Nonionic Polyacrylamide (NPAM) Product Introduction

I. Main Introduction

Nonionic polyacrylamide is a water-soluble polymer material whose molecular structure does not contain strongly polar ionic groups. Leveraging its molecular chain adsorption capacity and film-forming properties, it plays the role of a “functional regulator” in many industries. It is not only easily soluble in water but also possesses excellent chemical stability, making it suitable for complex application scenarios.

II. Core Functions

Adsorption and Agglomeration: Through the active adsorption sites on its molecular chains, it captures dispersed fine particles and colloids in water, agglomerating them into large flocs that are easy to settle and filter, efficiently solving solid-liquid separation problems.

Thickening and Shape Retention: It can significantly increase the viscosity of aqueous solutions while forming a uniform film on the solid surface, possessing both water retention and moisture locking properties as well as binding and fixing effects, optimizing product or process performance.

Synergistic Enhancement: It can be used in combination with inorganic flocculants such as aluminum salts and iron salts. Through the synergistic effect of “adsorption + charge neutralization,” it expands the application range of water treatment and improves purification efficiency.

III. Applicable Applications

Water Treatment: Used as a flocculant for organic wastewater from food processing and slaughtering to achieve rapid sedimentation of impurities; also used in tap water pretreatment to improve water quality in subsequent filtration stages.

Textile Industry: Serves as a “bonding aid” in fabric sizing, allowing the sizing agent to adhere tightly to the fiber surface, enhancing the fabric’s tear resistance; it can also treat dyeing and printing wastewater, assisting in the separation of pigments and impurities.

Agriculture: Acts as a soil “water-retaining amendment,” reducing water evaporation and improving soil aggregate structure; it can also serve as a “slow-release carrier” for fertilizers and pesticides, extending their effective period and reducing waste.

Other Applications: In the paper industry, it can improve pulp fiber retention and paper strength; in mineral processing, it can accelerate the separation of useful minerals from water in the pulp, improving beneficiation efficiency.

IV. Key Technical Parameters

Appearance: White or slightly yellow granular or powdery solid, odorless, easy to store and feed.

Molecular weight: Standard specifications cover 6 million to 12 million; products with specific molecular weights can be customized according to specific process requirements.

Degree of hydrolysis: Due to molecular structure characteristics, the degree of hydrolysis is generally low, usually controlled below 5%. Its function mainly relies on the physical adsorption of molecular chains.

Usage concentration: For water treatment, the standard dilution ratio is 0.1%-0.3% (i.e., 1-3g of product dissolved in 1L of water); if used for thickening, the concentration can be adjusted to 0.3%-0.5%.

V. Safety Statement

Nonionic polyacrylamide itself is non-toxic. Although its raw material monomer acrylamide has a certain degree of toxicity, in properly manufactured products, the monomer residue is strictly controlled within the national standard range (≤0.05%) after polymerization. Under normal operation and use, it will not cause harm to human health or the environment. However, avoid prolonged inhalation of the product powder; ingestion is strictly prohibited.

VI. Precautions for Use

Use clean tap water at room temperature for dissolution. The water temperature should not exceed 40℃ (high temperatures will damage the molecular chain structure and reduce effectiveness). Maintain a stirring speed of 100-150 rpm to ensure the product is fully dissolved and does not degrade.

It is recommended to use the dissolved solution within 24 hours. Prolonged storage will lead to molecular chain degradation, resulting in decreased flocculation and thickening properties.

The dosage needs to be determined through small-scale testing (generally 0.5-3 ppm for water treatment). Excessive dosage can easily cause the water to become viscous, which will affect subsequent treatment processes.

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 package in a cool, dry, and ventilated environment to prevent moisture and clumping (clumping can be crushed and redissolved without affecting the effect, only the dissolution speed will be slightly slower).
