How to use polyacrylamide correctly?

Jun 11, 2024

Polyacrylamide is a commonly used synthetic polymer compound with a wide range of applications, including water treatment, soil improvement, oil extraction, paper manufacturing, etc. The following is a general guide to the correct use of polyacrylamide:

1. Safe operation: Before using polyacrylamide, be sure to read and follow the safety data sheet (MSDS) and operation instructions provided by the product supplier. Make sure to wear appropriate personal protective equipment such as gloves, safety glasses and protective clothing during use.

2. Dissolving polyacrylamide: Polyacrylamide is mostly in powder or granular form and needs to be dissolved in water. Slowly add the required amount of polyacrylamide to clean water and stir while adding until it is completely dissolved. Usually, a polyacrylamide solution with a concentration of 0.1% to 1% is used.

3. Stirring and mixing: The dissolved polyacrylamide solution needs to be fully stirred and mixed to ensure uniform dispersion. A stirrer, stirring rod or other appropriate equipment can be used for stirring.

4. Application areas:

- Water treatment: Polyacrylamide is often used in the process of solid-liquid separation to treat wastewater, sewage, industrial emissions, etc. It can help suspended matter settle and purify water quality.


- Soil improvement: Polyacrylamide can be used to improve soil structure, reduce soil erosion, increase soil water retention capacity and fertilizer utilization. In farmland, polyacrylamide solution can be sprayed or spread on the soil surface.

- Oil extraction: Polyacrylamide can be used as an auxiliary agent in oil extraction to increase the production capacity of oil wells and improve oil recovery efficiency.

Papermaking: Polyacrylamide can be used as a wetting agent and strengthening agent in the papermaking process to improve the dispersibility and mechanical strength of pulp.

5. Precautions: When using polyacrylamide, please pay attention to the following points:

- Follow the recommended dosage of the product supplier and avoid excessive use.

- If discomfort or harmful reactions occur when using polyacrylamide solution, stop using it immediately and seek professional medical advice.

- It is forbidden to discharge polyacrylamide solution directly into natural water bodies to avoid pollution to the environment.

Please note that the above is an overview of the general use of polyacrylamide. In specific application areas, there may be more specific operating guidelines and precautions. It is recommended to refer to relevant literature and professional opinions before use.
