Sodium carboxymethyl celluloseyog ib qho anionic cellulose ether nrog dawb los yog daj me ntsis flocculent fibrous hmoov los yog hmoov dawb nyob rau hauv tsos, tsw tsw, saj thiab tsis muaj tshuaj lom; yooj yim soluble nyob rau hauv dej txias los yog kub los tsim ib tug pob tshab tov nrog ib tug tej yam viscosity, cov tshuaj yog nruab nrab los yog me ntsis alkaline; Insoluble hauv cov kuab tshuaj organic xws li ethanol, ether, isopropanol, acetone, thiab lwm yam, soluble hauv 60% dej-muaj ethanol lossis acetone kua.
Nws yog hygroscopic, ruaj khov rau lub teeb thiab cua sov, viscosity txo nrog qhov nce ntawm qhov kub thiab txias, kev daws teeb meem ruaj khov ntawm PH tus nqi ntawm 2-10, PH tus nqi qis dua 2, muaj dej nag, thiab PH tus nqi siab dua 10, viscosity txo. Qhov kub discoloration yog 227 ℃, carbonization kub yog 252 ℃, thiab qhov nro ntawm 2% aqueous tov yog 71mn / n.
Qhov no yog lub cev khoom ntawm sodium carboxymethyl cellulose, nws ruaj khov li cas?
Lub cev muaj zog ntawm sodium carboxymethyl cellulose yog qhov ruaj khov, yog li nws nthuav tawm cov hmoov dawb los yog daj hmoov ntev ntev. Nws cov khoom tsis muaj xim, tsis muaj ntxhiab thiab tsis muaj tshuaj lom tuaj yeem siv rau ntau lub sijhawm, xws li kev lag luam khoom noj, tshuaj lom neeg kev lag luam, thiab lwm yam; Nyob rau tib lub sijhawm, nws muaj cov solubility zoo heev thiab tuaj yeem yaj hauv dej txias lossis dej kub los tsim cov gel, thiab cov kua dej yaj yog nruab nrab lossis tsis muaj zog alkaline, yog li nws tuaj yeem siv ntau yam kev siv thiab ua rau muaj txiaj ntsig zoo dua.
Nws yog qhov tseeb vim tias sodium carboxymethyl cellulose yog soluble heev uas nws tuaj yeem siv tau ntau zaus hauv kev tsim khoom thiab lub neej. Tau kawg, nws lub cev lub cev muaj zog heev, thiab cov txiaj ntsig nws tuaj yeem nqa tau yuav pom tseeb heev, ua rau peb txaus siab rau qhov sib txawv.
