Description
Sodium carboxymethyl cellulose(9004-32-4) is a water-soluble polymer. As a solution in water, it has thixotropic properties. It is useful in helping to hold the components of pyrotechnic compositions in aqucous suspension (e.g., in the making of black match). It is also an especially effective binder that can be used in small amounts in compositions, where the binder can intcrfere with the intended effect (e.g., in strobe compositions). However, its sodium content obviously precludes its use in most color compositions. Sodium carboxymethyl-cellulose is manufactured from cellulose by various process that replace some of the hydrogen atoms in the hydroxyl[OH] groups of the cellulose molecule with acidic carboxymethyl [-CH2CO.OH] groups,which are neutralized to form the corresponding sodium salt. Sodium carboxymethyl cellulose is white when pure; industrial grade material may be grayish-white or cream granules or powder.
Function
Sodium carboxymethyl cellulose (CMC,9004-32-4) is frequently called simply carboxymethyl cellulose and also known as cellulose gum. It is derived from purified cellulose from cotton and wood pulp. It is a water dispersible sodium salt of carboxy-methyl ether of cellulose that forms a clear colloidal solution. It is a hygroscopic material that has the ability to absorb more than 50% of water at high humidity. It is also a natural polymeric derivative that can be used in detergents, food and textile industries.
CMC is one of the most important products of cellulose others, which are formed by natural cellulose modification as a kind of cellulose derivate with an ether structure. Due to the fact that the acid form of CMC has poor water solubility, it is usually preserved as sodium carboxymethylcellulose, which is widely used in many industries and regarded as monosodium glutamate in industry.
Application
CMC is used in cigarette adhesive, fabric sizing, footwear paste meal, home slimy. It is used in interior painting architectural, building lines melamine, thickening mortar, concrete enhancement. It is used in refractory fiber, ceramic production molding bond. It is used in oil drilling, exploration address slurry thickening, reducing water loss, quality paper surface sizing. It can be used as soap and washing powder detergent active additives, as well as other industrial production on the dispersion, emulsification, stability, suspension, film, paper, polishing and the like. Quality product can be used for toothpaste, medicine, food and other industrial sectors.
