The Amazing Uses and Performance of PAC

Polyanionic cellulose is a polymer material with excellent heat stability, salt resistance, and antibacterial properties. Mud fluids formulated with it exhibit good water loss reduction, inhibition, and temperature resistance, and are widely used in oil drilling, especially in brine wells and offshore oil drilling.
 

Main Uses

Polyanionic cellulose powder has a wide range of applications and can replace carboxymethyl cellulose (CMC) in many industries, providing more stable performance. For example:
*Textile Industry: As a sizing agent for lightweight yarns, replacing starch.
*Paper Industry: Added to pulp to improve the longitudinal strength and smoothness of paper, enhancing its oil resistance and ink absorption.
*Chemical Industry: Used in the formulation of soaps and synthetic detergents.
*Rubber Industry: Used as a latex stabilizer.
*Drilling Industry: As a filtration loss reducer and thickener.
*Other Applications: In the fine chemical processing of coatings, food, cosmetics, ceramic powders, and leather, it is used as a thickness modifier, emulsion stabilizer, crystallization inhibitor, thickener, binder, suspending agent, water-retaining agent, and dispersant.

【Properties】
This product is wettable, soluble in water, and a high-viscosity liquid in neutral or slightly alkaline conditions. It is stable to chemicals, heat, and light. Odorless and tasteless. High-purity polyanionic cellulose is a water-soluble polymer formed by the chemical reaction of cellulose and carboxymethyl anionic groups.
 

【Specific Functions】
1. As a suspension stabilizer for oil drilling mud

Drilling fluids containing High-purity PAC exhibit good stability, reducing fluid loss even at temperatures above 150℃. It helps form a thin, tough, low-permeability filter cake on the wellbore, maintaining low filtration loss.

Drilling fluids containing Drilling Chemical Raw Materials PAC have good rheological and suspension stability, strong resistance to various soluble salt contaminations, and are rarely affected by mold.

Drilling fluids containing PAC polymer have good thickening capabilities. Low-viscosity, high-substitution carboxymethyl cellulose is suitable for high-density drilling fluids and has excellent filtration loss reduction effects.
 

2. As a chemical for oilfield fracturing

It rapidly increases the viscosity of fracturing fluids, efficiently carrying proppant into oil well fractures, establishing permeability channels, rapidly reducing filtration loss, and quickly increasing bottom layer pressure, achieving efficient pressure transmission. The product leaves no residue, does not damage the formation, and can replace guar gum and polyacrylamide.
 

【Product Advantages】

1. Green and environmentally friendly, non-toxic, harmless, and odorless;
2. Good product flowability, strong antibacterial properties, and easy to use;
3. Compared with CMC, PAC has better thickening, suspending, dispersing, emulsifying, binding, salt resistance, water retention, and colloid protection effects;
4. Good thermal stability, acid and alkali resistance, salt resistance, and good solubility and stability;
5. Excellent filtration loss reduction and temperature resistance, suitable for freshwater, saltwater, saturated saltwater, and seawater drilling fluid systems.
