How to use sodium carboxymethyl cellulose

It is understood that sodium carboxymethyl cellulose is widely used in food industry, pharmaceutical industry, daily chemical industry, printing and dyeing industry, petrochemical industry and other industries. In order to make sodium carboxymethyl cellulose play a good role, how should it be used.

How to use CMC sodium

The sodium carboxymethyl cellulose is directly mixed with water to prepare a paste, which is then used for standby. When preparing CMC sodium paste adhesive, first add a certain amount of clean water into the batching tank with mixing device. When the mixing device is turned on, slowly and evenly sprinkle CMC into the mixing tank, and keep stirring, so that CMC and water are completely integrated and CMC can be fully dissolved.

When dissolving sodium carboxymethyl cellulose, the reason why it should be evenly spread and stirred continuously is “to prevent the problems of agglomeration and agglomeration, and reduce the dissolution of CMC” when sodium carboxymethyl cellulose meets water, and improve the dissolution rate of CMC. The mixing time is not consistent with the time of complete dissolution of sodium carboxymethyl cellulose. It is two concepts. Generally speaking, the stirring time is much shorter than the time required for the complete dissolution of CMC. The time required for the two depends on the specific situation.


In a word, when carboxymethyl cellulose sodium is used, we should pay attention to the reaction of sodium carboxymethyl cellulose with strong acid solution to form iron salt, and there are certain taboos when it is used with other metals such as aluminum, mercury and zinc. Therefore, in order to use carboxymethyl cellulose sodium normally and play a normal role, we should avoid using it with its substance
