    Product Description

    Carboxymethyl cellulose (CMC) is a non-toxic and odorless white flocculent powder with stable performance and is easily soluble in water. Its aqueous solution is a neutral or alkaline transparent viscous liquid, soluble in other water-soluble adhesives and resins, and insoluble in organic solvents such as ethanol. CMC can be used as adhesive, thickener, suspending agent, emulsifier, dispersant, stabilizer, sizing agent, etc.

    Carboxyl Methyl Cellulose CMC is a water-soluble cellulose derivative. It is also called "sodium salt". It is one of the most commonly used water-soluble cellulose derivatives and has high commercial value.

    CMC is the sodium salt of cellulose carboxymethyl ether, an anionic cellulose ether. CMC is white or milky white fibrous powder or granules with a density of 0.5-0.7 g/cm3, almost odorless, tasteless, and hygroscopic. It is easy to disperse into a transparent gel solution in water, but insoluble in organic solvents such as ethanol.

    Application

    What is a water retaining admixture ?

    Admixtures that can reduce water loss in concrete or mortar are called water retaining admixture.

    Carboxymethyl cellulose (CMC) is a kind of high molecular compound with good solubility, absorbability and water retention. It can effectively reduce the viscosity of concrete, improve the fluidity and pumpability of concrete, and does not affect the strength and durability of concrete.

    In the building materials industry, CMC is used as a retarder, insurance agent, thickener, and adhesive. After adding CMC, the coating has good flexibility, air tightness, and water resistance. It is used as an adhesive and anti-settling agent in the daily chemical industry.

    Adding CMC to concrete can increase the water retention, cohesion, and uniformity of concrete, play a role in retarding settings, and increase durability strength. Wall putty powder CMC. Used to make barricades. Mortar plasticizers for masonry materials and wall treatment, especially the workability, crack resistance, and durability of mortar are greatly improved.

    It is used as a thickening agent in the food industry, as a drug carrier in the pharmaceutical industry, and as a binder and anti-reagglutination agent in the daily chemical industry. In printing and dyeing industry, it is used as a protective colloid for sizing agent and printing paste. It can be used as an oil fracturing fluid component in petrochemical industry. CMC This product has bonding, thickening, strengthening, emulsification, water retention, suspension and other functions.
