Product Name: sodium carboxymethyl cellulose(CMC)
The appearance of carboxymethyl cellulose CMC is white or light yellow flocculent fiber powder or white powder, odorless, tasteless, non-toxic; easily soluble in cold water or hot water, forming a gel, the solution is neutral or slightly alkaline, It is insoluble in organic solvents such as ethanol, ether, isopropanol, and acetone, but soluble in ethanol or acetone solution containing 60% water. It is hygroscopic, stable to light and heat, and the viscosity decreases with the increase of temperature. The solution is stable at PH value of 2-10, and the pH value is lower than 2, and solids are precipitated, and the viscosity is lowered when the PH value is higher than 10. The discoloration temperature is 227℃, the carbonization temperature is 252℃, and the surface tension of 2% aqueous solution is 71mn/n.
|Viscosity,2% water solution||500-600||800-1000||1500-2000|
|Loss on drying||≤10%|
Sodium Carboxymethyl Cellulose (CMC) is a product of cellulose ethers with large output, wide application and convenient use, commonly known as "industrial monosodium glutamate".
The important characteristics of CMC are the formation of high-viscosity colloids, solutions, adhesion, thickening, flow, emulsification and dispersion, shaping, water retention, protective colloids, film forming, acid resistance, salt resistance, suspension and other characteristics, and physiologically harmless. Therefore, it is widely used in the production of food, medicine, daily chemical, petroleum, papermaking, textile, construction and other fields.
