Robust green bodies, lustrous glazes - advanced performance ceramic industrial additives CMC

Industry Challenges

The ceramic industry is undergoing a significant transformation, striving for high-quality development while facing several challenges, including market competition, technological limitations, and environmental pressures. At this critical stage, the need for reliable, high-performance materials is more important than ever.

Fortune Biotech’s Ceramic Grade CMC offers an innovative solution to meet the evolving needs of the ceramic industry. Known for its high purity, low ash content, excellent solubility, and strong compatibility, our CMC is designed to enhance the quality and efficiency of ceramic production. One of its standout features is its clean burning property, ensuring that almost no residue remains after high-temperature calcination. This unique characteristic guarantees superior density and quality in the final ceramic product, which is crucial for meeting industry standards.

Our Ceramic Grade CMC is ideal for a wide range of ceramic manufacturing processes. Whether you are involved in slip casting, extrusion molding, glaze spraying, or screen printing, our product provides the necessary stability and performance to achieve precise results. The ability to deliver excellent viscosity control and enhanced flowability makes our CMC a trusted choice for ceramic applications that demand the highest standards of precision and quality.

In slip casting, Fortune Biotech’s Ceramic Grade CMC improves the consistency and fluidity of ceramic slips, ensuring smooth, uniform casting without defects. For extrusion molding, it enhances the plasticity of the material, allowing for the easy formation of complex shapes. When it comes to glaze spraying, our CMC helps achieve a more uniform, even coating, while in screen printing, it ensures the fine details of designs are reproduced accurately and without distortion.

Our ceramic grade CMC is available in a variety of specifications, tailored to meet the specific needs of different manufacturing processes. It supports a cleaner, more efficient production cycle while ensuring superior performance in the final ceramic products.

With Fortune Biotech’s Ceramic Grade CMC, manufacturers can address the challenges of high-quality production and stay competitive in the fast-evolving ceramic industry.

Application Cases

Case 1: Ceramic Body Reinforcing Agent

Challenge:
Unfired ceramic bodies (green bodies) have very low mechanical strength and are prone to breakage or chipping during processes such as transfer, trimming, and glazing, leading to low yield rates.

CMC Solution:
As a binder added to the body formulation, CMC’s long-chain molecules form flexible bridges between particles. After drying, it firmly binds the loose ceramic powders together, increasing the flexural strength of the green body by 2-3 times and significantly improving the yield rate during handling.

Case 2: Stabilizer and Rheological Modifier for Glaze Slurries

Challenge:
Glaze slurries are suspensions composed of various mineral raw materials with different densities. They are prone to sedimentation and agglomeration after prolonged standing, and their viscosity is unstable. This can result in uneven glaze layer thickness during spraying or dipping, leading to defects such as running glaze or pinholes.

CMC Solution:
As a suspending and thickening agent for glazes, CMC increases the viscosity and stability of the glaze slurry, ensuring uniform suspension of glaze particles. At the same time, it imparts favorable thixotropic properties to the glaze, allowing it to flow smoothly and evenly cover the body surface during application. Upon standing, the viscosity quickly recovers, preventing sagging and forming a uniform, smooth glaze layer.

Case 3: Plasticizing Lubricant for Extrusion Molding

Challenge:
In the production of extruded products such as honeycomb ceramics and ceramic tubes, poor plasticity and high friction of the raw material can lead to difficulties in extrusion, high energy consumption, and issues such as cracking and surface roughness in the final products.

CMC Solution:
CMC adsorbs onto the surface of ceramic particles, acting as a lubricant that significantly reduces the friction coefficient between particles and between the raw material and the mold wall. At the same time, its water-retention properties improve the plasticity of the material, resulting in a smoother extrusion process, a smoother product surface, and a denser structure.

Case 4: Ceramic Decal Printing Ink

Challenge:
Ceramic decal printing requires a binder that can carry pigments, provide suitable viscosity and drying speed, and burn off completely during firing.

CMC Solution:
Due to its excellent film-forming ability, strong adhesion, and clean-burning properties, CMC is used as the primary binder in ceramic printing inks (also known as “printing oil”). It effectively adheres the pigments to the transfer paper. After being transferred to the ceramic body, it decompletely decomposes during firing, leaving behind only the vibrant design.
