product description
Anionic polyacrylamide (APAM) is a water-soluble polymer, mainly used for flocculation sedimentation of various industrial wastewater, sedimentation clarification treatment, such as steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other sewage treatment, sewage Mud dehydration and so on. Can also be used for drinking water clarification and purification. Because of its molecular chain contains a certain number of polar groups, it can adsorb the solid particles suspended in water to make the bridge between the particles or by charge neutralization of the particles to form a large flocculation, it can speed up the suspension particles The settlement, there is very clear to speed up the solution to clarify, promote filtration and other effects.
Features
Clarify the role of purification
2. Sedimentation promoting effect;
3 filter to promote the role;
4. Thickening effect and other effects. In the waste treatment, sludge dewatering, mineral processing, coal washing, papermaking, etc., to fully meet the requirements of various fields.
Instructions
1, when used, dubbed 0.1% concentration of aqueous solution, to use neutral salt free sundries of water is appropriate.
2. When dissolved, the anionic polyacrylamide product evenly into the stirring water, stirring control at 100 ~ 300rpm. Appropriate heating (<60 ℃), can accelerate the dissolution.
3. Adjust the PH value of the solution to be treated, so that the anionic polyacrylamide product fully play its role (through the experiment choose the best PH value and the amount of this series of products.)
4. When adding anionic polyacrylamide solution, accelerate the mixing with the liquid to be treated. After flocs appear, slow down the stirring speed to facilitate the growth of flocs and accelerate the settlement.
Packaging, storage
Using 25KG lining plastic woven bags or paper-plastic bag, can also be packaged according to customer needs. Storage, pay attention to heat, moisture, prevent damage to the package, long-term exposure of dry powder products will absorb moisture caking. Stacking layers can not exceed 20 layers. The validity period is 2 years. The product size of 20-80 mesh, can also be produced according to customer requirements.
