Product Information
PAC is a cellulose ether derivatives from natural cotton fiber through a series of complex chemical reactions and prepared, is one of the important water soluble anionic cellulose ether. With characteristics of "three high and one low": high stability, high temperature resistance, high acid and alkali salt, low usage. Physical properties: the appearance is white, white or light yellow powder or granule, non-toxic and tasteless, hygroscopicity strong, easily soluble in cold water and hot water.
Product Nature
Physical Properties:
· Appearance: White or off-white powder with excellent flowability.
· Solubility: Fast dissolution rate in water, forming a solution with high clarity.
· Rheology: Its aqueous solution exhibits high viscosity and good shear-thinning behavior.Chemical Properties:
· High Degree of Substitution (DS): Typically greater than 0.8, resulting in high anionic charge density along the polymer chain, which enhances its electrochemical stability and resistance to salt and calcium.
· Excellent Salt Tolerance: Effectively hydrates and thickens even in high-concentration NaCl, KCl, and CaCl₂ solutions, performing far better than regular CMC.
· Good Temperature Resistance: Can withstand higher downhole temperatures with good viscosity stability.
· Strong Adsorption & Protective Colloid Action: Adsorbs strongly onto clay particles via hydrogen bonding and ionic interactions, forming a compact, tough, low-permeability filter cake.
· Biological Stability: Resistant to fermentation and mold.
Product Usage
The polyanionic cellulose sodium (PAC) is a kind of water soluble polymer, can be dissolved in water to form a transparent liquid viscosity, can be applied widely in industrial production, the thickening, thickening, bonding, suspension, water retention, emulsification, dispersion, stability and so very good. In oil drilling, digging well engineering, PAC is very easy in water-based drilling fluid, including freshwater, seawater, saturated brine drilling fluid can be, mainly used for offshore drilling and deep well in land, low solid drilling fluid, PAC can significantly reduce filtration loss, reducing thin mud cake, and the page brine have a strong inhibitory effect. For high viscosity (HV), low viscosity (LV), medium viscosity (R) three.
Oilfield Drilling (Primary Application):
· High-Efficiency Fluid Loss Reducer: Used in fresh water, seawater, and saturated brine drilling fluids to provide excellent fluid loss control, protecting reservoir rocks.
· Shale Inhibitor: Stabilizes the wellbore by inhibiting cuttings dispersion and shale hydration through a encapsulating effect.
· Viscosifier: Provides necessary viscosity and yield point for the drilling fluid, improving cuttings transport.
· A key additive for formulating high-performance polymer drilling fluids and KCl-polymer drilling fluids.Construction Materials: Used as a water retention agent, thickener, and set retarder in cement mortars and gypsum products, improving workability and strength.
Personal Care: Serves as a mild thickener and stabilizer in high-end toothpastes, shampoos, body washes, and other personal care products.
Ceramic Industry: Functions as a green body strengthener and binder.
Paints & Coatings: Acts as a thickener and stabilizer in water-based paints.
Safety Matters
Health Hazards:
· Low toxicity, basically harmless to humans. Food-grade and pharmaceutical-grade products can be used in corresponding applications.
· Industrial-grade powder may cause mild irritation to eyes, skin, and respiratory tract. Prolonged inhalation of dust may affect the respiratory system.Handling Protection:
· Must handle industrial-grade powder in a well-ventilated area. Wear a dust mask, chemical safety goggles, and chemical-resistant gloves.
· Avoid dust formation. Avoid contact with eyes, skin, and clothing.
· Wash hands and exposed skin thoroughly after handling.Storage & Transportation:
· Store in a cool, dry, well-ventilated warehouse. Strictly protect from moisture. Due to its hygroscopicity, ensure packages are tightly sealed.
· Store separately from strong oxidizers.
· Food/pharmaceutical-grade products must be stored separately from industrial-grade products and comply with relevant hygiene standards.Fire Fighting:
· Combustible. Dust can form explosive mixtures with air.
· Use water, foam, dry chemical, or CO2 to extinguish fire.
· May decompose at high temperatures, producing fumes including carbon monoxide and carbon dioxide.
