Sodium Carboxymethyl Cellulose

Product description

Sodium Carboxymethyl Cellulose,  CMC is a typical anionic cellulose ether sodium salt, degree of substitution, that is, the average number of hydroxyl groups to react with each Anhydrous Glucose Unit Displacement, equals to 1, when its molecular formula is [ C6H7O2(OH)2OCH2COONa ] N, the structural form is usually written as:

CMC is a odorless, odourless, non-toxic white or yellowish fibrous powder. It is insoluble in high concentration organic solvents such as ethanol, ethylene glycol, propylene glycol, Acetone, etc. . When SD.S>0.4, it can be dissolved in hot and cold water and become a transparent viscous solution. Product D.S higher , the more uniform the distribution of substituents, the better the water solubility, the better the acid and salt resistance. CMC is the most widely used cellulose in the world.

3. Product Performance

(1) hygroscopicity, the degree of hygroscopicity and atmospheric temperature and relative humidity, when reached equilibrium, no longer hygroscopicity.

CMC aqueous solution has excellent properties such as adhesion, thickening, emulsification, suspension, film formation, colloid protection, water retention, anti-enzymatic hydrolysis and metabolic inertia.

when the CMC aqueous solution meets with tin, silver, aluminum, lead, iron, copper and some heavy metals, it will precipitate, but when the CMC aqueous solution coexists with calcium, magnesium and salt, it will not precipitate, but will reduce the viscosity of the CMC aqueous solution. When CMC aqueous solution encounters acid, ACIDIC CMC precipitates. But ACID-RESISTANT CMC has a certain resistance to acid solution.

Solubility: CMC aqueous solution and water-soluble Gelatin, glycerol glycol, sorbitol, Arabic

5. Packing and transportation

Packing: double-layer Bag, Outer Composite Paper Bag, inner polythene film bag, each bag net weight 25kg. Storage and transportation: Store in a dry, ventilated place indoors, pay attention to moisture-proof. Rain and Sun Protection during transportation.

6.Safety Issues

(1). The product is at risk of dust explosion. When handling in bulk or bulk, be careful to avoid dust deposition and suspension in the air, away from heat, sparks, flames, and static electricity.

(2) . Avoid Methyl cellulose, powder and contact with eyes. Wear a filter mask and safety goggles.

(3) . The product is very slippery when wet. The spilled Methyl cellulose and powder should be cleaned in time, and anti-skid treatment should be done.
