

Nws yog precisely vim sodium carboxymethyl cellulose yog soluble heev uas nws tuaj yeem siv tau ntau nyob rau hauv kev tsim khoom thiab lub neej. Ntawm chav kawm, nws lub cev muaj zog yog ruaj khov, thiab cov txiaj ntsig nws tuaj yeem coj tau pom tseeb, cia peb nyiam sib txawv.
