The Best Guide of Polyacrylamide in 2020.
Many people find polyacrylamide more expensive than other water purifiers when they purchase and learn about it.Especially the cationic type. Why is the price of polyacrylamide more expensive? Is it in our economic interest to use polyacrylamide as a water purifier?
In fact, although the price of polyacrylamide is relatively high, its dosage is much lower than other water purification agents when treating the same volume of sewage. Such as ferrous sulfate, polyaluminum chloride, alum and so on.Therefore,viscosifier, it is in our economic interest to treat the same volume of sewage with polyacrylamide.
Here is to introduce the excellent performance of polyacrylamide.
Flocculation: it can neutralize the suspended substances through electricity, bridge adsorption and flocculation.
Adhesion: it can be bonded by mechanical, physical and chemical actions.
Resistance reduction: it can effectively reduce the friction resistance of the fluid. Adding a small amount of PAM in water can reduce the resistance by 50-80%.
Thickening property: it has thickening effect under neutral and acid conditions. When the pH value is above 10, PAM is easy to hydrolyze. The thickening will be more obvious when the structure is semi reticular.
What are the functions and characteristics of polyacrylamide drilling fluids?
It plays an important role in the process of oil recovery.
1.Good water solubility. Polyacrylamide is soluble in water, mostly in the form of aqueous solutions, and a hydrogen bond is formed between the water molecule and the polar sidebase of polyacrylamide.Polyacrylamide can be dissolved in water in various percentages.
2.Rheology. Rheological property is the property of flow deformation of object under the action of external force. From the view of apparent viscosity and shear force, the apparent viscosity of polyacrylamide will decrease when the shear force increases, but when the shear force is cancelled, the apparent viscosity will gradually recover with the increase of time.
3.Increase viscosity. Viscosity enhancement is the effect of polyacrylamide on the apparent viscosity of aqueous solution or aqueous dispersion.
The viscosity of water phase is increased by its own viscosity.
Polyacrylamide interacts with dispersed phase or compound in water. The effect is much higher than the viscosity of polymer itself.
4.Dispersion. Polyacrylamide contains hydrophilic groups. And theres a skeleton. The surface has certain activity. To a certain extent, it can reduce the surface tension of water. This helps to wet the solid with water. The water colloid complex can be adsorbed on the colloidal particles to form a shell. Free from flocculation caused by electrolytes. The dispersion system is stable.
5.Flocculation. The polar groups in polyacrylamide can adsorb suspended solids in water. It can bridge the ions and form large agglomerates.
How to choose a real polyacrylamide manufacturer
Up to now, polyacrylamide manufacturers are as many as stars in the sky. Customers always want to choose the manufacturers with good quality.However, it is still very difficult to do so without any experience and summary.
1.Visit the polyacrylamide manufacturer. Field investigation can verify whether a manufacturer has enough supply capacity. See if it is under the banner of “manufacturer”, and then does not have its own factory.
2.Let the polyacrylamide manufacturer send samples. After receiving the sample, do your own test to judge. If it is a real manufacturer, the product effect will be very good.
3.Judging from the price. If the price of this manufacturers products is too much lower than the market price. There may be something wrong with the product. It is also possible that the reputation of this manufacturer is not good. So you can make a judgment.
