What Are The Common Properties Of Sodium Carboxymethyl Cellulose Have?
Jun 18, 2016

Sodium carboxymethyl cellulose is a white powder, it is relatively widely used in all aspects of living, it is not only a macromolecular chemical substance, or an additive, then in addition to these, as well as sodium carboxymethyl cellulose What are our common nature of it?

1. hygroscopic properties: sodium carboxymethyl cellulose has good moisture absorption, it can appreciate the degree of moisture associated with temperature and relative humidity of the atmosphere, but its hygroscopic certain restrictions, in carboxymethyl cellulose Su sodium humidity and ambient humidity reaches a critical balance, the sodium carboxymethyl cellulose is no longer hygroscopic, but remains a state gelatinous substance.

2. Chemical reaction: an aqueous solution of sodium carboxymethyl cellulose can react chemically with a lot of substance, such as calcium material and it will not produce this substance magnesium coexistence should be some precipitation, and sodium carboxymethyl cellulose aqueous acid in the face will appear a small amount of precipitation, but in general acid-type aqueous solution of sodium carboxymethyl cellulose acid solution will have some resistance.
