Anionic polyacrylamide (Praestol 2515) can be replaced by CHINAFLOC A2520

 

PRAESTOL 2515 is used mainly for flocculation of mineral and hydroxide type solid particles and colloids, preferably for clarification of washing

 water in the treatment of mining raw materials. It also used for the treatment of surface and ground water, and all types of waste water, after 

preliminary treatment with hydroxide forming substances.

 

Anionic polyacrylamide (APAM) is a water-soluble polymer, mainly used for all kinds of industrial wastewater flocculation sedimentation, precipitation clarification treatment, such as steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other sewage treatment, sludge dehydration. It can also be used for drinking water clarification and purification treatment. Because of anionic polyacrylamide molecular chain contains a certain number of polar groups, it can through the adsorption of solid particles suspended in water, make the bridge between particles or by charge neutralization particles condensed to form large flocculate, so it can accelerate suspension of particles sedimentation, have very significant to speed up the solution to clarify, to promote such as filtering effect.

[Product features] :

 

1. Anionic polyacrylamide is water-soluble and can be completely dissolved in cold water.

 

2, add a small amount of anionic polyacrylamide, can be subjected to a great flocculation effect. Generally, only 0.01~10ppm (0.01~10g/m3) is needed to give full play to the effect.

 

3, the use of anionic polyacrylamide and inorganic flocculant (polyferric sulfate, polyaluminum chloride, iron salt, etc.), can show a greater effect.

 

[Usage] :

 

1, when used, anionic polyacrylamide with 0.1% concentration of water solution, to use neutral non-salt debris water is appropriate.

 

2. When dissolving, anionic polyacrylamide is evenly scattered into the stirred water, and the stirring speed is controlled at 100~300rpm. Proper heating (< 60°C) can accelerate dissolution.

 

3, adjust the PH value of the solution to be treated, so that anionic polyacrylamide fully play a role (through the test to select the best PH value and anionic polyacrylamide dosage.)

 

4, adding anionic polyacrylamide solution, should be accelerated with the mixing of the treated liquid, the occurrence of flocculation, slow down the stirring speed, to facilitate the growth of flocculation and accelerated settlement.

 

[Scope of application] :

 

1. Anionic polyacrylamide as fabric treatment sizing agent, finishing agent, and can generate a soft, wrinkle resistant, mold resistant protective layer. With its high moisture absorption, it can reduce the breaking tension of spinning yarn. Polyacrylamide as post-treatment agent can prevent static electricity and flame retardant fabric. Used as printing and dyeing auxiliaries, polyacrylamide can make the product adhesion fastness, high brightness, but also as a bleaching non - silicon polymer stabilizer.

 

2, anionic polyacrylamide used as flocculant: for suspended particles, coarse, high concentration, particles with positive charge, water PH value is neutral or alkaline sewage, due to anionic polyacrylamide molecular chain contains a certain amount of polar base can absorb suspended solid particles in water, so that the formation of large flocculant bridging between particles. Therefore, it accelerates the sedimentation of particles in suspension, accelerates the clarification of solution and promotes filtration. The product is widely used in chemical industry waste water, waste liquid treatment, municipal sewage treatment. Tap water industry, high turbidity water purification, sedimentation, coal washing, mineral processing, metallurgy, iron and steel industry, zinc, aluminum processing industry, electronic industry and other water treatment.

 

3, anionic polyacrylamide used in the petroleum industry, oil recovery, drilling mud, waste mud treatment, prevent water channel, reduce friction, enhance oil recovery, three oil recovery has been widely used.

 

4, anionic polyacrylamide used in paper industry, one is to improve the retention rate of filler, pigment, etc. To reduce the loss of raw materials and environmental pollution; Two is to improve the strength of the paper (including dry strength and wet strength), in addition, the use of PAM can also improve the tear resistance and porosity of the paper, to improve the visual and printing performance, but also used in food and tea wrapping paper.

 

5, anionic polyacrylamide in other industries, such as the food industry, used in sugar cane, sugar beet sugar production cane juice clarification and syrup phosphorus float extraction. Enzyme preparation fermented liquid flocculation clarifying industry, also used in feed protein recovery, stable quality, good performance, recovery of protein powder to chickens and raising the survival rate of weight gain, no adverse effects of egg production, synthetic resin coating, civil water plugging grouting materials, building materials industry, improve the quality of cement, construction adhesive, caulking repair and plugging agent, soil improvement, electroplating industry, printing and dyeing, etc.

 

6, anionic polyacrylamide in mining, coal preparation industry can be used as mine wastewater, coal washing wastewater clarification agent.
