Basic information

 

Carboxymethyl cellulose (CMC) belongs to the category of anionic cellulose ethers, with the appearance of white or slightly yellow flocculent fiber powder or white powder, odorless, odorless, and non-toxic; Easily soluble 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, ether,  etc.and soluble in ethanol solutions with 60% water content. It has hygroscopicity and is stable to light and heat. Its viscosity decreases with increasing temperature. The solution is stable at pH 2-10, and when pH is below 2, solid precipitates occur. When pH is above 10, its viscosity decreases. The color change temperature is 227 ºC, the carbonization temperature is 252 ºC, and the surface tension of the 2% aqueous solution is 71mn/n.



1,Natural cellulose is the most widely distributed and abundant polysaccharide in nature, with a very rich source.
2,The current modification technologies for cellulose mainly focus on etherification and esterification.
3,Carboxymethylation reaction is a type of etherification technology.
4,Cellulose undergoes carboxymethylation to obtain carboxymethyl cellulose (CMC).
5,Its aqueous solution has functions such as thickening, film-forming, bonding, water retention, colloid protection, emulsification, and suspension.
6,It is widely used in industries such as petroleum, food, textile, and papermaking, and is one of the most important cellulose ethers.

Carboxymethyl cellulose (CMC) is a non-toxic and odorless white flocculent powder with stable performance and easy solubility 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.



Application

 

1. Used for drilling, well digging, and other engineering projects for oil
Mud containing CMC can form thin and hard filter cakes with low permeability on the wellbore, reducing water loss.
After adding CMC to the mud, the drilling rig can achieve low initial shear force, making it easy for the mud to release the gas trapped inside, while quickly discarding debris in the mud pit.
Drilling mud, like other suspended dispersions, has a certain lifespan, and the addition of CMC can stabilize it and extend its lifespan.
Mud containing CMC is rarely affected by mold, so there is no need to maintain a high pH value or use preservatives.
Containing CMC as a drilling mud flushing fluid treatment agent, it can resist pollution from various soluble salts.Mud containing CMC has good stability and can reduce water loss even at temperatures above 150 ºC.
2. CMC is used in the textile and dyeing industries as a sizing agent for light yarn sizing of fabrics such as cotton, silk, chemical fibers, and blends.
3. CMC used in the paper industry can be used as a paper smoothing agent and sizing agent. Adding 0.1% to 0.3% CMC to the pulp can enhance the tensile strength of the paper by 40% to 50%, increase the compressive strength by 50%, and increase the knedability by 4-5 times.
4. CMC can be added to synthetic detergents as a dirt adsorbent; The glycerol aqueous solution of daily chemicals such as CMC in the toothpaste industry is used as the adhesive base for toothpaste; Used in the pharmaceutical industry as thickeners and emulsifiers; CMC aqueous solution is used for floating mineral processing after increasing viscosity.
5. Used in the ceramic industry as an adhesive, plasticizer, suspension agent for glaze, color fixing agent, etc. for making blanks.
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.
