In order to better development of the water treatment industry and meet clients’ requirements, IROCHEM has manufactured a series of new products. Such as ATMP, HEDP,  EDTMP, DTPMP, PBTCA, HPAA, PAPE and PAPEMP.

However, the study of organic phosphine inhibitors continues to develop. There are a lot of reports about organic phosphonic antiscale and corrosion inhibitors in China every year. Because of the kind of corrosion inhibitors have so many functions, such as scale inhibition, corrosion inhibition, antifreeze, and lubrication. They are getting more and more attention.

IROCHEM’s other organic phosphonic antiscale and corrosion inhibitors also have the advantages of high efficiency and good stability. The main types are polyamide, polyacrylic acid, polyether, and other phosphorous polymers. Scale inhibitor is composed of organic phosphine, fine copolymer and copper corrosion inhibitor. They have excellent corrosion resistance to carbon steel, COP and copper alloys.

And these scale inhibitors have good dispersion properties of calcium carbonate and calcium phosphate. IROCHEM’s scale and corrosion inhibitors are mainly used for the open circulating cooling water treatment system, especially for copper equipment system. HEDP can be used for high pH, high alkalinity and high hardness of water quality. It is one of the ideal non-ph alkaline treatment water treatment agents.

HEDP accounts for a large proportion of all organophosphate corrosion inhibitor products. HEDP is also one of IROCHEM’s main products. It is well known that HEDP is an organic phosphonic acid scale inhibitor. It can form a stable complex with metal ions such as iron, copper, and zinc. HEDP can remove and reduce metal ions in water very well. HEDP can dissolve the oxide on the metal surface.

It is still under 250 ℃ can play a role of good scale and corrosion inhibitor. Its acid and alkali resistance and chlorine oxidation are better than other organic phosphonic acids (salt) products. HEDP can form six ring chelates in water with metal ions, especially calcium ions.

The results show that the six ring chelates have a good effect of scale inhibition and obvious dissolution. When combined with other water treatment agents, the siX-ring chelate has the ideal synergistic effect. HEDP is not easy to hydrolyze and remains stable under high pH.

HEDP  is not easy to decompose under normal photothermal conditions. It is important to note that only high-purity solid HEDP products are suitable for use in cold winter areas. This solid HEDP is especially suitable for cleaning agents and daily chemical additives in the electronics industry.

In recent years, the demand for HEDP market in China has been increasing year by year. In 2017, the demand of HEDP in China is about 1456,000 tons. And it is estimated that the HEDP acid demand will reach 2608,000 tons by 2020.

HEDP is short for hydroxyethylidene diphosphonic acid. Hydroxyethylidene diphosphonic is widely used in petroleum, chemical, metallurgy, transportation, light industry, textile, and other industries. HEDP (hydroxyethylidene diphosphonic acid) can be used as a corrosion inhibitor, scale inhibitor, metal chelating agent, peroxide stabilizer, peroxide curing agent, complexing agent of electroplating industry, electronics industry cleaner, and daily chemical additives, etc.

In practical applications, HEDP acid and other water treatment agents have a better synergistic effect when used in combination. For this reason, it is important to note that the antagonism between the components is due to improper compounding. That will cause the effect to be reduced or lost. At the same time, we should make full use of the synergistic effect to increase the HEDP effect.

In addition, most water treatment systems are open systems. These systems have a certain amount of emissions. Therefore, when using HEDP, you should consider the impact on the environment.

Common HEDP products and its salts include HEDP 30, HDEP 60, HEDP liquid, HEDP solid, HEDP Na, HEDP Na₂, HEDP Na₄, HEDP Kx, etc.

HEDP (Hydroxyethylidene Diphosphonic Acid) is an odorless organic phosphorus chemical compound. For one thing, it is colorless to yellowish acidic liquid.

In recent years, the demand for HEDP market in China has been increasing year by year. In 2017, the demand of HEDP acid in China is about 1456,000 tons. And it is estimated that the HEDP demand will reach 2608,000 tons by 2020.

The formation and development of the water treatment industry are accompanied by the rapid development of the economy and the process of urban industrialization. The shortage of water resources and the enhancement of human environmental awareness provide the driving force and a huge market for the development and growth of the water treatment industry.

HEDP is the development of China with the introduction of modern water treatment technology and development. HEDP developed later than developed countries, but it is growing fast. It has developed a system of independent development and industrialization of various water treatment reagents including HEDP.

The development of Chinese water treatment agent can be divided into two stages. From 1974 to 1989, the first stage was the introduction of absorption and localization. The goal of this stage is to establish a research and manufacturing system for water treatment in China. From 1990 to 2000, the second stage was the innovation and development and industrialization. The goal is to establish a water treatment agent and technology system with independent intellectual property rights in China.

So far, China has more than 100 kinds of water treatment products, such as HEDP and DTPMP. HEDP and HEDP salts have basically met the domestic demand from production to quality and can also be exported. Technically, some production technology and performance have been at the international leading level.

Due to the huge potential of HEDP acid market, the industry competition is increasingly fierce. However, most enterprises are small in scale and low in technology. And the product homogenization is serious. The competition in the industry is mainly reflected in the quality, brand and marketing channels. Among this competition, brand formation is a long-term accumulation process. And the brand competition is also a comprehensive reflection of the competition in hydroxyethylidene diphosphonic acid industry.

New enterprises continue to enter the water treatment industry. HEDP market has a new development situation. Upstream raw material prices continue to rise, leading to lower industry profits. Therefore, the market competition in HEDP industry is increasingly fierce. IROCHEM focuses on innovation. In order to develop better, IROCHEM fully understands the development of the industry and our position in the industry. IROCHEM will provide high-quality products and services to global partners.
