In recent years, sodium carboxymethyl cellulose has developed significantly in quality, yield, variety, and technology, and its use has gradually been promoted.
It can be seen from the structural formula that the hydrogen (Na+) on CMC is easily separated in an aqueous solution (usually in the form of sodium salt). Hence, CMC exists in the form of an anion in an aqueous solution.
CMC is white or creamy white fibrous powder or granule, density 0.5-0.7g/cm3, almost odorless and tasteless, with hygroscopicity.
Sodium carboxymethyl cellulose (CMC), also known as carboxymethyl cellulose. It is a highly polymerized fiber ether prepared by chemically modifying natural cellulose. Its structure is mainly composed of D-glucose units connected by β_(14) glycosidic bonds.
Sodium carboxymethyl cellulose, referred to as carboxymethyl cellulose CMC, is a white or creamy white fibrous powder or granule with a density of 0.5-0.7g/cm3, odorless and hygroscopic. So what are the common problems when using carboxymethyl cellulose?
Carboxymethyl cellulose can form high viscosity colloid, solution, bonding, thickening, flow, emulsification, and dispersion characteristics; with water retention, protection of colloid, film-forming, acid resistance, salt resistance, suspension, and other factors, with physiological harmless and other features, widely used in food, medicine, daily chemical, petroleum, paper making, textile, construction, and other fields.
