Cationic Poly Acrylamide (CPAM)

Cationic-Poly-Acrylamide.png

Cationic Poly Acrylamide(CPAM) is a linear polymer compound. Because it has a variety of active groups, it can be affinity with many substances and form hydrogen bonds. Mainly flocculates negatively charged colloids with the functions of removing turbidity, decolorization, adsorption, adhesion and other functions. It is suitable for organic colloid content in industries such as dyeing, papermaking, food, construction, metallurgy, mineral processing, pulverized coal, oil fields, aquatic products processing and fermentation. Higher wastewater treatment is particularly suitable for the dewatering of municipal sewage, municipal sludge, paper sludge and other industrial sludge.

Specifications:
※ Appearance: White powder or granular appearance

※ Solid content: ≥90%

※ Molecular weight: 800-1200 million

※ Insoluble matter: ≤0.5%

※ Residual unit: ≤0.05%

※ Cation degree: 10-90 %

※ Dissolution time: ≤60 minutes

The Scope of Application:
1)
 For sludge dewatering depending on the sludge properties, the corresponding grades of CPAM products can be used. The sludge can be effectively dewatered before the sludge enters the pressure filtration. When the sludge is dewatered, large flocs and non-sticky filter cloths are produced. Scattered, thick mud cake flow, high dewatering efficiency, mud cake moisture content below 80%.

2) For the treatment of domestic sewage and organic waste water, cationic poly acrylamide products are all positive in compatibility or alkaline medium, so that the flotation and sedimentation of sewage with suspended particles in the sewage with negative charge is very effective. Such as the production of grain alcohol wastewater, papermaking wastewater, municipal wastewater treatment plant wastewater, brewery wastewater, monosodium glutamate wastewater, sugar wastewater, organic high wastewater, feed wastewater, textile printing and dyeing wastewater, using cationic poly acrylamide than anion, Non-ionic poly acrylamides or inorganic salts are several or more times more effective because such wastewaters are generally negatively charged.

3) The flocculating agent for tap water with river water as the source of water is less in amount, effective, and low in cost, especially in combination with inorganic flocculants. It will become the tap water for the Yangtze, Yellow and other river basins. The plant’s efficient flocculant.

Usage
1).Through a small test to determine the best model, and the product’s optimal dosage.

2). The product is formulated as an aqueous solution with a concentration of 0.2% (referring to the solid content), preferably neutral water without salt.

3). Dissolved water, the product evenly sprinkled into the stirring water, appropriate heating (<60 °C) can be accelerated into a solution (stirring time is about 40 minutes).

4). Solid products should not be sprinkled on the floor to prevent the product from becoming slippery after absorbing moisture.

5). The preparation of PAM aqueous solution should be carried out in enamel, galvanized, aluminium or plastic barrels. It cannot be prepared and stored in iron containers.

6). When dissolving, care should be taken to add the product evenly and gradually to the dissolver with stirring and heating measures. The solidification should be avoided. The solution should be prepared at a suitable temperature, and mechanical shearing should be avoided. Mixer 60-200 rev / min, otherwise it will lead to polymer degradation, affecting the use of effects.

7). The PAM solution should be ready for use. When the solution is left for a long time, its performance will gradually decrease depending on the water quality.

8). After adding an aqueous flocculant solution to the suspension, if the stirring is vigorously performed for a long time, the formed flocks will be destroyed.

Packaging, Storage and Handling and Precautions:
Solid products are packed in paper bags, lined with plastic bags, 25kg per bag, and can also be packaged according to customer requirements.

This product has hygroscopicity, should be sealed and stored in a cool dry place, the temperature is lower than 35 °C, the effective storage period is 2 years.
