CMC Sodium Carboxymethyl Cellulose

CMC Sodium Carboxymethyl Cellulose

Carboxymethylcellulose (CMC) is an anionic, linear, water-soluble cellulose ether. Its aqueous solution has the functions of thickening, film-forming, adhesion, moisture retention, colloid protection, emulsification and suspension. As flocculants, emulsifiers, thickeners, water retaining agents, sizing agents, film-forming materials, etc., it is widely used in food, electronics, pesticides, leather, plastics, printing, ceramics, daily chemicals and other fields.

CMC  Application

1. Architectural decoration applications: spraying lime slurry, mixing gypsum putty, mixing cement putty, paint spraying, roller coating, brushing, art decoration, plastering, pasting wallpaper, wall coverings, floor tiles, ceramic tiles, ceramic mosaic tiles wait.

2. Application in synthetic detergent and soap industry: CMC is the best active additive for synthetic detergents. It is mainly used in detergents to utilize its emulsifying and protective colloid properties, which can prevent dirt from being deposited on the washed items, keep white fabrics white, and make colored fabrics bright-colored.
Other advantages of CMC for synthetic detergents are:
It has a washing aid effect, especially when washing cotton fabrics in hard water. It can stabilize foam, not only save washing time but also allow repeated use of washing liquid; the fabric will feel soft after washing; and reduce irritation to the skin.
After CMC is used in slurry detergent, in addition to the above effects, it also has a stabilizing effect to prevent the detergent from settling. Adding an appropriate amount of CMC when making soap can improve the quality. In addition to the same mechanism and advantages as the above-mentioned synthetic detergents, it can also make the soap material soft and easy to process and press, and the extruded soap bars are smooth and beautiful.
CMC has a post-milk effect that can make spices and dyes evenly distributed in soap, so it is especially suitable for soap.

3. Application of mud in oil drilling and other engineering projects: In drilling and oil drilling engineering, good mud must be prepared to ensure the normal operation of the drilling. Good mud must have appropriate specific gravity, viscosity, thixotropy, water loss and other values. These values have their own requirements depending on the region, well depth, mud type and other conditions. Using CMC in the mud can adjust these physical parameters, such as reducing loss. Water volume, adjust viscosity, increase thixotropy, etc.

Mud containing CMC can make the well wall thin and strong, with low permeability, thereby reducing the water loss rate and reducing shrinkage, collapse and other phenomena caused by the water loss of the mud penetrating into the formation. Mud containing CMC is rarely affected by mold, so there is no need to maintain a high pH or use preservatives, and accordingly reduce the amount of other chemicals.

When using, CMC should be dissolved in water to form a solution and added to the mud. CMC can also be added to the mud together with other chemicals.

4. Application in textile printing and dyeing industry. In recent years, the textile industry has widely used CMC as a sizing agent instead of starch. Practice has proved that CMC sizing not only saves a lot of food and oil, but is also much superior to using starch, animal glue, etc. Using CMC as a binder on cotton, silk, wool, chemical fibers, synthetic fibers or blended fabrics and warp yarns has the following advantages: the CMC aqueous solution is clear, transparent, uniform, and has good stability. There is no change when pumped or stirred. Production requires ready access. The CMC aqueous solution is rich in viscosity and film-forming properties. It can form a smooth, wear-resistant and flexible film on the surface of the warp yarn, which can withstand the sheer force of the loom and provides favorable conditions for high-speed production. The yarn treated with CMC aqueous solution is easy to dry, shiny and soft to the touch.

Printing paste CMC is used as a thickener and emulsifier in printing paste. Especially suitable for silk printing color paste. Printing pastes for man-made fabrics such as acetate should contain high boiling point solvents, dyes, water and sufficient thickeners. CMC is both a thickener and an emulsifier. Adding CMC to printing paste has the following advantages:

(1) Significantly improve the vividness of printing. Because the color matching of general slurries is based on water, CMC has strong hygroscopicity, so it can increase the color matching rate and improve the brightness.

(2) Good permeability. The permeability of CMC slurry is better than that of starch slurry. Especially for fabrics that require deep and transparent fabrics such as georgette velvet, it not only produces a deep and transparent color, but also reduces labor intensity.

(3) Easy to desizing and soft texture.

(4) Improve the stability of color paste. CMC is not prone to mold and deterioration, so the color paste is more stable than starch.

(5) Strong adhesion. In manual printing, most nylon fabrics are very thin, and it is difficult to make them stick to the flat plate with ordinary adhesives. Therefore, they often dome and are difficult to print. With CMC, they can lie flat and stick to the flat plate, which is good. Convenient for operation.

5. Application in the papermaking industry: CMC has film-forming properties and can be used as a paper smoothing agent and sizing agent in the papermaking industry. Adding 0.1-0.3% CMC to the pulp can increase the paper tension by 40-50% and increase the tension of the paper by 40-50%. The kneadability is 4-5 times, and the paper quality is uniform, the ink easily penetrates during printing, and the edges of the printed matter are clear.

6. Application in ceramic industry: CMC has good adhesion and film formation properties. It can enhance the bonding force between glaze and ceramics to prevent the glaze from falling off, and promote the diffusion of glaze. CMC can be used as a binder for sintering molding and as a fixing agent for ceramics.

7. Used in the food industry: CMC is odorless, tasteless, non-toxic, can be stored for a long time without spoilage, has high viscosity, strong shape retention, is easy to dissolve, and can be used in food processing. Such as viscosity agent, thickener, stabilizer, solid agent, film forming agent, etc.

8. Used in the coating industry: CMC can be used as water-soluble coatings, and can be used for gluing or adjusting viscosity. In paint printing, it acts as an emulsifier and stabilizer.
