In many industrial sectors requiring precise control, polyanionic cellulose (PAC) stands out as a highly efficient and reliable additive due to its unique molecular structure. It does not alter the nature of the system, but rather optimizes the production process and enhances the quality of the final product through precise interactions.

Core Application: Playing a role in key processes

In the oilfield drilling field, the "multi-functional commander" of drilling fluids.

Key Roles: As a crucial additive in drilling fluids, PAC is primarily used for:

Controlling Filtration Loss: Effectively increasing drilling fluid viscosity and forming a dense filter cake on the wellbore, significantly reducing filtration loss, protecting the reservoir, and maintaining wellbore stability.

Carrying Cuttings: Ensuring that cuttings generated during drilling are efficiently carried to the surface, guaranteeing clean and safe drilling operations.

In the construction and building materials industry, cement mortar "performance enhancers"

Key Roles: In dry-mix mortars, putties, and gypsum products, PAC provides:

Water Retention and Thickening: Excellent water retention prevents excessive moisture loss, ensuring full cement hydration; it also provides suitable consistency, improving workability and anti-sagging properties.

Enhanced Bonding: Improves the bond strength between the mortar and the substrate by increasing cohesion.

In the daily chemical industry, ointments are often described as "structural stabilizers."

Key Roles: In products such as toothpaste, shampoo, and lotion, PAC acts as a thickener and suspending agent:

Stabilizing the System: Prevents the sedimentation of solid particles (such as abrasives in toothpaste) and liquid-phase separation, ensuring the uniformity and stability of the product throughout its shelf life.

Regulating Rheology: Imparts suitable paste structure and texture to the product, enhancing the user experience.

Key Advantages: A Specific Manifestation of Reliable Performance

Highly efficient thickening and suspending capabilities

This means that only a small amount of the product needs to be added to achieve the desired viscosity and to suspend particles for an extended period, maintaining the homogeneity of the system.

Excellent water retention performance

This means that in building material applications, it can effectively reduce the rapid evaporation of water or its absorption by porous substrates, providing sufficient time for the hydration reaction of cement-based materials, thereby improving the final strength.

Excellent salt tolerance and chemical compatibility

This means that it can maintain stable thickening and filtration loss reduction properties in high-salinity brine drilling fluids or complex systems containing other electrolytes, making it more widely applicable.

Conclusion

The value of polyanionic cellulose (PAC) lies in its ability as a mature and reliable multifunctional additive to systematically solve various problems you encounter in fluid control—whether it's drilling depth, wall smoothness, glaze uniformity, or paste fineness.
