Product Descriptions

Chinese name: Polyacrylamide (commonly known as flocculant or coagulant)

English name: Polyacrylamide (PAM)

Classification: Cationic Polyacrylamide, Anionic Polyacrylamide, Non Ionic Polyacrylamide, Amphoteric Polyacrylamide.
Product Appearance: Solid is white powder or particle, liquid is colorless viscous colloid.

Applications

PAM is an important water-soluble polymer that possesses properties such as flocculation, thickening, shearing, drag reduction, and dispersibility. These properties have different emphases depending on the derivative ions. Therefore, it is widely used in various sectors such as oil extraction, mineral processing, coal washing, metallurgy, chemical industry, papermaking, textiles, sugar production, medicine, environmental protection, building materials, and agricultural production.

Advantages

• Flocculation: It can neutralize suspended matter through electricity and achieve flocculation.

Adhesive properties: Adhesive properties can be achieved through mechanical, physical, and chemical means.

• Resistance reduction: It can effectively reduce the frictional resistance of fluids, and adding a small amount of PAM to water can reduce resistance by 50-80%.

Thickening: PAM has a thickening effect under both neutral and acidic conditions. If the pH value is above 10, PAM is prone to hydrolysis. When it forms a semi mesh structure, thickening will be more pronounced.

Usage

Granular polyacrylamide flocculant cannot be directly added to wastewater. It must be dissolved in water before use.

The water used to dissolve granular polymers should be clean tap water, not sewage. Generally, tap water is suitable for preparing polymer solutions. Strong acid, strong alkali, and high salt water are not suitable for preparation. Normal temperature water is sufficient and generally does not require heating. Dissolve slowly when the water temperature is below 5 ℃. The increase in water temperature accelerates the dissolution rate, but temperatures above 40 ℃ will accelerate the degradation of polymers, affecting the effectiveness of use.

The recommended concentration of polymer solution is 0.1% -0.3%, which means adding 1g to 3q of polymer powder in 1 liter of water.

Storage conditions

1. Solid can be stored for more than 2 years in a dry and cool place The storage time of the solution is limited, and iron containers should not be used for storage.

2. The product itself is not toxic, only harmful when inhaled at a dose greater than 0.5%. The residual acrylamide monomer in the product is toxic, and its application in food must be strictly controlled. The specific advertising volume is determined by the actual number of experiments conducted by users.

Attentions

1. This product is easily soluble in water and decomposes when the temperature exceeds 120 ℃. Attention should be paid to moisture prevention during transportation and storage.
