Properties
The ATMP molecular structure have C-P Chemical bond so it has good chemical stability and is hard to be hydrolyzed in water system. At the 200°C high concentration, it has good corrosion inhibition,good stability,have an excellent effect on calcium carbonate scale.And can be with iron, copper, aluminum, zinc and so on many kinds of metal ions to form stable complex, good dispersion properties. When the dosage of more than 40ppm, but also has good corrosion performance. And this product is non-toxic, pollution-free pharmaceutical.
Usage:
ATMP mainly uses in the thermal power plant, the refinery and so on opens wide in the type circulating cooling aqueous system to make the antisludging agent, with oil field reinjection aqueous system antisludging agent.ATMP also available makes the printing, the textile profession metallic ion chelating agent and the fixing agent, the galvanization complexing agent and the metal boiler scale cleansing agent

Using method:
ATMP is usually used together with organophosphoric acid, polycarboxylic acid and salt to built all organic alkaline water treatment agent. ATMP can be used in many different circulating cool water system. The dosage of 1-20mg/L is recommended. As corrosion inhibitor, the dosage of 20-60mg/L is preferred.
