Anionic Polyacrylamide (APAM) Product Introduction

I. Main Introduction

Anionic polyacrylamide is a water-soluble linear polymer with negatively charged active groups such as carboxyl groups on its molecular chain. It possesses excellent flocculation, dispersion, and thickening properties. It is easily soluble in water and insoluble in organic solvents, making it a highly efficient and multifunctional auxiliary agent in water treatment, oil extraction, and textile printing and dyeing.

II. Core Functions

Powerful Flocculation: Adsorbs suspended particles in water through its long polymer chains, forming stable large flocs, accelerating particle sedimentation or filtration separation.

Dispersion and Suspension: Allows for uniform dispersion of sparingly soluble solid particles in liquids, preventing particle aggregation and sedimentation, and improving system stability.

Thickening and Water Retention: Significantly increases the viscosity of aqueous solutions while maintaining good water retention, improving the physical properties of products in coatings, daily chemicals, and other fields.

III. Applicable Uses

Water Treatment: Used as a flocculant for the clarification treatment of industrial wastewater (such as steel, chemical, and printing and dyeing wastewater) and municipal sewage. It can also be used for water purification in waterworks.

In the oil extraction industry: Used as a drilling fluid thickener, filtration loss reducer, and oil displacement agent in tertiary oil recovery to enhance crude oil recovery.

In the textile printing and dyeing industry: Used as a fabric sizing agent to enhance fiber adhesion and reduce breakage rate; also used for decolorization and flocculation treatment of printing and dyeing wastewater.

Other fields: Used as a retention and filtration aid in the paper industry to improve paper strength; used for dewatering tailings in mineral processing.

IV. Key Technical Parameters

Appearance: White or slightly yellow granular or powdery solids with no obvious odor.

Molecular weight: Standard range 8 million-25 million; customizable up to 30 million for high-demand applications. Higher molecular weight results in stronger flocculation.

Degree of hydrolysis: The content of carboxyl groups in the molecular chain, standard range 5%-40%. Higher degree of hydrolysis indicates better flocculation adaptability to high-turbidity wastewater.

Usage Concentration: Dilute with clean water. The standard concentration for water treatment is 0.1%-0.3% (1-3g product dissolved in 1L of water). In the oil extraction field, the concentration can be adjusted to 0.5%-1% depending on the process.

V. Safety Instructions

Anionic polyacrylamide itself is non-toxic. Although its monomer (acrylamide) has some toxicity, the residual monomer content after polymerization in legitimate products is extremely low (≤0.05%), meeting national safety standards. Under normal operation and use, it poses no harm to humans or the environment. Avoid prolonged inhalation of the product powder and do not ingest.

VI. Precautions for Use

Use clean tap water at room temperature for dissolution. Avoid water temperatures exceeding 40℃ (high temperatures can cause polymer degradation and reduce effectiveness). Control the stirring speed at 150-200 rpm (too fast stirring can break chains, too slow stirring will result in incomplete dissolution).

The dissolved solution must be used within 24 hours. Prolonged storage will lead to degradation and performance decline.

The dosage needs to be determined through small-scale testing (the standard dosage for water treatment is 0.5-3 ppm). Excessive dosage may cause the water to become viscous, affecting the treatment effect.

It is recommended to wear a dust mask and latex gloves during operation. If the powder gets into the eyes, rinse immediately with plenty of water. If ingested, seek medical attention immediately and inform the doctor of the product’s ingredients.

Store in a sealed container in a cool, dry, and well-ventilated place, avoiding moisture and clumping (clumping will dissolve after crushing without affecting the effect, but the dissolution rate will be slower).
