What is the function of EDTMPS

 EDTMPS， Ethylenediamine tetramethylphosphonic acid sodium is a nitrogen-containing organic polybasic phosphonic acid mainly used as a cathodic corrosion inhibitor. Compared with inorganic polyphosphates, it has a higher corrosion inhibition efficiency, about 3 to 5 times higher. EDTMPS is miscible with water, non-toxic and pollution-free, with good chemical stability and temperature resistance, and can maintain its scale inhibition effect even at high temperatures of 200 ℃. In aqueous solution, EDTMPS can dissociate into 8 positive and negative ions, forming chelates with multiple metal ions, thereby disrupting the normal crystallization of calcium scale and exhibiting good scale inhibition effects on calcium sulfate and barium sulfate scales. The main uses of EDTMPS include as a corrosion and scale inhibitor for circulating water and boiler water, a chelating agent for cyanide free electroplating, a chelating agent for the textile printing and dyeing industry, and a...

多元醇磷酸酯 PAE

  Performance and Usage : PAPE is a novel water treatment chemical with good scale inhibition and corrosion resistance properties. The introduction of multiple polyoxyethylene groups in the molecule enhances its corrosion resistance and the ability to disperse calcium scale and suspended solids. It effectively inhibits the deposition of barium and strontium scales, which are challenging for existing scale inhibitors, and also provides excellent scale inhibition for sparingly soluble salts like calcium carbonate and calcium sulfate. PAPE offers cathodic protection for steel and is more effective than similar products available domestically. It is miscible with polycarboxylate, organophosphonates, inorganic phosphates, and zinc salts, making it versatile for use with other water treatment agents. The product is suitable as a scale inhibitor for oilfield water injection and as a corrosion and scale inhibitor for circulating cooling water treatment. Technical Specifica...
