Lub cev muaj zog ntawm Carboxymethyl Cellulose

Carboxymethyl cellulose (CMC) yog ib qho anionic cellulose ether, uas yog dawb los yog yellowish flocculent fiber hmoov los yog hmoov dawb nyob rau hauv tsos, tsw, saj thiab tsis muaj tshuaj lom; Nws yog yooj yim soluble nyob rau hauv dej txias los yog dej 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 nyob rau hauv ethanol, ether, isopropanol, acetone thiab lwm yam organic solvents, thiab soluble nyob rau hauv ethanol los yog acetone tov uas muaj 60 feem pua ​​dej. Nws muaj hygroscopicity thiab ruaj khov rau lub teeb thiab kub. Nws viscosity txo nrog qhov nce ntawm qhov kub thiab txias. Cov tshuaj yog ruaj khov ntawm pH 2 ~ 10. Thaum pH qis dua 2, muaj cov kua dej khov. Thaum pH siab tshaj 10, nws viscosity txo. Qhov kub discoloration yog 227 degree, carbonization kub yog 252 degree, thiab qhov nro ntawm 2 feem pua ​​aqueous tov yog 71 mn / n.
