Because the Anionic Polyacrylamide (Anionic Flocculant) has the outstanding characteristic in the thickening performance, normally it could be used as the thickening agent in various industries. The Anionic Polyacrylamide (Anionic Flocculant) is suitable in the treatment of the weakly acidic to alkaline waste water in the industries such as the chemical industry, the foodstuff industry, the dyeing processing, the fiber production and the metal processing etc.

Currently there are many different flocculants in the market and have been widely used, they have been existing in a broad range of applications. The Anionic Flocculant (Anionic Polyacrylamide) is normally used as the thickening agent, which is just one of its numerous functions in the practical applications. As the thickening agent, the remarkable advantages of the anionic flocculant are roughly as below:

Feature One:
When the Anionic Flocculant is dissolving in the water, it will start to dissolve rapidly immediately when it is just been put into the water, usually it will take about one hour to get the Anionic Flocculant been dissolved completely, and the solution will become a kind of viscous and transparent solution without undissolved particles or masses, thus, this anioinic flocculant solution get the thickening function.

Feature Two:
The anioinic flocculant which is working as the thickening agent is fairly salt resistant, this is a unique feature which the other similar thickening agents can not get achieved.

Feature Three:
There is a big advantage for the Polyacrylamide being used as the thickening agent, that is the Polyacrylamide itself is of transparent material, it will not change the original color of the raw materials.

Feature Four:
The anionic flocculant which is working as the thickening agent has very excellent water solubility. The anionic flocculant is a type of powder which has the very high water solubility, the undissolved matter is very less after it is dissolved in the water. The thickening effect of the anionic flocculant is always very ideal.

As the efficient thickening agent, the anionic flocculant could be used in the construction glue, it could be used as the thickening agent in the incense making process and in the cosmetics etc. Under the normal circumstances, the anionic flocculant can meet all of the thickening requirements and the needs for different industries.

The anionic flocculant is widely used in the construction glue as the thickening agent. The ordinary chemical materials for the construction glue are: the polyvinyl alcohol, the acrylamide (AM) and the polyacrylamide (PAM) etc. There are many different common construction glues such as #107, #108, #801 and #901 etc, the production technology for each construction glue is very similar. The introduction of a small amount of the polyacrylamide in the glue can help to get the good viscosity, the good lubrication degree and the water retention capability.

The anionic flocculant can also be used in the paint production. The anionic flocculant used as the paint thickening agent has the special performance, which can change the fluid dynamics properties of the paint. It can help to increase the viscosity between the molecules, and to make the paint system maintain the uniform and stable state of suspension, or the opaque stand, or the gel formation. Generally speaking, the spraying paint needs more smooth liquidity, in order to form the long wave effect, as it is called, which can make the coating be more uniform. Therefore, the spraying paint needs to add a kind of low viscosity thinner or to add a type of leveling promoter to meet this painting requirement, the introduction of the additives can make the paint more symmetrical and more convenient to use, but at the same time, will not change the original properties of the paint itself.

The dosage of the aninoic flocculant in different applications as the thickening agent

1.In the kitchen detergent, the laundry detergent, the washing liquid and the other detergent, the conventional proportion is 1 % ~ 1.5%.
2.In the mortar for the water conservation, the conventional dosage is 4 kg to 8 kg per metric ton.
3. For the putty powder tackifier and water retention, the conventional dosage is 5 kg to 10 kg per metric ton.
4. In the construction glue, the conventional dosage is 3 kg to 10 kg per metric ton.
5. For the thickening, the viscosity promotion and the water retention of the paint, the conventional dosage is 3 kg to 10 kg per metric ton.

Using method of the Polyacrylamide

Before using, the solid polyacrylamide should be dissolved into the solution with the concentration at 0.1% to 0.5%, in order to speed up the effectiveness of the polyacrylamide. In the dissolution process, you need to stir the water in the dissolving tank while paying strict attention to the adding of the solids, that is to make sure the uniform spreading of the polyacrylamide into the water, without generating the solid polyacrylamide blocks in the water.

Since in the dissolving process, the long time and severe stirring may damage the performance of the polyacrylamide, the recommended stirring speed of the mixer to dissolve the polyacrylamide should be around 20 rpm to 200 rpm.

Since if the polyacrylamide solution stands for long time, its performance will be reduced gradually based on the water quality situation, the aqueous solution should be used in three days after it is modulated.
