How can I quickly dissolve polyacrylamide?

Thickening generally uses anionic polyacrylamide, abbreviation: APAM.

APAM products are available in dry powder type and emulsion type, the dissolution time of dry powder type is about 30 minutes (proportional aqueous solution), and the dissolution speed of emulsion type is fast.

If you don't want to increase the cost, water is a good solvent. I'm talking about the fastest speed.

If you use a large amount in production, it is recommended that you prepare 2-3 dissolving tanks, which is also a common method in large factories, and the size of the dissolving tank depends on the amount used.

If you use a small amount, you can use emulsion APAM. Dissolves in minutes.

If you use a small amount, you can go to the market and buy some dissolved ones. Convenient.

I also think that adding some organic solvents can make the solubility greater.

There is another piece of information:

Dissolution and use of polyacrylamide (PAM).

1) PAM is an organic polymer compound, which can be divided into anionic, cationic and non-ionic, white powder or granules, soluble in water, but the dissolution rate is very slow;

2) The anionic type is generally used as a flocculant for wastewater treatment, and the cationic type is generally used for sludge dewatering;

3) When used as a flocculant, the dosage is generally 1-2ppm, that is, the dosage is about 1-2g per 1 ton of wastewater treated;

4) When using, the anionic type is generally prepared into an aqueous solution, and the cationic type can be prepared;

5) When preparing the solution, water should be added to the dissolving tank first, then the mixer should be turned on, and then the PAM should be added slowly along the whirlpool.

6) After adding PAM, you should generally continue to stir for more than 30min to ensure that it is fully dissolved;

7) The dissolved PAM should be used as soon as possible, the anionic type should generally not exceed 36h, the cationic type is easy to hydrolyze after dissolving, and should be used within 24h.

PS: It may be better to add warm water not exceeding 60 degrees to dissolve.

To dissolve polyacrylamide, pour it slowly into the water. Don't fall down all at once, it's easy to clump.

Summary. Pro: In general, polyacrylamide is quite soluble in water, so it usually doesn't require too many methods to promote its dissolution. Here are some ways you can speed up the dissolution of polyacrylamide:

Increase mixing time and speed: Use a blender to slowly add polyacrylamide powder to the stirring water and gradually increase the mixing time and speed, which can help dissolve it quickly. Heating water temperature:

Heat the water to 50-60 and polyacrylamide dissolves more easily. However, please note that if the water temperature is too high, the polyacrylamide molecular chain will be broken and degraded, which will affect the polymer properties. Powder is thrown directly into the water:

Rapid dissolution can also be achieved by pouring polyacrylamide powder directly into the water and then mixing it quickly with a stirrer or other method. Care needs to be taken to avoid large polymer curds in this method.

Powder directly into water: Polyacrylamide powder is put directly into water, and then quickly mixed with a stirrer or other methods, which can also achieve the effect of rapid dissolution.

In this method, care needs to be taken to avoid the polymer curds of the Daxiangshan block.

What additives can be added to help solubilization?

Common co-solvents include organic solvents such as ethyl alcohol and acetone, inorganic salts such as sodium chloride, sodium carbonate and sodium sulfate, and surfactants such as sodium alkylbenzene sulfonate.

Summary. When dissolving, the speed of the stirring motor is controlled at about 100 revolutions per minute. If the temperature is cold, increase the water temperature a little.

Hello, pro-polyacrylamide, mainly solid granular, to increase the dissolution rate of PAM, you can refer to the following suggestions: 1. Increase the temperature of the mixture, but it is not clear that it should be higher than 50 degrees. 2. Pay attention to the stirring speed, and the elimination state should not be too much.

3. Adjust the pH reasonably, the solution is weakly alkaline, and it should not exceed the addition of some agents, such as surfactants, urea, etc.

When dissolving, the speed of the stirring motor is controlled at about 100 revolutions per minute. If the temperature is cold, increase the water temperature a little.

Polyacrylamide is a polymer compound that forms a network structure that makes it difficult for water molecules to pass through, resulting in high viscosity properties. However, long-term storage or exposure to the sun will lead to the breakage or degradation of the polyacrylamide molecular chain, which will reduce the viscosity of the solution.

In order to avoid the loss of viscosity of the polyacrylamide solution, the following points need to be noted:

Storage temperature: Storing the polyacrylamide solution in a low temperature environment can effectively delay the degradation and breakage of its molecular chains, thereby maintaining its high viscosity characteristics.

Avoid sun exposure: Poly-pyrone-fueled acrylamide molecular chains are susceptible to damage from UV rays, so they need to be avoided from exposure to sunlight.

Avoid mechanical shear: Polyacrylamide molecular chains are susceptible to mechanical shear and therefore need to avoid excessive shear forces in operations such as agitation or pumping.

In short, in order to maintain the viscosity of polyacrylamide solution, it is necessary to pay attention to protection in terms of storage bucket and use to avoid the breakage and degradation of its molecular chains.

Summary. Generally speaking, the following principles should be followed:

1. Granular polyacrylamide flocculant cannot be directly added to sewage. It must be dissolved in water before use, and its aqueous solution must be used to treat sewage.

2. The water in which the granular polymer is dissolved should be clean (such as tap water), not sewage. Water at room temperature is sufficient, and generally does not need to be heated. Water temperature below 5 is very slow to dissolve.

The dissolution speed is accelerated when the water temperature increases, but more than 40 will accelerate the degradation of the polymer and affect the use effect. In general, tap water is suitable for the preparation of polymer solutions. Water with strong acid, alkali and high salt content is not suitable for preparation.

3. For the selection of the concentration of polymer solution, Lebang Company suggests that 1g-3g polymer powder be added to 1 liter of water (consult the technical department of Lebang Company for details).

Poly two distortion gum is a kind of polymer substance, with good solubility, the rubber can be dissolved in water, and the solubility is very high. After drying, the molecular structure of poly and glue changes next to the beam, but it can still be dissolved in water, but the solubility will be reduced.

Therefore, the poly two suspicions can still be dissolved in water after drying.

I'm still a little confused, can you be more detailed?

Yes, after the glue is dissolved in water and dried, the water molecules are just pumped out of the colloid, and the structure of the colloid does not change, but it becomes harder, so it can be dissolved in water again. Reason: The structure of the colloid has not changed, but has become harder.

Solution: Put the colloid in water, heat and stir to re-dissolve the colloid in the water. Personal Tips:

When dissolving the colloid, it is necessary to pay attention to controlling the temperature so as not to change the colloid and affect the dissolution effect. Related knowledge: Colloid is a suspension composed of one or more molecules, which has special physical properties and can be dissolved in water, but when the water molecules are withdrawn from the colloid, the colloid will become harder, but it can still be dissolved in water.

Related extension: Polyacrylamide is a linear polymer compound with many polar groups on its molecular chain, which can form hydrogen bonds with water molecules, so it can be dissolved in water. Polyvinyl alcohol is also a linear polymer compound, but its molecular chain has fewer OH groups, so its solubility in water is lower than that of polyacrylamide.

<>Although polyacrylamide and polyvinyl alcohol can be dissolved in water, due to their different chemical structures and physical properties, they often precipitate and coagulate each other in aqueous solution, and it is difficult to achieve effective mixing effect. If they need to be mixed, special methods such as heating, ultrasonication, etc., are usually required to facilitate their mixing and dissolution. <>

Not heating is one. Is there any other good way?

Ultrasound treatment

Can you explain the ultrasound?

The polymer is placed in water and repeated with an ultrasonic oscillator to produce an external force on the polymer molecules, thereby accelerating their molecular motion, expanding the front dispersion and dissolving the polymer.
