Polyacrylamide(PAM)/watertreatment agency
1) Appearance: White powder/ granule
2) flocculation, settlement, reinforcing
3) ISO 9001:2000 STANDARD
4) water treatment chemicals
Physical property:
Polyacrylamide (PAM) is a linear polymers formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked. It solubles in water, its almost transparent solution of the viscous liquid, non dangerous goods , non-toxic, non-corrosive.
Spcification:
Appearance | White granule |
Molecular weight | 5-22 million minimum |
Granule | 20-100 mesh |
Solid content | 88% minimum |
Hydrolyzing degree | 10-20%,20-30%or30-40% |
Dissolving time | Half an hour-one hour |
insoluble | 0.5%maximum |
Monomer free | 0.05%maximum |
action principle:
1)Flocculation theory.
2) Bridging adsorption.
3) Surface adsorption.
4)Enhancement.
Applications:
1) flocculate or coagulate solids in a liquid. This process applies to wastewater treatment, and processes like paper making.
2) subsurface applications such as Enhanced Oil Recovery. High viscosity aqueous solutions can be generated with low concentrations of polyacrylamide polymers, and these can be injected to improve the economics of conventional waterflooding.
3) soil conditioner. It is often used for horticultural and agricultural use. The anionic form of cross-linked polyacrylamide is frequently used as a soil conditioner on farm land and construction sites for erosion control, in order to protect the water quality of nearby rivers and streams.
4) the potable water treatment industry. Trivalent metal salts like ferric chloride and aluminium chloride are bridged by the long polymer chains of polyacrylamide. This results in significant enhancement of the flocculation rate. This allows water treatment plants to greatly improve the removal of total organic content (TOC) from raw water.
5) molecular biology applications as a medium for electrophoresis of proteins and nucleic acids in a technique.
Usage:
1) Through the test, determined the best model and the best dosage of the product.
2) Make the product up to 0.1% (refers to the content of solid) concentration of aqueous solution.
3) Enter this product evenly into the water and stir.
