CMC has a good thickening, dispersion, emulsion, suspension, such as the role of protective colloid, and physical harm, and therefore food, medicine, daily chemical, petroleum, paper, textiles, construction and other fields is widely used in production. 

 ⑴ for oil and gas drilling, wells and other projects 
 ⑵ for the textile dyeing industry, textile industry to CMC as a sizing agent for cotton, silk wool, chemical fiber, blended and other strong materials veil sizing; 

 ⑶ CMC for the paper industry can be used in the paper industry, paper-based smoothing agent, sizing agent. In the pulp with 0.1% ~ 0.3% of the CMC can enhance the tensile strength of paper 40% to 50%, 50% degree of compression fracture, rubbing increased 4 to 5 times. 

 (4) CMC added synthetic detergents can be used as dirt in the adsorbent; household chemicals such as toothpaste industry with the use of CMC aqueous solution of glycerine toothpaste gum; the pharmaceutical industry as a thickener and emulsifier; CMC aqueous solution and used as tackifying planktonic dressing and so on. 

 ⑸ can do for the ceramic industry in rough adhesives, plasticizers, glaze suspension, fixing agent. 

 ⑹ used in construction, improve water retention and strength
