Food-grade CMC powder
Sodium carboxymethyl cellulose, abbreviated as CMC or CMC-Na, is a water-soluble polymer compound obtained by chemical modification of natural cellulose. It belongs to the anionic cellulose ether class and exhibits good solubility and functional stability in water, making it one of the most widely used cellulose derivatives in industrial and civilian applications.
CMC for batteries
Battery-grade CMC exhibits excellent alkali stability, does not hydrolyze within the 15-45°C range, and possesses good acid and salt resistance. The resulting liquid is highly stable, making it suitable for alkaline batteries as an electrolyte additive, and also for zinc-manganese batteries.
Ceramic grade sodium carboxymethyl cellulose
Sodium carboxymethyl cellulose (CMC-Na) is a commonly used water-soluble polymer compound with a white or pale yellow powder appearance. Due to its excellent thickening, water-retaining, and binding properties, CMC is widely used in ceramic glazes. Especially in the production of high-quality sanitary and architectural ceramics, it not only improves the quality of the glaze slurry but also significantly enhances the smoothness and evenness of the finished glaze surface.
CMC ceramic adhesive
CMC ceramic adhesive can burn completely during high-temperature firing, leaving no residue. The tiny pores created after combustion help gases escape, making the internal structure of the blank more compact and the surface smoother, which is beneficial for subsequent glazing and sintering.
CMC for ceramics
Adding a small amount of CMC to ceramic bodies can significantly improve the plasticity of the clay, facilitating body shaping. It also improves flexural strength, increasing the flexural strength of the green body and reducing breakage. It exhibits good ignition loss, leaving no residue after firing. It has good suspension properties, preventing the agglomeration of lean raw material particles. It has good abrasion resistance, exhibiting strong resistance to mechanical abrasion and minimal molecular chain damage during mechanical stirring.
Textile Printing and Dyeing CMC
CMC (Printing and Dyeing Grade) is a commonly used auxiliary agent in the printing and dyeing industry, highly favored for its unique properties and functions. The following will provide a detailed analysis of the specific applications of printing and dyeing grade sodium carboxymethyl cellulose in the industry.
Textile printing and dyeing grade CMC
In the textile printing and dyeing process, dyes need to be evenly distributed and stably adhered to the fabric surface. If the dye liquor or printing paste is too fluid, problems such as bleeding, blurred patterns, and uneven coloring can easily occur. Sodium carboxymethyl cellulose is one of the important auxiliaries for solving these problems.
CMC Textile Printing grade - Cellulose Ethers
Textile printing and dyeing grade CMC primarily serves the two core stages of printing and dyeing, enhancing process effects and efficiency through its thickening, stabilizing, leveling, and dyeing aid functions. In printing processes, it is one of the mainstream printing pastes, which can be used alone or in combination with sodium alginate, tamarind gum, etc., as a color paste carrier to lock in moisture and dye, preventing screen clogging and color paste flow during printing, while improving screen penetration and leveling.
Ceramic grade CMC adhesive
CMC can be used as an anti-settling agent, emulsifier, dispersant, leveling agent, and binder in coatings (putty/powder). It enables the solids content of the coating to be evenly distributed in the solvent, preventing the coating from separating over a long period. It is also widely used in paints.
Pharmaceutical CMC
Pharmaceutical CMC is primarily used in oral formulations. In tablet manufacturing, sodium carboxymethyl cellulose can be used as a disintegrant in both direct compression and wet granulation processes.
CMC For Toothpaste
CMC plays a crucial role in toothpaste. First, as a thickener, CMC significantly improves the texture of toothpaste, giving it a certain viscosity and a good framework, making it easier for users to control during use. Second, the suspending properties of CMC prevent the separation of solid components (such as abrasives) from the liquid components in toothpaste, ensuring the stability and uniformity of the toothpaste.
Oil Drilling Grade CMC
When used as a cementing fluid, CMC prevents fluid from entering pores and fractures; when used as a fracturing fluid, it controls the flow of fluid into the well.
