Carboxymethylcellulose (CMC) is a non-toxic and tasteless white flocculent powder with stable performance and is easily soluble in water. Its aqueous solution is a neutral or alkaline transparent viscous liquid, soluble in other water-soluble glues and resins, and insoluble in organic solvents such as ethanol.

CMC can be used as a binder, thickener, suspending agent, emulsifier, dispersant, stabilizer, sizing agent, etc.

Sodium carboxymethyl cellulose (CMC) is the product with the largest output, the widest range of uses, and the most convenient use among cellulose ethers, commonly known as "industrial monosodium glutamate".

The basic use of sodium carboxymethyl cellulose

1. For oil and natural gas drilling, well digging and other projects

① CMC-containing mud can make the well wall form a thin and firm filter cake with low permeability, reducing water loss.

② After adding CMC to the mud, the drilling rig can get a low initial shear force, so that the mud can easily release the gas wrapped in it, and at the same time, the debris can be quickly discarded in the mud pit.

③ Drilling mud, like other suspensions and dispersions, has a certain shelf life, and adding CMC can make it stable and prolong the shelf life.

④The mud containing CMC is rarely affected by mold, so it is not necessary to maintain a high pH value and use preservatives.

⑤Containing CMC as a treatment agent for drilling mud and flushing fluid, it can resist the pollution of various soluble salts.

⑥ CMC-containing mud has good stability and can reduce water loss even if the temperature is above 150°C.

CMC with high viscosity and high degree of substitution is suitable for mud with low density, and CMC with low viscosity and high degree of substitution is suitable for mud with high density. The choice of CMC should be determined according to different conditions such as mud type, region, and well depth.

2. Used in textile, printing and dyeing industry. The textile industry uses CMC as a sizing agent for light yarn sizing of cotton, silk wool, chemical fiber, blended and other strong materials;

3. Used in paper industry CMC can be used as paper smoothing agent and sizing agent in paper industry. Adding 0.1%~0.3% CMC to the pulp can increase the tensile strength of the paper by 40%~50%, increase the crack resistance by 50%, and increase the kneadability by 4~5 times. 4. CMC can be used as a dirt adsorbent when added to synthetic detergents

5. It can be used as adhesive, plasticizer, suspending agent of glaze, color fixing agent, etc. in the ceramic industry.

6. Used in construction to improve water retention and strength.
