Anionic Polyacrylamide


Mã sản Phẩm: A-PAM


Anionic polyacrylamide (APAM) is a water soluble polymer. Because the polar groups on the molecular chain containing a certain amount, it can through the adsorption of solid particles suspended in water, bridging between particles or through the charge and make the particle formation of large flocs condensation. So, it can accelerate the settlement of particles in suspension, have obvious to speed up the solution to clarify, promote filtering and other effects. Mainly used for various industrial wastewater flocculation sedimentation, sedimentation and clarification treatment, such as iron and steel plant wastewater, electroplating wastewater, wastewater metallurgy, coal washing wastewater treatment, sludge dewatering. Can also be used to clarify and drinking water purification treatment.

Anionic polyacrylamide product features

1. Good water solubility, can be completely dissolved in water.

2. Add a small amount of the anionic polyacrylamide products, can be greatly the flocculation effect. The general need to add 0.01~10ppm (0.01~10g/m3), can give full play to the role of.

3. At the same time, the use of anionic polyacrylamide products and inorganic flocculant (ferric sulfate, polyaluminum chloride, iron etc.), but showed a greater effect.

Anionic polyacrylamide function

1. Clarification and purification effect;

2. To promote the role of settlement;

3. Filtering effect;

4.The thickening effect and other effects. In wastewater treatment, sludge concentration and dewatering, mineral processing, coal washing, papermaking etc., can fully meet the requirements of various fields.

The using method of anionic polyacrylamide

1. When in use, with 0.1% concentration in the aqueous solution, to use neuter excluding salts sundry water is appropriate.

2. Dissolved, the anionic polyacrylamide product evenly into the mixing water, stirring speed control in 100~300rpm. Appropriate heating (< 60 ° C), can accelerate the dissolution of.

3. Adjust the solution pH, the anionic polyacrylamide products, give full play to the role of (through the test to select the best pH value and the series of products are used.)

4. Adding anionic polyacrylamide product solution, should be mixed with acceleration and disposing liquid, appear floc, slow stirring speed, growth and accelerated subsidence Eli floc.


1. The operator should wear protective equipment, after contact with skin, wash with water.

2. The use of the site, often in water to rinse, prevent slippery fall injury.

3. Anionic polyacrylamide products should be sealed storage in a cool dry place.

Application of anionic polyacrylamide

1. Used in textile, printing and dyeing industry. Polyacrylamide as fabric treatment of sizing agent, finishing agent, and a protective layer can generate smooth, wrinkle, anti - mildew. With its strong absorption characteristics, can break a rate reduction spinning at. Polyacrylamide is used as finishing agent can prevent the electrostatic and flame retardant fabric. Used for printing and dyeing auxiliaries, PAM can make the product attachment fastness, bright degree is high, can also be used as a non-silicon polymer stabilizer bleaching.

2. Mainly used as a flocculant: for suspended particles, coarse, high concentration, particle with positive charge, water pH value is neutral or alkaline water, due to the solid particle anionic polyacrylamide molecular chain containing a certain amount of polar groups can adsorb the suspended, the interparticle bridging into large flocs. Thus it accelerated in the settlement of particles suspension, have obvious to speed up the solution to clarify, promote filtering and other effects. The products are widely used in the treatment of wastewater, waste chemical industry, municipal sewage treatment. Tap water industry, high turbidity water purification, coal washing, dressing, metallurgy, iron and steel, zinc, aluminum industry, electronic industry water treatment.

3. Used in the oil industry, oil, drilling mud, waste mud treatment, prevent water channeling, reduce friction, enhanced oil recovery, extraction of three times the widely used.

4. For the paper industry, one is to improve the packing, pigmentretention rate. In order to reduce the loss of raw materials and the pollution of the environment; two is to improve the strength of paper (including dry strength and wet strength), in addition, you can also use the PAM to improve the paper tearing-resistance sex and porous, to improve vision and printing performance, also used in food and tea packaging paper.

5. Other industry, food industry, cane sugar, beet sugar production in sugar cane juice clarification floatationextraction. Enzyme fermentation liquid clarification industry, also used in the recovery of protein feed, stable quality, good performance, recovery of the protein powder on chicken survival without adverse effect rate and weight gain, egg, synthetic resin coating, construction of grouting material and water plugging, building materials industry, improve the quality of cement, construction adhesives, caulking and repair water shutoff agent, soil improvement, electroplating, printing and dyeing industries.
