Sodium Carboxymethyl Cellulose

Main use

Carboxymethyl cellulose (CMC) as a white flocculent powder, non-toxic tasteless, stable performance, easy to dissolve in water, its water solution is neutral or alkaline transparent viscous liquid, soluble in water soluble glue and resin, not soluble in organic solvents such as ethanol. CMC can be used as binder, thickener, suspending agent, emulsifier, dispersant, stabilizer, sizing agent and so on.

Sodium carboxymethyl cellulose (CMC) is a kind of cellulose ether in the production of large, widely used, the use of ultra convenience products, commonly known as "industrial monosodium glutamate".

1, for oil and gas drilling, digging well engineering

The mud containing CMC can make the shaft wall form a thin and strong filter cake with low permeability.

The CMC is added into the mud, can make the rig get low initial strength, the mud is easy to discharge air in it at the same time, the debris soon abandoned in the mud.

Drilling mud, as well as other suspensions, has a certain period of existence, which can stabilize and prolong the existence period of CMC.

The CMC containing mud, little affected by mold effect, therefore, the requirement to maintain a high pH value, also need not use preservatives.

The CMC containing liquid treating agent of drilling mud flushing, anti pollution caused by various soluble salts.

The CMC containing mud, good stability, even if the temperature is above 150 DEG C can reduce water loss.

High viscosity, high degree of substitution of CMC for small density of mud, low viscosity and high degree of substitution of CMC for large density of mud. CMC should be selected according to the type and area of mud, well depth and other conditions.

2, for the textile printing and dyeing industry, the textile industry will be CMC as sizing agent for cotton, wool, silk, chemical fiber, blended fabric sizing gauze;

3, used in the paper industry CMC in the paper industry can be used as paper smoothing agent, sizing agent. The addition of 0.1% to CMC of paper in the pulp can make the tensile strength of the paper increased from about 40% to 50%, and the compressive fracture degree increases by 50%, and the rubbing property increases by a factor of 4 to 5 times.

4, CMC added as dirt adsorbent in synthetic detergent; daily chemical such as glycerin water solution CMC toothpaste industry is used as a gum base toothpaste; pharmaceutical industry as a thickener and emulsifier; CMC aqueous solution viscosity for flotation etc..

5, for the ceramic industry can be used as blank adhesive, plasticizer, glaze suspending agent, fixing agent etc..

6, used in construction, improve water retention and strength

7, for the food industry, the food industry with high substitution degree CMC for ice cream, canned food, fast cooking thickener, beer foam stabilizer, in the processing of jam, syrup, fruit, snacks, drinks and ice cream as a thickener, binder or because of the shape of the agent.

8, the pharmaceutical industry with proper viscosity CMC as tablet binder, disintegrant, suspension of suspending agent.

Carboxymethyl cellulose (CMC) of high-end products for the replacement of polyanionic cellulose ((PAC) is a kind of anionic cellulose ether, has a higher degree of substitution and replace the uniformity of the molecular chain is shorter, more stable molecular structure, so it has better resistance to salt, acid, calcium, high temperature resistance also, the solubility enhancement. Applied to carboxymethyl cellulose (CMC) can be applied in all industries, can provide better stability and meet the higher requirements of the process.
