What Is The Difference Between Sodium Carboxymethyl Cellulose CMC And Food For Industrial Use?

Sodium Carboxymethyl Cellulose CMC Overview: natural cellulose is chemically modified fiber derivatives, is one of the important water-soluble polymer.

Sodium carboxymethyl celluloseCMC: CMC is a white powder, odorless, tasteless, non-toxic. CMC is a macromolecular chemical, can be water swelling, swelling in water, you can form a transparent viscous glue, in the acidity of the performance of neutral. Solid CMC for light and room temperature are more stable, in a dry environment, can be long-term preservation.

Sodium carboxymethyl celluloseCMC is the most widely used and the largest amount of cellulose in the world today. This product is the sodium salt of cellulose carboxymethyl ether, is anionic cellulose ether, white or milky white fiber powder or particles, density 0.5-0.7 g / cubic centimeter, almost odorless, tasteless, hygroscopic. Easy to disperse in water into a transparent gelatinous solution, insoluble in organic solvents such as ethanol. 1% aqueous solution pH 6.5 ~ 8.5, when pH> 10 or <5, the viscosity of the mortar is significantly reduced, the best performance at pH = 7. The heat stability at 20 ℃ below the rapid increase in viscosity, 45 ℃ change slowly, more than 80 ℃ for a long time heating can make its colloid denaturation and viscosity and performance decreased significantly.

The nature of sodium carboxymethyl celluloseCMC: commonly known as chemical paste. From sodium carboxymethyl celluloseCMC and the amount of water from the modulation, good transparency. Sodium Carboxymethyl Cellulose CMC from a chloroacetic acid and cellulose in the presence of alkali in the role. Tasteless, odorless, asexual white powder. Ordinary etherification degree in the 0.5 ~ 0 or so, the aqueous solution has a high viscosity, the degree of change will not lead to gel, heat and light is very stable. Mainly used as a powder powder sticky material, paper, wood bonding, printing and dyeing with mortar, ceramic production in the powder adhesive, wall paint thickener. Can also be used for food, cosmetics and thickener. Also used as corrugated box adhesive, just add water while stirring can be formulated into a good rheological paste, suitable for continuous production of random coating. Also used for shoe production, cigarette filter, fish meal feed adhesive and so on.
