Carboxymethyl Cellulose
Qhov tsos:dawb los yog mis nyuj dawb hmoov
Cov yam ntxwv ntawm lub cev: nws yog cellulose derivative nrog carboxymethyl pawg (-CH2-COOH) khi rau qee pawg hydroxyl ntawm glucopyranose monomers uas ua rau cov pob txha cellulose.Nws tseem hu ua CMC, Carboxymethyl.Cellulose Sodium, Sodium ntsev ntawm Caboxy Methyl Cellulose.CMC yog ib qho tseem ceeb ntawm cov dej solube polyelectrolyte.Nws tuaj yeem soluble hauv dej, insoluble hauv cawv, ethanol, benzene, chloroform thiab lwm yam organic solvents.Resistant rau tsiaj thiab zaub roj thiab tsis cuam tshuam los ntawm illumination.
