Product Description

1.Product introduction of Ceramic Grade Sodium Carboxymethyl Cellulose


CAS: 9004-32-4 

H.S: 39123100

EINECS: 900-432-4

Chemical Formula: [C6H7O2(OH)2OCH2COONa]n

Another name: Carboxymethylcellulose , CMC , CMC Na , Sodium Carboxymethylcellulose , E466 , Cellulose Gum.

Sodium Carboxymethyl Cellulose is anionic cellulose ether with macromolecular structure. It is odourless, tasteless, and non-toxic with white or faint yellow powder or particles. It can easily dissolve in water, and transfer into the colloidal solution; and it cannot dissolve in ethanol, ether, acetone, and other organic solvent.


2.Product Parameter(Specification) of Ceramic Grade Sodium Carboxymethyl Cellulose


Ceramic Grade Sodium Carboxymethyl Cellulose can be used in ceramic body, glazing pulp, and fancy glaze. Used in ceramic body, it is a good strengthening agent, which can strengthen the mouldability of mud and sand materials, facilitate body shaping and increase the folding strength of the green body. Used in glazing pulp and fancy glaze, it is a binder that plays a role of suspending, deflocculating and water holding.


3.Product Feature And Application of Ceramic Grade Sodium Carboxymethyl cellulose


1. Application in ceramic body
When CMC, the unique linear polymers structure, is in the water, its hydrophilic radical combined with water and become the solvation layer and make the CMC molecule be dispersed gradually in the water. CMC high polymers become the network structure supporting by the hydrogen bond and Van der Waals forces, where the bond property is shown. Ceramic body CMC works as the excipient, plasticizer and intensifier in ceramic industry.
* Small usage, high and obvious effect of green body breaking strength
* Increase the processing speed of the green body and reduce the energy consumption
* Good ignition loss, no residue after burning and no infection of original color
* Convenient for technological operation, avoid the flows of crawling and dry spray;
* Good effect of decondensation, increasing the glaze liquidity, and easy for glaze spraying;
* As excipient of blank material to increase the mud plasticity, and make easy for body shaping
* Strong resistance to mechanical wear and few broken molecular chains during ball-milling or mechanical stirring
* As intensifier of blank material to increase the green body breaking strength, enhance its stability and reduce the damage percentage.
* Good suspending and dispersity property. Avoid the coagulation of the lean materials and color pulp pellet, and makes the pulp distribute evenly.
* Evenly evaporate the moisture from the blank material, and prevent from being dried and cracked, especially used in the large-sized blank material of floor tile and polished tile and with good effect

2. Applications in glazing pulp
Ceramic Grade Sodium Carboxymethyl Cellulose (CMC) belongs to polyelectrolytes. It worked as binder and played a role of suspending. When CMC is added into glaze pulp, water seeped into the gel inside, and then its hydrophilic radical combined with water, and makes it swell. In addition, the gel inside is in the hydration swelling conditions, while its outside forms the bound water layer. The micelle is free in the liquid cement at the first dissolution and due to the different and asymmetric size and form, and regularly close up to each other through the Van der Waals forces and then combined with water layer to form the large size network structure, so it has the stronger adhesive capacity.
* Rheological property can be effectively adjusted under the condition of low usage, which brings convenience for enamelling;
* Improve the binding ability of the base body, increase the intensity of the glaze surface significantly and prevent glaze dropping off;
* High smoothness on glaze surface and stable glazing pulp, and reduce the pinholes of the glaze surface after burning
* Excellent performance in spreading and colloid protecting to make the glazing pulp in a stable dispersed status;
* Enhance the surface tension of the glaze materials, prevent water spreading into the base and increase the smoothness of the glaze;
* Avoid the body cracking and printing break in the transportation due to the reduction of the body strength after enamelling.

3.Application in ceramic decalcomania
Ceramic Grade Sodium Carboxymethyl Cellulose (CMC), with good solubility and high transparency of the solution, as well as no residue, possesses the excellent shear-thinning and lubrication, and greatly enhance the decalcomania adaptability and
* Good printing rheology to make printing fluency
* Clear pattern by printing and maintain the consistent color
* High smoothness, good lubrication, excellent effect
* Good water solubility, no residue, no sticking net, no blocking net
* high transparency of solution, and good net permeability
* Excellent thixotropy and lubrication, and greatly enhance the decalcomania adaptability.

4.Application in ceramic penetration glaze
Penetration glaze contains a lot of soluble salt matter with partial acid property. CMC which used in penetration glaze has the excellent stability of acid resistance, salt resistance, and keep the viscosity stable in use or storage, and avoid the chromatic aberration caused by viscosity change, so it greatly improve the stability of the penetration glaze
* Good solubility, no blocking net and good net permeability
* Good compatibility with glaze to make the fancy glaze stable
* Good stability of Acid resistance, alkali resistance and salt resistance to maintain the viscosity stable of the infiltrate glaze

* Good property of the solution levelling, excellent stability of viscosity, and avoid the chromatic aberration caused by viscosity change
