How to understand the nature and dissolution of sodium CMC

Sodium carboxymethyl cellulose is cellulose in alkaline conditions and sodium monochlorine CH3COOH utility generation. White color to slightly yellow fibrous or granular face; no smelly; wet. Dissolved in water into a colloidal solution, insoluble in alcohol, ether or trichloromethane.CMC

This opening paragraph is just a brief description of the nature and dissolution of sodium carboxymethyl cellulose. It is very difficult to understand, its delicate nature and dissolution. For professional knowledge and skills, to help us understand: Sodium carboxymethyl cellulose is a white color, flocculate face, odorless, no taste, non-toxic, with a melting point of 300 C. Easily soluble in water, forming a photosensitive material-like liquid, and the solution is neutral. CMC

Stability the light and heat. Have moisture absorption. Insoluble in acid, cresol, alcohol, acetone, chloroform, benzene, etc., and insoluble in xyol and diethyl ether. The specific dissolved forms is as follows: First of all. The carboxymethyl cellulose sodium directly mixed with water mixed together, with the manufacturing into a paste of glue liquid after this on the side for use in the next step. CMC

In equipped with layout carboxymethyl cellulose sodium paste, first with mixing facilities equipped with layout principle cylinder added into a certain amount of clean water, in the state of open mixing facilities, the carboxymethyl cellulose sodium slowly, evenly scattered to equipped with layout material cylinder, continuous mixing, let the carboxymethyl cellulose sodium and water complete synthesis, carboxymethyl cellulose sodium can be completely melted. CMC

At the moment of melting sodium carboxymethyl cellulose, why is the need for uniform sprinkling and endless mixing? The main goal is to prevent the moment of sodium carboxymethyl cellulose and water meet, revealing the problem of agglomeration, agglomeration, reducing the dissolution of sodium carboxymethylcellulose, and can improve the dissolution speed of sodium carboxymethylcellulose.
