Cationic Polyacrylamide (CPAM) Product Introduction:

I. Main Introduction

Cationic polyacrylamide is a linear polymer with positively charged active groups on its molecular chains. It possesses extremely strong adsorption bridging and charge neutralization capabilities. It is readily soluble in water but insoluble in organic solvents, making it a highly efficient functional additive in water treatment, papermaking, and mineral processing.

II. Core Functions

Adsorption Bridging: Through its long polymer chains, it adsorbs and connects fine particles and colloids in water, forming large flocs that accelerate sedimentation or filtration.

Call Neutralization: Its positive charge neutralizes negatively charged colloids and suspended solids in wastewater, disrupting colloidal stability and achieving rapid destabilization and coagulation.

Enhanced Solid-Liquid Separation: Improves sludge dewatering and wastewater clarification efficiency, reducing the turbidity and solids content of treated water.

III. Applicable Applications

Water Treatment: As a sludge dewatering agent (suitable for municipal sludge, chemical sludge, dyeing and printing sludge, etc.), and a clarifying agent for domestic sewage and industrial wastewater (such as papermaking wastewater, food wastewater, and slaughterhouse wastewater).

Papermaking: Used as a paper dry strength agent, retention aid, and filter aid to improve paper strength, reduce fiber loss, and improve paper sheet formation.

Mineral Processing: As a mineral flotation agent or settling agent to facilitate the separation of mineral particles from water and improve mineral processing efficiency.

Other Applications: Used as a thickener and oil displacement agent in oilfield extraction, and for dye wastewater treatment in the textile industry.

IV. Key Technical Parameters

Appearance: White or slightly yellow granular or powdery solid.

Molecular Weight: Standard range 8 million-12 million; lower molecular weights can be customized for some special applications.

Degree of Hydrolysis: Cationicity (corresponding to the conventional concept of degree of hydrolysis) is typically 5%-80%, and the appropriate model can be selected according to the wastewater properties (such as sludge charge and wastewater turbidity).

Usage Concentration: Dilute according to the application scenario. In water treatment, the standard dilution concentration is 0.1%-0.3% (i.e., 1-3g of product dissolved in 1L of water). In papermaking and mineral processing, the concentration can be fine-tuned according to the process.

V. Safety Instructions

Cationic polyacrylamide itself is non-toxic, but its monomer (acrylamide) has a certain degree of toxicity. After polymerization, the residual monomer content in legitimate products is extremely low (usually ≤0.05%), meeting national environmental and safety standards. Under normal use, it poses no harm to humans or the environment; however, prolonged direct contact with the powder should be avoided (it may irritate the respiratory tract), and it is prohibited from being ingested.

VI. Precautions for Use

Use clean tap water for dissolution, with the water temperature controlled between 10-40℃ (avoid high temperatures or ice water to prevent affecting the dissolution effect). Maintain a stirring speed of 200-300 rpm (too fast a stirring speed can easily cause polymer chain breakage, reducing effectiveness).

Use the dissolved solution within 24 hours to avoid degradation and inactivation due to prolonged storage.

The dosage needs to be determined through small-scale testing (usually 0.5-5 ppm). Excessive dosage may cause water turbidity and increase treatment costs.

It is recommended to wear a dust mask and latex gloves during operation. If the powder accidentally 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 to prevent moisture and clumping (clumping will require crushing and dissolving; this will not affect the effectiveness, but the dissolving speed will be slower).
