Some experiences in the use of cationic polyacrylamide
I. Overview of cationic polyacrylamide
Cationic polyacrylamide is a white powder granule with strong flocculation effect, so it is widely used in water treatment and metallurgy, papermaking, petroleum, chemical, textile, mineral processing and other fields. The cationic high-molecular flocculant is a linear polymer compound dissolved in water. The molecular weight is between 600 and 18 million. It can be dissolved in methanol and ethanol, and is insoluble in organic solvents such as ketones, esters and hydrocarbons. It is positive in the acidic or alkaline medium, which effectively flocculates and precipitates the sewage with suspended charges in the sewage.
Second, the experience of cationic polyacrylamide in use
The following are some of the considerations that we have summarized when we use cationic polyacrylamide.
1. Powdered cationic polyacrylamide must be dissolved before use. The dissolved aqueous solution will work better.
2. When dissolving, it is preferred to add the cationic polyacrylamide while stirring the aqueous solution. Remember: cationic polyacrylamide is added little by little. Also, keep stirring continuously for at least 30 minutes to ensure adequate dissolution.
3. The amount of cationic polyacrylamide. Typically, 1-2 g or 3-5 g of cationic polyacrylamide is added per ton of water.
4. When using, also use while stirring. This involves the installation location of the device, and you can arrange it in advance when you use it.
5. The water that dissolves the granular polymer should be clean (such as tap water) and not sewage. Water at room temperature can be used, generally no heating is required. Water temperatures below 5 ° C are very slow to dissolve. The water temperature increases the dissolution rate, but above 40 °C, the polymer will accelerate degradation and affect the use effect. Generally tap water is suitable for formulating polymer solutions. Strong acid, strong base, high salt water is not suitable for formulation.
6, the amount of use. The normal dosage is: 0.1% - 0.3%, that is, 1 g - 3 g of the preparation solution is added to 1 liter of water.
7. Do not allow cationic polyacrylamide to contact with iron metal, otherwise cationic polyacrylamide will fail.
