EDTMPS is the same as EDTMPS; they are actually the same substance, namely sodium ethylene diamine tetra (methylene phosphonic acid) pentasodium salt. Therefore, there is no difference between EDTMPS and EDTMPS; they are simply different names for the same water treatment agent.
This substance is a highly effective corrosion inhibitor and scale inhibitor, suitable for use in various water systems such as circulating cooling water and boiler feedwater. Compared to other phosphate-based water treatment agents, it offers superior corrosion inhibition performance, excellent scale inhibition performance, good thermal stability, and high chemical safety. Additionally, EDTMPS is non-toxic and non-polluting, with excellent chemical stability and heat resistance. It can form coordination compounds with various metal ions, helping to disrupt the normal crystallization process of calcium scale.
Therefore, whether referred to as EDTMPS or EDTMPS, this substance plays a significant role in water treatment. In practical applications, the appropriate dosage and usage method should be selected based on specific water quality conditions and treatment requirements to achieve optimal corrosion inhibition and scale prevention effects.
