Physical and chemical properties:
1. Appearance: White or slightly yellow flocculent fiber powder or white powder, odorless and non-toxic;
2. Carbonization temperature: 252 ºC;
3. Color change temperature: 227 ºC;
4. Surface tension: 2% aqueous solution surface tension 71mn/n;
5. Solubility: Easily soluble in cold or hot water, forming a transparent solution with a certain viscosity. The solution is neutral or slightly alkaline, insoluble in organic solvents such as ethanol, ether, isopropanol, and propanol, and soluble in ethanol or acetone solutions containing 60% water. It has hygroscopicity and is stable for photothermal stability. Its viscosity decreases with increasing temperature. The solution is stable at a pH of 2-10, with a pH lower than 2. There is precipitation of the national substance, and the viscosity decreases when the pH value is below 10.
Application area:
The application areas of CMC cover food, toothpaste, petroleum drilling, mining, ceramics, papermaking, printing and dyeing, welding, detergents, building materials, and other industrial fields. As a protective colloid, coating grade CMC provides excellent pigment adhesion effect, improves the viscosity, leveling, splash and sagging resistance of latex coatings, and enhances the workability of coatings. Polyanionic cellulose used in drilling fluid has excellent filtration loss reduction performance. Ceramic grade CMC serves as a binder for raw materials, improving the plasticity of clay and serving as a flow control agent for glaze to prevent shedding and tear marks before firing. Mining grade CMC is a binder and flotation inhibitor for pellets in the mining industry.
Mainly introduce the following three application areas:
1.Applied to the food industry:
CMC is odorless, odorless, non-toxic, can be stored for a long time without spoilage, has high viscosity, strong shape retention, and is easy to dissolve. It can be used for food processing. Used as a viscosity agent, increment agent, stabilizer, solidifying agent, film forming agent, and so on.
2.Used in the synthesis of detergents and soap industry:
CMC has the properties of emulsification and protective colloid, so it is one of the best active additives for synthesizing detergents. Its role in the washing process is to prevent the re attachment of dirt. When making slag soap, adding CMC not only has the same mechanism and advantages as detergents, but also greatly improves the quality of soap, making it flexible and easy to process and press.
3. Used in the daily chemical industry:
CMC can serve as a stabilizer and emulsifier in toothpaste, skincare cream, and shampoo, regulating viscosity and stabilizing foam. Enhance the cleaning ability and make the quality delicate. CMC is also an ideal adhesive for making mosquito coils, shoe uppers, paper boxes, pencils, and tobacco tablets.
