Polyacrylamide MSDS polyacrylamide HS polyacrylamide CAS9903-05-8

 

1, product introduction: polyacrylamide is a water-soluble polymer. Because its molecular chain contains a certain number of polar groups, it can make particles bridge by adsorption suspended solid particles in water or condense particles to form large flocs by charge neutralization. Therefore, it can accelerate the sedimentation of particles in the suspension, and has a very obvious effect of speeding up the solution clarification and promoting filtration.

 

2, product features: L, cationic type, anionic type, non-ionic type, amphoteric ion type, complete varieties and specifications, can meet the needs of all aspects. 2, water solubility is good, can also be completely dissolved in cold water. 3, add a small amount of this series of products, you can receive a great flocculation effect. Generally, only 0.01-10 PPM (0.01-10g /m3) is needed to give full play to the effect. 4, using this series of products and polyaluminum chloride at the same time, can show a greater effect.

 

3, function: this series of products flocculation effect is very strong, because it has: L, clarification purification effect; 2. Settlement promotion; 3. Promoting effect of filtration; 4, thickening (thickening) and other effects. In wastewater, waste liquid treatment, sludge concentration and dehydration, drilling mud additives, mineral processing, coal washing, papermaking and other aspects, can fully meet the requirements of various fields.

 

4. Method of use: 1. When used, it is suitable to use neutral water without saline sundries. 2. When dissolving, evenly sprinkle this series of products into the stirred water, stirring speed is controlled at 100-300rpm, appropriate heating (< 60 ℃), can accelerate the dissolution. 3, adjust the PH value of the treated liquid, so that the series of products to play a full role (through the test to choose the best PH value and the amount of the series of products). 4. When adding the solution of this series of products, the mixing with the treated liquid should be accelerated. After the occurrence of flocculation, the stirring speed should be slowed down to facilitate the growth of flocculation and accelerate the settlement.

 

5, packaging, storage and precautions: use 25Kg plastic lining woven bag or paper-plastic composite bag packaging, but also according to user requirements packaging. Polyacrylamide itself is not toxic, only when inhaled more than five per thousand due to gastrointestinal mucosa absorption of nutrients is sticky and harmful. The residual acrylamide monomer in polyacrylamide is toxic, and food application should be strictly controlled. When storing and transporting, pay attention to prevent heat and moisture to prevent package damage. Dry powder products will absorb moisture and agglomerate when exposed for a long time. Stacking layers shall not exceed 20 layers. Effective storage life is 2 years.
