The importance of the applicable environment of sodium carboxymethyl cellulose

Sodium carboxymethyl cellulose cannot play its good effect in all environments, and it also has some requirements for the using environment. If applied in the right environment, the effect will be better. On the other hand, if the environment is not suitable, its effect cannot be preserved for a long time, and it may cause deterioration. This shows the importance of the environment, so in what environment should this product be applied?

First of all, it is necessary to consider the acid-base environment suitable for sodium carboxymethyl cellulose. It cannot be used in strong acid solutions, nor in soluble iron salt solutions or other metal solutions. In this environment, precipitation often occurs, and it will hinder the normal progress of subsequent reactions. The cost and time to clean up deposits is unacceptable, so deposits should be avoided. The reaction of CMC with gelatin will form coacervate, and this phenomenon will also occur when it reacts with pectin. CMC reacts with collagen to form a complex, which will promote the precipitation of positively charged proteins.

Regular CMC can not be used in a high-concentration salt solution environment, and normal CMC is prone to diluting at high temperatures. Most of the conventional sodium carboxymethyl cellulose will have this phenomenon except for specially treated CMC (such as CMC with a high degree of substitution), which is relatively stable in these two environments. Therefore, in this material environment, the normal use of CMC will be hindered, causing problems in the entire production process. For safe and efficient production, it is important to save time and money by avoiding the use of sodium carboxymethyl cellulose in this environment.

To sum up, when sodium carboxymethyl cellulose is used in a strong acid and high salt environment, its use effect will be limited. Therefore, when using CMC, these aspects should be avoided, so as to avoid obstacles to use, save resources, and improve production efficiency.
