Main Functional Uses of CMC

CMC function is powerful and widely used. It is a kind of ionic cellulose ether with a wide range of uses. Because of the excellent function of CMC, it is widely used in petroleum, food, medicine, construction and ceramics industries, so it is also called "industrial monosodium glutamate".


In detergents, CMC can be used as anti-fouling redeposition agent, especially for hydrophobic synthetic fiber fabrics, which is superior to carboxymethyl fibers.


CMC can be used to protect oil wells as mud stabilizers and water-retaining agents in oil drilling. The consumption of each oil well is 2.3t for shallow wells and 5.6t for deep wells.


It is used as a sizing agent, thickener of printing and dyeing pulp, textile printing and stiff finishing in the textile industry. Sizing agent can improve solubility and viscous change, and easy desizing; as stiffening agent, its dosage is more than 95%; as a sizing agent, the strength and flexibility of the size film are improved significantly.


CMC can be used as an anti-settling agent, emulsifier, dispersant, leveling agent and adhesives of coatings. It can make the solids of coatings evenly distributed in solvents, and make coatings non-stratified for a long time. It is also widely used in paints.


CMC is more effective than sodium gluconate in the removal of calcium ions as flocculant. When CMC is used as a cation exchange, its exchange capacity can reach 1.6ml/g.


CMC used as a paper sizing agent in the papermaking industry can significantly improve the dry and wet strength, oil resistance, ink absorption and water resistance of paper.


CMC is used as a water-soluble sol in cosmetics and as a thickener in toothpaste. The dosage of CMC is about 5%.


CMC can be used as a flocculant, chelating agent, emulsifier, thickener, water-retaining agent, sizing agent, film-forming material, etc. It is also widely used in the fields of electronics, pesticides, leather, plastics, printing, ceramics, toothpaste, daily chemical industry, etc. Moreover, due to its excellent and extensive use, CMC function is constantly exploring new application fields. The market prospects are very broad.
