Chinese name CMC: carboxymethyl cellulose is an important cellulose ether, a water-soluble natural fibers after chemical modification of the obtained good polyanionic cellulose compounds, soluble in hot and cold water. It has emulsifying agents, solid dispersion, difficult to corrosion, unusual and valuable combination of physical and chemical properties of physiologically harmless, is a widely used natural polymer derivatives. CMC is white or yellowish powder, granular or fibrous solids, odorless, tasteless, non-toxic. CMC has a thickening, dispersing, suspending, adhesive, film, protective colloid and the protection of water and other excellent properties, widely used in food, pharmaceutical, oil, toothpaste and other industries. Main purpose: cigarette bonding, fabric sizing, footwear paste meal, home slimy. Sprayed on the interior architecture, building lines melamine, thickening mortar, concrete enhancements. Refractory fiber, ceramic production molding bonding. Oil drilling, geological exploration of the slurry thickening, reduce water loss. Quality paper surface sizing. Soap and detergent active detergent additives, and other industrial production of the dispersion, emulsification, stable, suspension, film, paper, polishing and the like. Quality product which can be used in toothpaste, medicine, food and other industrial sectors.
