What are the Types of Polyanionic Cellulose?

How is Polyanionic Cellulose Produced?

Polyanionic Cellulose (PAC) is an important chemical additive used in water-based drilling fluids. Preferred to overcome various difficulties encountered during drilling, PAC provides stabilization by increasing the viscosity of the mud and is effective in filtration control. Polyanionic Cellulose Low Viscosity (PAC LV) and Polyanionic Cellulose Regular Viscosity (PAC R) are used. PAC LV is preferred in applications requiring low viscosity, while PAC R is used when higher viscosity is desired. This variety offers flexible and effective solutions for different drilling conditions. You can visit the web address https://aciselsan.com.tr/ for detailed information about Polyanionic Cellulose.

What is the Effect of Polyanionic Cellulose on Mud Viscosity?

The production of Polyanionic Cellulose is achieved by chemically modifying cellulose. Cellulose is a natural polymer and is obtained from plant sources such as cotton and wood pulp. In the production process, cellulose reacts with sodium hydroxide and then with sodium chloroacetate. As a result of this chemical process, the molecular structure of cellulose changes, and it acquires a polyanionic structure. The chemicals and conditions used in the production stage determine the viscosity properties of PAC. Therefore, PAC types with different viscosity levels are produced, and these types serve different functions in drilling operations. Polyanionic Cellulose increases the viscosity of the drilling mud, providing stabilization and controlling fluid loss. When polyanionic cellulose is added to the mud, it interacts with water molecules and forms a gel-like structure. This increases the viscosity of the mud and minimizes fluid loss from underground formations. Specifically, PAC R makes the mud thicker and more viscous, while PAC LV provides filtration control without excessively increasing the mud's viscosity. Polyanionic Cellulose helps the mud remain stable during drilling operations and increases operational efficiency.
