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.
Overall, Ceramic Grade CMC is essential for improving the quality and efficiency of ceramic products, ensuring consistency, and reducing waste in the manufacturing process.
- By selecting suitable reaction conditions and a distribution of substituents in the product, the formation of CMC gel particles on the sieve during glaze paste fineness testing is greatly reduced.
- Free of colored impurities and completely combustible, ensuring the ceramic products have a clean, blemish-free glaze after firing.
- It stabilizes the chemical and physical properties of the glaze paste, enhancing the efficiency of glaze preparation.
- Increases the strength of the raw glaze, reduces dry absorption of the glaze, and minimizes defects like textile rolling glaze and glaze omission, ensuring a strong bond between the body and the glaze, facilitating processing operations.
- Ensures a uniform glaze layer, resulting in a flat, finely finished glaze surface that is smooth and even after firing.
- Exhibits excellent rheology, improving the flow properties of the glaze paste, which is beneficial for spray glazing operations.
- The amount of CMC added influences the concentration in the glaze paste; regardless of using high, medium, or low viscosity CMC, the viscosity of the glaze paste increases with the addition of more CMC.
