Uses of polyanionic cellulose

 Polyanionic Cellulose (PAC) is an important water-soluble cellulose ether that has been widely used in many industries because of its unique performance characteristics.

1. Textile industry

In the textile industry, polyanionic cellulose can be used as a light yarn sizing agent instead of starch to increase the strength and smoothness of yarns and improve the feel and appearance of fabrics.

2. Paper industry

In the papermaking process, adding polyanionic cellulose to paper pulp can significantly improve the longitudinal strength and smoothness of the paper, while enhancing the oil resistance and ink absorbency of the paper.

3. Daily chemical industry

Polyanionic cellulose is widely used in the daily chemical industry to formulate soaps and synthetic detergents. Its thickening and stabilizing properties help to improve the texture and use effect of the product.

4. Rubber industry

In the rubber industry, polyanionic cellulose is used as a latex stabilizer to help maintain the stability and uniformity of latex, thereby improving the quality of rubber products.

5. Drilling industry

Polyanionic cellulose is used as a fluid loss reducer and tackifier in the drilling industry to prepare drilling mud. It has good water loss reduction, inhibition and temperature resistance, and is especially suitable for salt water wells and offshore oil drilling.

6. Fine chemicals

In fine chemical processing such as coatings, food, cosmetics, ceramic powders, and leather, polyanionic cellulose can be used as a thickness adjuster, emulsion stabilizer, crystallization inhibitor, thickener, binder, suspending agent, and water retention agent. agents and dispersants, etc., to exert their multifunctional properties.

Performance characteristics

Polyanionic cellulose has good thermal stability and salt resistance. The aqueous solution is stable below 80°C and can maintain a certain viscosity for up to 48 hours even at high temperatures close to 150°C. It also has acid, alkali and salt resistance, stable performance within the pH range of 3-11, and is suitable for various polar and harsh environments. Polyanionic cellulose has good solubility and compatibility and is easy to mix with other materials.

Polyanionic cellulose has become an indispensable and important raw material in many industries due to its excellent properties and wide range of applications.
