Ceramic Grade CMC

Introduce

Ceramic grade CMC can be used in ceramic bodies, glaze slurries and fancy glazes. 
In the ceramic body, sodium carboxymethylcellulose can be used to improve the molding of the mud, which is beneficial to the molding of the body and increases the flexural strength of the body. It is a good reinforcing agent; in glaze slurry and fancy patterns In the glaze, CMC can be used as a binder to suspend, depolymerize and retain water.

The Core Role of Sodium Carboxymethyl Cellulose in Ceramic Systems

While Ceramic Grade (CMC) does not participate in the sintering reaction during ceramic production, it plays a crucial role in the forming and glazing stages, primarily in the following aspects:
1. Thickening and Rheology Control: Ceramic Grade CMC adhesive significantly increases the viscosity of slurry and glaze systems, giving the slurry good fluidity and controllability, preventing sedimentation and stratification.
2. Suspension Stabilization: By forming a stable polymer network structure, it ensures that solid particles in the glaze are uniformly suspended for a long time, avoiding the phenomenon of "clear water on top and sediment at the bottom."
3. Forming and Bonding: In pressing and slip casting processes, CMC can enhance the bonding force between body particles, improve the strength of wet bodies, and reduce cracks and chipped corners.
4. Improved Glaze Quality: Appropriate addition of ceramic-specific CMC can make glazing more uniform and reduce defects such as pinholes, glaze shrinkage, and glaze runs.
 

CMC for ceramics application segmentation

1. Green Body Reinforcement: Adding 0.1% to 0.5% CMC ceramic adhesive to ceramic green bodies can significantly improve the strength of the green body. Appropriate dosage can increase the strength of the green body by 30% to 50%, greatly reducing the breakage rate during production.
2. Slurry Stabilization: In ceramic slurry preparation, this product is used as a stabilizer and suspending agent. It prevents the sedimentation of solid particles, maintains the uniformity of the slurry, and ensures consistent product quality. This function is particularly important when storing or transporting slurries for extended periods.
3. Slip Casting Application: In slip casting processes, ceramic-grade sodium carboxymethyl cellulose improves the filling and release properties of the slurry by adjusting its rheological properties. It ensures good flowability of the slurry when injected into the mold and allows it to quickly recover its viscosity after filling, preventing the green body from collapsing or deforming.
4. Glaze Application: In ceramic glazes, ceramic-grade sodium carboxymethyl cellulose acts as a carrier and binder, improving the suspension of the glaze slurry and its adhesion to the green body. It ensures a uniform glaze distribution, preventing cracking or peeling of the glaze before sintering.
5. Spray Drying Applications: During spray granulation, this product improves powder flowability and particle strength, increasing the density and uniformity of the pressed green body. This is crucial for automated pressing processes.
