الوصف

Carboxymethyl Cellulose (CMC)

MF: [C6H7O2(OH)2CH2COONa]n 
CAS No.: *****32-4 
Purity: 65%-99.5% 
Model Number: Food Grade; Industry Grade 

Appearance:White or slightly yellow powder or white powder flocculent fiber 

Physical Properties 

Sodium carboxymethyl cellulose (CMC) is an anionic cellulose ether, white or slightly yellow flocculent fiber powder or white powder, odorless, tasteless, non-toxic; Soluble in cold water or hot water to form a certain stick degree transparent solution. Solution is neutral or slightly alkaline, insoluble in ethanol, ethyl ether, isopropyl alcohol, acetone and other organic solvents, soluble in water 60% ethanol or acetone. Hygroscopic, light and heat stability, viscosity decreases with increasing temperature, pH value of the solution in the 2 to 10 stable, pH less than 2, solid precipitation, pH value is higher than 10 viscosity. Color temperature of 227 degrees, charring temperature of 252 degrees, 2% aqueous solution surface tension 71mn / n. 

Application: 

Sodium carboxymethyl cellulose (CMC) is the production of cellulose ethers in the largest, most widely used and most convenient to use the product, commonly known as "industrial monosodium glutamate. " 

A. For oil and gas drilling, wells and other projects 
1. With the CMC slurry can form a thin wall of strong, low permeability filter cake that reduces water loss. 
2. In the mud added to the CMC, can drill to get a low initial shear, so that the mud wrap easy to release the gas inside, while the debris dumped in the pit soon. 
3. Drilling mud and other suspended, like dispersion, the existence of a certain period, after adding CMC to make it stable and extend lifespan. 
4. Slurry containing CMC, with little influence by the mold, so no need to maintain high pH value, do not use preservatives. 
5. CMC-containing flushing fluid for drilling mud treatment agent can be a variety of soluble salts of anti-pollution. 
6. CMC-containing mud, good stability, even if the temperature is above 150 degrees still reduce water loss.

High viscosity, high degree of substitution of CMC for the smaller mud density, low viscosity, high degree of substitution of CMC for density slurry. CMC selection should be based mud types and regions, different conditions to determine the depth. 

B. Used in textile, industrial textile printing and dyeing industry as sizing agent to CMC for cotton, Silk, chemical fiber, blended and other strong materials veil sizing; 

C. For the paper industry in the CMC can be used in the paper industry paper smoothing agent, sizing agent. In the pulp by adding 0.1% to 0.3% of CMC can increase paper tensile 40% to 50%, 50% increase in degree of compression fracture, rubbing increased 4 to 5 times. 

D. CMC added synthetic detergentscan be used as dirt adsorbent; Daily chemical industry, such as toothpaste, glycerin aqueous solution of CMC for toothpaste gum base; Pharmaceutical industry as a thickener and emulsifier; CMC aqueous tackifier for use as floating dressing and so on. 

E. For the ceramics industry to do the rough adhesives, plasticizers, glaze suspension, fixing agent. 

F. Used in construction, improve water retention and strength 

G. For the food industry, food industry with high degree of CMC replacement for ice cream, canned food, fast cooking of the thickener, beer foam stabilizer in the processing of jam, syrup, sherbet, dessert, ice cream, drinks, etc. Do as thickener, adhesive agent or by shape. 

H. The pharmaceutical industry the choice of appropriate viscosity CMC as tablet binders, disintegrating agents, suspension of a suspending agent.
