water treatment chemical PAPE

PAPE
1. a new kind of water treatment agent
2. has a good scale and corrosion performance.
PAPE
Polyhydric alcohol phosphate ester (PAPE)


First, performance
Polyol phosphate is a new kind of water treatment agent and has a good scale and corrosion performance. Since the introduction of a number of molecular oxygen-vinyl, not only to improve the performance of corrosion, increased calcium on the scale of the scale and the spread silt capacity. Of the existing domestic scale inhibitors are beyond the control of the water, barium, strontium-scale deposition has a good inhibitory effect on calcium carbonate in the water, acid insoluble calcium salt deposition also has a good scale, with the cathodic protection of steel on the role of the , Internal corrosion is more effective than existing products. Polyol-phosphate and carboxylate, bisphosphonates organic, inorganic phosphate, zinc, and other water miscible good stabilizer.
Polyol phosphate used in oil field water injection agent acquisition of the scale (as recommended by the Special Nalco Visco 953 substitutes), the industrial cooling water corrosion and scale inhibitors.
Second, the technical indicators

Third, usage
As a result of water quality and conditions vary. Polyols used as a phosphate inhibitor, in general the amount of less than 15mg / L, used as a closed cycle inhibitor could be as high as 150mg / L and above.
Fourth, security
Polyol phosphate for the liquid acid, has a corrosive, they should pay attention to the use of protection.
Fifth, package and storage
PAPE is packed in plastic drum, and the net weight is 25kg or 250kg. In dry cool storage, the storage period is 10 months.
