#poly acrylamide

Due to monetary and technological reasons, polymer flooding is still the most potential and valuable three-recovery technology within the present day and future. The relative molecular weight is set 25 million, and the excessive molecular weight polyacrylamide with low water-soluble substance is the primary range for oil displacement at present.

The polymer may be synthesized as an easy linear chain or as a cross-linked structure. PAM ultimately increases the viscosity of water particles and forces the flocculation in all the particles present in liquid water.

The cross-related polymer can take in and preserve extremely big quantities of water because the amide organizations form sturdy hydrogen bonds with water molecules. The hydrated PAM is a soft gel that is utilized in gel electrophoresis and as an excellent water-soaking up polymer (SAP's).

Even even though those polymers are referred to as polyacrylamide, they're often copolymers of acrylamide and one or more other monomers. The most vital co-monomer is acrylic acid or sodium acrylate.

Poly(acrylamide-co-acrylic acid) and its sodium salt are anionic polymers which can be more powerful as a flocculant and water absorber.

Poly Acrylamide Applications

PAA co-acrylic acid and all sodium salts (APAM) within are commonly used as a thickening agent that not only binds but absorbs soil conditioner and acts as a filtering aid in the flocculating agent.

One of its largest makes use of is wastewater treatment. When introduced to wastewater, it reasons suspended particles to the mixture and to precipitate. In municipal and business wastewater treatment it is able to be utilized in all liquid-strong separation approaches including number one sewage remedy. 

PAMs are commonly used to treat water from mineral mining resources. Another commonplace use is oil extraction and recuperation. When water is injected into the well, PAM assists in pushing oil locked in reservoirs closer to the pump by growing the viscosity of the injected water.

Cationic polyacrylamides (CPAM) are used for emulsion breaking, and for selling filtration and sludge dewatering.

The primary use is wastewater treatment. As a primary natural coagulant, it neutralizes negatively charged colloidal debris and hence induces flocculation and sedimentation which reduces sludge extent. 

A different low volume but essential use of anionic and cationic polyacrylamides is for the gel electrophoresis that is used for macromolecule separation. When an electric area is applied throughout a PAM gel, the (negatively) charged proteins or nucleic acids migrate throughout the gel away toward the nice electrode.

Since the mobility relies upon on the rate and size of the molecules, each molecule species migrates differently via the gel matrix.

What is Cationic Poly Acrylamide

CPAM | Cationic | Poly | Acrylamide | Poly Acrylamide |  

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, paper making, 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.

Description 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 waste waters 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.
