HEDP, or hydroxyethylidene diphosphonic acid, plays a vital role in a number of fields and has a wide range of applications.

In terms of the underlying mechanism of action, HEDP exhibits strong chelating properties due to its unique chemical structure containing hydroxyl and phosphonic acid groups. It combines precisely and strongly with metal ions such as calcium, magnesium and iron in water to form stable chelates. This chelating effect is like putting a “shackle” on the metal ions, preventing them from free movement and aggregation, thus effectively preventing the formation of limescale from the source. Once the scale is formed, it will adhere to the surface of pipes and equipment, which not only affects the heat transfer efficiency, but also may cause pipe blockage and equipment damage, and HEDP can precisely solve this problem.

In the industrial field, it is the “guardian angel” of the industrial circulating water system. Industrial production of a large number of water circulation, water temperature repeatedly rise and fall, the increase in impurities in the water, it is very easy to cause scale and corrosion problems. HEDP as a water quality stabilizer to join them, on the one hand, continue to inhibit the generation of scale, so that the cooling pumps, heat exchangers, pipelines and other key equipment free from scale trouble, and always maintain a high efficiency of the heat exchange efficiency, to protect the smooth production process; on the other hand, it can also be with the corrosion inhibitor tacit cooperation! On the other hand, it also works well with corrosion inhibitors to build a protective film on the metal surface, and HEDP strengthens this protective effect. Under the double guarantee, it greatly slows down the corrosion rate of the metal, reduces the high cost of frequent maintenance and replacement of equipments, and ensures the stable and efficient operation of industrial production.

In the central air conditioning water system, HEDP is also indispensable. Central air-conditioning operating conditions are complex and variable, the water temperature, water quality changes at any time, the water quality requirements are extremely high, HEDP with its own good adaptability, whether it is high temperature and humidity in the summer, or low temperature and dry winter, can flexibly respond to different water temperatures, water quality conditions, to ensure that there is no obstacle to the flow of water in the system, the condenser, the evaporator, and other core components of the heat dissipation is normal, so that air-conditioning system is always maintained in the best energy efficiency, reducing energy consumption, saving the user the energy. This reduces energy consumption, saves users money on electricity bills and extends the service life of the air conditioner.

For hot water heating systems, HEDP is the key to keeping residents warm through the winter. As hot water circulates in the heating pipes, the impurities carried in the water accumulate over time, which can easily lead to clogged pipes, corrosion and perforation, affecting the effect of heating, and the addition of HEDP can keep the water clean at all times, preventing scaling inside the radiators and pipelines, so that the heat can be uniformly and smoothly transmitted to each household, making the homes of the residents as warm as spring at all times. Moreover, it effectively slows down pipe corrosion, greatly extending the overall service life of the heating system and reducing the frequency and cost of maintenance before the heating season.

Compared with traditional water treatment agents, the advantages of HEDP are obvious. Compared with simple corrosion inhibitor, although it also synergistic corrosion inhibition, but more focused on scale prevention and control, with strong chelating and scale inhibition ability as the core competitiveness; compared with DTPMPA and other products with chelating ability, in the use of low-concentration scenarios, HEDP cost-effective and only a small amount of injection can achieve excellent scale inhibition results, saving a lot of pharmaceutical costs for the enterprise and the user, and really achieve high efficiency and economy. It is really efficient and economical.

In short, HEDP with its excellent performance, a full range of penetration into industrial production, commercial operations and daily life of various types of systems that require stable water quality, to become the mainstay of modern water treatment, and continue to create a comfortable and efficient production and living environment for people.
