1、 CMC Introduction:

Full English name: Carboxyl methyl Cellulose. The current modification technology of cellulose mainly focuses on etherification and esterification. Carboxymethylation reaction is a type of etherification technology. Carboxymethyl cellulose (CMC) is obtained by carboxymethylation of cellulose. Its aqueous solution has functions such as thickening, film-forming, bonding, moisture retention, colloid protection, emulsification, and suspension. It is widely used in industries such as petroleum, food, medicine, textile, and paper, and is one of the important cellulose ethers.

2、 CMC properties:

Carboxymethyl cellulose sodium (CMC) belongs to the anionic cellulose ether class, appearing as white or slightly yellow flocculent fiber powder or white powder, odorless, tasteless, non-toxic; Easy to dissolve in cold or hot water, forming a transparent solution with a certain viscosity. The solution is neutral or slightly alkaline, insoluble in organic solvents such as ethanol, isopropanol, acetone, etc., and soluble in ethanol or acetone solutions containing 60% water. It has hygroscopicity, is stable to light and heat, and its viscosity decreases with increasing temperature. The solution is stable at pH 2-10, and solid precipitation occurs when pH is below 2. Its viscosity decreases when pH is above 10. The color changing temperature is 227 ℃, the carbonization temperature is 252 ℃, and the surface tension of a 2% aqueous solution is 71mn/n.

3、 Main uses of CMC:

Carboxymethyl cellulose (CMC) is a non-toxic and odorless white flocculent powder with stable properties, easily soluble in water. Its aqueous solution is a neutral or alkaline transparent viscous liquid, soluble in other water-soluble adhesives and resins, and insoluble in organic solvents such as ethanol. CMC can be used as an adhesive, thickener, suspension agent, emulsifier, dispersant, stabilizer, sizing agent, etc.

Carboxymethyl cellulose sodium (CMC) is a widely produced, versatile, and convenient product among cellulose ethers, commonly known as "industrial monosodium glutamate".

1. Used for drilling, digging and other engineering projects related to oil and natural gas.

2. CMC is used as a sizing agent in the textile and printing and dyeing industries, for sizing light yarns of strong fabrics such as cotton, silk, chemical fibers, and blends;

3. CMC can be used as a paper smoothing agent and sizing agent in the papermaking industry. Adding 0.1% to 0.3% CMC to pulp can enhance the paper's tensile strength by 40% to 50%, increase its compressive strength by 50%, and increase its workability by 4 to 5 times.

4. CMC can be added to synthetic detergents as a dirt adsorbent; The glycerol aqueous solution of CMC in daily chemical products such as toothpaste industry is used as the base for toothpaste; Used in the pharmaceutical industry as thickeners and emulsifiers; CMC aqueous solution is used for flotation beneficiation after thickening.

5. Used in the ceramic industry as a raw material for adhesives, plasticizers, suspension agents for glazes, fixing agents, etc.

6. Used in construction to improve water retention and strength

7. It is used in the food industry. In the food industry, CMC with high displacement degree is used as the thickener of ice cream, cans, instant noodles, foam stabilizer of beer, etc., and it is used as the thickener, binder or shaping agent in the processing of jam, syrup, fruit juice, Dim sum, ice cream drinks, etc.

8. The pharmaceutical industry uses CMC with appropriate viscosity as an adhesive, disintegrant, and suspension aid for tablets.
