Application of sodium carboxymethyl cellulose

When preparing carboxymethyl cellulose paste, first use the stirring device to add a certain amount of water into the batching tank. After opening the stirring device, slowly and evenly spread carboxymethyl cellulose into the batching tank, and continue to stir to make it uniform. When CMC and water are completely fused, CMC can be completely melted.

When dissolving carboxymethyl cellulose, it should be evenly distributed and continuously stirred, in order to prevent caking and agglomeration of carboxymethyl cellulose when it meets with water, reduce the amount of dissolved carboxymethyl cellulose and improve the dissolution rate of carboxymethyl cellulose.

The stirring time is different from the complete melting time of CMC. They are two concepts. In general, the stirring time is much shorter than the time required for complete melting of CMC, depending on the circumstances.

The basis of determining the stirring time is: when CMC is uniformly dispersed in water and there is no obvious large mass, the stirring can be stopped, and CMC and water can permeate and fuse under static state.

Basic introduction to the time required for complete melting of carboxymethyl cellulose:

There is no solid-liquid separation between CMC and water. After mixing, the paste should be in a uniform state, and the surface should be smooth.

The color of the mixed paste is nearly colorless and transparent, and there is no granular object in the paste. The time from putting CMC into the mixing tank and mixing with water to completely dissolving CMC is 10 to 20 hours.
