Selecting the Appropriate Polyacrylamide Type: Choose the appropriate polyacrylamide type based on soil properties and application scenario. For example, cationic polyacrylamide is suitable for anionic soils, and anionic polyacrylamide is suitable for cationic soils.
Determining the Dosage: Determine the appropriate dosage based on soil properties, application scenario, and the type of polyacrylamide. Generally, the addition amount of polyacrylamide is between 0.1% and 0.5%, but the specific dosage needs to be determined through experimentation based on actual conditions.
Preparing the Solution: Mix polyacrylamide and water in a certain proportion and stir evenly to prepare a polyacrylamide solution of appropriate concentration. Note that high-speed stirring should be avoided during solution preparation to prevent the formation of air bubbles, which will affect the effectiveness of the polyacrylamide.
Application Method: Spray the polyacrylamide solution evenly onto the soil surface that needs stabilization, ensuring that the polyacrylamide solution fully penetrates the soil. After application, cover with a thin film or other protective material to reduce water evaporation and the impact of windblown soil.
