Carboxymethylcellulose is used as a retarder for building concrete in the construction industry. CMC has obvious water retention and thickening effect in concrete, which can prolong the setting time of concrete, improve the setting strength of concrete, and avoid cracks in buildings.

CMC has the functions of bonding, thickening and suspending in the imitation porcelain coatings for the internal and external walls of buildings. When CMC is used to scrape putty on the wall, it can increase the strength of the putty, prevent the putty from cracking, and play a lubrication role.

NotesProducts of various specific indicators can be produced and provided as the customer application requirements.

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

2. After the carboxymethylcellulose sodium is added to the mud, the drilling rig can obtain a low initial cutting force so that the mud can easily release the gas wrapped in it, and the debris is quickly discarded in the mud pit.

3. Drilling mud, like other suspension dispersions, has a certain period of existence. After adding carboxymethyl cellulose sodium, it can stabilize and extend the period of existence.

4. CMC-containing muds are rarely affected by molds, so there is no need to maintain a high pH and no preservatives are needed.

5. Carboxymethyl cellulose is used as a drilling mud washing fluid treatment agent, which can resist the pollution of various soluble salts.

6. CMC-containing mud has good stability and can reduce water loss even at temperatures above 150 ℃.

Paper grade Kingsun Sodium Carboxymethyl Cellulose is an efficient papermaking additive because its aqueous solution has excellent properties such as water retention, film formation, stability, pulp fiber affinity, and adhesion. It makes the paper fibers easy to be compatible, and various fillers are dispersed more evenly in the pulp, which improves the uniformity of the paper. In the surface sizing process, it can effectively improve the strength and flatness of the paper, increase the abrasion resistance, toughness, stiffness, abrasion resistance and surface strength of the paper, and can effectively improve the quality of printing. The uniformity and flatness of the paper have been effectively improved, and at the same time, it can form excellent oil resistance in the paper performance, increasing the qualification rate and yield of the paper. Kingsun CMC can better improve the gloss, whiteness, and brightness of the paper; better improve the surface strength and smoothness of the paper.

The textile industry uses carboxymethyl cellulose as a sizing agent for the sizing of light yarns such as cotton, silk wool, chemical fibers, and blends. Kingsun CMC is a thickener and emulsifier, so it helps to uniformly mix the dye with a high boiling point cleaning solvent and stabilize the dye suspension to prevent precipitation and foam formation. Kingsun CMC has excellent viscosity stability; good fluidity of the solution in the color paste system; better washing performance in the washing process after printing and dyeing.

It can be used in the ceramics industry as an adhesive, plasticizer, suspending agent for glaze and fixing agent.
Carboxymethyl cellulose is mainly used as an excipient, plasticizer, and enhancer in the ceramic green body, which can increase the speed of the green body, prevent cracking of the finished product and facilitate green body molding.

The role of Kingsun CMC in glaze slurry is binder, suspending agent and decoagulant. Add the appropriate amount of carboxymethyl cellulose can improve the grinding efficiency, improve the fluidity of the glaze slurry, increase the strength of the raw glaze, reduce the drying shrinkage of the glaze, and make it firmly bonded to the green body without peeling. The viscosity of the Kingsun CMC aqueous solution increases with temperature And sharply reduced. The viscosity of glaze slurry added with sodium carboxymethyl also changes with temperature, so care should be taken in production to keep the temperature of the glaze slurry from fluctuating too much. In addition, the glaze slurry containing Kingsun CMC has water retention, which makes the glaze layer dry and even, the glaze is flat and compact, and the glaze after burning is smooth and smooth, and the effect is excellent.

Coating grade Kingsun carboxymethylcellulose sodium is generally applicable to various water-based coatings, such as white latex, latex paint, putty, relief paint, natural stone paint, etc.

Coating-grade Kingsun CMC can make coatings not delaminated and can be stored for a long time. It can effectively adjust the rheology of glaze slurry, facilitate glaze application, and keep the glaze slurry in a stable dispersion state. It can effective Improve the strength and smoothness of the glaze to prevent deglazing, ensure the printing process in the printing glaze production, the printed pattern is clear and beautiful.

Carboxymethyl cellulose sodium has good water solubility, and there is almost no insolubility without fiber impurities, and the printing glaze will not block the screen.

In the application of toothpaste, Kingsun CMC is used as a thickener to prevent the solid and liquid components of the toothpaste from separating, so that the toothpaste has a certain consistency, the paste is strip-shaped, has a good skeleton, and does not collapse on the toothbrush.

Toothpaste-grade Kingsun CMC has good rheology and thixotropy, it is easy to transport, and easy to squeeze out of the toothpaste tube. It has suitable viscosity and thixotropy, has good shear-thinning properties and is easy to disperse in paste production And swelling, convenient for filling production; It can be used in pastes with various inorganic salts, and will not significantly degrade paste viscosity over time; It has good and stable heat resistance; due to high uniformity of substitution, Less free fiber, high transparency of the paste; due to better substitution uniformity, strong anti-enzyme performance of the paste; strong water-solubility and water-holding ability, make the paste no oil and water, help pigment And abrasive suspension.

The food industry uses high displacement carboxymethyl cellulose sodium as a thickener for ice cream, canned food, instant noodles, and foam stabilizers for beer. It is used as a thickener and binding agent in processing jams, sugar juices, sherbets, snacks, and ice cream.

Kingsun CMC has many functions in foods such as thickening, suspension, emulsification, stability, shape retention, film formation, puffing, preservation and preservation, acid resistance and health care, etc.. It widely used in the modern food industry. When used in food, it can improve the taste, improve the grade and quality of the product, and extend the shelf life.
