Description

1. Non-ionic polyacrylamide (NPAM) is a water-soluble polymer made up of acrylamide subunits, which have the molecular formula C3H5NO.
2. NPAM has a high molecular weight range of 5-8 million, and its anionic charge density can vary from 0-10%.
3. Our N830 grade has a low to medium molecular weight and a low charge degree.
4. NPAM is typically used to increase water viscosity or promote flocculation of particles in water.
5. Due to the polar groups on its molecular chain, it can adsorb suspended solid particles in water, bridge particles, or form large flocs through charge, and accelerate their settlement.
6. NPAM is widely used for industrial wastewater flocculation sedimentation, clarification, and treatment, including iron and steel plant wastewater, electroplating wastewater, metallurgical wastewater, coal washing wastewater treatment, and sludge dewatering.
7. It can also be used for drinking water purification and clarification, as well as in sugar and juice mills.
8. NPAM is soluble in water, safe, non-toxic, hydrolytically stable, and not sensitive to pH changes or chlorine. It is non-hazardous, non-flammable, and non-explosive, and can be stored at room temperature. However, it should not be exposed to sunlight. It is slightly acidic, so in case of skin contact, wash it off immediately with plenty of water.

Specifications

Application Fields:

The Oil-displacing Agent is a vital component of tertiary oil recovery in oil fields. It adjusts the rheology of the water used, increasing the viscosity of the driving liquid, improving water drive wave efficiency, and reducing water phase permeability in the ground layer. This helps maintain a consistent flow of oil and water, resulting in the production of approximately 100 to 150 tons more crude oil per ton of macromolecule polyacrylamide product used.

As a raw material for well drilling mud, it acts as an adhesive, improving the service life of drill bits, drill speed, and footage while reducing plug replacement. Additionally, it has a prominent effect on preventing well sloughing, and can be used as fracturing fluid or a plugging agent to control profiles and plug water.

The product can also function as a flocculant, where it adsorbs the solid particles dispersed in water, bridges between particles, and facilitates their sedimentation and separation. It acts as a dispersant in drilling mud treatment, improving lubricity and stability while reducing water loss, effectively preventing sticking and increasing drilling efficiency.

Under the influence of Al3+, Fe3+, Ca2+ and other ions, the product generates cross-linking, and the high molecular compound changes from a linear to a body shape, making it a blocking agent. This product is not water-soluble, and can be adsorbed onto the borehole to block ground layer gaps and prevent drilling fluid leakage.

The product also functions as a lubricant, as it forms a liquid film on the surface of metal or clay particles, changing the friction on the solid surface to liquid friction. This lubricates drill bits and drills, lowers the mud cake friction coefficient, and reduces underground accidents. With a higher hydrolysis degree, it can also change from a flocculant to a fluid loss additive, which reduces cake permeability to keep the borehole stable and minimize filtrate invasion and damage to the pay zone.

Finally, it acts as a shale inhibition agent by forming multipoint adsorption of polymers to crisscross membrane macromolecules, enhancing borehole stability.
