What are the main industrial applications for EDTMPS?
EDTMPS (Ethylene Diamine Tetra Methylene Phosphonic Acid Sodium Salt) is mainly used in the following industrial fields, especially related to water treatment, corrosion prevention and cleaning:
1. Water treatment
Anti-scaling and dispersing agent: EDTMPS is widely used in the field of water treatment, especially to prevent scale formation. Metal ions (e.g. calcium, magnesium, etc.) contained in water react with carbonate and sulfate to form precipitates, which tend to accumulate on equipment and lead to scaling.EDTMPS prevents metal ions from precipitating by chelating with them through its phosphoric acid group, inhibiting scale formation and keeping water clean.
Boiler water treatment: scale often accumulates in boiler systems, affecting heat exchange efficiency and even damaging the boiler. edtmps can inhibit scale deposition in boiler water, preventing it from damaging the equipment.
Cooling Water Systems: In cooling water circulation systems, EDTMPS prevents scale and rust from forming on metal surfaces by binding with metal ions in the water, keeping the system operating efficiently.
Membrane protection and cleaning: In water treatment membrane systems such as reverse osmosis membranes, EDTMPS can effectively disperse particles in the water and prevent them from being deposited on the membrane surface, protecting the long-term service life of the membrane.
2. Petrochemical
Oil field water treatment: In oil field mining, water often contains a large number of calcium and magnesium ions, which is easy to form scale, EDTMPS can effectively prevent these metal ions from scaling, to protect the normal operation of oil field water treatment system.
Oil and gas separation equipment protection: In the process of oil refining and natural gas treatment, EDTMPS is also used to prevent the formation of scale within the equipment, especially in heat exchangers and cooling systems.
3. Corrosion protection
Metal corrosion prevention: EDTMPS can be used as an anti-corrosion agent, especially in industrial cooling water systems and boiler systems, to help reduce oxidized corrosion on metal surfaces. By forming a thin film, it protects metal surfaces from harmful ions and chemicals in water.
Anti-corrosion agent in water treatment: In addition to the anti-scaling function, EDTMPS can help prevent the growth of microorganisms in water and avoid the corrosion of equipment by biofilm.
4. Washing and descaling
Industrial cleaners: EDTMPS is also often used as an ingredient in industrial cleaners, especially when removing scale, deposits and rust during the cleaning process. Its dispersing action helps to clean out deposits from hard water and keep equipment clean.
Boiler descaler: It is used to remove accumulated scale in boilers and restore boiler heat exchange efficiency.
5. Coatings and paints
Anti-corrosion paint additive: EDTMPS is used as an anti-corrosion additive in paints to protect metal surfaces from corrosion, especially in metal structures such as ships, pipelines and bridges.
6. Other industrial applications
In synthetic chemical reaction: EDTMPS, as a chelating agent, may play the role of stabilizing metal catalysts or intermediates in some synthetic chemical reactions, preventing metal ions from adversely affecting the reaction.
In agriculture: In some water-soluble fertilizers, EDTMPS acts as a chelating agent for metal ions, helping to maintain the stability and effectiveness of the fertilizer and avoiding the precipitation or failure of metal elements.
