Product Description

CMC L Technical-Grade Low-Viscosity Sodium Carboxymethyl Cellulose Filtration Control Drilling Fluid AdditiveNatural cellulose is the most widely distributed and abundant polysaccharide in nature, and its sources are very rich. Current cellulose modification technology mainly focuses on etherification and esterification. Carboxymethylation reaction is a type of etherification technology. Carboxymethyl cellulose (CMC) is obtained after carboxymethylation of cellulose. Its aqueous solution has the functions of thickening, film-forming, adhesion, moisture retention, colloid protection, emulsification and suspension. It is widely used in petroleum, food, medicine and so on. , textile and paper making industries, it is one of the most important cellulose ethers.

Carboxymethyl cellulose (CMC) is a non-toxic and odorless white flocculent powder with stable performance and easily soluble in water. Its aqueous solution is a neutral or alkaline transparent viscous liquid, soluble in other water-soluble glues and resins, but insoluble In organic solvents such as ethanol. CMC can be used as a binder, thickener, suspending agent, emulsifier, dispersant, stabilizer, sizing agent, etc.
Carboxymethyl cellulose (CMC) is the product with the largest production volume, the most wide range of uses, and the most convenient use among cellulose ethers. It is commonly known as "industrial MSG".
1. Used in oil and natural gas drilling, well digging and other projects
a. CMC-containing mud can form a thin, hard, low-permeability filter cake on the well wall, reducing water loss.
b. After adding CMC to the mud, the drilling rig can obtain a low initial shear force, making it easy for the mud to release the gas trapped in it, and at the same time, the debris will be quickly discarded in the mud pit.
c. Drilling mud, like other suspended dispersions, has a certain existence period. Adding CMC can stabilize it and extend its existence period.
d. Mud containing CMC is rarely affected by mold, so there is no need to maintain a high pH value or use preservatives.
e. Containing CMC as drilling mud cleaning fluid treatment agent, which can resist the pollution of various soluble salts.
f. 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, while CMC with low viscosity and high degree of substitution is suitable for mud with high density. The selection of CMC should be determined based on different conditions such as mud type, region, and well depth.
2. Used in the 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 fabrics;
3. Used in the papermaking industry. CMC can be used as paper smoothing agent and sizing agent in the papermaking industry. Adding 0.1% to 0.3% CMC to paper pulp can increase the paper's tensile strength by 40% to 50%, increase its compressive strength by 50%, and increase its kneadability by 4 to 5 times.
4. CMC can be used as a dirt adsorbent when added to synthetic detergents; in daily chemicals such as the toothpaste industry, the glycerin aqueous solution of CMC is used as the gum base of toothpaste; in the pharmaceutical industry, it is used as a thickener and emulsifier; after the CMC aqueous solution is thickened, it is used as a float Mineral processing, etc.
5. Used in the ceramic industry as an adhesive, plasticizer, glaze suspending agent, and color-fixing agent for blanks.
6. Used in construction to improve water retention and strength.
7. Used in the food industry. The food industry uses CMC with a high degree of substitution as a thickener for ice cream, canned food, instant noodles, and a foam stabilizer for beer. It is used in the processing of jam, syrup, sherbet, snacks, ice cream drinks, etc. As a thickening agent, binder or shaping agent.
8. The pharmaceutical industry selects CMC with appropriate viscosity as binder, disintegrant for tablets, and suspending agent for suspensions.
