Polyhydric alcohol phosphate ester(PAPE)

Polyhydric alcohol phosphate ester(PAPE)

Structural Formula:


1, Properties and Uses

    Polyhydric alcohol phosphate ester PAPE is a new type of water treatment chemicals, has good scale and corrosion inhibition.Since the introduction of a number of molecular poly vinyl, not only improved the corrosion performance, but also enhance the inhibition of calcium scale and sediment dispersion capacity.Inhibitor of the existing domestic water beyond the control of barium, strontium has a good scale inhibition of deposition of calcium carbonate in water, insoluble calcium sulfate salt deposits also have excellent scale inhibition effect on steel with cathodic protection , corrosion better than similar domestic products available.Polyol phosphateand polycarboxylate, organic phosphates, inorganic phosphate, zinc salts and other water miscible good stabilizer.Polyhydric alcohol phosphate ester PAPEcollected for field scale inhibitor injection (recommended as a substitute for Nalco Visco 953), industrial cooling water treatment corrosion inhibitor.

2, Specification:

3, Usage:

Water quality and process conditions vary.Polyhydric alcohol phosphate ester PAPEused as scale inhibitor, less than normal amount of 15mg / L, when used in closed loop corrosion inhibitors can be up to 150mg / L or more.Polyhydric alcohol phosphate ester PAPEacidic liquid, operation, attention to labor protection, should avoid skin and eyes contact, rinse with plenty of water after contact.

4, Package and Storage

Polyhydric alcohol phosphate ester PAPE packed with plastic barrel, net weight 25kg or 200kg.Storage for twelve months in room shady and dry place..

5,Safety Protection:

Acidity, Avoid contact with eye and skin, once contacted, flush with water.
