Application of CMC in Industry (II)

Carboxymethyl cellulose (CMC), one kind of cellulose ethers' product with the largest output and the widest uses, is the most convenient one to use in industry, commonly known as "industrail monosodium glutamate".

1. Application in Textile and Dyeing Industry

CMC is used as a sizing agent in textile industry for sizing fine gauze such as cotton, silk wool, chemical fiber and blended yarn.

2. Application in Paper-Making Industry

Carboxymethyl cellulose CMC is used as a paper smoothing and sizing agent in paper industry. Adding 0.1%-0.3% CMC to the pulp enhances the tensile strength by 40%-50% and increases the crushing strength by 50% and the kneading property by 4-5 times.

3. CMC can be used as dirt adsorbent in synthetic detergents

In daily chemical industries such as toothpaste industry, the glycerin aqueous solution of CMC is used as gum base of toothpastes. In pharmaceutical industry, it is used as thickener and emulsifier. When CMC aqueous solution is tackifying, it can be used for flotation and mineral processing.

4. Application in Ceramic Industry

In ceramic industry, CMC can be used as the blank's adhesive, plasticizer, suspending agent, fixing agent, etc.

5. Application in Construction Industry

CMC used in construction industry can improve the water-retention and the compressive strength of concrete.

6. Application in Food Industry

The food industry adopts CMC with high degree of substitution as thickener for ice cream, can and instant noodles; stabilizer for foam in beers; and as thickener and binder for jams, syrups, fruit juice, desserts, ice-creams, etc.

7. Application in Pharmaceutical Industry

In pharmaceutical industry, CMC with proper viscosity is selected as the adhesive and disintegrant of tablets, and suspending agent of suspensions.
