Description

Product performance

Polyacrylamide (cpolyacrylamids) referred to as PAM, is a linear polymer, is one of the most widely used varieties of water-soluble homomolecular compounds, polyacrylamide and its derivatives can be used as effective flocculants, Thickeners, paper additives, and liquid drag reducers are widely used in water treatment, papermaking, petroleum, coal, mining and metallurgy, geology, textiles, construction and other industrial sectors.

This product is an organic polymer flocculant, and its models are divided into anionic, cationic and nonionic. It has strong bridging and adsorption properties in water, which can quickly change small flocs into coarse flocs, reduce the water content of flocs, and accelerate the settlement of flocs; it has strong adaptability to the pH value, turbidity and temperature of raw water ; At the same time, it has excellent decolorization and heavy metal removal effects.

PAM is used for sewage treatment. It has high removal efficiency of organic matter in water, less dosage, fast settling speed and low cost of water production. It is a product that cannot be replaced by other flocculants.


Scope of use

This product is used for sewage treatment of petroleum, metallurgy, mineral processing, papermaking, textile, sugar, stone cutting, chemical industry, medicine, electroplating and so on. Pay attention to moisture and sun protection during transportation and storage. Add water to dissolve this product as needed to form an aqueous solution, and put it into water with a metering pump. Combined with PAC, PFS and other inorganic flocculants, the effect is better.

How to use

The dissolution method of powdered polyacrylamide is very different from that of inorganic small molecule iron salts and aluminum salts. Generally speaking, the following principles should be followed:

1) The powdered polyacrylamide flocculant cannot be directly added to the sewage, it must be dissolved in water before use, and then its aqueous solution is added to the sewage according to a certain dosage to treat the sewage.

2) The water used to dissolve powdered polymers should be clean water (such as tap water), not sewage, and normal temperature water is sufficient, usually without heating. If the water temperature is too high, the polymer will be thermally degraded, which will affect the use effect. Generally, the pH value of tap water meets the requirements for preparing polymer solutions. Strongly acidic or alkaline water is not suitable for preparing aqueous solutions of polymers.   

3) The concentration of the polymer is recommended to be 1‰~3‰, that is, add 1~3g of polymer powder to one liter of water.

The selection of concentration should consider the following factors:

If the container for preparing the polymer solution is small and the daily medicinal dosage is large, it is recommended to prepare a slightly higher concentration: such as 3‰. When the molecular weight of the polymer to be prepared is very high, it is recommended to prepare a slightly thinner concentration: such as 1‰. After the polymer is added to the sewage, if the dispersion state is not very good due to equipment reasons, it is recommended to prepare a slightly thinner concentration. In short, if the polymer concentration is too high, the load on the agitator motor will be too large, and the dispersion of the polymer solution into the sewage will not be good, which will affect the use effect. A thinner mixture will help improve the use effect.

4) Do not transfer the prepared solution through a centrifugal pump to avoid shear degradation of the polymer caused by high-speed rotating blades. The specific method of preparation is as follows:

★Add a certain amount of water into the container (such as a laboratory beaker or a factory preparation tank), calculate and weigh the required amount of polymer according to the amount of water.

★Turn on the agitator, stir the clean water out of the vortex, and the linear speed of the end of the agitator blade should not exceed 8 m/s, so as not to cause polymer degradation.

★At the same time, the stirring speed should not be too slow, so as to prevent the polymer particles from sinking and agglomerating in water.

★Slowly sprinkle the polymer into the vortex of water, and pay attention to avoid the polymer particles sticking to each other and agglomerating after entering the water. Then stir for a period of time to fully dissolve the polymer particles, and finally become a uniform, transparent and viscous solution.

The length of stirring time can be determined as follows:

★When the water temperature is high in summer, the anionic and cationic polymers need to be stirred for about 1 hour, and the non-ionic polymers need to be stirred for about 2 hours.

★When the water temperature is low in winter, the anionic and cationic polymers need to be stirred for about 1.5 hours, and the non-ionic polymers need to be stirred for about 3 hours.

Uneven or insufficient dissolution will affect the effect of use.

Iron ions are catalysts that cause the chemical degradation of polyacrylamide. Therefore, when preparing, transferring, and storing polyacrylamide solutions, avoid contacting the solution with iron ions. Equipment for preparing polymer solutions is preferably constructed of materials such as stainless steel, fiberglass, or plastic-lined carbon steel.
