New research progress rapidly dissolving sodium carboxymethyl cellulose

- Aug 21, 2014 -

We have been very familiar with sodium carboxymethyl cellulose is soluble in cold water product, which is one of its very excellent features, just by virtue of this feature is enough to applications of sodium carboxymethyl cellulose expand the space.

There are polyanionic cellulose, sodium carboxymethyl cellulose is in fact belong to the anionic cellulose ethers, their physical characteristics were as follows: Appearance is white or slightly yellow powder flocculent fiber or white, odorless, tasteless, non-toxic; soluble in cold water or hot water, to form a transparent solution having a certain viscosity. Was generally neutral or slightly alkaline, insoluble in ethanol, ethyl ether, isopropyl alcohol, acetone and other organic solvents, but can be dissolved in aqueous ethanol or acetone solution of 60%. Sodium carboxymethyl cellulose is hygroscopic, it is the general solution viscosity decreases with increasing temperature, PH value of the solution is between 2-10 and stable, when the PH of less than 2, a solid precipitated in the solution, when the PH value is greater than 10, when the solution viscosity.

So how can we make fast dissolving sodium carboxymethyl cellulose, but also summed up the issue before me. Repeat once again. Appropriate temperature can promote its dissolution, but the temperature will be counterproductive. Stir, fineness, etc. These methods usually used in the laboratory is no longer narrative. It is worth mentioning that the new point of view, a problem if you want to quickly dissolve the sodium carboxymethyl cellulose, which can not be overlooked is that the dispersion, only dispersed uniformly in water, the dissolution speed will be shortened to some extent. Of course, there are chemical methods, but considering the stability of the product, you also need to take a different chemical treatment for the industry.
