【Selection of mineral processing sewage treatment agent】
Anionic polyacrylamide or nonionic polyacrylamide products are generally used for the precipitation of mineral processing wastewater.
According to the selected mineral processing water treatment process and the nature of the mineral washing water, the product model and dosage are determined through tests.
The appropriate use of polyacrylamide in mineral processing wastewater not only improves the flocculation effect and effectively treats the ore-washing mud wastewater, but also plays an important role in ensuring the indicators of mineral processing products, improving work efficiency, and reducing costs.
POLYMERSCO can provide a free selection to select polyacrylamide products with better results and less dosage for you.
【Precautions for use】
1. When using, the operation of effectively dispersing this product in water is extremely important, otherwise, it will cause the dispersant to clump and produce “fish eyes”, and the dissolution time will increase.
2. The use of warm water can speed up the dissolution rate, but the temperature is too high, which will cause the thermal degradation of the polymer chain and the viscosity will be affected. Generally, the water temperature cannot exceed 50℃.
3. Stirring is used to help dissolve, but stirring too vigorously will cause the long chain of dispersants to break and degrade. The agitator is best to use a ship-type propulsion type.
4. The storage time of the aqueous solution should not exceed 48 hours, otherwise it will easily cause the viscosity to decrease and affect the use effect.
【Storage method】
1. Polyacrylamide is stored in a cool, dry, and ventilated environment.
2. Polyacrylamide storage cannot be stacked directly on the ground, it is best to store it on the pallet to prevent it from absorbing moisture and agglomeration.
3. The number of stacked layers of polyacrylamide storage should not be too high, and the number of stacked layers generally does not exceed ten layers.
4. Unused polyacrylamide must be sealed in packaging bags and must not be exposed to air, otherwise it will easily clump.
5. Polyacrylamide must follow the principle of first storage and first use.
