PAPE is a new kind of water treatment chemicals, has good scale and corrosion inhibition properties. Since the introduction of the multiple molecular polyoxyethylene not only improve the corrosion performance, but also improve the scale of calcium scale and decentralized capacity sediment. Barium inhibitor existing domestic water beyond the control of scale deposition of strontium has an excellent inhibitory effect on water, calcium carbonate, calcium sulfate deposition of insoluble salts also has excellent scale inhibition effect on steel with cathodic protection , corrosion better than the existing domestic similar products. Polyhydric alcohols and polycarboxylic acid ester salt, an organic phosphonate, an inorganic phosphate and zinc salt in water-miscible good stabilizer. PAPE for oilfield acquisition inhibitor (especially recommended as a substitute for Nalco Visco 953) and industrial cooling water corrosion inhibitors.
Calcium carbonate, calcium phosphate, calcium sulphate scale inhibition performance is excellent, and can effectively inhibit the formation of silica scale, and has a good role in stabilizing metal ions such as zinc, manganese and iron. PAPEMP salinity scale inhibitor for reverse osmosis membrane systems, multi-stage flash systems high, high turbidity, temperature scale and corrosion inhibition system (such as systems scale coal high temperature and high turbidity water vaporization system), textile assistant agents and paper additives (yellowing inhibitors), can replace EDTA, DTPA, NTA, etc.

The equilibrium dissociation EDTA
In aqueous solution, 2 H + transferred to the carboxyl group N, forming a bipolar ion:
EDTA H4Y said common due to its solubility in water and an acid in a small, commonly used for the disodium salt: Na2H2Y · 2H2O, also abbreviated as EDTA.
When the high acidity of the solution, the two carboxyl groups may be longer accept H +, formed H6Y2 +, the equivalent of a six-membered acid, has six dissociation constants:
Ka1 = 10-0.9; Ka2 = 10-1.6; Ka3 = 10-2.1; Ka4 = 10-2.8; Ka5 = 10-6.2; Ka6 = 10-10.3.
