Introduction to the application fields of carboxymethyl cellulose (CMC)

Shijiazhuang Qingquan Cellulose Co., Ltd.'s carboxymethyl cellulose (CMC) has a wide range of applications. It is commonly used as a hydrogel, thickener, suspending agent, film-forming agent, emulsifying stabilizer, sizing agent, coating agent, adhesive, and protective colloid, among others.

1. Detergents: Carboxymethyl cellulose (CMC) is a basic component of powdered detergents, especially phosphate-free powders.  Its colloidal properties prevent dust from contaminating textile fibers, a common problem when using synthetic detergents. It stabilizes foam and protects hands. CMC can be added to non-ionic liquid detergents to prevent textile fibers from re-absorbing dust. CMC can also be used as a thickener, stabilizer, binder, and plasticizer in soaps and laundry powders.

2. Wallpaper Paste: Carboxymethyl cellulose (CMC) is ideal for wallpaper paste. This paste is easy to prepare and use, and it does not easily stain or discolor wallpaper. It provides excellent results. When used in printing wallpaper, CMC is a good pigment binder.

3. Coatings: Carboxymethyl cellulose (CMC) is a good binder for fillers and plaster, and can be used to thicken and stabilize latex paints.

4. Paper Industry: Used as a sizing agent in the paper industry.

5. Building Materials: Due to the plasticizing properties of carboxymethyl cellulose (CMC), it is commonly used in traditional plaster materials to slow down the hardening process, thus extending the working time of the plaster after mixing.

6. Textiles: Carboxymethyl cellulose (CMC) can be applied to gauze, providing protection during the weaving process, maintaining good elasticity, and improving smoothness. CMC is also a good finishing agent, compatible with most standard products. It improves the feel of the fibers and maintains their natural vibrant colors.

7. Ceramics: Carboxymethyl cellulose (CMC) is used as a binder and thickener for glazes, and also as a binder and plasticizer for ceramic clay bodies.

8. Cosmetics: CMC is used as a thickener in toothpaste, and also in skin creams, shampoos, bath gels, and conditioners. 8. Electrodes: CMC specifically designed for electrode applications is added to the coated electrode compound during extrusion, acting as a binder, plasticizer, and finishing agent. 9. Drilling: Carboxymethyl cellulose (CMC) can be used as a basic additive in drilling mud, acting as a protective colloid and viscosity modifier, and reducing filtrate loss.  Specialized grades can also be developed to adapt the drilling rig to the characteristics of the mud. Carboxymethyl cellulose (CMC) is used in oil and gas drilling, water well drilling, boreholes, core drilling, horizontal drilling, and mining. It has high water loss control capabilities. CMC is also a highly effective fluid loss reducer; at low concentrations, it can control water loss to a high level without affecting other properties of the drilling mud. The resulting mud cake is of good quality, firm and tough, with good temperature resistance and excellent salt resistance. At certain salt concentrations, it exhibits good water loss reduction capabilities and maintains a certain rheology.  The viscosity remains almost unchanged when dissolved in salt water compared to being dissolved in fresh water, making it particularly suitable for offshore drilling and deep well requirements.  In addition, carboxymethyl cellulose (CMC) is used in cementing fluids to prevent fluid from entering pores and fractures; and in fracturing fluids to control fluid loss into the oil well.
