Ceramic Grade carboxymethyl cellulose

Carboxymethyl Cellulose (CMC), particularly the ceramic grade, is a water-soluble polymer derived from cellulose. It is widely utilized in the ceramic industry due to its excellent thickening, suspending, and binding properties. When added to ceramic slurries, it improves the mechanical strength of green and dry ceramic bodies and enhances the performance of glazes. Its role is critical in controlling the rheology of ceramic pastes, which ensures uniformity and quality in the final products. Ceramic grade CMC is also valued for its ability to increase the plasticity of the clay, making it easier to mold and shape. It acts as a film-former, providing a strong yet flexible matrix that holds the ceramic particles in place during the drying and firing stages, leading to a refined and sturdy finish.

Ceramic Grade carboxymethyl cellulose applications

Ceramic Grade Carboxymethyl Cellulose (CMC) is a versatile additive used extensively in various applications within the ceramics industry. Its primary function is as a rheology modifier and binder, crucial in the production of ceramic tiles, sanitary ware, and tableware.

In tile manufacturing, CMC is used to improve the plasticity and workability of the clay body. It aids in achieving the desired consistency in tile slip, ensuring uniform thickness and dimensional stability. This results in reduced warping and cracking during the drying and firing stages. CMC’s water-retention property helps maintain the moisture content in the clay, facilitating easier shaping and forming.

For sanitary ware, such as toilets and basins, CMC is vital in slip casting. It enhances the fluidity of the ceramic slip, allowing for smoother casting and a higher quality surface finish. The improved binding ability of CMC reduces defects and increases the strength of the green body.

In tableware production, CMC is used to enhance the adhesive properties of glazes. It ensures even application of glazes and prevents sagging or running during firing, leading to a superior aesthetic finish. Additionally, CMC’s stability under high-temperature conditions makes it ideal for use in high-temperature firing processes.
